GIR

"I love this show."

- GIR

GIR is the deuteragonist from the animated television series Invader Zim. He is the robotic assistant/sidekick of the show's main character Zim, and the closest thing he has to a friend, having been constructed from scrap parts and given to Zim by the Almighty Tallest instead of a regular SIR (Standard-issue Information Retrieval unit).

GIR is voiced by Rosearik "Rikki" Simons.

Appearance
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), 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 The similarities in construction suggest that the components from which he was built came from an out-of-date model of SIR unit.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 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 a human dog's. The large eyes sometimes blink while at other times they don't. Also, the mouth will sometimes open when he speaks, whereas other times it stays closed.

He also has a small child disguise with blonde hair and the mouth hanging open so he can see, but it was only used in two episodes.

Personality
GIR is mainly unstable, reckless, wild, loud, absent-minded, outgoing, goofy, talkative, friendly, happy-go-lucky, energetic and hyperactive. GIR eats anything, likes to socialize with humans and loves to watch lots of cartoon TV shows, especially The Angry Monkey Show.

There is another side of his personality that isn't shown as much. He can 'flip out' dramatically, usually when he is controlled by Zim and switched to Duty Mode, causing him to act extremely serious, obedient, aggressive and demanding, such as in the episode GIR Goes Crazy and Stuff. He is quite intelligent when in Duty Mode and his speech patterns aren't nonsensical.

Trivia

 * He is voiced by Wasabi Mizuta in the Japanese version.
 * He plays a main role in three episodes: Invasion of the Idiot Dog Brain, Walk of Doom, and GIR Goes Crazy and Stuff, and plays minor or secondary roles in almost all other episodes.
