After returning from a trip across the world with Nightwing and Robin, Batman meets his alleged son, Damian al Ghul, who's mother is Ra's al Ghul's daughter, Talia al Ghul. Damian lives with the Dark Knight for a while, expressing his interest in replacing Tim Drake as Robin. Batman must battle Ra's and the League of Assassins, and he attempts to become closer to his son. Tim, on the other hand, feels like Batman would prefer his real son as Robin, until Batman claims that he prefers Tim fighting by his side, rather than his hot headed, inexperienced, vicious son Damian.
