The Irken armada is poised to conquer the universe, but it would be a lot easier without Invader Zim! Thick-headed, brash and overzealous, Zim has been banished into food service for wrecking the Irken home planet. He's given a second chance to reclaim his lost honor, and is sent on a "secret" mission to conquer the Earth. Now Earth's only hope rests with a young UFO-hunting paranormal enthusiast named Dib, who sees through Zim's disguise and makes it his sole mission to defend our planet from this fiendish menace.
