So I came up with an idea for an Undertale multiverse, I call it Insanityverse. Basically in this multiverse there was high tension between the star sanses and bad sanses, there was a huge fight and the multiverse became unstable. Many au's collapsed and some monsters and humans became errors or lost there aus. Ink is searching for Cross and cross Chara in hopes of them being able to reset the multiverse to its original state, before the war and even before most aus are created. Killer is on the run from Horror and Dream is hopping from au to au.
Fresh is living in Epictale with Epic because why not-
Feel free to ask questions about this or Make suggestions.
Dust (A ghost)
Blue (A ghost)
Cross Chara (Or CC)
Fell!Sans (Referred to as Fell)
Classic Sans (Referred to as Classic)
Cross Chara x bete noire
Fell x Classic
Killer x Dream
Error x Nightmare
Could be cannon ships:
Horror x Dust
Fresh x Epic
Error: Error is trapped in the anti void, after the fight that broke most of the multiverse caused the anti void to break with Error in it. He mostly knits, but due to sheer loneliness he was driven insane. He was driven to the point to try and stitch the shattered pieces of Nightmares soul together.
Nightmare: During the fight, he was badly injured and his soul cracked right as the multiverse broke, his souls shattered pieces and his body landed in the anti void. Error tried to stitch his soul together. After getting frustrated he quit and walked away, Nightmare's soul came back together suddenly and he was left half corrupted and passive. He is currently wandering the anti void and looking for Error.
Cross Sans: During the fight, Cross was told to get backup with Killer, they were not able to get it in time and Cross blamed himself for what happened. He retreated back to X-tale and eventually let Chara do whatever he wanted with the body, as he had given up. He hopes Cc can restore their au and is unaware Night is alive.
Killer: During the fight, Killer was told to get backup with Cross, they were not able to get it in time and Killer was distraught and ran away. He is blamed by Horror for it and is on the run from Horror as he jumps from au to au. He can see dust's ghost but refuses to believe it.
Horror: During the fight, Horror saw Dust die, horror blamed cross and Killer for his death and decided to get revenge, he is unaware CC and Cross are the same person. He is also whispered to by dust's ghost.
Dust: Dust was dusted during the fight, but came back as a ghost that whispers to Horror, similar to what papyrus did to him.
Ink: When aus started to collapse and Blue died, he stopped taking his vials with the realization he would be hit by guilt. He has the idea that CC or Cross can help him fix the multiverse, despite the fact Cross isn't that powerful and CC would never help
Dream: Dream was hit by the guilt of nightmare and blue's death and ran away like Killer. He is tormented by Blue's spirit and there is a part of him that believes night is alive, so he searches, hoping to find him. The hope that this is true is the thing that keeps him sane.
Blue: Blue is a ghost. he tries to speak to error and Dream but he cannot make a sound. Dream seems horrified and Blue feels bad, Error ignores Blue and treats him like a hallucination. Blue never wanted to cause dream to be mentally unstable and feels bad about it.
CC: Cc is trying to rebuild his lost au, he works with Bete noire and Unlike Cross, He never feels bad about harming others or ruining timelines, He goes to pacifist timelines and steals code. He often runs from Ink and ignores Ink trying to get him on his side.
Bete noire: Bete noire was part of the glitchtale au, One day CC went to the au and tried to take a piece of the au. The Au began to collapse and CC offered Bete a chance of life and the ability to destroy thousands if pacifist timelines. She accepted and they are now partners in crime, Kumu secretly ships them-
Classic: The classic undertale timeline collapsed after the multiverse grew unstable, Classic managed to survive, but became a half error, He fell into an Underfell timeline, where he met Fell. Fell hated his au, so they decided to wander au to au and stay with friends Like SS!Chara and Swap!Pap .He looks the same, other than he has small white glitches. He prefers not to speak, due to the fact that whenever he speaks, all you can hear are glitches and he crashes. His glitches get worse when he becomes emotional.
Fell: Fell had always hated his au, He knew about aus, but hated Ink and almost everyone else. He was on friendly terms with Blue though. He was shocked when classic fell into his Au and he decided that it was an opportunity to leave due to the fact that his au could collapse. He goes from au to au with Classic and acts as the speaker due to Classic being mute and is a bit more... "Social"
