The Geonosians are an insectoid species native to the planet Geonosis. Geonosians reside in hive colonies in organic-looking spires. All Geonosians have a hard exoskeleton, elongated faces, multi-jointed limbs, and speak in a strange language.
Geonosis (as seen in Star Wars Episode II: Attack of the Clones) is a barren rocky world home to thousands of factories geared towards mechanical construction. Many of the Galaxy's biggest manufacturing concerns hold contracts with the Geonosians.
In Geonosian society, there are two main types of Geonosian: the wingless drones that mostly work as laborers, and the winged aristocrat, which includes royal warriors serving as scouts and providing security to the hive. They look down on their wingless cousins. Geonosians do not have a standing military, although they do arm themselves with sonic blasters and static pikes. They instead use their droid foundries to build armies for corporate interests wealthy enough to afford them,entities such as the Trade Federation and the Techno Union.
Poggle the Lesser was a Geonosian who appeared in Episode II and oversaw the production of battle droids for the Trade Federation and later provided the bulk of the troops for the Confederacy of Independent Systems. He was decapitated by Darth Vader on Mustafar in Star Wars Episode III: Revenge of the Sith|.
In the video game Star Wars Battlefront II, the player must fight a Geonosian named Gizor Delso who is trying to use the droid factories on Mustafar to create his own army.
Geonosians make an unique appearance in Lego Star Wars: The Video Game, appearing with one of two weapons (either their characteristic sonic blaster or a normal blaster rifle) randomly, beyond the player's contriol.
In Star Wars: The Clone Wars, it is revealed that the Geonosian Queen Karina the Great uses a kind of "brain worm" to ensure the loyalty of other Geonosians. This mind control exists even after the host's death, although the "Geonosian zombies" have pure white eyes.
