Irken Empire

The basic goal of the Irken race is total universal conquest. They mostly attain this featwith the aid of the Massive, the flagship of their military and personal vessel of the Almighty Tallest, which aids in universal domination via a sort of final attack called the Organic Sweep. The Irkens institute the Organic sweep when one of their own, an Irken Invader, has successfully infiltrated and taken over a planet they intend to conquer, in order to let the rest of the universe know that planet is now Irken territory. The intelligent inhabitants of the planet are forced to work as slaves like short Irkens while the unintelligent inhabitants are simply killed off. The planet is then given a single purpose. Planet Foodcourtia (which presumably had a name, as well as native inhabitants, before it was conquered) became an intergalactic food court, having various restaurants such as Shloogorgh's Flavor Monster, the planet Vort became Irk's top military research prison, and the planet Blorch became a parking structure planet.

The rest of the universe that know of the Irkens refer to them as bloodthirsty, tyrannical and dictatorial, which may be true to an extent. However, the Almighty Tallest and the Control Brains determine what the Irken population thinks through PAK programming. Considering Irkens bloodthirsty and tyrannical is a matter of perspective, because Irken thoughts are actually programmed. Despite this, they do have a brain capable of independent thought. Irkens do not sleep, though it is not known why.
