|[List of appearances]|
Thomas Wayne Jr. was a crime lord on Earth-3 who became Owlman after his butler, Alfred Pennyworth (who was later responsible for forming the Secret Society of Super Villains) murdered his family. He was shown to have disdain for his parents due to his mother's abusive nature and his cowardly father killing his patients as a surgical fetish showing no remorse. Alfred also caused the death of his brother Bruce. Unlike him, Bruce loved their parents. He would later try to replace Bruce with a young acrobat, Dick Grayson, whose parents he got murdered, in order to later make him his partner, Talon. Talon was later murdered by the Joker. He later travels to Earth Prime, claims control of all crime in Gotham, and joins the rest of the Crime Syndicate in the fight against Batman and his allies. Owlman later accompanies Superwoman to Arkham Asylum where they spring its inmates and capture Nightwing. In the final battle against the Crime Syndicate, Owlman joins the Crime Syndicate in fighting the Justice League and Lex Luthor's team. In the aftermath of the battle, Owlman is mentioned to still be at large. He reappears at LexCorp. A deal takes place between him and Lex Luthor, which involves Luthor providing him with Superwoman's child in return for Owlman's help in defeating the Anti-Monitor.
After the Anti-Monitor and Darkseid are destroyed in battle, Owlman fled by teleporting using the Mobius chair since Ultraman and Superwoman were killed in battle. Later, Owlman appears on the moon where he was trained by Metron who was the previous owner of the Mobius chair. When Owlman accesses the secrets of the universe, he is vaporized with a flash of blue light by Doctor Manhattan.
