A clone trooper fought as part of the 501st Legion in the Battle of Umbara, taking orders from Clone Captain CT-7567. Following most of the 501st's participation in the operation, Pong Krell, a Jedi General who was temporarily in charge of the 501st, turned against them. Krell escaped into the Umbaran jungle when the clones launched an assault against him. This clone joined a group of other troopers in chasing after the treasonous Besalisk. He spoke with Captain Rex through a comlink while they were hunting Krell. Krell killed the trooper, but the clones ultimately tracked down and captured Krell.
