"I, Evil Jim, will conquer, the world!"
~ Evil Jim

Evil Jim is an evil copy of the series' titular character Earthworm Jim. He is an evil clone of Jim with a green coloration and a huge desire for evil. He was voiced by Dan Castellaneta (who also voices Jim) in a similar fashion to the Simpsons' Krusty the Clown and Darkwing Duck's Megavolt, both of which were also voiced by Castellaneta.


Evil Jim was made after an accident with a photocopier and toxic waste, creating an evil, twisted version of Jim. This Jim was corrupt to the max, vowing to destroy his original self and then, classically, take over the world. His attempts, however, were all flawed one by one. His first appearance was in "Conqueror Worm", when Jim sees him for the first time and gets himself arrested, thinking it was a case of "Jekyll and Hyde", only to be proven wrong and saved by his sidekick, Peter the Puppy. The more appearances he made, Evil Jim became somewhat more sentimental (because of being the only evil twin in the universe), but also more maniacal.

Evil Jim was created solely for the animated series, but his popularity was enough to make him the main antagonist of the video game "Earthworm Jim: Menace 2 the Galaxy".


Evil Jim's powers are all evil versions of Jim's (for example, the turbine he uses to get around and his raygun), the only difference being that Evil Jim's weapons are all green in color.


Evil Jim is an almost perfect opposite of Jim. He is insanely evil and crazy, while Jim is insanely good and well-spirited. But when Jim thought his evil twin would enjoy losing, as he himself hates to lose, the clone simply replies with "Don't be so literal-minded."
