Evil Earth was a clone of the original Earth, created by Evil Jimmy using Jimmy's Flux-field Duplicator. It is said to not be an exact copy of Earth, as it's darker in appearance since it's made of some dark matter where everyone acts contrary to their alternate selves thanks to Evil Jimmy's use of a Dark Matter Power Chip. Its only appearance is in the episode "The Trouble with Clones" and by the end of the episode it got trapped into the Dark Matter Dimension due to evil Jimmy breaking the power chip before it could fade into oblivion.
- On Evil Earth, Evil Sheen likes Robo-Fiend, Ultra Lord's arch nemesis, rather than Ultra Lord himself. Ironically, he's still wearing an Ultra Lord shirt.
- Being kind, including saying thank you and compliments, is a sign of disrespect, just like being rude and insulting is on Earth.
