| Undertale stuck in a 'room' for 24 hours | | My AU explained in desc |

Okay so to clarify some things:
Sans is younger then Papyrus (Pap is 21 and Sans is a child but only Pap and Asgore knows as he lies about his age and never told anyone about his real age so people would think he is an adult and would help his bro get money)
He fell into the Underground (they don't know that)
Sans used to have many abilities such as shapeshifting but the barrier blocked those abilities (they don't know that)
Sans was adopted by Pap's family (found by them in the Underground forest)
Sans is not a monster but would never tell anyone bc he's trying to 'fit in' (they don't know that also) -|

His real family kinda left him (The Creators are his older sisters btw)
He's immortal (they don't know that)
He has existed for 14 000 years :D (time of existing is NOT age!)
He has fought the Goddesses (Gods) many, many times and won :P
I made him indestructible (plot armor)
mostly everything up here is not known by the Undertale characters.
the war between monsters and human happened a few thousands years ago (none of the current Undertale characters were even born)
Sans used to go to school with humans (they had A LOT of FUN - such as burning down the school - I wanna do that too :(. )
