The commando was the leader of Ion Team, which was a detachment of 22nd Air Combat Wing. He and his squad were deployed on Murkhana in 19 BBY, where they captured a human by the name of Idis. A member of the Vibroblade Brigade, he assisted the Corporate Alliance in protecting the crime-driven world of Murkhana. After the capture, the team was sent to a medical center where a shield generator was located, a shield that protected the city from the artillery. Ras, Climber, and Jedi General Roan Shryne had attacked a group of twelve mercenaries, and Climber was almost killed. An attacking mercenary almost killed Climber, but after borrow Shryne's lightsaber, he was able to impale the merc.
After their mission, Climber and the rest of the clones received Order 66, the order to execute the Jedi. Unlike most clones, Climber and Ion Team did not obey the order, as they thought it to be a Separatist trick. The Commander there, Salvo, was preparing an ambush for the Jedi, which the commandos countered, giving the Jedi time to escape. Darth Vader tracked them down, he killed Ras and Ion Team's comm specialist. Climber and Trace retreated into the forest. He ordered the 501st Legion to hunt them down. During their search, Vader killed Shryne and Jedi Bol Chatak, allowing Jedi Padawan Olee Starstone to escape. After killing Chatak, a Shock trooper informed Darth Vader that they had captured Climber and Trace and the two would be put in prison.
