I love this show.

GIR is the deuteragonist of Invader Zim. He also appears in the Netflix movie Invader Zim: Enter the Florpus. 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.


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 The similarities in construction suggest that the components from which he was built came from an out-of-date model of SIR unit.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.


GIR is mainly unstable, reckless, wild, loud, absent-minded, disobedient, enthusiastic, outgoing, goofy, talkative, friendly, happy-go-lucky, energetic and very hyperactive. GIR eats anything, likes to socialize with humans and loves to watch lots of cartoon TV shows, especially The Angry Monkey Show. He often runs around and makes vocalisations. He loves to have fun. GIR is loving and friendly towards everyone.

He can be smart in rare instances such as in "Bad, Bad Rubber Piggy" where he questioned the idea of sending a machine into the past to destroy Dib. His intelligent thoughts were too much for his system to handle and his head exploded.

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.

He also comes up with bizarre ideas which he shares with Zim when in normal mode.


  • "You gonna order a million pizzas, and then I gotta roll around on them pizzas, and that's the story about how I turned into a giant pizza".
  • "I did my best".
  • "I was the turkey all along!"



  • He is voiced by Wasabi Mizuta in the Japanese version, who also voices Doraemon.
  • 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.
  • GIR makes an appearance in the video game Nicktoons MLB where he serves as a playable character and announcer.
  • According to a promo image for Invader Zim: Enter the Florpus, GIR has a heart.
