Batman Jr. of Earth-E

Batman Jr. of Earth-E

Batman Jr., who's secret identity is Bruce Wayne Jr., is the son of Batman. On Earth-1 however, he is nothing more than a character in a computer program. Just as Batman formed the world's finest team with Superman, so too did Batman Jr. team up with Superman's son, Superman Jr. to form the team of the Super-Sons (WF No. 215, Jan 1972: "Saga of the Super-Sons!").
