Damian Wayne
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. Damian Wayne is the biological son of Bruce Wayne/Batman. His mother is Batman's love interest Talia, and his grandfather is the Batman villain Ra's al Ghul. 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. Damian is Bruce's youngest and only biological child in mainline DC continuity, with him having four older adopted siblings: Dick Grayson, Jason Todd, Tim Drake, and Cassandra Cain.
