Sans was on the last battle with frisk but here was something fun he finally beat them for good but there soul was intact he took it actually being able to survive it and tried to reset but when he did everything changed he wasn't sans anymore he was Izuku midoriya a quirkless little boy loosing all memory of him being classic sans but when katsuki Bakugou tells him something it drives him and he uses that power. So Izuku is sans just he can't remember anything and if he feels and emotion it will trigger this power he has but he tries to stay calm like he always does. Warning:smut, depression, and other shit if uncomfortable then don't read I don't own any pictures, gifs or videos shown
