Kids Encyclopedia Facts

Invader Zim is an American animated dark comedy science fiction television series that was created by comic book writer and cartoonist Jhonen Vasquez and aired on Nickelodeon. The series revolves around an extraterrestrial named Zim (voiced by Richard Steven Horvitz) from the planet Irk and his ongoing mission to conquer 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 (Rosearik Rikki Simons) and his nemesis Dib (Andy Berman), one of very few humans not oblivious enough to be unaware of Zim's identity.

Invader Zim premiered on March 30, 2001. The series was targeted at tweens and teens and met with critical acclaim. As the series went on, ratings declined and budgetary issues became more frequent. Before the second season was completed, Nickelodeon canceled the series, leaving several episodes unfinished. The show originally ran on Nickelodeon from 2001 to 2002, with six of the completed second-season episodes initially going unreleased. These episodes were first made available on DVD in 2004 and later made their television debut on the Nicktoons Network in 2006. Despite its early cancellation, due to increasing popularity and above-average merchandise sales, it has been widely regarded as a cult classic.

The series consists of a pilot episode, twenty-seven episodes split into forty-six episode segments, and at least seventeen unfinished episode segments that were in production at the time of the series' cancellation. On December 24, 2011, the pilot episode aired on television for the first time. Thirty-eight episode segments were originally broadcast in pairs, each 12-minute episode segment debuting in the same half-hour. There are eight double-length episodes which run for 24-minutes each. 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.

A television film based on the series, entitled Invader Zim: Enter the Florpus, premiered August 16, 2019 on Netflix.

Meanwhile, Dib has been attempting to salvage/reverse engineer Tak's spaceship (which he acquired in "Tak: The Hideous New Girl") and manages to repair enough of its systems to establish a remote connection of his own to get into Zim's computer and wrestle for control of the Tallest's ship. When the Tallest realize what is going on, they transfer their hacked power-core to the Resisty so their ship is pulled toward Earth. This forces the Resisty to safely evacuate their starship and set it to “shrinky self-destruct” to protect the secrets of its technology from alien thieves.

Zim streaks ahead after making many promises to the students that are crazy but wins them over anyway. Dib counters this by using a cellphone to feed dialogue to a boy who is opposing Zim so he can debate with him properly. Dib's candidate wins the election, but the school faculty brings him to a lab where they (very painfully) remove his individuality and free will, making him nothing more than a mindless figurehead for the oppressive school.
