CT-3636, a clone trooper, fought with the 501st Legion in the period just after the conclusion of the Clone Wars. He belonged to an enforcer unit under the command of the Sith Lord Darth Vader, tasked with locating the Jedi Knight Cho'na Bene within the Howling Ruins. After clone trooper CT-3632 told CT-3636 that no movement was observed, CT-3636 asked for a sweep of the surrounding seventy meters. Soon after this, insurgents ambushed the squad, and CT-3636 was shot and killed.
