Almighty Tallests

The Almighty Tallest are the REAL main antagonists in Invader Zim.

Description
The Almighty Tallest are the leaders of the Irken race 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."

If the series would have continued, their hatred towards Zim would have led to their downfall.

Personality
The Red Tallest is very cunning and calculating, tricking Zim into going to Earth in the first place, and the Purple one is rather idiotic. They both love to eat junk food and like sending young Irkens on missions to other planets.
