Damian Wayne is a fictional superhero appearing in American comic books published by DC Comics. He is the son of Batman and Talia al Ghul, and thus the grandson of Batman villain Ra's al Ghul. The character originally appeared as an unnamed infant in the 1987 story Batman: Son of the Demon, which was at that time not considered canon. Following this, various alternate universe stories dealt with the character's life, giving him various names. In 2006, the character was reinterpreted as Damian Wayne by Grant Morrison, and introduced into the main continuity in Batman #655, the first issue of the "Batman and Son" story arc. Having grown up in a laboratory, Damian Wayne as a pre-adolescent is left by his mother in the care of his father, who previously was not aware of his son's existence. He is violent and self-important and was trained by the League of Assassins, learning to kill at a young age, which troubles the relationship with his father, who refuses to kill. However, the Dark Knight does care for his lost progeny. After the events of Batman R.I.P. and Batman: Battle for the Cowl, he takes up the identity of Robin at ten years of age, becoming the fifth person to use the Robin identity. He first worked with Dick Grayson before going to work alongside his father, upon the original's return to the role of Batman. He continued to serve as Robin until 2013's Batman, Inc. #8, in which he is killed by the Heretic, an agent of his mother and his own artificially aged clone. But during Batman and Robin (Vol. 2) #37 in late 2014, Batman is able to resurrect Damian Wayne with a Chaos Shard
