Invader ZIM is an eccentric alien soldier from the planet Irk. He was banished from the Irken Empire after nearly destroying his home planet on an early mission. After begging his superiors, the Almighty Tallest Red and Purple, for another chance, they decide to get rid of him once and for all. They trick him into going on a "secret mission" to an obscure planet at the edge of the universe, a planet with the unlikely name of Earth, in hopes that he'll die along the way. But their trick backfires when ZIM safely reaches Earth and begins his ever-so-subtle conquest of it.
