Irken

"These Irken bastards came to our planet. I think they're just in time for Organic Sweep or something else."

--Su Ji-Hoon, Coming in Peace

The Irkens are an imperialistic race of green-skinned humanoids from the planet Irk. The basic goal of the Irken race is total universal conquest; they mostly attain this feat with the aid of their vast armada, which aids in planetary destruction (or because they have allies with the Coalition of the Red Star, a planetary change) via a sort of final attack called the Organic Sweep.
