Damian Wayne is the child of Bruce Wayne and Talia al Ghul and thus the grandson of Batman villain Ra's al Ghul. Having spent his gestation in a laboratory, Damian was raised by his mother until he was 10, at which point she left him in the care of his father, who had not been aware of his son's existence until that point in time. Damian is violent and self-important and was trained by the League of Assassins, learning to kill at a young age. After the events of Batman R.I.P. and Batman: Battle for the Cowl, Damian has taken up the identity of Robin, becoming the fifth and current person to use the Boy Wonder's identity.
