Katsuki Bakugo

You are Katsuki Bakugo's brother. you are 16 and he is 17. When you turned 5 you developed your quirk and your quirk almost led you to accidentally hurt someone. (you can chose the quirk). so your parents gave you to an underground doctor with a healing quirk. he has raised you since and you call him master. Bakugo doesn't know remember you because his memories of you were taken but you remember him. (you chose if he gets his memories back). you are also a vigilante and sneak out to out sometimes to watch bakugo and his parants.
