allow him to retain their powers for prolonged periods. However, Doom's true intention was to kill the Parasite by allowing him to absorb so much power that his cells would burst, causing the Parasite to, according to Doom's calculations, transform into a crystalline mass that would allow Doom to perfect the reactor by using its energy-manipulation abilities to control the reactor's power output. This plan was thwarted when the Parasite briefly absorbed Spider-Man's powers, causing his borrowed spider-sense to alert him to Doom's treachery in time for him to turn on Doom and destroy the equipment that would have allowed him to absorb the powers from Superman, Wonder Woman and the Hulk, although he was subsequently defeated by Superman using a gauntlet of Doom's that prevented the Parasite from absorbing his energy when he was attacked. JSA: The Liberty Files In the second JSA: The Liberty Files miniseries entitled JSA: The Unholy Three, the Parasite is a former KGB agent working freelance as a contract killer. Justice Justice features the faceless Pre-Crisis version of the Parasite as part of the Legion of Doom. While not identified by name in the story, it is revealed via Batman's computer files that this version of the Parasite is Raymond Maxwell Jensen. He first appears in issue #4 as part of a group of villains sent to kill Superman (alongside Bizarro, Solomon Grundy, and Metallo), draining Superman's powers before Metallo exposes Superman to his kryptonite heart. The quartet are soon defeated by Captain Marvel, who slams Metallo's heart into the Parasite to defeat him. Lex Luthor teleports to the group almost immediately after Marvel and Superman leave to the Batcave, literally scolding the group as he returns Metallo his heart, telling the Parasite he also gets Superman's weaknesses as well as his strengths. He is later seen giving Luthor an unconscious Supergirl. When the Justice League attacks the Hall of Doom, the Parasite initially attacks Aquaman using some of Supergirl's powers, hoping to take his powers, and threatens Mera's life, and is subsequently stabbed by Aquaman. Gold later tries to imprison him in his body, hoping to turn the Parasite into gold, but is distracted after Platinum is attacked by Metallo. After escaping, he takes Black Adam's powers and Metallo's heart to kill Superman, but he is still unable to beat the Man of Steel and is defeated by the lightning bolt from Black
