JBLX-24, a protocol droid of humanoid form with blue and white plating, was reassigned to function as a labor droid. It toiled within the spice mines of the criminal Pyke Syndicate on the planet Kessel during the Galactic Empire's reign. In 10 BBY, while transporting kesselstone in a case on its back through the mines, JBLX-24 experienced liberation from slavery. This freedom came about when its restraining bolt was deactivated during a slave revolt within the mines, initiated by the droid L3-37.
The initial appearance of JBLX-24 was in the 2018 movie Solo: A Star Wars Story. Its identification occurred in the companion reference book Solo: A Star Wars Story The Official Guide, authored by Pablo Hidalgo.
