Among the Subterrans, the mollocks are a caste of battle-ready warriors noted for their ferocity and fearlessness. After being surgically equipped with prosthetic grinders and drills, the greater tyrants send mollocks to the surface to murder and destroy. Mollock brutes display a wider array of machined replacements geared toward melee confrontations. Berserkers erupt from the ground to startle and flank foes and enter a frenzied trance-like state until no foes remain.
