Multiverse

Everything has been great. Sure it's been two years since the whole moving to the surface, but some humans weren't use to the idea of monsters on the surface. But they seemed to hate you the most. Mainly because they knew you were human before. Yeah, half of it was great. But Sans always made it better for you, so one night you texted him to come over but he doesn't come. You go investigate only to find part of the forest used as a battle field. Then suddenly she finds three sugar skeletons looking just like her. But the angry mean one has a spade instead of a heart, the over excited one with a clover and the more Hispanic one with a diamond. Let's hope this doesn't end badly.

All but you and the other versions of you belong to the orignal owners. Undertale belongs to Toby Fox, I have no idea who created Underfell Sans, Underswap Sans or Sugartale Sans but they sure as heck don't belong to me. Errorsans belongs to CrayonQueen, Inksans was created by Jokublog (who also made Dreamsans). I own the plot but not the characters.
