Battle of Kamino Ĭolt and his fellow ARC troopers remained on Kamino. After they had graduated, Colt and his fellow ARC troopers saw off the cadets as they shipped out as soldiers for the Republic. However, he was disappointed by Domino Squad's performance after they had broken various protocols. He was very impressed with Bravo Squad's performance in the Citadel Challenge. Shortly before the Battle of Kamino, he along with the bounty hunter's Bric and El-Les oversaw clone cadets' training.
At an unspecified time period during the Clone Wars, he was promoted to the rank of Clone ARC Commander of the Rancor Battalion. Colt was born on the planet Kamino, as all the clone troopers of the Galactic Republic were and, like all clones, Colt was a genetic copy of the once renowned bounty hunter Jango Fett.
