Invader Zim is an American cartoon series created by Jhonen Vasquez. The show premiered on Nickelodeon on March 30, 2001. The series is about an extraterrestrial named Zim from the planet Irk, and his ongoing mission to conquer and destroy Earth. His various attempts to subjugate and destroy the human race are invariably undermined by some combination of his own ineptitude, his malfunctioning robot servant GIR, and paranormal investigator Dib, one of very few humans attentive enough to be aware of Zim's identity.
Invader Zim was targeted at children in their early teens, and met with critical acclaim, but after the first season, the show's ratings began to decline. Before the second season was completed, Nickelodeon canceled the series, leaving at least 23 episodes and a planned television movie series finale unfinished. The show has maintained a cult following since cancellation with a pilot episode, 46 canon episodes, and at least 17 episodes that were in production at the time of the series' cancellation. On August 19, 2006, all 46 canon episodes have aired on television and been released on DVD. 19 of the episodes are split into two individual stories, each lasting about 12 minutes. There are 8 double-length episodes. All episodes were directed by Steve Ressel except for the pilot which was directed by Jordan Reichek.

Nicktoons: Battle for Volcano IslandEdit
Although none of the Invader Zim characters appeared in Nicktoons: Battle for Volcano Island, there were some cameo's of the show in the game. When you're in the Fort Crabclaw level you can see Zim's Voot Cruiser in the background of the level lying in the bushes. Later as Summit Storm you can see Zim's house floating around in the background. This was probably included to hint to the fact that GIR was playable in Attack of the Toybots and that Zim and Dib were playable in Globs of Doom.
