Home to Lilliputian versions of Superman, Batman and the like, froliking in a world without death or violence until their Superman and Batman were butchered by the monstrous Superdoomsday of Earth 45. Dick Grayson succeeded Bruce Wayne as Batman, only to learn the terrible truth of this seemingly innocent world: they are in fact robots, controlled by the Empty Hand, in order to spy on the House of Heroes, as well as live and die repeatedly to test its plans.
