The Irken Empire is an aggressive expansionist force headed by the war-like Irken race. The Irkens are bent on galactic conquest and, with the aid of their massive armada, they may actually achieve this goal. The co-ruling emperors of the Irken Empire are the Almighty Tallest, Red and Purple.
The Irken Armada is a vast group of spaceships consisting mostly of Spittle Runners and Shuuvers, escorting the mighty flagship of the armada, The Massive. Whenever an Irken Invader discovers a planet's weakness, they call in the Irken Armada to perform the Organic Sweep. When the planet's inhabitants are killed or enslaved, the Almighty Tallest give the planet a single purpose, such as an intergalactic food court, or a parking structure planet.
