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.

Appearance and Biology
Main article: Irken Biology

Irkens bear a similarity to the humans' archetypal concept of aliens as "little green men" - they have light green skin, sport a pair of angular antennae atop their hairless heads, and have solid-colored eyes (usually ruby). They are generally somewhat short in comparison to humans, usually approximately three to five feet tall. A unique aspect of Irken biology is the PAK device that is attached to every Irken's spine at birth, and serves not only as an ever-present Swiss Army knife, but also a backup brain.
