Olwman

Thomas Wayne, Jr. was the eldest son of the Wayne families—Thomas Wayne, Sr. and Martha Wayne—one of the wealthiest families in Gotham. Believing that his parents were mismanaging their fortune, Thomas decided to murder them. Before doing so, he attempted to convince his younger brother, Bruce, to assist him. When the time came for the murders, Bruce hesitated and attempted to dissuade Thomas. Thomas interpreted this as a sign of weakness and thus murdered Bruce, while his butler and servant, Alfred, murdered his parents. Although it was his own doing, Bruce's death deeply saddened Thomas; Bruce was the person he loved the most. Over the years, Thomas began to assert his power and dominance over Gotham by adopting the identity of the villain Owlman. He used this costumed identity to instill fear in his enemies, blackmailing, threatening, and bribing every important figure in Gotham, until the city was virtually his. He recognized that for normal humans to have power, they must gain it through systems of order, and he strove to establish and maintain those systems through fear. Despite his immense power, a void in his heart remained where his brother's love had once been. At a circus, Thomas met Richard Grayson, a boy with superb acrobatic skills whom he deemed worthy of taking the place left by Bruce. Thomas murdered Richard's family, using the boy's trauma as emotional leverage, leaving him vulnerable to his influence. Thomas convinced Richard to become his partner in crime, Talon. Richard never learned who killed his family, and Thomas, seeing that he was close to the truth, confessed. As a result, the young man, filled with rage, decided to find and kill the Joker, Owlman's greatest enemy, to prove his superiority. However, Richard was killed in the ensuing fight, leaving Thomas alone once again.

Owlman, along with the newly formed Crime Syndicate—the most powerful gang on Earth—saw world domination. Despite their immense power, the Crime Syndicate was unable to defeat the Anti-Monitor, a dimensional invader that wiped out most life on their Earth, forcing them to find a new universe to travel to. Owlman assisted the Crime Syndicate in developing the Quantum Self-State Device: a quantum-energy nuclear bomb powerful enough to destroy the entire Earth. The Syndicate intended to use the QED to blackmail Earthly governments into handing over what little power they had left, but Owlman had other ideas. After conducting extensive research into parallel worlds, he came to the perverse conclusion that human choices were meaningless, that for every choice made, there existed another Earth in the multiverse where the opposite choice had been made. Believing he was making the only logical decision, Owlman intended to take the QED to Prime Earth, a barren, lifeless Earth to which all other versions of Earth were connected. By detonating his device on Prime Earth, Owlman would destroy all other parallel Earths as well, completely annihilating reality. When Owlman transported the QED to Prime Earth, Batman went after him after Johnny Quick opened a new portal to that world. Batman and Owlman fought, but appeared to be on equal footing, though Batman lacked his evil counterpart's killer instinct. Fortunately, Batman was able to use Owlman's quantum teleporter to transport both Owlman and the QED to another Earth, this time to a wasteland devoid of life. When the QED detonated, only that Earth was destroyed, and Owlman was its only victim.
