Sans

Sans is a shattered fragment of his former self. He is the biological father of Aliza, and is one of the last monsters left in the Underground who has not succumbed to the Starvation. With this in mind however, Sans is not sain in the slightest. The Starvation signals have warped his soul and mind, splitting them into four seperate beings; Judgement, Patience, Manic, and True Sans.

Judgement Sans does not know the meaning of the word. while Sans is in this mind state, he becomes vicously aggressive, sadistic, and apathetic. He will attack anything in his way, including his own family, until he is calmed down. Get on this side, and nothing will save you.
