GIR is a crazy silver robot. He was built of old parts in the garbage by the Tallest. Before Zim went on his mission, he was given to him as a Standard Information Retreval unit (SIR). However, his name starts with a G. The G could possibly stand for garbage. While he and Zim were flying to Irk, he sang the doom song. He likes waffles, tacos, and many other Earth foods.
Leader: Zim (or the Taco Man)
Also I would like to Credit Invader Scipy for helping for GIR.
