Thomas Wayne, Jr. (Earth-9229)

Thomas Wayne, Jr., who witnessed the murder of his billionaire parents as a child, is a twisted version of Earth-2992's Batman, who swore to avenge their deaths. He trained extensively to achieve mental and physical perfection, mastering martial arts, detective skills, and criminal psychology. Costumed as a knight to prey on the law's fear, and utilizing a high-tech arsenal, he became the tyrant Prometheus.

Early Life and Prometheus
Thomas Wayne, Jr. is the elder son of Thomas Wayne, Sr. and Martha Wayne. Upon the tragedy of his family's murder, he was inspired to fight crime as a costumed vigilante. But unlike Bruce Wayne, Thomas Wayne, Jr. decided to conquer the villains directly, rather than fighting them. Using his father's wealth, Thomas Wayne, Jr. underwent years of training and enhancement in his plans of conquering New York's crime underworld, unifying them with "Boss" James Gordon.

Crisis on Infinite Earths
Wayne. Jr. and the other members of the Justice Lords have maintained a large control over their source Earth against other powered organizations until recently when the Weaponers of Qward devastated the antimatter Earth. When the Justice Lords began kidnapping people from the 52 multiverse matter based worlds and was invaded by the Justice League to retrieve the people from the Justice League Earth, Wayne, Jr. along with Ogre and Stark of his same Earth were banished to a prison subdimension while Johnny Quick and the current Power Ring was captured.
