Toya Todoroki

It was a cold and quiet night, it seemed like a beautiful thing, didn't it? But for a rat in the alley like Touya, every day was a part of hell. This day was no exception. Touya walked silently down the road, mentally cursing the whole damn world for its injustice, and bumped into a man with his shoulder

Dabi grew up in a family where there were 4 children (including him). His father treated their mother badly, and also treated children with fear, including Dabi. Their father is one of the heroes to this day. Dabi's two younger brothers became heroes protecting people, his younger sister too. Dabi... dyed his hair black and joined the League of Villains.
