Damian

Damian is the child of Bruce Wayne and Talia al Ghul and thus the grandson of Batman villain Ra's al Ghul. The character was created by Grant Morrison, and first appeared in Batman #655 (2006), the first issue of the Batman & Son story arc. Having spent his gestation in a laboratory, Damian was raised by his mother until ten years of age, at which point she left him in the care of his father, who was not 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 identity. He works with Dick Grayson, who has become the new Batman.
