Ox was a clone trooper who fought during the Second Battle of Geonosis under Tango Company, led by Lieutenant Trap. He and his company were sent with Padawans Ahsoka Tano and Barriss Offee to deliver supplies to a medical station over Ord Cestus to aid Mace Windu on Dantooine. Not knowing that trooper Sycthe had been infected by brain worms and brought them on the ship, Ox and Edge accompanied Scythe to capture the bridge. Ox and Edge later encountered Ahsoka and Barriss in the mess hall and were knocked out. Right then, Trap and Havoc rushed in to see what was going on. Later after Ox and Edge regained his senses he helped infect Barriss. Ox lived after the brain worms died of the cold and was healed at the medical station.
