Invader Zim - Production

Production

Invader Zim was created by comic book writer Jhonen Vasquez who indicated that very little of his writing style was changed, other than restricting language and certain visuals that may not be suitable for children. The biggest difference that he cites is the change from working alone to working with thousands of people at Nickelodeon, calling it an "absolute misery". Apart from a few double-length episodes (including the debut), each episode is a self-contained storyline. Sometimes the occurrences in previous episodes are mentioned but there is no continuing storyline other than the main invasion plot. According to the DVD commentaries, Invader Zim takes place in an alternate universe of its own, with a present-day Earth more technologically advanced than the real Earth. The most common setting of the show is where Zim spends most of his time "infiltrating" the human race at a school (spelled "Skool" in the show), or in his home planning his next "big" takeover. However, towards the end of the show, a larger universe of characters and organizations were beginning to build continuity: Dib's capture and repair of a downed spaceship and use of it to learn more about Zim's race; a resistance to the Irken Empire (The Resisty); an Irken seeking revenge against Zim (Tak); and various other devices which were becoming more and more a part of the show's central mythology.
