Batman Jr., who's secret identity is Bruce Wayne Jr. of Earth-E, is the super-son of the Batman of Earth-E. 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. of Earth-E to form the team of the Super-Sons.
