The Leigun are an inorganic race that has existed for many millennia. The Leigun could easily rival Xenomorphs in their ferocity, able to infest and take over entire planets over a short amount of time. But unlike their organic rivals, the inorganic Leigun can do many things organic races cannot. They can survive in the void of space, grow to enormous sizes, and expel incredible amounts of energy from their bodies to crush their foes. They can also change shape, such as mimicking the appearance of a friendly being in order to stalk and take organic hosts. In general, Leigun are energy parasites, preying on organic creatures for their precious life force. Leigun then process this life force into a potent form of energy that can sustain them for long periods of time.
