The original Drone organisms were initially inducted into the Swarm to serve as resource gatherers. Engineered with the Larvae’s ability to break down their own genetic code, drones can transform themselves into rudimentary Zerg structures. These structures house and nourish larva awaiting their metamorphosis, hold and sequence collected genetic samples, facilitate restructuring of strains and guiding the evolution of the swarm, and serve as mobile defensive structures for a hive or other important locations. A mutating Drone needs creep to provide nourishment and biomass to support its new form. Like Larvae, Drones are controlled by the Overlords, who monitor their progress through a type of instinctive telepathy. Drones are single-minded about their tasks, diligently working even in the face of raging combat and the possible destruction of the Hive
