The GNK-series power droid, also known as the gonk droid, was a type of well-known power droid manufactured by Industrial Automaton that used binary codes. They were often referred to as Gonk droids in imitation of their simple vocalizations. The Alliance to Restore the Republic modified GNK units so they acted as weapons. Once deployed those droids would march slowly across the battlefield, until they collided with an enemy building, and explode.
