Evil Earthling

The Evil Earthlings are a race of evil Human clones from planet "Evil Earth". They came into being when Jimmy Neutron's clone "Evil Jimmy" made a clone of the entire Earth.

Biology
Being clones of Humans, Evil Earthlings are presumably identical to Humans in terms of physiology, and remain externally identical.

Culture and society
On the surface, Evil Earthling architecture and general aesthetics remain identical to Earth's, although darker in color, partially due to the perpetually dark skies of Evil Earth. Due to their evil nature, Evil Earthlings constantly insult each other and act rudely, and showing kindness is seen as extremely offensive among Evil Earthlings, even if said act of kindness involves saving their lives. While appearing to be in anarchy, there appears to be some form of law on the planet, still enforced by uniformed police officers, although the laws are twisted and corrupt, with officers arresting anyone who acts good. Additionally, health inspections for restaurants on Evil Earth do not rank an establishment by cleanliness, but rather, by how contaminated it is, with the dirtiest establishments passing the inspections.

As they are copies of Humans, each Evil Earthling has a counterpart on Earth, and their personalities are inverted from their Human counterparts.
