Irken Empire

The Irken Empire is an aggressive expansionist force headed by the Irken race. The Irkens are bent on galactic conquest and, with the aid of their massive armada, may actually achieve this goal.

The co-rulers of the Irken Empire are a duo known as the Almighty Tallest, although they are figureheads. The ones who hold the real power over the empire are the Control Brains.

When an Irken Invader discovers a planet's weakness, they call in the armada to perform the "Organic Sweep" (They position their ships over the target planet and bombard it with all of their artillery, destroying everyone and everything.). After this, the Almighty Tallest give the planet a (usually singular) purpose.

Fire Rebellion Storyline
The Irken Empire is considered an existential threat to the Multi-Universe due to their goal of galactic conquest and their overall power and size. The Irken Empire has yet to sweep, or even threaten, a world under the Multi-Universal United Republic. However, the Republic is concerned that they will target one of their worlds soon.
