GIR is a 2 feet scrap robot. age unknown. GIR's Earth disguise to hide his robot form is a green "mongoose-dog" suit with a zipper on the stomach, and a head with black ears that can be pulled over like a hood. It also includes a small tail that he is inexplicably capable of wagging like an Earth dog. The large eyes blink at times, while at other times, they do not. the mouth will sometimes open when he speaks, other times it stays closed. He eats food and says nonsense. He is ZIM’s assistant.
