Owlman

Thomas Wayne, Jr. is Owlman, a member of the Crime Syndicate of Earth 3. He is an evil counterpart to Batman.

Thomas Wayne, Jr. was the eldest son of the Waynes - Thomas Wayne, Sr. and Martha Wayne - who were one of the richest families in Gotham. Due to his belief that his parents were managing their wealth poorly, Thomas decided to murder them. Before doing so, he attempted to convince his younger brother, Bruce, to help him. When the time for the murders arose, Bruce was hesitant and attempted to dissuade Thomas. Thomas perceived this as a sign of weakness and thus murdered Bruce while his butler and servant, Alfred, murdered their parents. Though done by his own hand, Bruce's death deeply saddened Thomas; Bruce was the person whom he loved the most.

Over the years, Thomas began to assert his power and dominance over Gotham by adopting the persona of the villain Owlman. He used this costumed identity to strike fear in his foes; blackmailing, threatening, and paying off everyone important in Gotham, until the city was essentially his. He recognized that for normal humans to have power, they must gain it through systems of order, and he worked to establish and maintain those systems through fear. Despite his immense power, a void in his heart remained where his brother's love once lay.

Owlman, along with the newly-formed Crime Syndicate - the most powerful team on Earth - managed to dominate the world. Despite their immense power, the Crime Syndicate could not defeat the Anti-Monitor, a dimensional invader who wiped out most life on their Earth, and they were thus forced to seek out a new universe to travel to. Deciding to escape to Prime Earth, Owlman and his allies attempted to make the crossing, but failed. For five years they were trapped between dimensions, until Pennyworth, who had come through, engineered an escape.
