Backseat Drivers from Beyond the Stars

Invader Zim is an American animated television series that was produced by and aired on Nickelodeon. The series revolves around an extraterrestrial named Zim from the planet Irk and his ongoing mission to conquer and/or destroy a dark and satirical version of the 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 his nemesis Dib, one of very few humans not oblivious enough to be unaware of Zim's identity.

Invader Zim premiered on March 30, 2001. It was targeted at children in their early teens, and met with critical acclaim. However, after the first season the show's ratings began to suffer. Before the second season was completed, Nickelodeon cancelled the series, leaving at least sixteen episodes unfinished. Because of its continued fanbase and above-average DVD sales since cancellation, Invader Zim has been called a cult hit.

The series consists of a pilot episode, 46 episode segments, and at least 17 episodes that were in production at the time of the series' cancellation. As of August 19, 2006, all produced 46 episodes have aired on television and been released on DVD. On December 24, 2011, the pilot episode finally aired on television. 38 episode segments were originally broadcast in pairs, each 12-minute episode segment debuting in the same half-hour. There are eight double-length episodes. This list is ordered by the episode order in the DVD releases, with broadcast dates noted. Almost every episode was directed by Steve Ressel; the only exception is the pilot, which was directed by Jordan Reichek.

In April 2017, Nickelodeon announced that there will be a television film based on the series.

A pilot was produced for Nickelodeon in 1999, featuring Billy West as the voice of Zim. This pilot was never aired during the original run of the series. It was later released as a special feature on the Invader ZIM: Vol 2 - Progressive Stupidity DVD set on August 31, 2004. It eventually made its television debut on Nicktoons on December 24, 2011, as part of their "Nicktoon's Winter Funderland" block.
