Droideka/Legends

Droidekas, or "Destroyer Droids", are seen in the Star Wars prequel films. These droids can transform-they appear first in a "wheel" state allowing rapid movements and easy storage, then unfold into nasty, insect-like droids with a slow three-legged gait. In their walking state, Destroyer Droids have powerful twin blasters and personal shield generators. They were deployed at Naboo and Geonosis, and are mainly the property of the Trade Federation and The Confederacy of Independent Systems. According to the Expanded Universe, the original design was made by the insectoid people of Colla IV, who were displeased by the limitations of Baktoid Combat Automata's basic battle droids, and chiefly manufactured there. The Trade Federation, and presumably the Confederacy, used trading in rare meats as a way to ease bargaining with the ravenously carnivorous Colicoids, and were able to get special rates on these normally very costly droids. Before the Federations defeat at Naboo, these droids were usually slaved to a central computer, although this technique fell out of favor in the aftermath of said battle.
