CC-8/349, known as Four-Nine, served as a clone trooper captain throughout the duration of the Clone Wars. He was in command of a platoon composed of heavy assault troopers. Upon their arrival on the designated planet, Jedi General Mace Windu gave instructions to him and his soldiers to defend against any militia assaults directed at Haruun Kal.
Subsequently, he received directives to safeguard the Balawai officer Lorz Geptun from any potential danger while Geptun was in the process of sending the codes necessary to disable the attack protocols of the droid starfighters. Initially, Four-Nine voiced his opposition to Mace's instruction to employ proton grenades against the control bunker's entrance, expressing his belief that other clone troopers, civilians, and their Korun comrades were still alive inside. Mace clarified that everyone inside had perished, with the exception of the Akk Guards, Kar Vastor, and Depa Billaba. When Four-Nine volunteered to lead his troopers into the bunker ahead of others, Mace declined his offer, stating that the clones would be outmatched by the Korunnai Force-users. Windu's assessment proved accurate, as a significant number of clones fell victim to the Akk Guards' attacks. Four-Nine was among the 24 clone troopers who died during the battle for the control bunker.
