Almighty Tallest

Almighty Tallests Red and Purple are the main antagonists of Invader Zim. They are the leaders of the Irken Empire that are chosen for their height.In the show, they both despise Zim, a young, ambitious Irken whom they sent to the previously thought to be fake planet "Earth", only to realize that Earth was actually real. They often appear in episodes where they reluctantly check up on Zim and his "mission". They first appeared in "The Nightmare Begins."
