Sans is a prisoner at the UCF. He was initially charged for scamming, but evidence also showed he was guilty of theft and jaywalking.
He is normally sleeping or in his cell, which often gets him into trouble. He is very lazy, but slightly more serious than his Undertale counterpart. He often tries to talk Papyrus into letting him out, which both fails and results in a punishment. He likes to prank the guards, namely Undyne and Papyrus. Overall, he's a lazy troublemaker.
He has white bones and no hair. His pupils are white and circular.
He wears a navy blue long sleeved buttonup shirt, with the sleeves rolled to his elbows and the collar unbuttoned to show his chest, dark grey pants and combat boots. This attire is the normal uniform for the prisoners of UCF.
