Beta-379, also known as Pierce, was a clone sergeant who fought during the outbreak of the Clone Wars. He served and fought under his superior officer, ARC-Trooper: Delta-3530 in the 353rd Legion. Towards the years leading up to the Battle of Geonosis, Pierce was one the few Fett-bred clones that Delta-3530 personally selected to train and serve under him in the 353rd Legion. Like Doxx, Typho, Barddock, Aiden Brock, Darnell, and Grayson, Pierce would personally be trained with Delta-ARC training skills, by Gohan.
