Zerg

The Swarm is a race of xenomorphic "hyper-evolutionary" superorganisms; they are the overriding antagonists of the StarCraft series. Unlike the and the, the zerg are not "tool-makers", lacking technological inclination; instead, they "force-evolve" genetic traits by directed mutation in order to match such technology. Operating as a hive mind-linked 'chain of command', the zerg strive for genetic perfection by assimilating the unique genetic adaptations of "worthy" races into their own, creating numerous different strains of zerg. They are named "the Swarm" per their ability to rapidly create strains, and the relentless assaults they employ to overwhelm their foes.
