GIR is the insane, hyperactive robotic assistant of Zim and the closest thing the incompetent Irken has to a friend, having been constructed from scrap parts and given to Zim by the Almighty Tallest just before it was handed to Zim, instead of a regular SIR (Standard-issue Information Retrieval Unit). GIR was assigned as a robot servant to Zim, an alien tasked with taking over Earth. Immediately upon his introduction, it becomes clear that GIR is unhelpful, annoying, and erratic.
