Power droid

A power droid is a boxy robot from the Star Wars franchise. Power droids typically had two legs. They served as mobile batteries, capable of powering a variety of machinery and vehicles, and were commonly encountered throughout the galaxy due to their versatility.

Some models of power droid were colloquially referred to as "gonks," after the onomatopoeia of their vocalizations. They were also variously called "box droids" or "dustbin droids."

Notable models

 * EG-6
 * GNK
 * Plunk droid (unholy four-legged variety)

Beyond Star Wars
Power droids became a pop-culture phenomenon on the Internet after the first Star Wars trilogy, including the Usenet "Cult of the Power Droids" of the early 1990s.
