Geonosians were a winged, semi-insectoid species native to the planet Geonosis that created nests in large, spire-like colonies on their homeworld. The Geonosians would fight on the side of the Confederacy of Independent Systems during the Clone Wars, defending their planet on multiple occasions. After contributing to the construction of the Death Star, they were nearly exterminated by the Galactic Empire. Only a single Geonosian, nicknamed Klik-Klak, survived the Imperial sterilization of their planet, but there was hope during the New Republic Era that some eggs could have also survived, creating hope that a new Geonosian hive could arise.

A caste-based species separated by positions of drones and warriors, Geonosians were born into hives with each led by a queen. The queen laid eggs for the hive, and provided orders to the public leaders of Geonosis. One such queen, Karina the Great, was even able to control sentient beings, including her own kind, via the use of brain worms. It was believed by some that “Karina the Great” was the name assigned to every reigning queen, instead of being the name of one specific individual, but one queen only called herself “Karina” because of her own insanity. No matter the case, Geonosian queens resided underground in the catacombs of Geonosis. From here, they commanded an army’s worth of Geonosian drones. Queens took no more than two years to grow from a small egg to a considerable size.

Drones were capable of becoming warriors if they proved themselves worthy by successfully defeating other drones in an arena. Geonosians of the warrior caste were known as Geonosian warriors. They had wings and a thick exoskeleton, and they were dedicated to warfare. Among Geonosian broods, the alpha was known as the Geonosian Brood Alpha. Geonosians also had two sets of mandibles, outer and inner, which they used to gesture. For example, clicking the outer mandibles twice meant “Work Harder,” and clicking both sets meant “Die.” Geonosians also celebrated Meckgin, a day in which they celebrated the virtues of industry, and believed themselves to be have been blessed by a being known as “the Creator.” Geonosians would get drunk by eating a special fungus which reacted with their stomach fluids to create a body odor which created euphoria.

Naturally industrious and barbaric, they were also known to take upon construction projects from outside parties, as was the case when Baktoid Armor Workshop approached them to design factories for the Trade Federation. Productivity was key to Geonosian society, and if not kept in check with enough tasks, hives could devolve into civil war and result in the deaths of thousands of Geonosians.
