CX-1, also known as Sniper CloneX, was a clone assassin during the Imperial Era. After failing to assassinate Senator Avi Singh, CX-1 was captured by the Clone Underground. As the Underground members had prevented CX-1 from committing suicide, another clone assassin, CX-2, was deployed to their base on Teth to terminate CX-1. As a result of the assassin's mission, CX-1 was successfully killed.
As a clone of the human Jango Fett, CX-1 had black hair, tan skin, and wore black armor.
