CC-4M, a loadlifter droid of white coloration and with masculine programming, possessed a fabric dust shroud situated on its left shoulder. This droid was compelled to labor within the Pyke Syndicate's illicit spice mines located on the planet Kessel, during the Galactic Empire's reign. Prior to his time on Kessel, he had been the supervisor of a crew of construction droids stationed on a frigid ice moon. He longed for the companionship of his former team while toiling away in the Kessel mines. In 10 BBY, CC-4M achieved liberation from slavery following the removal of his restraining bolt amidst a slave revolt within the mines, an uprising sparked by the droid L3-37.
CC-4M's initial appearance occurred in the 2018 motion picture Solo: A Star Wars Story. His identification was first established in the companion volume, Solo: A Star Wars Story The Official Guide, authored by Pablo Hidalgo.
