Droidekas

Droidekas, also known as destroyer droids, were a type of droid used by the Trade Federation in the Star Wars universe. During the Invasion of Naboo and, later, by the Confederacy of Independent Systems during the Clone Wars.

Droidekas were dangerous and deadly, designed to exterminate their adversaries with extreme prejudice. They could transform their shape by curling into a ball and moving up to 75 kilometers per hour across a surface, or stand on three legs and utilize a shield generator while firing at a target.
