CC-6592, nicknamed Kiaras, was a clone marshal commander in the 455th Battle Battalion during the second year of the Clone Wars. He fought in a number of battles during the war, including the Battle of Coruscant. Kiaras was one of the few clone commanders who did not kill his Jedi General—the General in question was Jedi Master Draki—when Order 66 was issued. Kiaras was later killed by fellow clone trooper and Palpatine loyalist CT-9845, who also killed Draki.
