Rudy Jones

"We are Parasite."

- Rudy Jones

Dr. Rudy Jones was a research scientist who became infected with an alien parasite that could absorb the powers and life energy of other beings; this turned Jones into an alien-human hybrid called Parasite.

Infection
Rudy Jones works as a researcher to stop global warming at Thorul Arctic Research Station in Norway. When His team finds a frozen wolf that was oddly emanating heat signatures as if it were alive, he performs an autopsy on it, only to became infected by an alien parasite who infested the animal's tissues, and kill all of his staff.

Back to National City
Rescued by the D.E.O., Jones is taken back to National City, where the parasite start to take him over and begins targeting anti-global warming politicians. Despite Supergirl and Martian Manhunter tried to stop him, eventually he sucks the powers of both, leaving J'onn in critical condition and transforming into a larger and monstrous purple alien-human hybrid called "Parasite".

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

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.

Powers

 * Energy/Power absorption: Rudy was able to absorb the life energy of other beings, leaving withered corpses. After contact with Supergirl, Rudy's 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. His ability was overwhelmed by Plutonium-239, causing him to be painfully disintegrated.

Behind the scenes

 * In the DC comics, Parasite frequently appears as an enemy of Superman, who feeds on energy by absorbing it into his body with his touch, draining all living creatures into husks.
