What if after they are killed, they get reborn as something..say..angel...demons...maybe some other kind of creatures..surprising enough there is only one that is reborn as an angel and that is underswap papyrus. It even surprised him that he was reborn an angel and yet his brother was reborn as a demon. He wondered if it was because he was the royal judge? And everyone finds out he was the royal judge. Then later on he meets other alternative self's of his brother and him. After he gets kidnapped by error of course.. (Different things including personality and like always it won't be realist with how I'm writing it Don't be surprised if everything is different ok! When I make storylines like this, I change it to how I want it. So this could be a very different multiverse then the ones that you know like my other undertale aus stories! Different multiverse with different things yeah?

Undertale is a game with multiple endings, everything that you do redefines the whole world around you. But... What If...? What if Sans found you first before Toriel? What if Flowey was possessed by someone else? What if Papyrus was evil? What if Undyne never met Alphys? What if Asgore had died before the events of the game? What if... I was to tell you what would happen if those events had occurred? WARNING: MASSIVE SPOILERS I do not own anything related to Undertale.

summarized warnings / TW: needles, profanity, extremely bad insults again PLEASE do not say them out loud unless you want to get yourself grounded during a game of DARE, so much laughing... UNDERFELL created by Vic the Underfella. They don't mind the creativity we bring, therefore I am valid to make fanmade content of UNDERFELL and include headcanons and made up nonexistent words. My interpretation of UNDERFELL goes here. Sans AUs will visit platonically.

What if someone became papyrus from underswap? What if they gave their brother more freedom? What if they were the one that error kidnapped instead of sans? (Things will be different including personalities because I never seem to get them completely ALSO the AGES will be DIFFERENT I'm having papyrus as the younger brother idc is sans is the younger brother or not, I'm having papyrus as the younger brother so no complaints And it's a different multiverse maybe everything will probably be different idk yet Also give me ideas if you want me to update this story faster.
