Buzz was a clone trooper squad leader who served in the Grand Army of the Republic during the Clone Wars. During the Second Battle of Geonosis, he went with Jedi Master Luminara Unduli to search for and capture Poggle the Lesser to take him into Republic custody. They were able to track him down to a temple on their speeders, but unbeknownst to them, the temple was crawling with brain worms. While scouting the temple, Buzz was killed by an undead Geonosian infected with a brain worm. His nickname came from the "buzzing" sound of a running Z-6.
Buzz had Phase I clone trooper armor that was customized with the green markings of the 41st Elite Corps in addition to other personalized details on his helmet. He was equipped with a Z-6 rotary blaster cannon.
