#undermirror

This is an au I've been making up myself, this is Unknown Error!Sans!! His au is a erased AU called Undermirror! His backstory is that it was destroyed by error 404 sans and he's one of the only survivors. There is a lot of things I'm trying to set in stone but I'll get there eventually 😅

He works with Nightmare sans unwillingly, but does his best to get along with everyone in the group, his glitching causes severe mood swings, like he could be chilling one moment, glitch out and all of a sudden he's either the happiest skeleton in the multiverse, or he's drowning in a puddle of self-loathing.

Original UNDERTALE AU comic

Undermirror is an undertlae AU where a scientist named W.D Gaster sends two kids and a tiny robot to another universe using a magic mirror. There are infinite amounts of mirrors which the kids can visit any universe they want. Frisk can't reset in this AU, but Sans can. Charabot is just there to tag along with the two.

Notes:(Hero is technically Sans Jr. from the future, the only difference is his eyes are blue due to him having more HP than his dad.)

(Frisk, like Hero, wasn't born at the time, meaning they never fell into the underground and freed all the monsters.)

(W.D Gaster never died in his AU which also means he never fell into the core.)

(Hero is the grandchild of W.D Gaster, while Frisk is the adopted grandchild)
