Parasite

History

Rudy Jones was a worker for S.T.A.R. labs and believed that the managers held the paychecks in one of the crates. While Rudy was looking for the money, he stumbled across a strange rock found by the Action Ace ( Superman) himself long ago. Rudy was then blasted with intense radiation making him a green skinned bald humanoid (Parasite 1.0).

Jones now had the ability to absorb the life energy of other people, leaving smoldering skeletons. This power was necessary for his survival as his own body is in a constant state of hunger for energy that it can't sustain on its own.

During this time, Martin Stein, one half of the Firestorm matrix (Ronnie Raymond being the other half) learned he was dying and decided to destroy all the nuclear weapons in the world. This did not sit well with Earth's governments, particularly the United States, who sent the Suicide Squad to Times Square, where Firestorm was holding a press conference. Things quickly got out of control as the Squad and the Justice League were both intent on subduing Firestorm fought one another, and the Parasite (who was brought on the mission against the protestations of both Amanda Waller and Colonel Rick Flag Jr.) is released. He goes on a rampage and apparently kills Multiplex, only being brought under control by the cooperation of both teams. Later, he attacked the new Firestorm who easily subdued him and left him near death.

During one of his stints at Belle Reve Prison, doctors attempted to make him human again. Despite their intentions, the doctors only managed to change his skin color to the more familiar purple and also inadvertently increased his absorption power, enabling him to feed on other forms of energy, such as electricity and heat (Parasite 1.5).

After a number of years, the Parasite became involved in the plot to save Superman from overloading on solar energy. Rudy and Superman battled on the moon where Superman uncontrollably unleashed an immense blast of heatvision that the Parasite absorbed, causing him to mutate even further into a huge, hulking monster with teeth resembling a leech's. This mutation (Parasite 2.0) again increased Rudy's draining abilities, allowing him to absorb fast-moving objects' inertia as well as making him impervious to telepathic attack to an unknown extent since he could now drain energy through a mental link as he displayed when Dubbilex telepathically attacked him. His extra size and power did have a downside, however; he needed to absorb more energy more frequently in order to stay alive.

Unfortunately for a scientist that was tending Rudy during one of his terms in imprisonment, he was tricked and somehow absorbed into the Parasite. This joining was different from Rudy's others, he actually retained the scientist, Dr. Torval Freeman, as a part of his own mind. This combined intelligence made the Parasite even more menacing.

Because the Parasite can absorb Superman's energy, he is a formidable foe. The Parasite was recruited by Morgan Edge to be part of the second Superman Revenge Squad. Failure followed every one of his encounters with the Man of Steel. After Superman's powers were converted into electrical based ones, the Parasite returned to see what he could absorb from the Man of Steel. However, at this point in time, Superman was not in full control of what was happening with his powers and nearly killed the Parasite. Later, Parasite returned once again, looking to make trouble for Superman but finding himself facing off against Supergirl instead.

At one point, Rudy was contracted to help drain off a being named Strange Visitor's excess electromagnetic energy as she could not fully control it. This exposure to Strange Visitor's power caused the Parasite to mutate again, giving him the ability to fully and permanently retain the intellects of all of his victims and also allowed him to maintain any stolen energy for up to twenty-four hours. Like Torval Freeman, Rudy also absorbed an unknown shapeshifter into his biology, granting him the permanent power to mimic the exact genetic makeup and appearance of his victims.

After he later escaped from S.T.A.R. Labs in the early 2000s, the Parasite began to form a plan to get back at Superman. He began stalking Lois Lane and Jimmy Olsen in an attempt to get to those closest to Superman. The Parasite had taken the form of one of his previous victims, an old man, and was run down in the pandemonium that evening when Lois came to his aide. Not realizing that she was actually in contact with the Parasite, the simple touch was all Rudy needed to get the lowdown on Superman. Rudy was surprised to learn from Lois Superman's secret identity. A new plan formed when he realized how close Superman actually was to Lois; the Parasite decided to take her place and tear him down emotionally by pretending to be a scorned Lois Lane.

Parasite's ruse would probably have worked if he had not had enough of Clark's constant apologies and attempts to get to the bottom of his and Lois' relationship problems. In a fit of rage uncharacteristic of Lois Lane, Rudy punched Clark out of their apartment and into the streets of Metropolis. Shortly after this display, Superman got the Parasite to reveal himself in the guise of Lois Lane. Rudy couldn't handle the fact that anyone other than himself as the Parasite took down the Man of Steel.

Just as the Parasite was about to lay the final blow to an exhausted Superman, Rudy drops, completely crippled by kryptonite poisoning he had drained from Superman, unbeknownst to either Rudy or Clark. Superman finally realized the reason he has felt so weakened recently was because he was being constantly drained by the Parasite and also the victim of the mysterious kryptonite poisoning.

When he asked Rudy how long he had pretended to be Lois, the Parasite related his story to the Man of Steel. In his final moments he tells Superman that he still needed to have contact with Lois once every twenty-four hours to maintain his charade, confirming that she is still alive. He also told him that Lois loves him more deeply than he could ever know. The Parasite died before he could tell Superman where Lois was imprisoned. Lois was soon found alive by Superman and Batman inside a cave the Parasite had used as a hideout.

Lex Luthor, with whom it is implied the Parasite had engaged in amorous, "extramarital" activity while in Lois' form, was infuriated when he learned of the Parasite's schemes. As such, Luthor went to great efforts to obtain the Parasite's remains.
