A Speculative Analysis About Irkens No One Asked For: Part I

Dem green fellas. Them lil guys, they’re an interesting pack of critters, aren’t they?

I used to really fixate on them back in middle and high school, stronger than everyone else seemed to be on the spazz in the dog costume. Jhonen Vasquez’s worldbuilding has always towed a very fine line between nonsensically ridiculous and surprisingly logistical, and this balance is typified in everything we know, and can infer, about these bug-eyed imperialists at the center of everything Invader Zim. So, let’s infer, and take a crack at it since no one’s stopping us anyway- More specifically, some thoughts and ponderings I had about how they “tick” as a fully realized society, not just a sci-fi monster..

A Homeworld Obscured 

Now, to really understand the history and “deal” of any civilization, or any animal, usually you would turn to their environment first to give you some handy clues and context.

Small problem, though: We actually don’t get much in the way of direct, explicit showing or explanations about Irk itself when it comes to the show. This makes some sense, given that the whole of what they do worth showing (and the most notable members of their kind) exists almost entirely off-world. So instead, we mostly find out more about Irk from what Invader Zim does tell us about its natives. As far as confirmed canon goes, we know that Irk’s atmosphere appears red, its surface is entirely and densely urbanized, and it’s long been depicted in starmaps with a set of Saturn-like rings. 

  This last fact is probably the most interesting, because planetary rings are usually something we, in our own little solar system, would only associate with massive, gaseous worlds, not terrestrial ones.  What These rings are made of is really anyone’s guess- could be ancient debris from natural satellites, Water-ice particles, maybe even some form of artificial defense network put into orbit by the Irkens themselves. If they aren’t artificially created, this would suggest that Irk has quite a strong gravitational field- greater than that of any of our neighborhood’s rocky planets. This is the common theory I personally like to subscribe to, because it would also go hand and hand with explaining why the average height of the irken race is so much shorter compared to that of an adult human. It fits neatly into the “why” question for the sort of athletic skill and agility we’ve seen invaders able to demonstrate on Earth, too, for otherwise being of meek physical prowess. It even adds some credible context for why the very achievement of growing to a more substaintial height is both uncommon and associated with extreme survival fitness to them.

A Fun fact that’s about to be relevant: “Rayleigh scattering” is the term given to when light wavelengths become shifted and scattered through an atmosphere medium. Long story short, it’s the reason our sky has color to it during the day. Stay with me on this.

I’ve also seen some people take a go at the red-looking surface, guessing a different gas makeup than the elements on earth responsible for our blue skies. I’m gonna go against the grain here, and actually contest that. I think that Irk’s atmosphere is coincidentally extremely similar to Earth’s. We know well enough that they both have a similar composition of gases breathable to both societies, given that Zim, Skoodge, and Tak all seemed pretty comfortable without some form of assistance on the same dirtball as humanity. Instead, I propose that Irk’s magenta skies are actually the symptom of heavy pollution. Sunsets and sunrises in the real world are known to make the sky appear more reddish-orange, even pink, as is. Usually, Rayleigh scattering has the light From the sun appear bluish in full midday, but during low sun, the rays are coming at an angle making them have to travel farther before reaching us, so you have already stretched light waves getting the same treatment from the air and, well, a higher frequency blue turns down to the lower end of the spectrum, red and yellows.

And wouldn’t you know, air pollution can actually do the same thing. THIS is why there's a scary ass orange haze known to accompany the presence of massive forest fires and volcanic eruptions. Earth’s most polluted cities even experience longer and redder sunsets for the same reason.

On Earth, Zim stared directly into the midday sun without hesitation, nor concern that it would literally blind him. I think the planet hue and this is plenty enough to guess the likely case that Irk’s surface probably doesn’t get a lot of direct sun on an average day as is, and the sheer amount of unbroken cityscape that covers the homeworld would be the more obvious suspect than just having a more distant star from them. If they overcrowded to the point of their expansion, why build their civilization deeper into the ground, instead of up? Maybe there's actually a good reason or two they don’t raise their young topside.

A Psychology Molded for Domination

As well, I want to chirp about real world space again for a second. So, anyone up to the buzz in geek circles and aware of the math on the matter probably got the memo: humanity is almost matter-of-fact certainly not alone in this sandbox of a universe (or at the very least, we won’t always be alone). Like, about as certainly as we were about Black holes’ existence before we up and observed the real thing. And while it’s probably not going to happen in any of our lifetimes, sci-fi and media generally have been trying to take a crack for years at what the theoretical first contact with an alien civilization is going to look like. 

And I’m gonna go ahead and say it, 

As “cliche” and Hollywood as the conquering little green/grey dudes trope might have become… it’s actually not a wild take after all. The little and green thing, that’s creative liberty, but the part about them being hostile and something we may not actually even WANT to be aware of our existence? That’s an idea that even the smarty pants experts have been fearing the realistic odds of, even including the late Stephen Hawking .

The Evolution of intelligent life is a hard thing to really pin down and predict, given that we literally only have the one example to study. Under the right conditions, what reason would another advanced species NOT have to be equally as expanding, as exploitative of its resources, self-destructively short-sighted, and as supremacist as humans have already demonstrated themselves to be capable of? There is a lot of very interesting literature that suggests BOTH empathy/altruism and or aggression/tribalism to be (at least in the short term) very rewarding characteristics for an intelligent social species to develop.

And that’s the thing about the behavior of the Irken Armada I think has always been fascinating. Their drive to be the biggest definitionally invasive species across the cosmos is framed exactly as irrational, bumbling, and pointless as it deserves to be; however, is it not just the extended conclusion of every empire that has existed here on Earth, if only it had survived long enough to achieve the technology of Irk? And yet, it’s reminiscent, like the rest of their design, to the far from sapient, yet very real world creatures they appear to be most inspired by: hive and colony building arthropods. Whether the next point I'm about to touch on should be seen as a rejection of that resemblance, or further elaboration of it is anyone's to answer.

Transhumanism, or.. Transirkenism, in this case?

Like the specifics of what Irk really looks like and how it realistically works, a bunch about the aliens’ physical biology is left to scattered tidbits to ponder and piece together into a bigger picture. A few of those tidbits are as follows, drip-fed to us over the course of aired and scripted but never released episodes:

+ From the mouth of Vasquez himself, it has been confirmed that Irkens lack any form of reproductive organs. Instead, they rely on industrialized facilities to grow and produce them in a factory sense.

+ Yet curiously, they still demonstrate something akin to sexual dimorphism, or at least the cultural existence of masculine/feminine genders, where females are aesthetically set apart by the presence of curled antennae, eyelashes, and higher voices.

+ Irken lifespans are able to stretch far past that of an average human’s (Zim himself is cited to be around 2 centuries old in earth years).

+ Invader class soldiers have been implanted with surgical upgrades to their eyes.

+ Every Irken is fitted with a PAK that serves a wide array of utility and life-sustaining functions for its owner. These units are physically and neurologically connected into an Irken’s spine from “birth” and contain a cybernetic backup of an individual’s personality, assigned occupational programming, and memories. 

That’s not close to a complete list by any means, but it’s got the gist of what I want to dwell on most, starting with the last bit; because the PAK isn’t done true justice in one statement. It is not an extra addition the way a prosthetic enhancement is, and it is not a tool the way armor and weapons are. It is literally analogous to a vital organ to these aliens, and they are shown to die within 10 minutes of being forcefully detached from their own.

The degree to which Irken bodies and minds rely on this technology, and how seamlessly they are integrated into it, ALONG with their completely artificial life cycle all directly points to the fact that their civilization has advanced into a cyborg-like stage of evolution. It may even be on track to reach a post-organical peak in due time, phasing out more and more of their “vestigial” and feeble meatsuits until they’ve become a true drone army. And that actually begs some huge questions now that we realize we will never know how much of the Irken anatomy was ever originally a natural feature. An Irken’s own brain practically comes secondary to the superior efficiency of the supercomputer on their back, capable of literally holding their own essence and being in the form of code. A code that can preserve the “self” even in the event of meatbody failure, being uploaded post-mortem into the Control Brains’ collective data and repurposed for a future generation of workers. It absolutely would stand to reason that the species has continued this biological self-tampering to other heights- extending their lifespans, incorporating untold amount of mechanical upgrades into their bodies, and maybe even genetically engineering their smeets to be so compatible with this technology.  The control brains themselves are a mesmerizing reflection of this change over time- the result of an evident shift long ago from technology serving them, to them serving the directives of computers. When you really pay attention to the control brains’ role in the series, it comes clear to you who (or what) is really in charge of their society. The Tallest still maintain their symbolic/cultural importance to the Irkens, but outside of their part in spearheading the active intergalactic invasion, they ultimately are figureheads when it comes to actually running the homeworld and ruling the lives of Irk’s inhabitants. If I had to bet money, I would say the Brains may even have the ability to choose and predetermine the next Tallest when a replacement is needed. But what does that make the Tallest? A meaningless title and transformation, chosen arbitrarily by the AI overlords? Well, I don’t think so, actually… but maybe that, and more on the “meaty” morphology of their race is all a tangent fit for another day and post ;)

The Speculative Analysis About Irkens No One Asked For: Part II

Hiya! Back at it again with not shutting up about the lil green dudes. In case you found this first, here’s the Part One of this spiel, touching on some of the environmental theories about Irk and its cyberpunk-leaning cultural direction. While this post is dedicated to a more biological look of what’s going on with the Irkens, there was some leading context and other tidbits back in that one you may also enjoy, too.

So, carrying through what we previously set up, I want to… admit off the bat that, I found it a little difficult at first, you know?-To pick an angle I wanted to sink my teeth into. With how old the show’s become and how creative & enthusiastic a fanbase it attracted, it’s getting hard to really note (or theorize) something about Irken anatomy that hasn’t been said before somewhere. And don’t get me wrong, that’s awesome and I love almost every word of it I’ve read. A lot of it from various sources is almost certainly going to bleed together into the first half of this. So, keep it in mind, yet I will try to chew a little deeper into the questions we can’t actually answer with just a rewatch of the show, all good? Because there’s a few more base things we know from the canon I’m going to include to start listing: - Irkens lack any visible form of nose or ears, but are equipped with a pair of sensory antennae. Presumably, these organs fulfill the same roles, as they do in real-world insects. - Irken organs are obviously very alien, not well explained, artificially enhanced, and hard to compare to that of a human’s- outside of their general body shape, the presence of a primary brain separate from the PAK, and the fact that they do possess something of an internal skeleton. - A petite race on average (relative to humans), Irkens universally follow an unquestioned social hierarchy based on individual height. - Irkens are endowed with a remarkable ability to regenerate and heal superficial injuries, even up to repairing the damage of being nearly skinned alive (chest-down) or severely burning their corneas within a matter of hours. - Their preferred diet is one that is rich in (if not primarily made of) refined carbohydrates, and while they seem to tolerate fatty sources, such as processed dairy, their anatomy is poorly suited for dealing with high-protein foods like beans and meat. - In fact, all forms of contact with exposed animal meat itself will cause it to dissolve and meld into their own flesh, via an incredibly painful process. - On contact with water from Earth, their skin will receive harsh chemical burns (This has been explained by Vasquez to be a consequence of impurities and man-made pollutants, which Irkens seem sensitive to). - While I’m already on a roll about their skin, it also contains/produces a substance capable of killing lice.

Now, I think we’ve all heard a lot about sqeedily spooches, but does anyone else want to keep marinating a second longer on the topic of s k i n ? Because I have some damn thoughts to release about Zim’s outer casing.

Let’s Get Chemical

First hot take, and the hill I am willing to be slain on: That ain’t actually skin! At least, it is nothing chemically alike to Earth-native vertebrate skin. I’ve given all of the above and the general running theme about Irkens resembling arthropods a lot of thought, and I’ve come to about the only conclusion I could that makes their dermis equivalent… make sense.

See, one of the biggest traits that sets apart invertebrates from other animals in real life is the “innie or outie” skeleton question, but you gotta understand that the “skeletons” that bugs and crabs have would still be considered something completely different from our endoskeletons even if they were on the inside. The hard tissues that make up OUR skeletal systems are mostly made up of a *collagen (remember that word!) frame that is reinforced by calcium, phosphorus, and other minerals. The hard parts of an ant’s skeleton, on the other foot, are mainly composited of chitin.

Chitin, now, is a very neat substance. It’s a polysaccharide, meaning that it’s made up of a bunch of sugar molecules chained together. This makes it distinct from proteins, which are made of amino acid chains instead of carbs. Chitin is also one of the single most important structural polymers in the universe to a ton of existing life. It makes up the literal backbone of arthropods and the cell walls of all fungi. We’ve even found it in fish scales and some amphibians. So, must also be important to humans, right? NAH. Not a chance. Higher animals actually long ditched the ability to synthesize the stuff, and are not any the worse for it, since there’s more than one way to stick a bunch of creature pieces together. For two examples, keratin and *collagen are proteins we naturally synthesize that functionally do the same thing. Keratin is the hard substance that makes up hair & fingernails, and collagen is practically the wonderglue of flesh: It’s a fundamental binder that holds together your bones, your skin, your precious muscle meats, the ligaments, the tendies, the nerves…

pretty much the whole person blueprint if you get the picture.

And thus concludes your (VERY overly simplified) highshcool bio class recap, but what the hell did that have to do with the cartoon spacemen again? I’m gonna round back to them through a funny secret about exoskeletons, actually: They have a softer part, too! Chitin’s hella diverse in its forms and utility. What’s in an exoskeleton is actually a version of it modified with other materials (like what’s done to collagen in bone) to make it so rigid and shell-like. A purer chitin, on the other hand, is more leathery and flexible, less like the shell of a beetle and more like the squishy wall around a caterpillar or maggot. Even the hard bodied insects still have an endocuticle layer like this hiding just under the “shell”, still considered part of the whole exoskeleton, but suddenly looking and acting more like we’d call a skin.

Eh, see where I’m going with this? My conviction is this- Irkens may have used to be even more arthropodal in an earlier stage of their evolution, including BOTH an internal skeleton, and some form of protective exoskeleton in their body plan. And hey, maybe the two were extensions of the same system once, too. You recognize something like that in modern tortoises when you remember that their “shells” are actually just the bone structure of their own ribcage. Then, let’s say that Irkens later saw the loss of their heavier exocuticle, leaving behind the endoskeleton and the flexible inner (now just an outer) cuticle of what used to be an entire body shell. This could have been a gradual change, via natural selection, or it could have been another artificial mutation brought on by technology- wherein the elder brains decided the feature was less efficient and simply phased it out of the cloning process- the same as the loss of their species’ sexual organs.

But, you’re thinking, why on Irk would the loss of an entire badass armor layer be beneficial to their fitness? Few reasons- For one, they are cumbersome and limiting. The downgrade on freedom of movement and flexibility they would be for a bipedal humanoid is self-explanatory enough. When it came to structural integrity, the inner skeleton would have already done a well job with little modification. For all the protection they provide, they don’t leave much room for expansion, and need to be shed in order for the animal to grow any further or to recover from certain injuries. The process of molting itself would be an excruciating process for any intelligent species to have to endure; one that also temporarily leaves the critter in a very vulnerable and stressed state for every molt. To advance from more primitive origins into a dominant race, manual dexterity and mobility would have to take a front seat over a small amount of modest defenses, and mind you, Irk long ago woulda managed to compensate for that loss in the form of advanced weaponry (obviously).

I’m also of the mind that the shift away from an exoskeleton could have even been the key to allowing the Irkens to even grow to the size they are now. Recall back to Part One for a second, where I shared the likely case for Irk having a massive bulk behind its gravity field. Gravity is a hard thing on any skeletal structure, representing a constant strain to be fought against when moving, growing, and bearing weight .There’s a lot of factors behind why we don’t have horse sized spiders or elephant sized lobsters IRL, and weight is actually one of them. Notice how terrestrial isopods only get about to the size of a bean, but the aquatic ones can top out at over a foot long? And that’s only having Earth’s level of gravity to struggle against, let alone however harsh the conditions would be on a larger planet. So, there’s my framework for explaining what I think the aliens’ cuticle is not; however, what does that mean for what it is, besides “feels and looks like a grub’s”?

Well, look again at some of the extraordinary things it can do.

Cooties Immunity

“Germs” was a memorable episode that posed a very legitimate question to the viewer. Why IS IT that foreign pathogens aren’t a bigger concern for the invaders? They’re literally sent off to other worlds to blend in: Socializing with the native inhabitants, eating their foods, and living in an alien habitat. In the case of an undiscovered rock like Earth, our infectious diseases would have no reference available to the Armada whatsoever. Sure, species incompatibility would provide some protection, but the risk of something carrying over and adapting is always still there. Zoonoptic jumps happen all the time with bacteria and viruses, and Zim’s body temperature IS in the normal human range. And what about fungal pathogens, or parasites-

Oh, wait, the lice episode gave it away right there.

I love this sequence so much, because it’s coincidentally like, an exact “art imitates life” parallel to something a real species of primate does. Black lemurs live in the same area of Madagascar as these vibrant, red millipedes.

The millipedes are special because when threatened, they secrete a poisonous substance from their skin. The lemurs are special because they like to grab the bugs and nibble them for no other reason than to make them release those toxins. Those chemicals are then rubbed into their fur, because somehow the lemurs figured out it makes a really handy mosquito repellant. The lemurs also like to get completely zonked out on the chemicals too but eyy- Point was it stands to reason that Irkens may also secrete small amounts of their own potent toxin from the cuticle, perhaps for more hygienic than defensive purposes. This secretion would be responsible for protecting them from parasites and topical infections. Could it also make people blazed out of their minds? …Maybe? I think I’d like to promote the “Just Say No” policy on the matter of licking aliens, though. Ffs at least ask them out to dinner first.

When it comes to other kinds of sick, looks like it might be the trusty old PAK to the rescue here again. I imagine that, being an intergalactic, partially mechanical civilization, the Irken race has come down this road enough to put in a workaround. A standard PAK contains the entirety of the population’s collective knowledge/history- which would include a catalog of all known infectious agents they have encountered across the universe. Some kind of nanobot-bolstered immune system that could detect and respond appropriately to new threats isn’t out of the question, nor should a feature that can automatically administer the appropriate medicine directly into the wearer’s bloodstream. For all this awesomeness, nonetheless, there remains a downside or two that they haven’t quite conquered..

The Meaty, Sweety, Mending of DOOM

Anyone ever actually think about how as far as resilience is concerned, Zim is practically an X-man compared to any Earthling? He has regenerative capabilities that surpass anything else on earth, save idk, bamboo shoots, if even. Injuries that would leave a human permanently disabled only seem to incapacitate an Irken for a few hours to a day at most. They’re all the more tough to put out of commission when considering that a PAK doubles as a form of backup life support, ready to “soft reboot” the host with a quick jolt if it detects a sudden drop in vital signs. It is tempting to credit the same device as the source of this healing boost as well, teasing the nanobot suggestion again; however, I see a chance instead to bring this back a step.

Although not as quick-acting as Zim, or Skoodge’s healing, there are some remarkable examples of regeneration in real arthropods, from repairing tissues/organs to replacing entire lost limbs. What the aliens are packing doesn’t seem all that different, only refined (through years of bioengineering) to work at a truly frightening efficiency. It shows through in their diet as well. Almost always, if we see a member of this species eating on screen, and believe me there was no shortage of examples, what are we watching them shovel their face with?

Space doughnuts, space popcorn, space Fun-Dip, sodas, and curly fries. Sure, there’s plenty of calories here, no doubt with the amount of carbs and grease that could even turn the stomach of a college freshman, but is this… nutrition?

Yes. Just not for us.

Like their civilization, we have also turned the mass production of sweet-packed, fat loaded foods into one of our favored art forms, and there are scattered pockets of our planet that can enjoy these items in cheap abundance. The catch 22? Obesity and heart disease. Meanwhile, Irkens are so metabolically blessed that they can follow the same lifestyle and actually be thriving by it. We know that the majority of human food is utterly toxic to Zim, but then there were waffles, a literal stack of dessert and butter that pretends to be a breakfast…. Our guy was experiencing the “finally some good fucking food” meme from the first bite off that plate, but this can’t seriously be healthy,or if it is, then how?

Well, if I did sell you on the idea that much of their tissues and skeleton swaps out a chitin base where we would be using protein, there you go. Sugars for the building blocks to synthesize the connective/structural tissues for maintaining the body, and the bulk of the energy required to keep it running. And I won’t make the leap and suggest that’s all they have.

After all, the Irken equivalent of sandwiches do actually seem to contain “lettuce” and something that people will say looks like meat slices while not convincing me. I can get behind the thought of the natural or maybe original Irken diet to be a mix of plant matter and supplemental fungi, but everything I’ve put together implies that they are completely unfit for processing the goodies in animal flesh.

Overwhelmingly, I believe that the only time they possibly even seek out more sources of amino acids is going to be when they are smeets. That’s how it works in many wasp species. I.e. The growing larvae are the only ones that actually get to reap from the hard work of a colony hunting down enough protein to feed them with, yet the adults live out the rest of their lives more than content to gorge themselves on nectars and fruits exclusively!

And you even could put that aside, but you’ll have to grapple with the ungodly thing that happens every single time you see Zim touching a piece of meat. Would be awfully convenient to blame it on his personal brand of weirdness, or earth contaminants, but we remember this was a weakness that Tak approached fully aware of and expecting.

We know that polluted water can burn them. We know that beans and other foods can give them grotesque allergic reactions. Well what in the horrifying name of Resident Evil is this, though? Buddy pals, I think we got some unintended consequences of that bio-hacking on hand. Collagen and chitin aren’t just functionally similar to each other, they are practically analogous building blocks.

For a WILD science fact, consider that there’s a ton of ongoing research into the application of chitin and chitin-derivatives into having a role in tissue engineering, as a hypothetical scaffold in lab cultured meat, and as an effective wound dressing ingredient.

What we’re seeing with incidents like Dib throwing that Bologna at Zim could be an extreme form of the vise versa, because I know a certain protein that processed meat happens to be pretty high in :)))

Imagine the coupling of this with the bioengineered genome of Zim’s kind being so… reactive to a foreign intrusion, yet also flexible to modification. Maybe it is the acids, or some contaminant/seasoning on the meat that first damages the cuticle. That healing ability kicks in, but doesn’t stop where chitin does, readily binding to and with the collagens in these strange tissues that are sorta like an Irken’s but also just enough not like an Irken’s that it also kicks the immune system into overdrive. Think of all the pain and inflammation of a poison ivy rash but if the damn plant itself could also fuse itself with whatever you brushed against it. I think Zim actually had an understandable reason to be homicidally pissed off for that Bologna assault. Also how the Bologna virus was accelerated in Zim’s body. Once it had incorporated itself into his own DNA, it was game set and match with the speed and help those cells had to replicate themselves.

And uh, yeah, I think this post has gotten about as long as it reasonably should be here. I did have a couple more points I really wanted to get out of my brain about the Almighty Tallest, and I think that would be a good launching point actually for a possible (and hopefully final jfc) part three to this. Till then I got some off-topic scoliids to taxidermy 👀

That Speculative Analysis About Irkens No One (Originally) Asked For: Part III

Hey! Huge thanks to everyone who took an interest in the first two parts of this fun I got into about Jhonen Vasquez’s funny green guys. I didn’t really expect to kind of rebound back into this old flame the way I have been lately and it’s actually a pleasant surprise that other fans have been getting something out of it and enabling my latest thinkworms.

Check out the part one of this extended analysis here, for broad tids and bits about Planet Irk and the mention of its inhabitants being basically cyborgs.

Part Two, takes on Irken physiology and focusing on their tissue differences from humans, here.

So alright, I’ve been holding this one in since the very start. Previously, I brushed the topic of the control brains, and I’ve sorta gestured acknowledgement toward the Irken obsession with height. Now, I’m really ready to get some thought goo flowing all over and in the crevices of the matter of Irk’s power structure, and, perhaps the one social W that this marauding pack of space imperialists get to claim.

Bearing no further ado, let’s talk about the Tallest. Can we talk about the Tallest? Please Mac, I’ve been dying to talk about the Tallest with you all day.

I’ve said once and now repeated twice that I think the canon implied that the homeworld of our favorite invaders is dummy thicc; consequentially, it’s left a lasting ripple on the evolution of their species as well.

Planetary gravity has a ton of invisible effects on the skeletons of large fauna, to the point where it’s the main thing that you, filthy Earth creature, can shake your own fist at it for taking a huge slice of the blame behind the prevalence of back pain in upright hominins. All that downward tug can really wear a spine down good over the years. In fact, would you believe that astronauts actually grow a smidge taller in Zero-G environments? Legit. So… use your brain and consider what we could have ended up looking like with our same bone structure, but many times that compression.

You take that mental path, and suddenly, height outcomes may not seem like such an arbitrary measure of general survival fitness after all. Especially in the days before the Irkens represented an intergalactic super power. It may seem counterproductive in their modern intelligent society, but no doubt this aesthetic affinity is something that runs much deeper ingrained than practical programming. Respecting tallness is something Irk takes on dogmatic intuition- to the fault of barely being able to comprehend the notion of another species being both tall AND intellectually primitive.

Nevertheless, I pose that the connection may also be more than traditionalism, and not so vestigial after all. My reasoning suggests that The Almighty Tallest are in fact, not randomly born… they’re planned and made by the real overlords sitting atop the pyramid. And even so, they have existed in the species long, LONG before the PAK even did.

• Caste Polymorphism & Bug Stuff

The insectoid inspirations of Zim’s kin are something so obvious they really need no recapping, yet, I’m pining to make a more specific comparison. Some people like to go for wasps or bees, but if you ask me, the roving militarism of the armada is begging for the ant metaphor if anything.

And I got a hell of a species to whip out that you’ve probably never heard of.

A quick context breakdown- Polymorphism is another one of those long biology terms for a pretty simple concept: when one species has different distinct forms or types of forms that appear in its population. And it’s not talking about continuous spectrum differences like height alone. It’s talking about when animals/plants can have one gene with different possible phenotypical presentations. One good example (in humans no less) is the existence of different blood type groups. One of my absolute favorite cases, by the by, is in Side-Blotched Lizards. The females are samey and look pretty generic, but the males deadass come in 3 completely differentiated color variants, all of which are playing a perpetual game of rock paper scissors with the other two for breeding success.

And this kind of phenomenon of course gets way less subtle in the insect world. Everyone here probably knows the simplified version of what a colony critter’s caste system looks like, with sterile female workers, breeding done males, and one big fat queen at the top, pumping out replacements for the other two. This is the part where I tell you it’s a hell of a lot more complicated, weird, and varied than that, actually.

Consider army ants, as I see them, the most Irk-ish of real world animals. Some fun facts on the most notorious handful of species below:

+ Nomadic by nature, they do not build any form of permanent hill or nest, and instead make temporary pit stops inbetween periods where the entire colony swarms along the forest floor in search of resources.

+ Army ants are aggressively predatory and forage in the style of legion-like “raids” that overwhelm their prey with sheer numbers and speed.

+ These raids often take shape by way of linear traffic columns that guide the direction of the swarm. This is because the ants have poor vision, relying on following the paths of the scent trails of the workers that are spearheading the legion.

+ Eciton burchellii, in particular, demonstrates a stark example of polymorphism by way of a rigid caste hierarchy. I.e., The non-reproductive colony members are divided into 4 sized tiers of worker. From smallest to largest there are minors, medias, porters (sub-majors), and soldiers (majors).

And let me tell you… the difference between the Soldier (major) caste and the rest of that batch is a pretty surprising gap.

This is what ONE major-type ant looks like hanging out with colony mates from the lower worker castes.

Oh wait, getting ahead of myself. Ahem… sorry, I meant THIS is the image I was referring to:

Not only is that obviously the bossiest bitch of the bunch, but she has some pretty cool features unique to her status… The more spidery looking body shape and those absolutely wicked mandibles being a standout.

You know what drop I already had coming, so I’ll cut to the chase.

It’s clear that the Almighty Tallest are NOT the Irken equivalent of a hive queen. They are not drones, either. Besides the glaring fact that they are non-reproductive individuals, the role they serve in Irken society has very little if anything to do with running the day-to-day lives and functions of the larger population.

Instead, we have always seen them (and would have seen them more in the unmade episodes such as The Trial) involved more with the military front of the empire. Tallest Miyuki’s one known planned appearance would have featured her overseeing the military research happening on the Vortian base. Tallest Spork’s brief entrance (and exit) was planned to take place on Devastis, where he addressed those who were being evaluated to join the elite ranks of the armada. And our very own iconic duo have,

also,

never even once been seen on their home planet since their introduction. Their first appearance? Conventia. Ever since? Aboard the Massive, where they directly command and supervise the operations of the active invasions.

Why, the Almighty Tallest in all cases… these aren’t emperors at all, they’re generals! Sure, they have power, they have reverence, but even they must obey the final judgement of a Control brain at the end of the day. The same brains that grant them their status in the first place. Note, in real ants, the mechanics of how exactly any one egg is differentiated into its decided caste, from worker to queen, and all between, is… to say the very least, really fucking complicated. And all over the place. Broadly speaking, it’s a mix between genetic potential and nutrition during development. In some species this determination is near entirely up to the whims of DNA, and in others, it does come heavily down to how many protein shakes the colony decided to give their brood that day.

For the purposes of this hypothetical, I’m going to assume the people of Irk fall somewhere in between those two polar options. Now, being a futuristic network of coordinated supercomputers using cloning tech, the control brains have a more precise handle on the gene pool/diversity of their underlings than anything possible with natural breeding.

Let’s also assume they record and monitor the current population of each potential class of irken (they literally assign and code the PAKs’ occupational roles themselves). With each batch of smeets, they can predetermine certain percentages aside with the potential to fill whatever roles need replacing and expansion… keeping the genetic height markers attached for those downline to understand who should be looking down on who. Ergo, not ANY Irken can one day become the almighty tallest, but within each generation of smeets produced, there are potential candidates hidden among the upper ranks of would-be soldiers.

This way, the sudden death of the current armada commander would not disable current operations or throw the offensive lines into utter chaos for years on end. The Control brains need only select out the cream of the crop from their “proto-Tallest” and then cue their body (via diet or hormones) to switch the proper genes on, get a new growth spurt going, and complete the metamorphosis into their true potential.

As for why they seemed to break a historical precedent and jump for a two-for-one special in Zim’s generation… yeah, I’m not sure about that really. There could be a link between that and the very sudden death of the two previous tallests in a row, but ¯\_(ツ)_/¯. It could just be a remarkable coincidence that Red and Purple were decided to be equally viable successors. Or, Operation Impending Doom could have been deemed an ambitious enough endeavor to warrant the appointing of two regents at once, given the scale of Irk’s expanded army for the purpose.

So, that’s it, then? The Irken species became so reliant of their technological advancement that they have casted aside and replaced every bit of their natural life cycle and order some

computer deemed inefficient? Substituted the seat of their leadership and even their ability to procreate with the soulless calculations of their AI programs?

:y Well, yes, but actually no.

• Long Live the Cyberocracy!

When I said in part one that Irk was on track to eventually make the jump from cyborg citizens to an entirely mechanical or digitized lifeform, I was doing a ponderous thinking thing. I was supposed to just be speculating, and then I find out the most mind blowing revelation while doing the research for this bad boy- those alien bastards already did it. The madlads/madlasses… So, living Irkens DO actually run the show around here, hiding in plain sight this whole time.

I am still desperately searching for confirmation of the rumors I heard that Vasquez himself has said what I’m about to share, and I deeply appreciate anyone who can give me that as well. Even if this turns out to only be fanon, I’m still in love with this interpretation anyway: Within the Control Brains are the preserved consciousness of Irkens who have achieved this evolutionary end stage. WHO are they exactly is… honestly anyone’s guess. The important part being that they no longer have need of their meat suits to survive any longer and now exist as these hulks of nerve and metal.

Be this what it looks like to me, and it would be certain that this is actually the most coveted and honorary fate of any single Irken- immortalized and given a status on par with deification over the most powerful imperium the cosmos has ever known. Perhaps this was the path of particularly accomplished Tallests of the past, who had their paks integrated into the core of a fledgeling new control interface. What better way to commemorate those who have fallen in the highest level of glory? A single “brain” could in fact even be the summation of multiple beings, making example of the greatest the species has to offer and what all should be striving for. Conversely, the greatest punishment of their kind is the opposite- to be forever deceased, forever forgotten, forever excluded from this collective transcendence:

Damnatio Memoriae.

(But like… in a kids’ show)

There’s no clear estimate on how many control brains exist in the franchise, there are at least four that we have seen on screen, one on Devastis and the others within Judgementia. Probs safe to assume there’s at least one permanently built into the infrastructure of any planet of key enough importance to the Empire. Interestingly, lost scripts and show canon make numerous references to them still having gendered pronouns and voices when addressed individually.

Though, now that I think of it, that’s also really interesting that the same is true for the worker castes, too.

• Putting the “Trans” in Transirkenism 👉😎👉

When a worldbuild goes so far as to explicitly confirm a completely sexless, alien race of neuter cyborgs, the existence of a human-like gender binary starts to beg for some kind of explanation. You can’t just “suspension of disbelief” it aside the same as you can the fact that English is the most popular first language across the Galaxy.

Oh, lookie, it’s one of my favorite things to think about when toying around with postbiological concepts/philosophy. I knew there were even more reasons transhumanism always seemed like such a cool sci-fi trope, from the endless possibilities in imagining the badass super powers, to the worlds of knowledge, and to the absolute social equalization that would all be unlocked in a cybernetic future. Well, that future is already comfortably in the hands of Irk, and whether intentionally or not, it has apparently brought them to the threshold of not just a postorganic, but also a post-gender society too.

A feminine and masculine variation does still exist in the form of small aesthetic differences- voice, antennae shape, pronoun usage, and eyelashes- but is now so far disconnected from the original associated sex roles that the distinction might as well be no more than a cosmetic preference. While “female” irkens are seen much, much more rarely than their counterparts, neither gender is treated differently from the other, and both have been spotted in occupations all the way up to invader elite and the Almighty Tallest.

This is a blending, of course, far beyond the insect-like caste system that itself did survive to the modern day, and that shows some truly impressive progress from what I imagine they were doing before.

Army ants, like all eusocial insects, are matriarchal; as in, where the females run the colony from top to bottom, while the males lead short runs of being mutilated by the workers, mating with the queen, and then dying shortly after.

In this headcannon narrative, it was almost certainly the male-associated gender Irkens who were liberated by the technological jump.

And that’s all sum purdy neat food for thought, huh ! ?

I’m gonna be real as hell with y’all like 90% of my unhealthy obsession with Irkens and their society stems from the borderline endless ways they accidentally parallel and mimic (to me) the illithids from DnD

Or maybe it’s actually the other way around considering which one I was exposed to as a child first…. Anyway

New (Cursed AF) Invader Zim Headcanon:

Barring the potential for major acute blood loss, Irkens can actually survive a full decapitation.

And I brought substance to make the case with.

Cockroaches, one of the most infamously durable of real life animals, can live for several days, sometimes even weeks without their head. And for the most part, they still even act like normal roaches- crawling about, reacting to touch, standing around, etc. it seems the only reason this eventually catches up to the critter is because no mouth = no way to keep bringing necessary food and water into the body. If that were bypassed, however, it stands to reason the little zombie could thrive just as much as a headed roach.

Almost disturbingly, the head itself can actually last a surprising amount of time solo as well. Experiments with decapitated roaches show that after body separation, roach heads can still move their antennae for hours before succumbing- much longer even if kept refrigerated and supplied with nutrients.

One of the neat things about roach bodies that makes such a feat possible is how their nervous system is set up- simplified ref against what yours looks like below

Now, anyone who has ever said a roach can survive for a while without its brain is not being entirely accurate. Functionally, they actually have two sort-of brains: the main point of nerve centralization is contained in the head, which for the most part is a primary brain responsible for movement coordination, certain technical functions, interpreting stimuli that comes in from the antennae, and more. The second main point of interest in this system is a series of nerve clusters running down the insect’s abdomen known as ganglia (singular: ganglion). These bundles of neurons are not exactly brains in their own right, but they do function as an extended CNS that handles the control over the digestive tract, reacting to stimuli, leg movement, and other more basic bodily functions. These can operate the body on a primitive level after the loss of the main brain, up until thirst/starvation begins to run the wind out of the sails.

You know what sort of creature actually DOES have two entire complete brains? One up top, and an auxiliary backup a little further down?

If you were nodding along and saying “irkens!” Then you would be correct! One peanut and five more days in the bunker for you 🥜 ~

As is obvious to anyone familiar with the show, the PAK is an essential cybernetic addition to Irken biology, holding their gear as well as an entire digital backup of their personality and memories. While it serves many functions to the user, the first and foremost priority of one is to protect the existence of the meaty entity it needs in to carry itself around.

To that end we’ve seen some autonomous acts from time to time with Zim’s close calls. If you recall “Plague of Babies”, he… kind of died for a moment there, caught up in a wave of GIR’s lethally amplified stupidity. In response, his PAK appears to resuscitate him with a quick jolt. The would-be events of “10 Minutes to Doom” emphasize the necessity of the PAK for any Irken’s survival beyond several minutes, which directly implies PAKs facilitate a major biological process their natural bodies are no longer capable of alone. Personally, I think it might be something either neurological or related to respiration, on a hunch.

Well, whatever it is, they are toast without it in swift manner, and the PAK doesn’t prefer to be without its other piece anymore than the body does. Dib’s revelation about the technology described their relationship with its body like that of driver and car, but I think he’s missing something. The PAK is actually more than capable of carrying itself around without the body… at least for a time.

When I think about those things, a little dilemma pops up in my head concerning how they.. well, how they’re powered. It is never explained or demonstrated that they are given time off of the body in order to charge; however, irkens are probably advanced enough to have some smaller and sci-fi wildly potent and small energy source up their sleeves, but actually, that wouldn’t quite make sense here. Because Irken bodies still produce their energy the same way every other lifeform in the known galaxy does, with food. Lots of food, actually. They can mow through snacks at about the same rate as Augustus Gloop. PAKs don’t need to produce their own independent energy source, they just need to efficiently make use of what this organism is already evolutionarily fine tuned to do naturally. Now that’s smart engineering.

And so, like any respectable auxiliary life support feature, they hold some of that energy in a reserve for those crisis moments like in “Plague of Babies”, and also in a deleted scene made for “Abduction”!

Fun trivia fact, but originally that episode was supposed to feature a sequence where Zim nearly game overs again. He takes a gnarly hit and a literal plunge through open flames that knocks him out in a free fall.

Despite his incapacitated state, the PAK extends its spider legs in order to catch a walkway railing, both saving his life and proceeding to keep carrying his limp body to a safer location, until of of course, he comes to about a moment later and carries on.

And neither of these are the only times it’s sprung into action the moment it detects something has gone horribly wrong. When accidentally detached from its own host, an emergency response will be triggered within the PAK in an attempt to reattach with its body. Failing that, it attaches instead to… well, whatever it can find.

In “10 minutes to Doom”, this was unfortunately Dib, an incompatible match (or maybe it just picked an improper attachment site), and in the comics… things got interesting at a point or two.

So, I already know what happens when you separate an Irken from their spinal brain, but what about the cranial one?

Because, they actually don’t seem on the same level of urgent necessity? Now that I think about it?

The time machine kerfuffle and the brain eating parasite escape were both events this guy evidently survived, albeit not comfortably or ideally until the problem was fixed (I have to assume in part with GIR’s or the Computer’s help). Now that I think about it Zim’s incredibly fortunate that most of these more serious mishaps happened inside of his base. But it’s theory time.

So, we do this, to a hypothetical green bug bastard

For fun let’s say, hypothetically again, like the hardy earth roach, he blood clots quickly.

Well, first and foremost, that higher up nervous system blackout is probably going to cue the PAK in to begin the following protocol:

1. Activate an emergency response to quickly access the situation.

2. Immediately scurry the body the hell away from whatever manner of threat just shaved a little too much off the top, engaging in all possible defensive measures if necessary.

3. Devote the entirety of its remaining backup power (of which it would have much more stored within the headless body than if it were itself detached) into making a beeline for the coordinates of the nearest Irken source of assistance. On the homeworld, or any fully colonized planet, this would be a cut and dry matter of finding the nearest theoretical space clinic or whatever those freaks have (maybe those dbz regeneration tanks? Idk that would be cool wouldn’t it?). For the lone invader… home base is the next best alternative, being a secured location with plenty of resources and advanced technology at the ready. I would bet my own head that situations like this are a huge highlight to the prime value of a personal SIR companion.

Now, best case scenario for what this help looks like depends on whether we can save and bring the head along too. Reattachment and repair at that point should be a pretty simple matter at the tech level we are working with, afterall. But that’s again, the ideal case scenario. Could they just… regrow the head eventually? We don’t really have a clear answer on what the limits and capabilities of what the Irken healing factor is, but I want to at least guess that having a personal lab and assistant on hand is going to help. Bare minimum, a solution can get worked out to supply the body with needed blood sugars again to buy more time.

The PAK itself retains a pretty much perfect digital backup of its body’s memories, experiences, and identity, so it’s not like information has been permanently been lost with primary brain damage. Replacing the primary brain entirely might be as easy as backing up your iPhone and downloading everything into some shiny new hardware. Hell, it may not even need be Irken hardware!

Do you know the real disturbing things from “Dark Harvest” NOBODY brings up are???

Why the fuck was an instantaneous organ-swapping device already just something Zim was carrying around in his toolset?

And

Zim’s morphology was horrifically receptive to those dozens of xenographs.

Those human organs were actually beating, pulsing, absolutely redundant and unnecessary in his body, but completely still functional and healthy in the name of selling his act to the school nurse. He didn’t just clumsily cram a bunch of offal into himself, he competently integrated them into his biology and somehow wasn’t suffering like… the tons of complications you’d expect from trying a stunt like that.

And in the comics, there’s this other fella I just adore for how skrangly he looks, and believe it or not, his actual fucking name is Skrang.

He’s a smart guy, though. Don’t be fooled. And I mean like, a smart guy. And it’s all thanks to a little help from a little upgrade he’s been fitted with :)

So, I hope you take all the implications I’ve been building here and make what you will of them. I genuinely think an Irken has a decent chance of making it out of a beheading alive to seek sadistic vengeance another day. Do I think ZIM could do such a thing? Tbh, I think he’d have to rely on GIR to come in clutch, and we may know that’s a complete roll of the dice in any case.

Wow, this got morbid, but, par for the course really.

This Single Oversight Will Bring Irken-Kind to Its Knees

I have a little riddle for you.

What does an ant nest, a computer, and the ancient city of Troy have in common?

While you ponder the significance of this question and consider your answer, there’s a few things I want to analyze about the worldbuilding of Invader Zim.

We may have heard it said before, least I have (and agree), that the fate of the IZ universe appears to be a rather bleak picture.

Through our lens of focus, being upon Earth and an oh-so specific nutball waging his battle upon humanity, we often don’t do as much thinking about the larger cosmic war taking place meanwhile. Not between the Meekrob and Tenn, not between the Tallest and every dumb luck threat they are thrown against, but between the Irken Armada and all life in the entire universe, sentient or not.

Their intentions will not be made any more clear, between outright eradication or eventual enslavement of every lifeform they set their sights on. While they have alliances and neutral treaties, those agreements seem few and far between, as well as born from temporary conveniences. The cards have already been dealt, and all available evidence has indicated that every planet they are aware of is doomed from the moment The Massive was operational.

Though littered with inefficiencies and incompetency that could suggest an empire in internal decline, the development of the control brains and other centralized command crutches of the species suggests the Irkens can still keep a well oiled machine running, no matter how many mishaps happen along the way. At least, that machine and their plundered resources will definitely outlast the survival of their enemies, for sure.

To speak of their enemies, there has not been a single competitive race within the show that demonstrates any credible threat to Operation Impending Doom II- only those that can resist the conquest a little bit longer than others, or those who survive by appeasing Irk (or evading its detection). The fall of Vort, which stood as the homeworld of the only aliens with the technological ability to match the armada’s firepower is…. Really bad news. That’s to say the least of comparatively primitive, TINY planets like Earth or Blorch, standing zero chance in the way of what’s eventually coming. This is a war that has continued despite the death of two.. FOUR Almighty Tallests if you follow the movie’s events… and Irkens wholly are still thriving for it across the Galaxy.

So, given all of these facts, and the perception that the Irkens (like any invasive species or colonial force) don’t seem to be a society that will make responsible and/or sustainable use of their ill-gotten territory… it seems like this is how life across the universe ends in Invader Zim one day: Not with a bang, not with the whimper of heat death, but through screams muffled under the bloody boots of a dominant predator- a predator that is, itself, doomed to cannibalize its own once it hits the carrying capacity of all existence.

Bleak, concrete, and horrific as that may sound, there’s still a “however” here to consider!

Yep, that’s me about to point one of my big fat fingers to the sky and protest- Irk just might be,

Not so Undefeatable, after all!

And not only have I figured out exactly what sort of countermeasure you need to destroy these invaders, I have reason to suspect it’s a plan already long ago set into motion.

Let’s break it down,

An Irksome Achilles’ Heel

True, individually, the bug bastards are irritatingly tough to kill through conventional means. True, collectively, they are nigh impossible to outmatch. And more than most anything else, they owe this tenacity to two things: numbers, and R&D. Possessing some of most state of the art pinnacles in transportation, communications, and military equipment, the Armada found a knack for being able to steamroll most lesser planets before it.

The genius of the individual PAK unit grants each and any one Irken a theoretical path to partial immortality itself, by route of consciousness archiving. I strongly believe that kind of cybernetic progress was also one of the stepping stones that led to the creation of the Control Brains. Nonetheless, this very same strength of the Irkens’ has also proven to be the source of their greatest vulnerability.

Paks, Paks… Oh Paks. The entire race’s civilization revolves around such technology the way we do around our own brains, our own hearts, and our communicative network. For all intents and purposes, and as I’ve gone on about ad nauseum in my other spills about the show, a PAK is all and at once

• Synonymous with the holder of their soul, consciousness, being, whatever you want to call their personhood.

• Able to have their data repurposed by future generations, in the result of an Irken’s permanent death.

• A universal necessity shared by the entire population.

• Susceptible to alterations, sometimes by intelligent enough individuals (as demonstrated by the Zimvoid comic arc), but usually by a Control Brain, directly.

In addition to that last quality, there’s another way the code in a PAK can be changed, for better or worse- Via evolution. Though I am talking about digitized neurology, the actual data in a PAK is a lot more comparable to biological DNA or a “self-learning” AI than it is a rigid computer program. By this, I mean that its code is subject to certain changes over time, perhaps both directed and completely random, particularly during the recycling of its information back into the Smeeteries.

And this is actually good design on the control brains’ part, the same way not reproducing Irkens as genetically identical clones was. Genetic and digital diversity are desirable goals to keep in mind if you want a healthy and versatile stock of workers, engineers, soldiers, and everything in between. We’re talking about highly sentient, highly intelligent, and emotional organisms here. A static drone mindset is going to offer them inadequate ability to adapt to their lengthy life experiences or be unique persons. How else would social mobility have purpose in their world? How else could the cream of the crop rise so far above their peers? That positive was deemed worthy of an obvious risk, however: computational errors.

When the Bugs Get Bugs

 IZ does not clearly lay out what it means for an Irken to be defective, but it gives us a general idea. Defectiveness is not something diagnosed from a code scan for this missing value or that incorrect variable. It’s not judged by one specific character trait or quality that’s abnormal for an Irken to display. “Defective” is a judgement stamp, wielded by the Control Brains when they gauge the total sum value of a life’s contribution to the species. And it’s not one given to Irkens which are merely incompetent, no. Anyone proven to be unfit for their standing is given generous opportunity for redemption or simply reassigned a more suitable occupation. If it were based on likability, we’d have seen Skoodge sent to Judgementia years ago.

Rather, it’s given to those who are viewed as so twisted that they are proven to be an existential danger to their brethren. Irkens that are so destructive to the essence of the collective that their memory must be purged from the record and their identity erased.

I adore the enthusiasm behind fans who want to view this as an analogy for disability or neurodivergence against a conformist society, but the metaphor I’m seeing is one of extreme antisocial behavior. A defective Irken screams less “adhd/autism” to me than they do serial murderers (of their own) or outright traitors. Pardon the use of a gross phrase, but it’d seem we were talking about an Irken equivalent of what the outdated gens would have dubbed the “criminally insane”. No one on screen has ever shown Skoodge or Tak the sort of concern that would get them sent to the Spike of Judgement, but when Zim was in that hot seat? NO one was doubting what his verdict would be.

^ courtesy of “The Trial’s” transcript

I think about the 40 shmillion mistakes a lot.

It’s such a vague quantity. But it sure sounds like a hell of a big one. And what mistakes… what did the lil squirt even have to compare them to? There’s no standard one person an Irken can be. Every presentation of the flaws in that code to the control brains hasn’t ended up a flaw to him.

I only started writing this because I really couldn’t stop thinking about the 40 shmillion. There’s no chronological room for bad self-modding to add up to that so quickly.  DNA replication, nature’s own sloppy and random process of creating new life, can be excused around 120,000 hiccups when duplicating with a 6 billion pair-long protein. But this kind of shuffling is under a futuristic AI’s precise eye. Yes, defects happen, but as bad as him? From birth??? How could you possibly get that many detrimental deviations from the mechanical fucking god-queen(s) of their entire homeworld?

And then it hit me.

You don’t. Not from Irk.

The hot take I’ve been charging for this entire time is thus.

Zim is not defective by any random accident. In fact, I smell the tampering of foreign sabotage.

Not only is this guy the thing his kind fears more than any else, they have every right to be shaking in their stance.

That puzzle i posed at the beginning of this journey, have you seen what I’ve seen yet?

Because the answer I was looking for as to what similarity connects an anthill, a PC, and a city from Greek legend was a most effective tactic for taking them down.

Do you know the best way to deal with a bad ant infestation? Cuz you can lay down all the raid and crushing action you want, but you won’t really be getting anywhere unless you target the pests directly at their queen. To that end, liquid ant baits are marvelous inventions- a sweet substance hiding a small amount of slow acting poison. Poison to be peacefully delivered by the stomach of an ant to the rest of her colony, poisoning her kin, who sicken more members, on and on until the queen is destroyed and the entire nest perishes. An insidious toxin to do all the work while its user never lifts a finger, pretty ingenious.

And when it comes to computers, we also have ways to attack entire networks at source, from quietly and far away. “Trojan” was a category of malware responsible for 64.31% of all cyber attacks on Windows systems in 2022, and they still make up a majority of active malware hits today. The concept is deviously simple. The malicious code is hidden within an innocent looking program, maybe even within a legitimate software that does what it’s supposed to. Once the stowaway is invited into the system, it can get down to it some sneaky, nasty, destructive work on your device. As for what those acts could look like, well, malware exists to do all kinds of things. Mostly something involving trying to get money/information from you or hijacking your computer for whatever its creator wants to use it for. And some of them will just up and wreck your shit, disable your antivirus software to open you up to more infections, disable important operations, wipe your data. Use your imagination.

And as for Troy.. well, where do you think Trojan programs got their name? ¯\_(ツ)_/¯

So, Irkens have their Armada, bionic drones, and homeworld- in other words, the thriving swarm of army ants, the billions to trillions of computers they so rely on, and their nigh untouchable fortress, always at war.

And some damn crafty bastard(s) in the stars said

“Here is their sugar-bait,”

“Here is their cyber attack,”

“Here is their wooden horse.”

And one particular race is going to be getting the last laugh before long.

Nerds That Are GOATed With the Sauce

That’s right, I thought about this all the way through to finding our prime suspect. And let me tell you, NO ONE in the Galaxy reeked of fish like the Vortians did. Get over here and lemme show you my whiteboard with all the red circles and polaroids on it.

- The Means

In a way of tragic irony, Vort has contributed more than any else to the same Irken conquest that turned on them in the end. A natural talent for cutting edge engineering and technical development actually does not seem to be what Irk already came into the ring with. For how mighty and superior they view themselves, the greatest achievements of their military can actually be owed to Vortian outsourcing. When we would have gotten a look at Tallest Miyuki’s very own “finest minds” during her reign, notice something interesting about these guys below,

Zim there is the ONLY Irken to be found! Yes, transferred there because of the punchline explanation of ‘he breaks everything he touches so maybe he’ll have an affinity for weapons research’ but damn right he actually did! And still does; I don’t want it to go unsaid that Zim has shown MUCH more technological skill and innovation than near any other Irken we’ve seen.

Another fun thing to note about this is that Lard Nar was also part of this lineup, and in the transcript he was in the process of working on the blueprints for The Massive. (which leaves you with the cursed knowledge that Zim, Prisoner 777, and Lard were all familiar coworkers long before the events of the show) And that brings me back to what I’m saying about the real reason the Vort natives were enslaved and imprisoned instead of outright sweeped after conquering. The Armada needs their skills, because Vortian advancement is something their own scientists couldn’t come close to. Left to their own devices, Vort could have easily outmatched them at an earlier point in history. It’s a people that figured out infinite power sources and potentially wormhole technology, while PAKs were something a disfigured human tween with a lot of time on his hands was able to crack. If anyone could outpace and outsmart the defensive measures of the Control Brains, it’s going to be them. And what better, cleaner way to sabotage the enemy than from within. 

The very same strings of inserted code that cursed Zim with his delusions, paranoia, lust for destruction, and horrible tactics may also have blessed him with a determination and intellect higher than almost any creature alive. The saboteur gave Irk the most powerful racecar in history, and then fitted it with bicycle brakes. No matter how hard Zim tries to conform to what will give him admiration, no matter how competent he is at keeping himself alive, it’s as if he is instinctually compelled toward whatever actions will cause the MOST damage to his allies in the process. Dib may think he’s the bulwark against the invasion when, ironically, he’s fighting against the one being that’s predetermined to be the arrow that strikes Irken leadership right in their dumb, green heels. (There is also an instance in the comics where Dib figures out that Zim is the ace in the hole for total Irken eradication but that’s another fun story.)

Oh, oh HO HO, and that’s only what he’s capable of doing before the empire’s actual immune system against defects like him wakes up and notices!

Three planetary blackouts, two dead generals, and a whole swath of dead invaders was just the fucking warm up, babey! All that is merely the kind of loud disruption that you need in order to fulfil the real thing this Trojan horse exists for in the first place.

What a celebration of hubris the Spike of Judgement was. Yeah, let’s take our method of filtering the corrupted data from the hive mind, and completely centralize it on a single planet! As well, let’s have the very purging agents also be the same ones to perform the evaluations themselves, I’m sure that it would be unthinkable for any outsider to design a worm that could make it through the brains’ firewalls. Goddamn spectacular. Like inserting an infected USB into your laptop, the Tallest never realized what kind of beast they woke up by plugging that PAK into the Spike’s mainframes. Those brains were meant to handle an expected spectrum of deviation when it came to defective Irkens, never a sleeper virus of this complexity.

From here it probably won’t even matter if Zim survives much longer on Earth, his virus has already spread to the very thing relied upon to keep things like him out of the data pool in the first place. With the Judgementia brains corrupted and no higher authority to overrule them, the firewall is effectively broken, and you know what that means? Bigger cracks for future defectives to start trickling through, both spontaneous and artificial. The ideal scenario is one where a degenerating and glitched population accelerates the incompetency of the empire to the point where it just implodes on itself; nevertheless, even a disease that only slows down Operation Doom could be a game changer, by giving the rest of the little guys more time to band together a coalition strong enough to strike back when the time is right.

- The Motive

The history of these two races’ alliance is something I lament us not having more lore to pull from- how far back it goes, what the character of the Vort was like during that time, what the Irkens had offered in return- a few among dozens of questions it rears.  The implication behind how it ended lies in Zim’s creation that slayed Tallest Miyuki. Interestingly, the Empire never received the memo of what exactly went down, or, perhaps, stubbornly denied the account of the other scientists who were there that day. Neither Red/Purple nor the Judgmentia Brains had any idea that Zim’s actions led to the death of a Tallest. So, makes sense that the Vortians became the unintentional scapegoat (no pun intended) for the incident, and the rest is history.

Note: It’s also in the realm of possibility that Vort was actually the one to withdraw from the alliance instead, given that the same blob that devoured Miyuki (purely the fault of their Irken transfer) also went on to cause untold amounts of devastation. Red’s reaction to the real story stuck out to me as more telling, although.

But why am I even talking about this? Zim was decades old before war was declared on them, and either people’s regard to each other seemed strangely… respectful, if anything.

But, was Vort really a monolithic bunch? Irk was already an empire by this point, and diplomacy with those they needed something from did not mean they weren’t otherwise an aggressive force in the universe. For all we know, the alliance itself might have been coerced, or result of depraved leadership among the Vortians.  Any citizen with a conscience who could see the writing on the walls would be disgusted by giving so much aid and brown nosing to such a menace, no? I know who would have seen that writing before anyone else. Brainiacs who are smart enough to build something like The Massive and all its bells and whistles would know better than anyone just what it was all capable of in the wrong hands. The collateral damage against your own people might be a sacrifice worth making in the face of the alternative.

- The Oppurtunity

So.. that’s all well and good, yeah? A why, and a what, yet this is actually the tricky part of saving the galaxy,

Sneaking your StupidifyIrk.exe file onto the assholes’ homeworld without alerting either them or your own treacherous, weak, collaborator superiors to your actions. Infecting and releasing a random Irken alive would be far too dangerous, far too noticeable to the point where they could just be destroyed outright before given a chance to wreak real havoc.

But what about releasing a dead Irken? 🤔

PAKs are only screened for criminal flaws when errors begin to affect their body’s behaviors in destructive ways. A fully competent scientist, or soldier, or navigator performing a lifetime of loyal service to the empire and then meeting an unfortunate end? Their minds’ shadows can be accepted back into the data pool no questions asked. That’s only business as usual.

That almost makes new smeets something of a reincarnation of their ancestors. Personally, I see it kind of like replaying a video game and re-rolling your stats, even if you’re reusing your character’s name and general play style.

Either way, we come full circle to my theory about Zim’s actual origin. Maybe not “our” Zim, but the previous iteration of data that was shuffled to create his person. Whoever they were, I’m convinced that they were also an exceptional individual. They were probably pretty arrogant, but it was a more earned confidence, and they were a prodigy genius, the likes of which that was drawn to work alongside Vortian allies, as another researcher. Then, an untimely demise befell them. I couldn’t say they fell victim to some unfortunate accident, considering the cockroach durability of their body. No, I find it a lot easier to imagine they met their end in one of the more embarrassing ways for an Irken to die- A PAK stolen, disabled or forcefully detached by an assailant they might have allowed a little closer than they should have. To the homeworld, it’s a small matter. One more PAK recovered by the natives of the friendly planet, brought back home to be repurposed by the smeeteries, right?

Well, that’s what one smartass might have been hoping for.

And they really were a clever cookie, because that scheming seed is fruiting beautifully.

You know, first time watching this episode/series you think this move is about devotion to the cause/loyalty to the empire before you understand what a remorseless narcissist Zim actually is.

So now I’m raising an eyebrow at this because if he was SO ready to reach for that button at the first risk of being outed, uh,

What usually happens to other Irken Invaders in the event of the natives sniffing them out?

Or more specifically, now that I think about how Operation Doom II was still in the earliest stage, what were Irken soldiers being taught would happen to them if they were captured by another species?

Skoodge has been excluded in the name of actually underrated characters. Had the series not been canceled, he was already on schedule to join the main cast on Earth anyway.

Tak was never officially an invader to begin with.

And Tenn’s unfortunately failed in her mission, as far as implications go.

Obsessed with this little gag in “Backseat Drivers From Beyond the Stars” when, as the Resisty approach The Massive, the Tallest drop the donuts they were excitedly mowing though beforehand.

And then after like one second of pause, all of the navigators on the bridge (who, mind you, are almost always portrayed as some of the most mature and rational irkens of the whole species) all freaking swarm forward and start fighting each other for those pastries like a pack of starving rats.

The way they all begin the shot not even doing their jobs, too. Just gathered up to watch Red and Purple eat those donuts and quietly pray for scraps like this lmfao. I assume away from post just because the Massive was parked for a break. AND the fact that not one of them hesitates for even a second before basically stealing food from their distracted, but still almighty leaders. Either those were just some particularly good donuts, or Irkens act like greedy cat/dogs whenever they get the chance around someone who currently has food they don’t.

Who are your favorite irkens in invader Zim?

Precious anon, this is like walking up to me pigging out on a box of oreos, and asking me which individual cookie is my favorite in the package. The answer is probably “the one I’m currently eating!” with a dumb, cockeyed grin before I turn and reach for the milk.

So thank god you gave me a plural option. If you didn’t, I’d find it challenging to not say Zim himself. Series protagonist, an absolute riot, complex, and, well, it’s hard not to absolutely adore the vibrance Richard Horvitz’s voicework breathed into him.

Skoodge, on the other hand, is one of the characters most of all I have long wanted to see more official content of, most especially even though impossibly in the TV show. He’s usually the one I’ve cited as my favorite Irken over the years. He’s relatable, hilarious, endearing, repulsive, somehow inspiring, but most of all extremely interesting for how unique of an outlier he is in the show when he’s not being the universe’s preferred butt-monkey. Ted Raimi made him pretty easy and fun to listen to, and he has this history and dynamic with Zim incomparable to any other character in the franchise that just... it had so much potential that nickelodeon really slept on. I’m fairly certain I even heard Vasquez complain a bit in a dvd commentary about how underutilized Skoodge went when the series was cancelled. There were serious plans to involve him more as part of the actual main Earth cast and a couple of the unfinished scripts incorporate that, and I’m always one to recommend them. Not even to mention that there was a pitch in the works for an episode where he and Tak would both get screen time.

And speaking of Tak, she’s up there as well, as cliché as it might be in this fandom. The Dibship is nice to have and all, but it just doesn’t scratch that same spot her flash in the pan performance did. Goes without saying she had incredible value as a recurring foil to zim, and like skoodge, she stands far apart from other Irkens in a way that gives her so much more personality for it.

The current tallest, of course, but definitely Red a deal more than Purple. Out of all Tallest we know of? Miyuki, hands down.

If Zib counts, he deserves mention, for no other cause than the fact that he’s kind of the entire reason I got back into invader zim to the point of it over taking so much of my blog activity. That’s not even an exaggeration much, the brainrot started anew with finding out about him. The horrid thing.

Tenn and Larb purely for their proximity to major parts of the series’ world building. Gashloog has a funny name and reminds me a lot of when I used to work in food service myself.

If I could only pick one Irken to kidnap from the horrors of Jhonen’s writing and provide a good home to? Table-headed service drone Bob, any day.

Endearing through the Alien Lens: A Clue About the Primitive Irken?

I love literary xenobiology. I love it a whole lot, in fact. There’s a paradoxical line I dance across, between criticizing intelligent fictional aliens for their likeness to our species, and criticizing them for their unlikeness. It’s a pretentious and laughable dance between “Come on, the sky’s the limit, there’s no real reason for a bucket of different extraterrestrial races to just all be more flavors of quirky humanoids! Boring, show me something actually alien!!” and the yearn for the use of alien races as a funhouse mirror of mankind’s own evolution. I think the way Irkens nonchalantly dwell somewhere on that subjective tightrope is a good part of why I can’t seem to stop thinking about them.

They are inspired and yet creatively original. They are truly alien, and yet, they can still play foil to the bottomlessly decadent humanity that Vasquez’s Earth has set the stage for.

Before, in the very first brain dump I let loose about them, I noted a few of their parallels to the worst in Homo sapiens and the insects they resemble. This time, something is chewing on me that i haven’t seen another put into perspective. A something that seems contradictory to our collective view of the heartless, sexless, atomized conquerors that all of the cosmos will fear:

They… have parental instincts.

I didn’t necessarily say drives or wants; however, they undeniably havewhat seems to be an actual, instinctual “cuteness response”. Like us, like social pack animals which invest a great deal of resources and time into their young. Given that the closest thing that 100% of smeets born on the home world get to call a parental figure is a literal cold, unfeeling, automated machine, this seems kind of weird, doesn’t it? They’re not even born like mammals or nested like birds, they’re mass produced, like hived wasps or ants, miles beneath their actual society and out of the business of the adults. So, what the heck with them being written to be humanized with this baseless, arbitrary trait?

But, ah ah ah, nitpicker Scarlet, it’s not baseless. It’s only ✨vestigial✨

Y’all could probably make a good guess to what the cuteness response is and why it exists in Homo sapiens, but to sum up- it’s the phenomenon of when we see something we find “cute” and it makes us react to it in a protective, nurturing fashion- or also want to bite/squeeze things, weirdly, if it’s just too damn cute. Well, what do humans find cute? Things that resemble human infants, basically. It’s a biological reflex that makes us want to defend and provide care for our kind’s absurdly dependent and slow-developing young, rather than abandon them in the shrubbery like they’re just screamy, food-leeching paperweights.

“Pff, really? Well I must be special cause I don’t even LIKE babies. I think babies are icky gross, not cute! So, genetic instinct my ass!”

I hear you, sure, but what about… harp seals? Or koalas, or pandas and puppies and fawns and kittens? Or funny little cartoon blorbos? At bare minimum you’d have to be an alien yourself to feel nothing looking at photos of young hedgehogs

See, the fact that a lot of us may often find baby animals a great amount more endearing than even humans’ is not even in conflict with this understanding of cuteness.

The concept of the “baby schema” was formally proposed in 1943 by Konrad Lorenz, an Austrian ethologist. Fun fact is he was also the same researcher who originally observed and described imprinting behaviors, as seen in newly hatched waterfowl. Point is that his “Kindchenschema” idea grouped together a handful of infantile traits that make fireworks go off in the parts of your brain that wants to keep things alive and baby-talk to them. Included on the list were features like proportionally large heads, big eyes, round faces, short noses, etc. despite the name, the baby schema’s effect is something applied not to just actual babies, but children generally, and even in our reactions to non-human animals.

It’s the hypothesis behind both why we’ve jacked up the skulls of so many small dog breeds in the name of aesthetics and why we generally find the portraits on the left side of this image more appealing to look at than the ones on the right.

The consistency of these features across many species may also give some hint that they experience a similar phenonemon, especially given that these are traits shared among bird or mammalian offspring which require significant attention and protection to survive. And, it may also explain why this image likewise gives me a huge dose of that sweet, sweet response.

Awww, look at that lil’ mans! Look at his teeny noodle arms!! I just wanna pinch him like a marshmallow!

YOU are not immune to cuteness psychology, and neither are the proud Irken warriors. I’m going to cite Zim’s proclivity to what I can only describe as paternal bonding as a demonstration of this response, but before you go reminding me about his pak defects, it’s far from the only evidence that this is a natural Irken trait.

Check out little Timmy (importantly, the surrounding response to him), a hilariously out of place youngster who appeared briefly in the trial transcript for the sole purpose of a dark gag and to get us some lore revealed.

Take further note of the complimentary nature of smeets themselves.

Suddenly finding themselves alive, fresh Irken babies too, like the hatched gosling, begin to immediately seek an emotional attachment with the first animate thing they see. While mobile and fast learners, smeets are far from being able to truly fend for themselves. They’re tiny and naive and they need lots of mental enrichment/teaching. They also play and form something akin to friendships, much like human children. In the bygone era before Irkens were so reliant on Paks and all of the advanced technology of the modern empire, smeets would have been exceedingly vulnerable. All signs point to a phase in Irk’s natural history where they were once nurtured after by adults of their own kind, and commonly bonded with their caretakers. This could mean compact family units, or maybe even a communal raising situation, akin to penguin crèches (Personally I like to headcanon that the tallests/queens were traditionally the only breeding members of the population but that’s neither here or now). Either sense, the evolutionary remnants of a parental creature are still around.

Taking all that to note, instead of perceiving Zim as the bizarre outlier to the Irken condition when it comes to having this soft spot, I instead see him as an opportunity to see natural behaviors in action without the suppression of his militarized society and its distractions. Even someone as warped and selfish as he can be is still very, very full of love to give that he doesn’t even understand enough language to describe. He pretty clearly shows he has no cultural understanding or reference of cuteness, and still, he’s not so different in this “weakness” than the very humans he manipulated into fawning over Ultra Peepi. It just took an example his own sensibilities could relate to instead of an unfamiliar, repulsive alien rodent.

And when he’s given the rare circumstance to show that potential, well-

*(With the rough shape/size down, no nose, and huge, bug-like eyes, Li’l Meat man may actually be a great approximation of the key “smeet schema” features. More importantly, it was made to specifically resemble Zim himself)

- I feel that’s downright adorable.

Irken senses, and other ponderings

You know, every time I start to wonder if I’ve finally run out of things to coherently say on the whole “speculating about irken biology” matter, a whole something more is induced to hatch out of the dehydrated floam inside my skull. Between you and me, I think the eggs are triggered by ironic timing.

Anywho, I’ve been thinking a lot lately about the world hypothetically through Irken eyes, and other sensory organs. Think I’ll go down them piece by piece, and to follow the pattern I’ve kept through my other Irken brain dumps, I will be drawing a huge amount of inspiration from real life arthropods. Yes, I’m very aware that realistically, any resemblance to earth insects would be coincidental from an alien species, and there’s plenty of room to make up whatever somewhat plausible explanation you can for any faucet of their anatomy. Personally, I like to run from the convergent evolution angle, since I find it no less grounded, full of potential connections the show itself all but begs me to draw, and just plain fun. Let’s get into it.

Also like towards the end there’s a whole section on the hypothetical edibility of Irkens because why not

Prelude: If you want to hear a little more behind my theory about the Irken diet revolving around sugar and a small portion of minerals, you can zip onto this analysis I did, in which I touch on some ideas of mine regarding the composition of Irken skin, their reaction to meat, etc. that works from the assumption that Irkens evolved out of an arthropod-like ancestor. Not necessary to get the gist of this one, but it is background context behind my thought process.

Sight

The Irken oculus is perhaps the most striking feature of the species, very much resembling those tiny crawling things they have been inspired by; however, it’s tougher to say exactly how far the similarity of their insides go. The eyes of most arthropods are in fact along the more simple branches of the evolutionary tree. We know that Irkens are not likely to possess compound eyes, like those found in flies and most other insects, because compound eyes are specialized for wide FOV ranges at the sacrifice of visual resolution quality. Instead, I see a much closer match to a fascinating exception or two found in Earth’s arachnids.

While most of them have utterly piss-poor vision, the hunting styles of jumping spiders necessitated a great deal of further specialization of the organs for depth perception, color differentiation, and sharp images. These are the purpose of those two huge shiners at the front (the other 6 boosting their range for detecting blurry peripheral movement and threats), and these are what bring their effective vision on a level much closer to that of familiar binocular mammals than their own six legged prey. Now I really think we are working with the base of what Irken peepers likely developed out of. One of the ways they have really diverged off is in the fact that while jumping spiders can only move their retinas, irkens seem as though they are able to move the lens of the eye themselves- or at the very least, Zim does, else the false pupils in his disguise contacts would not behave quite so convincingly. To speak about the lenses themselves, their eyes are not dry and exposed like most arthropods, speaking to a vulnerable sensitivity. They clearly have blinking eyelids, shed tears, and Zim even complains about the “scratchy” feeling of getting used to that part of his kid disguise.

(Funny sidenote: I’m like 90% sure that Zim did not have those contact lenses designed correctly for himself. Usually, if contacts feel that uncomfortable and keep falling off of the eye as easily as his do, it’s a sign of them being poorly fitted. This could be another symptom of his outdated/lower quality invader tech.)

Not only do Irkens have an assumed base vision resolution that seems more or less on par with human beings, but Invader elites are fitted with ocular implants that grant them a significantly greater advantage in this realm. We don’t know to a certainty how well improved an Irken soldier’s vision is, but Zim was confidently able, within seconds and under pressure, to pick out the area of town he lived in from what was miles away under night hours.

On the topic of night vision, I have a hunch that even without the cybernetics, these guys are adapted to see much better than we in dim to dark environments as well. Most of the early part of their life cycle is lived out in subterranean crèches. On the surface, daytime Irk is cast in a sunset red atmosphere. Oddly, a massive portion of their fashion and architectural aesthetics show a preference for these dark, warmer tones. Ruby is far and away the most common eye color in their kind. All of these facts suggest that warm-spectrum hues and pigments were incredibly common in the homeworld’s history, to point of indicating something about a cultural attraction to them- kind of like how humans put the color blue all over so much corporate branding and elsewhere. Zim’s favorite color has also been revealed to be purple. Most of all, given what I’ve seen of Irk’s, Blorch’s, and Devastis’s surface skies, AND Zim’s reaction to staring directly at the sun for more than a few seconds, I’m assuming that most Irkens are wholly unfamiliar with living in an environment as brightly lit as midday Earth.

I do think Irken eyes “glow” in the dark, but not in the emitting sense. Just more in the reflective one. This they would owe to a well developed tapetum lucidum, as seen in cats and deer and pretty much any animal to give off an eerie eye shine under the right lighting. To point back to arachnids, wolf spiders are speedy nocturnal murder machines with highly developed tapetum lucida, in their secondary eyes, at least. What I love the most about that is it makes it very easy to tell if you’re looking at a mother spider because her babies will give off the same eyeshine if you take a pic of one with the flash on.

Additionally, I won’t forget that sleep is no longer a necessity for our alien subjects. This alone gives them a major edge over any dinural race such as humanity. While Zim has his appearances to keep up during the day, the nighttime on Earth is actually when he is allowed the most free rein to work on his endeavors uninterrupted.

Sound

Ah, so this is the part where I rattle off the common theories we’ve collectively formed about Irken antennae as the replacement for an external ear, eh? Yes, but actually no…. jokes aside, it’s just no. I’ll get to the deal with antennae, but as you might imagine, hearing ability also varies all over the place in the insect world.

It is true that antennae play a large role in the hearing of some critters, such as mosquitoes, whose males use them to pick out the high frequency wing beats of nearby females in a swarm. Crickets, on the other hand, use sensory organs on their legs tuned to much lower sound ranges. There’s no one way to evolutionarily put together a sort-of ear, as well proven by the sheer amount of times it convergently happened in bugs and in how many creative ways.

They literally be designing themselves like me playing around in spore. If we’re not talking about that mosquito or honeybee example, then what we are referring to as an ear and most hearing insects is going to be an external tympanic organ. Most people who have passed high school biology would be able to recognize a visible tympanum in frogs- that circular thing right behind the eyes in most species, and understand it as their version of an ear drum. Many bugs’ tympanums are likewise thin chitinous membranes situated… potentially just about anywhere on the body (again, see above). This is what I think Irkens use as a primary hearing organ, in his case, probably situated on their heads in addition to the feelers. The latter organs I think would also be sensitive to general vibrations and subtler environmental cues, like wind direction and pressure changes, but the bulk of their hearing would be owed to the tympanum.

As far as the quality of their hearing, well, there’s not any sign it differs much from the human experience. Like us, they communicate through verbal language, and the existence of the “Dancing Arcade Game (but for aliens)” confirms at least a similar cultural propensity for music as an entertainment form. Zim is an outlier for the fact that he seems genuinely a little hard of hearing next to his kin, screaming as naturally as he talks and repeatedly mishearing (if hearing at all) people who are speaking directly at him. It’s clear something’s up with his hearing, but there’s no clear answer what and why. At first I was tempted to suggest something about sound passing much differently through the medium of earth’s atmosphere (kind of like how noise on Mars would sound muffled to us), but neither Tak nor Skoodge seemed to pick up the problem when they arrived. It really could be as simple as some kind of birth defect, or even glitches in how his corrupted PAK is processing the inputs it receives. Like many others, I want to imagine that his wig could be interfering too, since it covers the whole top portion of his head; as well, I noticed he has more of those incidents with it on than not.

Smell

Alrighty, NOW we can round back to focusing on the antennae, because this is actually the main thing our insects fine tuned theirs for. And when I say fine tuned- I mean fine tuned. Blood suckers that find their prey through the CO2 of their breath, flies that can pick up on potential food sources from miles away; In the land of the little, scent is everything. Beyond it being their main tool for exploring the environment for what to eat and what to avoid, chemical messages are the backbone of bug-to-bug communication. Pheromones are the divining rod of lonely spiders looking for a mate. They are the bugle of yellow jackets when rallying the nest to attack a threat, and they are the signals that govern about every single action an ant takes from adulthood until death. Obviously, Irkens are much more sight & hearing dependent than these comparisons, but they still have much more bodily specialization dedicated to this sense than we can relate to. For one, they are fastidiously hygienic. Like, “the care-bots from that really creepy episode of the Buzz lightyear cartoon” hygienic. We have yet to see any livable surface of Irk that is not sky to underground terraformed over in all-consuming metal infrastructure. There’s less than no sign of visible life besides the Irkens; ffs, there’s not even soil in sight. Not on Devastis, either. The Organic Sweep sounds like such a nice and pretty euphemism in the face of the actual horror of Blorch’s fate, and all to spare the boots of their military from touching even a speck of “unsavory alien filth”. They live in such a controlled and purified environment that I can’t even imagine the absolute assault on the senses Zim’s every day on our barbaric ball of dirt is. Over and over again he gives off the impression that the constant stink of this place is in fact his chief complaint about living among us. The majority of insults he throws toward humans relate to how they smell or the fact that he finds them “filthy”. We’re flat out nasty to him and I don’t blame him. Even relative to other animals, humans are especially RANK due to the combination of sweat, oils, and bacteria that coat our skin.

And believe it or not, I do think Irkens are in a position to talk shit in this regard. Zim is a really sweaty boi; however, I posed an idea back in that write up about Irken skin before- to summarize- that his kind maintain remarkably sterile cuticles due to the presence of a toxic chemical in their skin. This, I said then, could have been the key to Zim’s lice repelling trait, but I wasn’t so specific at the time about more than that. I got the idea from a group of millipedes that, when disturbed, can secrete hydrogen cyanide as a deterrent to predators. I like to imagine that Irkens can do a similar thing via sweating, not to thermoregulate like us, but as a stress response. It would at least explain why Zim seems like a very nervous sweater. Fun fact if you didn’t know, cyanide’s smell is similar to almonds.

I’m deadass telling you I think Irkens just smell like almond extract. Do with that what you will.

Touch

So, in writing this whole whatever it be, this part was the trickiest to come up with any productive analysis on. I’ve already guessed at what I think Irken skin feels most like (spoiler: hairless caterpillars) in the analysis I referenced up top. Zim being able to pass himself off as a human under the examination of the Skool nurse points to an average body temperature somewhere around our own. What I did find interesting while rewatching the series though was the sheer amount of pain tolerance on these invaders, except in one way. Can I extrapolate this fortitude to Irkens universally? Probably not! Zim is a member of the most elite of the most highly trained members of Irk’s military. I wouldn’t take what a seasoned veteran can handle and assume that’s the human floor in a nutshell, but our invaders CAN tell us quite a bit about their ceiling… starting with the fact that these bastards are ridiculously heat resistant. Irkens are a durable race broadly, but their reactions to extreme temperatures strike me as jaw-droppingly underwhelming, if anything.

Irkens DON’T like being engulfed in flames. It’s still a painful experience to them, but seemingly the kind they can pretty much walk off as soon as it’s over. Through explosions and fire we have seen Zim (and Skoodge) survive in one piece. We’ve seen The Massive take a whole dip into a burning star with no ill effects to the crew within. Most amazing to me was the time in Battle of the Planets when Zim willingly piloted Mars into grazing by the Sun at close range while trying to evade Dib. Totally exposed driver’s seat and he was no worse for wear after this.

Further in the comics we see this touched on in the Zimvoid arc. Zib’s favorite method of torturing the Zims under his training program was to torch them at random for sadistic amusement. Quite interestingly, though, Number 2 implies that their bodies do actually adapt to this treatment over time! Theoretically, Zims further along in the program have become all but invulnerable to fire entirely.

On the other hand, one of the truly most painful things Zim has been shown to experience is to have his skin chemically burned. It’s a strange sort of irony that Earth’s water would prove to be an incapacitating force to them in place of any inferno. He’ll smash his skull into the Voot’s windshield with enough force to pop out an eyeball and it’s whatever. Plenty of other things hurt, but he can power through. You turn a shaken can of soda or a bottle of bbq sauce on him and he’s just left screaming on the ground or screaming and running away. Whatever brutal sort of training he had to go through off world, it didn’t prepare him for this.

Taste

The perceptive side of this I think may not be too hard to figure out. Irken food, as alien as its actual composition could be, has been shown to be heavily analogous to human junk food. I hesitate to call what Irkens are scarfing down “meals” in the proper sense, because I’ve noticed that neither Zim nor his kin intrinsically understand the concept. When he’s trying to blend in as a human being, he puts a LOT of bizarre effort into convincing us that he, just like you inferior creatures, TOTALLY eats “food” on a regular basis like a normal person. When Irkens eat their own products, it’s all and only “snacks”. What follows is the conclusion that their eating habits are not structured into any schedule and that Irkens instead graze throughout the day as they please- and even possibly that eating altogether is more a recreation to them, instead of a necessary function to sustain life. Some fans have speculated that the PAK could provide an Irken with all of the necessary energy to survive absent of nutrition. I kind of want to contest this, given that caloric energy is only one purpose of taking in food… but it’s definitely the most immediate one. Nonetheless, they still eat constantly on screen and it all has to be going somewhere. Whether they need it or not, they still readily digest snacks (and presumably use those chemical building blocks to regenerate tissue damage) with a terrifying metabolic efficiency. Assuming that the resemblance of their snack foods and our leisure treats are not purely coincidental, one gathers that sweetness is the largest dimension of Irken cuisine. They are drawn most enthusiastically to carb-dense synthetic, plant, and possibly fungal matter in the same way that the human brain lights up at the prospect of fat and sugar-loaded meals. The flexible tongues of Irkens to me also resemble the nectar catching, segmented mouthparts of some bees. I would be willing to bet that they can taste salt, but jury’s out if it is something they crave, like us, or are repulsed by, like ants. That would have to come down to the scarcity (or not) of the resource on their home planet and whether or not desiccation was a serious threat in their natural history. In other regards, Zim shows strong negative reactions to most Earth foods, if not physically, than in his expressions. They definitely have powerful vulnerabilities to many human ingredients, and so are very sensitive to the presence of these toxins. I can’t imagine acidic or bitter substances are at all pleasant to them.

Now comes the much more interesting question I’ve thought way too long and hard about in the shower a time or two. Knowing that Irkens are likely a herbivorous breed, ergo, thankfully would have no interest in the consumption of the human race… what about the vise versa??? I don’t just want to know what they taste, but what would they taste like?

So, you’ve decided to mix it up for the thanksgiving dinner and forgo the same boring old bird for an Irken you have vanquished (via what I can only imagine was a freaking miracle of luck). What should you come to expect? Most importantly and I must emphasize this, the secret to preparing their meat is the same as Tolkien dwarves, you have to skin them before anything else. The separation of edible tissues from the cuticle is necessary to avoid ingesting the defensive toxins it contains. Even if the concentration is not enough to provide a danger to you, it could end up contributing an unpleasant, bitter flavor to the final product.

That done, discard the head and digestive organs. True as it may be that Irkens are wholly free of parasites, with a chance that the viscera could be edible, it’s not likely to taste that great and besides, do you really want to take chances with exposing yourself to an entirely foreign gut biome you have no immune adaptations to? And don’t even think about the brain- I don’t care how rare the infection rates are, alien prions are a big no. If you happen to run into any cybernetic implants during the cleaning, however, set them aside! They could be worth a small fortune in the right circles. But, for the purpose of eating we’re really concerned with the muscle tissues, a delicate white meat with a texture similar to fresh crab. The bones need not be wasted, and are fine to leave in, or can be boiled on their own to make a flavorful stock which can be added to soups or a delightful gravy. A surprisingly practical use of Irken bone could also be in the compost bin, being rich in chitosan and other powerful garden fertilizers. The flesh can do well fried, or roasted to a crispy exterior. The oven rule is the same as chicken, low and slow, to prevent drying out. Don’t be afraid to experiment with the gravy idea or marinades. The flavor profile of the meat itself would be utterly unique from what most of us are used to, comparable to a nutty crayfish. Savory, a bit of a sweetness, and a mineral hint that pairs quite well with mushrooms or rice.

I can’t recommend serving this to any guests with shellfish allergies in good conscience. If they insist, do so in caution and with knowledge of the risk of cross reactivity.

And there you have …. certainly a thing I did write and queue up for y’all!

IMO the show seems to indicate that Irkens actually live within accommodations at their occupation site. Zim was an actual prisoner of Shloogorgh's Flavor Monster, but Sizz Lorr is implied to be living there too, considering that he has everything packed with him to announce that he’s going on vacation. Irkens plan out their infrastructure in these extremely travel inefficient ways, like “one type of district per planet” inefficient, so it would make sense that changing jobs can quite literally mean a planetary relocation OR even living your life on a specialized ship that is constantly moving from place to place (think Tak’s janitorial squadron or The Massive’s Crew).

Not having any need for sleep, I would guess that Irken businesses are run constantly with rotating shifts if they have enough staff on hand. Their stamina isn’t exactly endless, and workers with no free time are not great consumers, so Irken working standards actually don’t seem to be as droning for regular employees, provided their supervisor is not a huge jerk. Of course, an unspoken amount of the intergalactic economy is also propped up on the backs of slaves too, both Irken and alien. I don’t imagine they have the same privileges to speak of.

Aside that, Vacation time and regular breaks appear to be standard, even for their frycooks, impressively. Employment seems to be designated on an applicant/hiring basis and paid for wages/salary (though forced labor is a common punishment for criminals). What’s interesting to me is that we’ve seen coin currency does exist in their society but I wanna imagine that “monies” are usually distributed as a digital credit that their PAKs keep track of, like a personal wallet. We saw Zim using his to operate a vending machine on Devastis, after all.

As for what they’re doing on their off time and with their monies, well, we actually did get to see a glimpse into that once on Foodcourtia.

Zim, presumably taking a little sit in… what I imagine is some kind of employee break room, or possibly even part of a living quarters. We know that they don’t have beds, per se, but lounging chairs and couches are common furniture where they linger. I don’t think there’s really anything they have in regards to housekeeping chores so long as it can feasibly be taken care of by machines. So, I really beleive the bulk of average Irken life is work, and then… this

And also some of this

And definitively plenty of this

Any kind of hedonistic, consumerist, instantly gratifying sort of recreation you can think of would be at their disposal. Video games, music, mindless television, cheap confectioneries, and even some degree of socializing, in their own ways. Which could all either sound utopic or dystopic, purely depending on how you frame it.

hey like actually. do u guys think irkens have like. houses. what do they like,,,,,,,,,,, do. daily. alien laundry? or are they always out and about working or doing shit beclaws they have no purredators and no need fur sleep. ive always wondered

I'm only giving people an irkiddies pass if they aren't cowards about it. This is NOT a heavily sexually dimorphic species (I mean they’re sexless to begin with in canon). Even if they used to be, their technology is well past that, they're freaking tube-grown. The line in the sand is only drawn at the most minor aesthetic differences. Either chest meats for none, or chest meats for all. If you're already out there titting up the lady invaders yet unwilling to follow through with Big Naturals Skoodge, you are weak in the mind and spirit.

efurry time someone draws an irken with boobs a fairy loses its wings

Completely tongue-in-cheek but every time someone tries to manufacture a kind of discourse-lite out of shipping Irkens with whatever other specific Irken because THEY headcanon them as siblings or similar, that one stupidass joke from the Bee Movie violently claws its way out of my memories and tells me someone needs to redraw this

“Invader Skoodge more like Invader STOOGE am I right?!”

Irken Smeet collection

From left to right:

Zim, Skoodge, Grenty, Grinn, Skutch, Purple, Red, Pint, Gooch

Literally what other Irken even does this?! Refresh my memory if I’m wrong because Irkens actually do have a working construct of morality. Like they’re not actually that far and away from human psychology at all, other than the hyper militarized, imperialistic culture. On the whole they can be a cruel and very destructive people, but out of a tribalistic belief in their united supremacy. They have empathy- selectively applied to their own kind. They have respect- conditioned to yield literally upwards the chain of command. They understand loyalty and justice and even something akin to friendship.

Yes yes Zim’s a living symptom of a very diseased system, but it always grazes me just a little wrongly at how much I see other fans blaming all Irken society for the degree of Zim’s antisocial tendencies. Every bit of cruelty and scorn they have thrown his way, he has literally been earning from them since the day of his birth without a single hint of regret or intention to stop. Sizz-Lorr and Red and Purple and Poki are not a pack of bullies to him, they’re terrified and appalled of him, and they see him as the maniacal criminal he is. Red is, for all intents and purposes, also grossly callous toward his subjects and downright tyrannical to conquered races, and even he would call zim a monster for killing two previous Tallests. You’d think if he were some true purely self-interested dictator he’d maybe see the silver lining that it got him into his current position.

I don’t remotely think Zim even buys the idea much of Irken supremacy inherently, just Zim supremacy, and a little of that trickling down onto other Irkens abstractly, because they are lucky enough to the same species as ZiM. The harm he causes his brethren, though? He’s proud of it, the same as he is for acts of sadism against lesser kinds. He wants commendation just for showing off that he has the capabilities to destroy their entire way of life unchecked. He feels no remorse for the deaths of Miyuki and Spork, no shame for his devastation on their home planets. Skoodge (who I can only assume is cracked in the head for this) offers himself up to the guy as a faithful compadre again and again only for Zim to throw him to the wolves and unnecessarily endanger his life. Over and over we get shown the primary motivation behind his attempts to win the Tallests favor actually being fear of retribution from them, not any ernest desire for redemption. I swear a time or two, the longer he is away from his society the more times he lets slip his honest regard toward the flag he flies, and Dib is blissfully not listening carefully enough.

If Skoodge or Poki or any of the others didn’t make a stark enough contrast to Zim’s chaotic evil ass, there we always have Tak. Tak who did everything right, save for ending up an unlucky collateral of this idiot’s antics. Tak who arrived determined and bitter, barely holding back righteous fury, and doing all of the things that Zim isn’t- the actual work involved with repairing her status and earning her place back in Operation Impending Doom II. Zim thoroughly screwed up this poor soldier’s career and dream and he doesn’t have so much as an excuse or apology to offer when confronted. He completely understands Tak’s vendetta against him, and he doesn’t care.

Tak herself isn’t the kind of monster he is. To humans, yes, she’s the same if not an even worse threat because of her competence; and yet, she would have been a hero to Irk if she had succeeded and gotten Zim out of the way. She presumably had the explicit clearance of the Tallests to do this, she did her due dilligence in tracking down Zim and taking over an otherwise “unclaimed” world, and she truly believes she is acting above petty revenge- she uses all the logic of fairness and the rightful way of things to justify what she’s doing. She shouldn’t even be here and she shouldn’t have to be taking someone else’s assignment. Zim is the unhinged supervillain, and she’s taking back what he in a sense stole from her. She actually wants to serve her empire to her fullest capability possible.

Zim on the other hand just wants to see the world burn. Any world… Earth, Devastis, Mars, Irk, it truly does not matter that much. The sick pride in being the one who can burn the most things is its own reward to him.

Infamy and veneration are exactly the same feedback to this guy, as long as all eyes are on him while the crowd screams.

I mean, okay, the funny thing is that it’s a very common Trope to have the Evil Villain who does a lot of Evil things but is so deluded and full of bullshit self-justification that they earnestly believe that they are Good, even as on some level they know this is wrong. It's just something they cannot admit to themselves, and this denial is a fundamental part of their psyche. And Zim Invaderzim is… not that kind of character. Zim is very proudly and shamelessly horribly evil.

But also on some level he is that Trope…. for the other axis of the D&D Alignment System. Zim is a Chaotic Evil Villain who is obsessively dedicated to maintaining the self-delusion that he is Lawful Evil. 

Lying awake at night and grinning like a cheeky imp at how ironically Powerman 5000’s “How To Be A Human” would make for an absurdly appropriate mv about Irken Society actually

Less joking/elaborated answer- personally headcanon that Irken cuticle is naturally a very hostile environment for pathogens to exist on. There’s some room to potentially argue that they have a much more alkaline surface ph than we do, and their skin was already shown to possess anti-parasitic chemical properties. I don’t think they actually use water to clean themselves because I assume their self grooming habits are mostly about exfoliation. Their skin’s more durable than it looks and regenerates super quickly.

I DO like the dust bath idea, albeit knowing how dirt-free (and dirt repulsed) modern Irken society seems to be.

My original thought, however, cause of how I got so hung up on that “cleansing chalk” quote, was something literally like the body rock. Like, pumice stones.

Cause otherwise idk who the hell uses bar soap dry in this manner, or more importantly, why the original sound effects were scratchy and rough.

how does zim bathe himself if earth's water is too dangerously polluted for him does he just import space water or something does his protective paste slathering double as cleansing does he just go around stinking all over the place that would contradict my headcanon of zim having a unique and pleasant alien aroma
