Owlman (Thomas Wayne, Jr.) is a 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. Owlman is voiced by Diedrich Bader and James Woods in the 2008 animated series Batman: The Brave and the Bold and 2010 animated feature film Justice League: Crisis on Two Earths respectively, while Jayda Eyles portrays a young gender-swapped version of the character, Samantha Thomas Wayne, in the 2022 third season of Pennyworth in a recurring role, after being introduced as a baby in the 2020 second season finale. In December 2022, series showrunner Bruno Heller expressed interest in the character becoming a vigilante herself as the series approached the timeline of Gotham. Publication history Owlman first appeared in Justice League of America #29 (August 1964), created by Gardner Fox and Mike Sekowsky, while Thomas Wayne Jr. / The Boomerang Killer first appeared in World's Finest #223 (June 1974), created by Bob Haney and Dick Dillin. In JLA: Earth 2 #1 (January 2000), created by Grant Morrison and Frank Quitely, Owlman and Thomas Wayne Jr. are retroactively established to be the same character, and they were consequentially as such depicted as a composite character across all DC Multiverse multimedia as of November 2022. A female version of the character, known as Samantha Thomas "Sam" Wayne guest starred as a baby in the 2021 second season finale of the V for Vendetta/Gotham prequel television series Pennyworth, with child actress Jayda Eyles assuming the recurring role in the series' 2022 third season. Fictional character biography Earth-Three Originally, Owlman is a super-intelligent supervillain whose real name was never given. He was created as an evil counterpart to Batman. He is a member of the criminal organization known as the Crime Syndicate of America, who originated and operated on the reverse Earth-Three. In some of the pre-Crisis Crime Syndicate appearances, the Earth-Three Owlman also had the ability to briefly control other people's minds, though it is unclear how he acquired this ability.
