Humans are a typically disregarded species of bipedal sapients living on the "dirt ball" called Earth. In the Invader Zim universe, humans are technologically more advanced, but less intelligent than the humans in real life.
BiologyHumans (Homo sapiens) are a mammalian species originating from the planet Earth. They are closely related to monkeys - another, more primitive species indigenous to Earth. The average adult human is about as tall as one of the Almighty Tallest, as seen by Zim's height in relation to the Irken leaders and to adult humans, but not as lean and much more muscular. Humans are omnivorous, and will eat both plant-based and meat-based foods.
Humans have a poor sense of hearing but a very developed sense of vision. Humans are able to see the entire visible spectrum of light, most notably the color red, which very few animals of Earth are able to distinguish. However, human eyesight are prone to a variety of problems such as old age, blindness, far-sightedness or near-sightedness, but they compensate by wearing glass lenses that help their sight called "glasses", such as the one that Dib wears. Human eyes will zero in on motion, and are able to see well in both sunlight and moonlight, but not in water or fog. Although technically omnivores, humans possess many features of Earth's carnivores, such as eyes set in the front of head that will track motion, and four pointed canine teeth.
Humans are very adaptable, able to survive with only one kidney and lung (normally having two of each), and have been able to adapt to nearly every environment and situation.
Earth is home to a number of cultures and societies, all "vastly inferior to the Irken Empire". Each has its own views on just about everything there is to have a viewpoint about.
