Okay so you had a pretty bad childhood meaning that you were neglected and left out by your parents a lot so you fended for yourself and didn't eat much, you wanted to be a hero so bad when you were little but never got a chance UA so all your dreams basically came crashing down on you which became a lot of prssure and you eventually became a powerful villain due to no attention or help from your parents (yes very sad)
Y/n was raised by a gang, they never treated her well but kept her alive in return of her helping with jobs (she never wanted to do but was hit was she didn’t obey.)
You saved powder one time as a kid. Vi, Milo and Claggor were in the last drop, while Powder was outside looking for scraps to use on her gadgets. Some gang members called from down the alley “Aye, kid!” “Watchu lookin’ for?” And things quickly escalated.
You two get shoved into a locker together at the end of the day, meaning you’ll be there all night! Ein and you have a frenemies kinda relationship (he also kinda crushes on you), he teases you, you annoy him, shit like that.
You were just on your way back to home when you saw that group of ‘strays’ sprinting past you. One girl, a girl with pink hair and..arm muscles that you could not just ignore, had a rucksack on her back filled with stolen goods. Being chased and yelled at by enforcers.
