We're not born Monsters (IzuxToga)

Izuku Midoriya was a kind, caring kid who always put people in front of himself. But when he found out he was quirkless he was devastated. He thought his best friend would help him in his time of need, but instead he was just abused. He decided it would be best if he just died. But before he could, life decided to throw one last person at him. A person that was in the same boat with him. A person... with a set of sharp canines.
