Fan Casting Owlman in Justice League: The Looking Glass

Thomas Wayne Jr. was the eldest son of the Waynes-and because he believed his parents were mismanaging their wealth, he decided to kill them. Before doing so, he tried to convince his younger brother, Bruce, to help him, but he hesitated and tried to dissuade Thomas, who defined this as a sign of weakness and thus murdered him, while his butler, Alfred, murdered him your parents. Although he was precisely responsible for his brother's death, Owlman admits during his confrontation with Batman that he still feels some remorse for what he did that day.
