Kal-El II
In one of many possible futures, in which Superman has retired from crime fighting and has become a grandfather, he joins forces with his infant grandson, Kal-El II, to defeat a band of extraterrestrial robots that have been dispatched to Earth by aliens from a distant planet as the advance guard of an impending interplanetary invasion (Act No. 327/1, Aug 1965: "The Three Generations of Superman!").
