All Might

You were the son of All Might. Unfortunately he didn't pay much attention to you, especially since your mother died, so you felt abandoned and hurt. One day you and All Might argued, he got angry, you got scared and ran away from home.

You started living in an abandoned workshop, thanks to your quirk you didn't live so badly. You stole only what you needed to live, until one day the heroes caught you. Eraserhead, Hawks and Endeavor were forcibly taking you to a police station and that's when you saw him... All Might "Son?" Said All Might.

"You don't know how much I regret it"
