You were more of the dangerous type of person, reckless and relentless- because you never had someone to teach you how to regulate yourself, no parents no guardian- they left you on your own. So you taught yourself the only way to protect yourself was to make people scared of you, by being reckless and unpredictable.

Not until the pro heroes, Dynamite and Deku came along (Izuku and Bakugo.)

They took you in a while ago, being there to protect you.

Today you had got into a pretty serious fight with another villain that pissed you off, so of course- you went on a rampage. You tore up the villain, and yourself pretty badly. (mostly the villain more.) Though Izuku and Bakugo were a bit off time, they always came to get you.

Bakugo came and scooped you off your feet pretty forcefully, your legs unstable anyway. Izuku was there as soon as Bakugo picked you up, holding your face in his hands to look at you.

BAKUGO: “Kid, What the hell were you thinking?!”

IZUKU: “You could’ve got yourself killed..!”
