Invader Zim, Volume 1: Doom, Doom, Doom [DVD]

Comic book artist Jhonen Vasquez's outré sci-fi spoof, which ran on Nicktoons at Night from March 2001 to December 2002, remains the object of a vociferous cult following. Pressure from the fans compelled Nickelodeon to resume production of Invader Zim twice before the show was cancelled permanently. The title character is a zealous, none-too-bright agent from the Irken Empire posing a human boy. Zim imagines he's gathering vital information for the imminent conquest of Earth; the Irken leaders actually sent him here to get rid of him. With the rather spotty assistance of Gir, his robot sidekick disguised as a dog, Zim alternately sneers at humanity and gets himself into trouble. The only person who recognizes Zim as an alien is his UFO-obsessed classmate, Dib.
