This little discussed droid pops up at numerous points in the Star Wars films. They are first seen bumbling around the Lars’ farm in A New Hope.
They make a noise as they walk around which is not particularly flattering and as such are also referred to as Gonk Droids.
They are not totally useless though and are used to recharge machinery and vehicles. Disappointingly, the Power Droids tend to feature as background characters.
Character cool factor: 4
Most likely to: waddling around in the backround
Least likely to: getting a lead role in a Star Wars film
