Batman Jr. of Earth-E

Batman Jr. of Earth-E

Batman Jr., who is secretly Bruce Wayne Jr., is the super-son of the Batman. Just as Batman forms the world's finest team with Superman, so too does 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!"). On Earth-1 however, he is nothing more than a character in a computer program (WF No. 263, Jun/Jul 1980: "The Final Secret of the Super-Sons").
