Deltarune Headcanon - Tumblr Posts

I’ve got a headcanon that there are variations to the outfits of the Deltarune characters based on the darkworld they’re in

If I feel like it, I might do one for Ralsei and/or Susie

(Close-ups under the cut)

I have this headcanon that monsters are not assigned any gender at birth, they just refer to everyone with neutral pronouns unless told otherwise by that person or someone who knows them. They may or may not have certain features most humans consider masculine/feminine, and thus some might assume a monster's gender, but monsters themselves couldn't care less about appearances. Because I think those differences don't show up until a monster hits puberty or something, and even THAT doesn't happen with every type of monster. Aaaand I also think they don’t have genitals so there is NO WAY someone could say a person is [insert binary gender here] until a certain age

But maybe it works only for undertale (y'know, because monsterkind was isolated from humanity's influence for ages), and in deltarune they have agabs. But I'd like to think they are still super supportive of trans folks. Everywhere, not just in the Hometown

LESSER DAD AND LANCER HEADCANONS~ <3

* I know this has probably been pointed out before but remember when lancer showed his "Stool forme" y'all know who else puts random e's in the end of words- Rouxls hecking kaard he taught him that. *rouxls is made out of a slime like substance. Whenever he gets nervous he  starts to melt. Literally. *Lancer sometimes picks up on some of rouxls' habits such as sometimes using old english but oftentimes doesn't know what he is saying. *One day Lancer's father (king meanie stupid bad dad) kinda got sick of Lancer being clingy all the time and Rouxls took notice and started taking up as his own responsibility to raise Lancer and care for him despite not actually being his father. *Lancer is always trying to get the approval of his father. Yet is always brushed aside. So when his father sent him out to find and fight the Lightners, he felt it was a chance to finally get the fatherly love he yearned for so long. *Rouxls never intended to get attached to Lancer. And he never intended to be seen as a father figure. Yet things happen. And thus the nickname "Lesser dad" was given. *Rouxls may not exactly like Lancer's MP4s, but he loves the happy little look on face of excitement for his own creation. Although it is not pleasing at all to his ears. *Lancer sees Rouxls as a sort of father, yet his actual father is not at all like Rouxls. Rouxls actually takes care of him, like a real dad would. Yet his real dad is nothing like a dad should be. So Rouxls to Lancer is a dad. Only less like the dad he has. A lesser dad. That's all folks! Hope you all liked these headcanons.

I headcanon that before Jevil was locked up and seam and Jevil were friends, Seam and Jevil would just play pranks on Rouxls. Seam would distract Rouxls kaard with some story (rambling old people story talk) while Jevil would sneak up behind him and give him a fright. And when Rouxls would blame Seam.. Seam would just calmly smile at him and laugh.

Kris gives off quietly chaotic vibes and I love that.

Like, they spend half a second in prison and then "perpetuates the cycle of existence" (aka eats moss) like "This is my life now"

I bet that if instead of threatening Kris when Susie ate the chalk, and she some offered instead... Kris would have eaten the chalk without a second thought.

Since the own-flavored tea tastes different for each character, Berdly tea would just be different flavors of boiled Gatorade

SNOWGRAVE NOELLE HEADCANON.

The more the route goes on, the more her antlers and her hair grow until she kills berdly, in which her antlers are huge and her hair has a trail. Her eyes are now permanently white in her dark world form, but she can still see.

Some spoopy writin stuff under the cut :3

When Susie walks into Noelle's room in the castle, it's covered in ice and is near below freezing. She sits on a throne of ice, icicles and stray hair strangs hanging off of her long antlers. Her hands are blue with frostbite, and her eyes were completely white. Her hair is tangled with snowflakes and is a pale, almost sickening light green.

As she sits, the words repeating in her head.

"Proceed."

"Proceed."

"Proceed."

"PROCEED."

The sickening words that led her to this madness. The words that lead her to be stronger but lead to so many peoples misery and deaths. The more she thinks of the monster she has become, the more the room contorts and shifts.

The player got their strong weapon and their alternative route.

The ring of thorns against her blue hands, dripping blood onto the icy ground as she sits there on her throne. She stared outside the window at the snowy flurry she caused. How many lives had she taken? How did she even get here again? Her memory was starting to get hazy.

But really, who could blame her?

But what did Noelle get?

Nothing but pain.

I love how we can all agree that jevil and spamton are divorced

Seam; before and after

I was doodling some Deltarune characters and I sort of remembered that Seam used to look different but then got in a fight with Jevil and was all torn up and such so here we are today

Since Seam used to be the royal magician, I figured that before he fought Jevil his whole body had a strong magic in it and now only his tail can use magic. The reason why his face is lit up/bright in the game is from the glow emanating from his tail

His lil button nose had fallen off, his legs and right arm were ripped from his body leaving him only being able to crawl, and part of his mouth was sown together. But these are all just a bunch of headcannons I have because why not

Ok the poll hasn't actually ended yet but it's definitely trending in a Cool Deltarune Idea™ direction, so here we go

Let's think about this with layers of reality. We're at the top, then there's Undertale. Gaster's weird thingamabob that got him shattered was Deltarune, an unnatural side branch of reality jutting out. Because of its properties as fucked up nonsense, you can much more easily create further growth, these ones another layer down. Dark Worlds as we typically see them. As for the Gaster falling in, I think there's another detail. He didn't stumble or trip, he was pulled by Deltarune Gaster who was up to his own fucked up science shenanigans. Since I don't want to be constantly saying full titles, they're now UTG and DRG. Ever noticed how some events in dark worlds seem to have happened before the fountain opened, despite being too specific to be the kind of metaphor transition often seen? I think they have potential existence, all of the ones opened and all others as well. Half realities. Normally not much weird shit can happen because they're disconnected, but there's an exception. UTG got shattered across space and time, so he can do whatever. I think he's making the secret bosses Cuckoo For CoCo Puffs for, I dunno, fucked up science purposes. Or kicks and giggles, being shattered across space and time sounds boring. Meanwhile, I think DRG is the Roaring Knight, probably motivated by some sort of science shenanigans.

I have little to no proof, but it sounds cool. Please tell me if you find evidence for or against it, or ask questions.

I have a lot of things to say, but since I'm in the middle of drawing my interpretation of the Addisons and Spamton, I don't want to reveal all of it in there, but here's a summary:

-The department in which Spamton used to work as an Addison was the "Screwups" department, and while he was definitely the worst at his job, his coworkers were also considered to be bad at their job.

-There are 5 kinds of Addisons who are all manufactured, the 5th one being the red Addisons, who are basically the boss of their departments. They are always in their office, doing paperwork and swimming in money Picsou style, which is why you don't encounter them in game. There's no way these rich bastards would go through the effort of socializing with the disgusting and pathetic middle class, the horror! Give money to the poor? Don't even think about it!

-Spamton was supposed to be a red Addison, which can still be seen with his red cheeks. However, there was a problem during his "birth", and he ended up coming out a defect.

-I fucking love the orange Addison so much that I made him the boss of Spam's department, and I made him the jolliest and most supportive guy you ever m- Freak, that's just As gore whole character without the trauma.

-Spamton and Pink have gone through many arguments throughout the years, but all of them always end the same way: with Spam kicking Pink in the nuts. And even after 30 years, Pink still hasn't learned to fucking dodge, so you end up with a Spamton who, after being thrown in the trash, sometimes sneaks into Pink's tea shop, throws a pipis at his crotch, laughs like the maniac goblin he is, then leave without giving an explanation. He does this every few weeks. Pink still hasn't learned to dodge after 30 years of being punched in the dick.

Hey lads, what are some of your Addison headcanons?

Personality, general species biology, story stuff, etc. Anything Addison (Spamton included) related

Figured i'd draw my headcannon Mike again, cause I hardly see any art of him just being chill. His design probably needs a bit of elaboration, but in short, I based him off toriels tv.

quick little head cannon that i wanted to share.

I’ve seen it theorised that theres more to the house behind the dinning room table. I’d like to propose that one of the things on the other side of the room is a grand piano. A piano that Kris could learn to play on.

i like to believe this because their are only a few places where another piano that Kris could learn on could be. The hospital one doesn’t count because it’s missing most of it’s keys. There could be one in the church but Father Alvin never asks Kris to play it, at least not yet. 

ok so, if Noelle's Dad’s name is Rudy, short for Rudolph. Does this mean she has uncles and cousins named after the other reindeer that pull Santa's sleigh?

Uncle Dasher, cousin Vixen? 

..is Rudy like, estranged because he was born with a red nose?... no i think that’d be messed up.

for comparison

My real Deltarune theory is that Hometown is a dark world based on this carpet

I like to believe that Kris’ full name is actually Krismas. A name bestowed upon them by Rudy, a man who was not gonna let his best friend name his new child ‘baby’.

because we all know how Asgore is with names
