Human (Classic)

Humans are the main inhabitants of planet Earth. According to Tetrax, humans are considered a delicacy among most alien species. Dwayne McDuffie confirmed that we should all "wait and see" what a human's ultimate form will be.

Half Humans
Some people that appear human are half alien, and according to Kevin, people with alien ancestry are actually fairly common on Earth, especially among offspring of The Plumbers.
