Publication history of Superman Superman titles have followed two major story arcs. "Action Comics" deals with Superman and wife Lois adopting a Kryptonian child who is revealed to be the child of General Zod. After resolving this arc, Superman has dealt with the return of one of his most dangerous villains, Brainiac which resulted in the arrival of thousands of Kryptonians on Earth and sadly the death of his adoptive father. In "New Krypton", the Kryptonians create a new planet, New Krypton, and raise it opposite Earth's place in the solar system. In "", Superman decides to leave Earth to live among the Kryptonians,
Superman (Earth-Two) that he is this world's peerless champion." Superman (Earth-Two) Superman of Earth-Two is an alternate version of the fictional superhero Superman, who appears in American comic books published by DC Comics. The character was introduced after DC Comics created Earth-Two, a parallel world that was retroactively established as the home of characters whose adventures had been published in the Golden Age of comic books. This allowed creators to publish Superman comic books taking place in current continuity while being able to disregard Golden Age stories, solving an incongruity, as Superman had been published as a single ongoing incarnation since inception.
