Brain worms were a species of parasitic worm from the planet Geonosis which were capable of entering the body of a host and taking control of it[1] and had the potential to control entire societies.[2] During the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems, the Geonosian Queen Karina the Great used brain worms to control a host of undead Geonosians.[1] After Republic forces defeated Karina and her minions, a brain worm managed to infect the clone trooper "Scythe" and used him to infect a number of other clones in Tango Company as well as the Jedi Padawan Barriss Offee onboard the Republic medical frigate TB-73. Jedi Padawan Ahsoka Tano was able to prevent the infection from spreading further by using extremely low temperatures to combat the worms, saving Offee and most of the troopers.[3]
