The Pyromaniac

Izuku midoriya was presumes quirkless.
And everyone hates him for it.

His mother abused him because she blamed him for his father leaving them. That and she didn't want a quirkless trash of a son.

What no one else knew, is that Izuku did, in-fact, have a quirk. A quirk that was highly dangerous and could kill people if it got out of control. So he decided that the best thing he could do was to hide it. To say he was quirkless. Little did everyone know, the sweet innocent boy that they thought he was, was only a mask that his who and what he truly was.
