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.
During the Clone Wars, the Geonosians were part of a Confederate plot on Rishi involving the material exonium. A Geonosian colony was established on a moon. By the time antiques dealer Antron Bach went into hiding on the moon, the colony had long been abandoned.
Pehk was a Geonosian hunter who gained notoriety for being the first person to headbutt a gundark. However, he was hired by Doctor Aphra for the hunt on the world of X3-299-11. Aphra wanted to be rescued from the Shadowfang Beast, but Pehk was caught in a tractor beam trap. After monster hunters Winloss and Nokk were hired by Aphra and arrived, Pehk was killed by the creature.
