individuals, he gains their abilities for a limited period of time until he "runs out of life-energy" and must seek a new victim to "feed on". He is shown to have a heightened sense of perception that allows him to detect the life force and power within other beings. While drawing the energy of ordinary humans is almost instantaneous, it takes a notably longer time in the case of immensely powerful beings, which gives the victim more time to react and free themselves from the Parasite's grip. Following an encounter with the Strange Visitor, however, the Parasite's powers were enhanced and enable him to retain the energy he takes for longer as well as granting Jones the ability to shapeshift; he can now physically morph into his victims right down to their DNA, being able to access their memories, gain their natural abilities, and mimic their voices. The Parasite's biggest weakness is that he also absorbs the weaknesses of his victims and cannot counter such susceptibilities even when he has other abilities that should do so; when he absorbed both Superman and Livewire's powers, he retained the latter's vulnerability to water despite possessing the former's near-invulnerability. The Parasite also maintains Superman's weaknesses, like kryptonite, even when the Parasite in addition already absorbed the powers of non-Kryptonians. Other versions All-Star Superman An alternate version of the Parasite appeared in DC Comics' All-Star Superman #5 as an antagonist in the main subplot. He passes by Clark Kent who is interviewing Lex Luthor, a prisoner on Death Row at the 'Stryker's Island' prison. Clark is surprised to see the Parasite, and the entity feeds on Superman's ambient energy. This provides enough power for the Parasite to go on a murderous rampage. The sheer amount of energy causes the Parasite to evolve into little more than a body and a mouth. Clark uses subterfuge and his strength to ultimately defeat the creature. Lex believes his attempts actually helped. Crossovers The Parasite was one of the main characters in the second Marvel/DC crossover between Spider-Man and Superman. In this story, he was recruited by Doctor Doom as an agent in Doom's latest plan to conquer the world by wiping out all power sources but his own fusion reactor. Doom claimed that he needed the Parasite to function as an invincible bodyguard, capturing the Hulk and Wonder Woman and giving the Parasite a harness that would
