Im immortal(Mha x male autistic reader)

Your immortal. Like seriously immortal. You were playing with your father police gun and shot yourself in the head and your were perfectly fine. Your body regenerate even if your head is cutted off and you don't feel any pain. Your quirk also allow you to become stronguer each time you get in a situation that would kill a person. Meaning that every time you get curshed or burned or impaled or eat an explosion in the face you get stronguer after coming back from the dead. like the saiyan yeah
