"We are Parasite."
—Rudy Jones[src]

Dr. Rudy Jones (died November 2016) was a research scientist who became infected with an Angon alien parasite that could absorb the powers and life energy of other beings; this turned Jones into an alien-human hybrid called Parasite. Jones was killed when Supergirl used plutonium from a nuclear power plant to "overload" him. In 2017, Mr. Mxyzptlk used a Parasite illusion to attack National City.

Years later, Parasite was briefly resurrected by Lex Luthor on Earth-Prime to help him battle Supergirl and her team, but eventually he lost and was killed again.


Original multiverse


Rudy Jones worked as a researcher to stop climate change at the Thorul Arctic Research Station in Svalbard, Norway. In November 2016, his team found a frozen wolf that was oddly emanating heat signatures as if it was alive despite having been killed over 4,000 years ago. Jones began to perform an autopsy on the wold, only to become infected by an Angon alien parasite, which had infested the animal's tissues. The parasite took over Jones' body and proceeded to kill all of his coworkers.[1]

Back to National City

Supergirl fight Parasite.

Rescued by the D.E.O., Jones was taken back to National City, where the parasite began taking over and lead to him targeting anti-global warming politicians. Supergirl and Martian Manhunter arrived and attempted to try and stop him, though Jones drained the powers of both heroes, leaving J'onn in critical condition. As a result, Jones transformed into a larger and monstrous purple alien-human hybrid called "Parasite".

However, Mon-El and Guardian teamed-up to fight against Parasite, who was eventually beaten by Supergirl by using plutonium from a nuclear power plant, completely obliterating him.[1]

Reality Warp

When Mr. Mxyzptlk came to Earth, he conjured up Parasite to once again wreak havoc on the streets of National City to show off his powers to Kara.[2]

New multiverse

Lex Luthor used video footage of Parasite to make a commercial for the D.E.O..[3]

During a fight with the Superfriends, Lex Luthor used the Fifth Dimensional magic of the Allstone Totems to resurrect Parasite as his ally. He fought Alex Danvers but his body exploded, killing him once again.[4]


"You can't stop us. You can't stop what we're changing into. This planet is being destroyed by the human race, which lives only to suck the life from it. Like parasites. Only we can save it."
—Rudy Jones to Supergirl and Alex Danvers[src]

It was unknown what Rudy's personality was like before he became infected by an angry alien parasite, but after being infected, Rudy became cold, cruel and ruthless, he was also unreasonable and unstable to the point of being delusional. Rudy had zeal to avoid the climatic change and as Parasite he has targeted climate change deniers.

Powers and abilities


"The organism seems to be absorbing my red blood cells, rewriting my DNA into something new. We're not two distinct beings any longer. We've become one. One greater than the sum of its parts."
—Rudy Jones following his infection[src]
  • Energy/Power absorption: Rudy was able to absorb the life energy of other beings, leaving withered corpses. After contact with Supergirl, Rudy gained her Kryptonian physical abilities and later, the physical abilities of the Martian Manhunter, which mutated him into a monster. Unlike humans, both Supergirl and Martian Manhunter were able to survive his absorption of their power, though each of them were left unconscious in a withered state and the latter was unable to recover on his own without a blood transfusion from M'gann M'orzz.[1]
    • Invulnerability: Rudy became invulnerable after gaining Supergirl's powers. Despite being shot at multiple times by Alex Danvers, the bullets deflected off his body.
    • Super strength: Rudy was strong enough to crush a gun with his hands. After his transformation, he could lift Mon-El by his head with just one hand and was able to lift a car over his head.
      • Super leaping: Rudy could jump several stories in the air on a single bound. He used this power to escape from D.E.O. agents shooting at him and during his fight with Guardian.


  • High-level intellect/Expert scientist: As a scientist, Rudy was highly intelligent and had enough knowledge of genetics to realize that the alien parasite was altering his physiology.


  • Plutonium-239: This substance was able to overwhelm Rudy's life energy-absorbing powers and causing his body to disintegrate; killing him.
