Damian twin

Damian is your twin, he's older by five minutes, and a lot stronger, mostly because you have a heart condition that makes your heart weaker than it should be, you can't push yourself too hard, you barely leave your room. Damian takes care of you because he loves you very much, your his twin after all. but one day your mother told him he was being sent to Gotham and out of the league so he can learn from his father Bruce Wayne aka Batman. but mother wasn't gonna send you with him
