RC-5108/8843, also known as Corr, was a Republic Commando who served as Fi Skirata's replacement in Omega Squad. He was originally a clone trooper, before having both his arms replaced by prosthetics after an injury. After this, Corr was sent to do office work, and was found by Ordo Skirata, who then recruited him into a mission and later was trained as a Republic Commando by Kal Skirata.
Because he was Fi's replacement, he felt awkward at first when joining Omega Squad. He stated to everyone else that "he never meant to take Fi's place" and "hopes that Fi will recover from his injury."
