GIR

GIR is happy-go-lucky, enthusiastic, energetic, excitable, and extremely hyperactive, and will eat just about anything, regardless of whether it is edible or not. Most of the time he spouts nonsense, but does have a few, short moments of clarity.

The only differences between GIR and regular SIR units are the unique coloration of the luminous parts of GIR's body (teal instead of red, although they do go red when he is in Duty Mode), a different configuration for the eyes, and his cross-hatched mouth. The similarities in construction suggest that the components from which he was built came from an out-of-date model of SIR unit.

GIR's usual Earth disguise consists of a green "mongoose-dog" suit with a zipper on the stomach, and a head 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 sometimes blink while at other times, they do not. Also, the mouth will sometimes open when he speaks, whereas other times it stays closed.
