through polling selection. This Superman died early in the one-shot, leaving Supergirl to carry on, ultimately sacrificing herself. The Pocket Universe Superboy was created as an explanation for the existence of the Legion of Super-Heroes after Crisis on Infinite Earths. He is essentially identical to the Silver Age Superboy, the young version of Superman who becomes a Legion member, and he is far more powerful than the post-Crisis Superman. This version of Superboy dies saving Earth of the Pocket Universe in Legion of Super-Heroes #38 (1987), years before he would have become Superman. Other characters known as Superman Kon-El, the modern Superboy, is a clone created from the combined genetic material of the Man of Steel and Lex Luthor. He arrived in Metropolis shortly after Superman's death. Originally, he had no name besides "Superman". When the original Superman returned, he declared that the clone had earned the name "Superboy", much to his dismay. Superboy eventually became a hero is his own right, and Superman came to think of him as family, giving him the Kryptonian name of Kon-El and the human alias Conner Kent, cousin to Clark. Originally, Kon-El's origins were depicted as being created from genetically altered human DNA and made to look like Superman and to be as Kryptonian as possible, manipulating Superman's bio-electric aura into a telekinetic field, but eventually this was retconned so that 50% of his DNA actually does come from Superman (despite Cadmus earlier concluding that this was impossible due to the far greater complexity of Kryptonian DNA). They also learned that the genetically altered human DNA came from Luthor, rather than Paul Westfield as initially stated by Cadmus. In a future depicted in the Titans Tomorrow story arc, Conner becomes a tyrannical Superman after Kal-El dies again. Although Conner died during the Infinite Crisis (2006), his future self, as Superman, is part of a story arc in Teen Titans, published in late 2007. The second Titans Tomorrow Conner is Tim Drake's clone of the original. The first Conner returned to life during the events of Final Crisis in the story Final Crisis: Legion of Three Worlds and remained active within the DC Universe up until The New 52 reboot, where he is once again just beginning his career as a superhero. Hank Henshaw was one of several to claim the name of Superman, following the original's death. To differentiate him from the others,
