Voca

Voca was a Human male clone of the bounty hunter Jango Fett. Following the rise of the Galactic Empire, Voca served as a Stormtrooper commander in the 501st Legion, by then under the command of the Sith Lord Darth Vader. Shortly after the disappearance of Admiral Garoche Tarkin, the son of Grand Moff Wilhuff Tarkin, Voca accompanied the Sith and two battalions of the 501st on a mission to locate Tarkin's missing son. During the mission he wore a set of Katarn-class armor distinguished with blue markings. Ultimately, Darth Vader was the only one who survived the assignment; Voca and his stormtroopers were ultimately killed by Atoan insurgents as a result of the treachery of Captain Shale, an Imperial officer who secretly supported Atoa against the New Order of Emperor Palpatine.
