Damian Wayne is a superhero appearing in American comic books published by DC Comics, created by Grant Morrison and Andy Kubert, commonly in association with Batman. He is the son of Batman and Talia al Ghul, and thus the grandson of Batman villain Ra's al Ghul and the potential inheritor of Wayne and al Ghul's families' wealth and resources. With the al Ghuls citing Bruce Wayne as the optimal successor to their empire, after faking a miscarriage to his father and calling off their marriage, Talia has kept his existence hidden from Batman until Batman #656 (2006). In turn, the character is revealed to have originally been intended to "kill and replace his famous father," as well as serving as a host body for Ra's al Ghul, thus, in theory, unifying the Wayne and Demon factions as intended by the al Ghuls.
