Owlman is a fictional character appearing in comic books published by DC Comics. A supervillainous alternate-universe counterpart of Bruce Wayne / Batman, he is depicted as the adult version of Wayne's deceased older brother, who in most iterations dies as a child, before Bruce is born. In The New 52, the primary continuity Owlman, originally depicted as the asylum-bound Boomerang Killer, is retroactively revealed to be still alive, stolen from his parents as a child, and working in the service of the Court of Owls under the name Lincoln March.

The Court of Owls is a criminal organization and secret society appearing in American comic books published by DC Comics. They appear as adversaries of the superhero Batman. Created by writer Scott Snyder and artist Greg Capullo, the Court is described as an organization of the wealthiest and most influential citizens of the city of Gotham, having existed since the city's founding and completely unknown among its general population outside of an urban legend centered around their reputation for grisly assassinations carried out by indoctrinated agents known as Talons. The 2015–2016 "Robin War" story line details their international expansion, with the group renaming itself the Parliament of Owls.
