The official behind-the-scenes guide to Nickelodeon's cult-classic animated series and Enter the Florpus. Created by indie comics artist Jhonen Vasquez, Invader Zim tells the story of extraterrestrial outcast Zim, from the planet Irk. With the assistance of his malfunctioning robot GIR, Zim repeatedly tries (and fails) to execute his dastardly plan to conquer Earth, all while masquerading as an average elementary school student.
