Bakugou

Random idea at 1 AM. Your quirk is Kitsune(or fox. Look them up.) And Bakugou doesn't know. So one day, he was walking through the woods and saw a fox, (choose your color(s)) said fox was you, but he didn't know, so he picked up the fox and carried it home, unknowing it was you. And the reason you can't change back is because you were attacked in fox form with a quirk canceling bullet, the first model, so they don't take it permanently, but now you're stuck like that.
