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.All-Star Superman #5. DC Comics.
