Undetale Au - Tumblr Posts

Please follow them they are very cool

First post lol

I'll be honest, posting this is like something that makes me feel anxious and stuff. Always had the problem of never being happy with posting and feeling like it's not "good enough" but yo... It just might be, a few people told me that I definitely should make an art account and stuff....! ...I mean...I do feel really proud of this one ngl ngl! 🤗

I also got back into undertale recently and wanna finally make my childhood dream of creating an AU come true-! As well as I wanna learn how to draw the cool ass skeletons and FINALLY learn how to draw goddamn papyrus, he was always a struggle🥲🥲🥲!!! He's just so funky and awesome,I guess that's why I find it so hard?? Idk does anyone else find it hard like that??✨✨✨

Honestly this is rlly stressful for me but fuck it, let's go. People might like my stuff!! :V

That's all!! Enjoy the rest of your day/night!

Yellowswap

There are folks who have done this, but I consider this a nice thought experiment which characters would replace whom in a theoretical Undertale and Yellow Swap

Chara- Integrity

Asriel/Flowey- Kanako

Asgore- Chujin

Toriel- Ceroba

Napstablook- Gardener (is now a ghost in this scenario)

Frisk- Clover

Sans- Marlet

Papyrus- El Bailador

Undyne- Starlo

Alphys- Dalv because Alphy has electric powers, also corn Yaoi is a pouluar ship

Mettaton- Axis 

Monster kid- Mooch

ASRIEL DREEMURR- KANAKO KETSUKANE

Bonus Deltarune

Kris- Cover (closest name I could find that doesn’t sound like gibberish)

Ralsei- Anakko

Undertale Cyan and Orange Cast

So context: Undertale Cyan & Orange. This was supposed to be me listing off OC and their personalities, but this became a more detail version of the above linked post.

Julien and Kai Annie, the first and second humans- bearing the cyan and orange souls respectively - to fall into the underground. Julien (orange) jumped into mount ebott on purpose because they were challenge and Kai (cyan) followed them because they have no confidence in Julien to make it out the underground alive. Julien similar to chapter one Susie is attack crazy so its up to Kai to warn the monsters or calm Julien down, also Julien has a unique meter that I’m calling the brave meter and it determines how often Julien attacks.

Oren and Staug, Are the first monsters we would encounter in the underground being where Flowey would be. Staug is an ogre similar build to Ed and Oren is a small- about the size of the two human- non descript mammalian monster, basically Rocky and Mugsy from Looney Tunes. So, they attack Julien and Kai and are about to finish them off when Toriel comes in to see what’s going on. Oren lies to Toriel that they found some humans hurt and they were trying to heal them. She believes them, but takes Julien and Kai into her care. Now over the course of our time in the ruins Oren and Staug when Toriel isn’t around will mess with us, but end up comically stooging it up. For example our penultimate encounter with them is when Toriel leaves us alone they appear and “attack” us with the element of “surprise” which ends with Oren stuck in a wall. Toriel comes back and we have the option to lie for them or tell on them. The latter option gets them really mad at us. In our final confrontation with them they refuse to heed Kai’s warning so the calm Julien act replaces another action. After doing said action we gain control of Julien and together Spare Oren and Staug. They apologize for being jerks and open the ruins doors and tell us to be safe and to survive or Toriel will be sad (Foreshadowing). Upon entering snodwin we are stopped by...

Tik and Tek identical twin monsters and the youngest members royal guard. Throughout Julien and Kai's time in snowdin they attempt to scare the duo which honestly works on Julien and every battle we would have to calm them or warn the monsters. Near the end their adventures in Snowdin they face them both wearing scary masks which permanently frightens Julien so we have to warn them and its up to Kai alone to spare them. After doing so they decid to help us. They know the other royal guards wants Julien and Kai so they lead them away from waterfall and into a new area similar to the wild east, but Julien and Kai coded. Their they meet…

Coach and Mic. Coach is an Olm monster and an old soul similar to Gerson while Mic is a four armed monster, and is the stereotypical tough guy with a heart of gold. Throughout our adventures with these two they teach us how to turn orange and cyan attacks the other color. There is a third thing they’re trying to teach us but they keep getting interrupted. Things inevitably blow up between Coach and Mic- Coach wants to bring Julien or Kai to Asgore and Mic is opposed to that -and they try to fight each other. There we learn the third thing they were trying to teach them turning white attacks Cyan or Orange. For obvious reasons they make up and they agree to help Julien and Kai plead to Asgore together. This nice moment is interrupted by the captain of the royal who throws Julien/Kai down the ravine that connects this area and Hotland they then leave but not before challenging Kai/Julien. We take control of the falling human who landed in a spider web. We are greeted not by Muffet but by…

Anasi, who let’s them out of her web and apologizes. Now compared to Muffet, Anasi is a kind soul and they agree to help the human, but its becomes obvious that they're leading us in the wrong direction even sicking a horde of spiders on us which probably couldn't be done in Undertale’s style. It all comes to a head with the inevitable fight against her and she reveals that the captain of the royal guard told her and many other monsters to delay one of the humans once they're apart. She apologizes and lets us go eventually and if you go back you get a cute scene of her and the human hugging. Meanwhile the other human along with Mic or Coach- Mic if Julien, Coach if Kai-arrive at Hotland. They see the captain enter the lab. The human enters the lab after him, only to find a fish skeleton- A fish monster that is also a skeleton- being yelled at by a walkie talkie. This is the Royal scientist assistant and technically my first Undertale oc…

Neverdead who is being instructed by the royal scientist that they should never be disturbed in his hour of brilliance. When Neverdead notices the human they simply tell them to go. Now this sets up another round of being given the rigmarole this time by Neverdead until the confrontation with them which is interrupted by the royal scientist who activated Hotland’s defenses. Now we have to fight alongside Neverdead using her green counterattack- We attack Neverdead when her weapon turns green -to destroy the defenses. After the fight and convincing Neverdead to quit her job by dropping their walkie talkie into the lava, we make it to the judgement hall we are greeted by a shadowy tall figure and things turn to black. We switch back to whichever human that fell down the ravine making it to the judement hall. The camera pans to the captain of the royal guard…

Lex end, holding a glass container that contains either the cyan/orange soul. There are no bit here, no japes, no bombastic speeches, just the human and a monster that dwarfs the height of Asgore. He walks up to Julien/Kai takes their hand-they let him -and walk to the middle of the judgement hall. He apologizes, but this is how it must end with both their soul and the battle starts. If were Julien then we don’t control this fight they fight until their hp reaches zero and Kai has it better, but Lex’s attack is a sans level bullet hell. This is a no win fight, as we have limited loads because Julien and Kai could only save and load together.

“Despite everything… It’s still you.”

So here's UB ! Frisk ! They are an anti-hero I think ? They're quite a very silent and cunning character and team up with Asriel.

okay but imagine yn x error but yn is dating geno and he goes missing so yn assumes he's dead. until years later error is destroying their universe only to spot them and kidnap them into the antivoid claiming that he is yn's dead boyfriend.

and of course he is...
