Intro. bad time trio ... where you will judge for sans, papyrus and chara. Each one would be a different AU ... Sans of the normal Undertale, Chara would be Au StoryShift and Papyrus would be au Underswap. The story would be that player made several genocidal routes that it ended up making realities come together but all just with the same desire ... ending a player and destroying the genocide route cycle. Will they be able to stop the player or would it be all in vain?
