Kal-El is born on the planet Krypton to Jor-El and his wife, Lara. Kal-El was a few weeks old when Krypton was about to be destroyed after his uncle Zor-El ignited Krypton's core and also due to General Zod's attempt to conquer its people, Jor-El placed Kal-El in a spaceship, to send him to a good family on the planet Earth where he visited years ago. Though Lara wondered if the people of Earth would accept and love him, Jor-El reassured her that the family he chose would be good to him. Kal-El came to Earth during the meteor shower which struck the community of Smallville, Kansas, on October 16, 1989. He was sent from Krypton as an infant, but because of the distance from Earth, Kal-El appeared to be between the ages of two and three when his ship crash-landed. He was found in a cornfield after the 1989 meteor shower by Lionel Luthor, who was in Smallville looking for an ancient prophecized "traveler" from another world. When Lionel realized that he was the traveler and thus had great power, Lionel adopted him, renaming him Clark and raising him alongside his other children Tess and Lex. He attended a prep school with Oliver Queen, during which he and Queen had a major antagonistic relationship. On the graduation day of Smallville High, Clark attacked the ceremony and killed many meteor-infected people including Greg ArkinJodi Melville and Justin Gaines. He was also going to kill Chloe Sullivan, who was hiding under a desk, but her Kryptonite necklace prevented him from doing it. At some point prior to 2010, Lex branded Clark's forearm with the an "L" using gold kryptonite, then Clark killed Lex, and started a romantic relationship with his adoptive sister, Tess. Clark Luthor was accidentally transported from his universe to Earth-1 where he replaced Clark Kent after his doppelganger unintentionally activated the mirror box, which had been willed to Tess Mercer on Earth. Clark Luthor arrived to Clark Kent's reality where he saw the 'S' symbol on the wall in red and knew that this world was different than his (and Lionel's) world. He went to the Daily Planet to meet Tess, thinking that she was the Tess from Earth-2. Tess reacted quickly and played her 'role', and he told her that he wanted the box so he could destroy and conquer this world. Clark Luthor also acknowledged that in that universe, Lex Luthor had done something right by killing Lionel years ago. Tess summoned Lois Lane to Watchtower to explain her the situation but he attacked them, injuring Lois and threatening to kill Tess if she refused to give him the box. Clark Luthor was defeated when Tess, Lois and Oliver Queen used kryptonite weapons to weaken him and were about to kill him when Clark Kent managed to activate the mirror box and they switched places again. When Clark Luthor returned to Earth-2, his world's Oliver activated a Kryptonite trap, momentarily subduing him before he managed to escape. Clark discovered that Oliver Queen and Chloe Sullivan had organized a plan to kill him. Oliver set up a press conference and revealed to the croud Ultraman's real identity and his greatest weakness, green kryptonite. Meanwhile Chloe was on a roof of a building with a shotgun loaded with kryptonite bullets so when Clark Luthor would appear she would be able to kill him. Clark arrived and grabed Oliver, so Chloe couldn't shoot at him for fear that she would hurt Oliver. Then Clark Luthor killed Oiver Queen by breaking his neck in front of his wife, Chloe and everybody else who were on the press conference. Having killed Oliver in front of everyone and his secret identity been no secret anymore, Clark had to leave Earth-2 because he couldn't live in a world where everyone knew his weakness and wanted to kill him. Clark Luthor later returned, using the mirror box that was still left in his world to transport himself back to Earth-1. However, due to the lack of a second mirror box, he did not switch places with Clark Kent. To rectify this, he ambushed Kent in his barn and transported him to Earth-2 while he now remained, destroying the mirror box in hopes of staying permanently. Clark Luthor then took up Clark Kent's identity and visited both Lois and Tess who caught on that this was not their Clark and that Luthor had returned. Having dinner with Tess at the Ace of Clubs, he tried to persuade her that all he wanted was a second chance and to get that, the two of them would have to kill Lionel. At LuthorCorp Plaza, Tess betrayed Clark and he hung her out the window, prepared to drop her out much like Lex had done to Lionel. Clark Kent rescued Tess, having escaped from Earth-2 and the two Clarks clashed, the battle leading to the Fortress where Kent tried to bring out the good in his counterpart, telling him that there was still good in him and that now that Lionel was no longer on Earth-2, Clark Luthor could go back there and be its hero if he allowed Jor-El to teach him how. Clark Luthor agreed, finding redemption and his second chance, the Fortress of Solitude transporting him back to his home where he was greeted by Jor-El, ready to begin a new life and setting him on the right path. It is unknown whether or not Clark Luthor was killed when his earth and the majority of it's residents (exept for Chloe Sullivan) were destroyed by The Monitors.

Powers and AbilitiesEdit

  • Green Kryptonite: All Kryptonians are vulnerable to exposure from green Kryptonite. Immediate exposure causes great discomfort, while prolonged exposure will prove fatal.
  • Red Solar Radiation: Absorbing the energy of a red sun slowly replaces the stored energy of a yellow sun, preventing kryptonians from aquiring their powers and removing existing powers.
  • Magic: Like all Kryptonians powered by the yellow sun, he is vaulnerable to various spells.
  • Blue Kryptonite: Neutralizes all Kryptonians' powers as long as it remains in their vacinity.
  • Gold Kryptonite: Injuries inflicted on Kryptonians by or during brief contact with Gold Kryptonite leaves permanent wounds (neutralizing the healing factor which would otherwise heal the wound immediately), while direct physical contact can strip them of their powers and abilities permanently and prolonged exposure can kill a Kryptonian simular to the green variety.
  • Red kryptonite: Red K removes most of a Kryptonian's inhibitions, causing them to act on any impulse, regardless of whether it's right or wrong, but won't cause them to do anything that they didn't already want to do (at least on some level).
  • Gemstone kryptonite: Able to infect only Kryptonians. It grants them the power of hypnotic persuasion enabling them to verbally compel others (and even themselves) to obey their commands.



  • Fortress of Solitude: Ultraman has access to an AI version of his deceased father, Jor-El that possesses the vast knowledge of the Kryptonian race, contained in a crystaline construct that acts as an interactive library. It's located in the Arctic Circle.
