   This looks like a large insect, its legs swept forward and joined by a wing-like membrane. Its forelegs are large and powerful, though they seem to be designed to pick up objects rather than to fight.

Description

   The savage Gashyrr Wasps of Eldersthine were initially inducted into the Swarm to serve as resource gatherers. Over time they became Drones, engineered with the Larvae's ability to break down their own genetic coding and transform themselves into rudimentary Zerg structures. A transforming Drone needs the Creep to provide nourishment and mass to support its new form. Like the Larvae, Drones are controlled by the Overlords who monitor their progress through a type of instinctive telepathy. Drones are also unusually single-minded about their tasks, diligently working even through raging combat.

Combat
   Drones shy from combat, quickly burrowing into the ground when under attack. This technique allows them to remain concealed from their enemies while regenerating or waiting for reinforcements to arrive.
   Morph (Ex): A Drone may transform into Zerg structures. It must be upon the creep, and the process takes 1d4 hours.
   Skills: Drones have a +4 racial bonus to Hide and Listen checks while underground.
