The Irken armada is poised to conquer the universe, but it would be a lot easier without Invader Zim! Thickheaded, brash, and overzealous, Zim has wrecked Irken plans for the last time. Seizing the opportunity to rid themselves of this nuisance forever, they send Zim on a "secret" mission to a planet far away on the edge of the universe-Earth. Now Earth's only hope rests with a young UFO-hunting paranormal enthusiast named Dib.
