GIR (Garbage Information Retrieval) is Zim's only companion, GIR is a SIR (Standard Information Retrieval) unit, an Irken standard-issue robot. He was made out of some scraps in a trash bin by The Almighty Tallest. The name "GIR" is a self-applied moniker that is never explained; GIR himself states that he doesn't know why he refers to himself as GIR. GIR differs physically from other SIR units in that his head contains odds-and-ends rather than artificial intelligence hardware. Because of this, GIR displays a wildly erratic personality. He is almost completely irreverent and rarely obeys Zim's commands, variously due to distraction, disinterest and disobedience. GIR disguises himself by wearing a green dog suit which fools most humans, despite looking almost nothing like an Earth dog.
