In the comics, Talia al Ghul secured Bruce Wayne’s DNA after a desert meet, taking place in the storyline Son of the Demon, and used an artificial womb and genetic editing to create the perfect warrior to lead the League of Shadows and possibly succeed Batman in the future.Damian’s existence only comes to light when the boy is an unruly teenager during Grant Morrison’s “Batman and Son,” leaving him with Bruce Wayne in hopes that caring for the boy will derail his pursuits as Batman. But Bruce inspires his son, who forges his own path away from Talia’s group of assassins and decides to train to become a hero, eventually adopting the mantle of Robin. After more business with the dangerous Anti-Life Equation in Final Crisis, Dick Grayson jumps to the role of Batman and Damian becomes his Robin after coming to respect his adopted brother. Over the course of Morrison’s run, Damian becomes a much more well-rounded individual and eventually a caped crusader as it were. In Batman #666, Damian made a pact with the devil for the immortality to keep Gotham protected forever. This version uses a lot of what Damian got from his assassin training with the lessons he learnt from his father. We shall keep you updated on further development.
