Biography . A Human male nicknamed " Knuckles " was one of one of the many clones of the bounty hunter Jango Fett bred on the planet Kamino to serve in the Grand Army of the Republic . During the Clone Wars , Knuckles served in the Grand Army ' s 182nd Legion , and he earned his nickname for his fascination with hand - to - hand combat . At some point between 22 BBY and 21 BBY , Knuckles participated in a reconnaissance mission to the planet Belgaroth on behalf of the Galactic Republic in order to investigate rumors of the Republic Czerka factory ' s dealings with the Confederacy of Independent Systems . Under the command of Sergeant Marrt , Knuckles and two other clone troopers , Recon and Chatter , landed on the planet and traveled to the factory . Once they reached the facility , Marrt went inside alone to investigate , leaving his squad hidden nearby . Marrt found out that the head of the factory , Tarin , was secretly supplying Reep Tonith of the InterGalactic Banking Clan with illegal FEX - M3 nerve gas grenade s . Taking one of the grenades as evidence , Marrt tried to leave unnoticed but was spotted by Tonith ' s battle droids . The droids opened fire and forced Marrt and the other troopers to fall back to a swamp . The swamp was covered with a fog that prevented the clones from sending a signal to the Republic . A screech was then heard throughout the swamp , and Knuckles surmised that more battle droids had found them . Recon , who was a renowned scout , realized that the sound was emitted by something much bigger than a droid . Suddenly , the native droidbreaker creature emerged from the fog and attacked Recon , throwing him into a tree . As Chatter started frantically firing in the direction of the creature , Knuckles inspected Recon ' s body and , upon finding out that he was dead , reported the fact to Marrt . Soon afterward , Chatter was also killed by the creature . Knuckles then charged the droidbreaker and attacked it with his fists . Realizing that he would not be able to defeat the creature , Knuckles told Marrt to escape . Knuckles was killed , but his sacrifice allowed Marrt to formulate a plan , and the Sergeant managed to kill the droidbreaker by using the stolen nerve gas grenade . Marrt buried Recon , Knuckles , and Chatter under the head of the droidbreaker . Determined to avenge the death of his squad members , Marrt attacked the Czerka factory alone . He suffered heavy injuries but was able to capture Tarin , obtain valuable evidence , and burn the facility to the ground ; although Tonith escaped . Personality and traits . Knuckles was a brawler first and foremost , and he preferred fighting with his bare hands to using blasters . While traveling to the Czerka factory , Chatter told him a joke about a droid , and Knuckles burst out laughing . Knuckles was visibly frightened after he heard the droidbreaker ' s screech and he was shocked by Recon ' s death . Knuckles was willing to sacrifice his life in order to protect Marrt ' s ; and the Sergeant was grateful to him for that , considering his actions to be very brave . The clone trooper had brown hair . Like all clones of Jango Fett , Knuckles stood 1 . 83 meters tall . However , unlike his genetic template , who had naturally brown eyes , Knuckles ' s eyes were blue in color . Behind the scenes .
