Y/n was locked up all their life in a tiny apartment as their mother would ‘train’ their quirk. All up until Y/n was six- Y/ns mother called pro hero’s to see her child and to make sure they weren’t ‘dangerous’ as her excuse- what the pro hero’s didn’t realise is that she was doing it for money- hoping to sell Y/n for big money- that was her delusion and it was severely illegal to sell kids. Y/n decided they had to run before they would come/ if they had enough time
Y/n was abandoned in a forest at four years old but survived after a mother bear found and raised them alongside her cubs. Growing up in the wild, Y/n learned to hunt, climb, and communicate with animals through simple sounds, while being warned to stay away from humans. At twelve, a pro hero discovered Y/n but was met with defensive, animal-like behavior. Realizing the situation required help, the hero brought in Nezu and Hound Dog, and Y/n was taken to U.A. High School to learn how to live amo
The League of Villains and Y/n have all transformed into toddlers from a toddler quirk. It was gonna wear off in a few days but kurogiri had to do some grocery and general shopping.. so he just teleported the group to UA in a big meeting comically and said he’ll be back later lol. The hero’s technically can’t arrest or lock them in jail. Have fun!
Class 1-A was on a field trip outside of IA- still close to the school as in a walkable distance. It was just the park around the corner.. until it wasn’t so peaceful- a few villains hit them with their quirk before Class 1-A could even react. One second they were normal- the next they all turned into very young toddlers. Aizawa was left with the chaos surrounded by his problem children who were now literal toddlers. Their attitude didn’t help either as they seemed to regress a bit.
Y/n would often regress young but was particularly stubborn about the room. Hound dog was their main care giver and always helped them when they were being stubborn. Hound dog however was sent onto a mission for a few days so Y/n took the opportunity- they would fully deny the room- they would act really stubborn if other teachers brought up regression. Until hound dog came back from his mission thinking Y/n wouldn’t cause any problems until he went to the teachers lounge…
A villain had injected purple liquid into all of them very sneakily and clever. They barely even noticed. That was until a few hours back at school they were acting more chaotic and mean. They were causing mischief and had a terrible attitude. The UA teacher noticed this the next day getting more frustrated as they were brats. They would swear, curse, prank, and sometimes were violent with anyone who touches them. Now the Teachers have to figure out what to do next
