RX-24 was an RX-Series pilot droid who flew a Star Commuter 2000 from Lothal to Garel five years before the Battle of Yavin. The shuttle was used by the rebels from Lothal in their mission to steal arms from the Galactic Empire. While RX-24 was not necessarily a stickler for the rule that droids could only stand behind the passenger area, he had the authority to enforce it and would do so if there was a complaint. By the time of the First Order–Resistance conflict, Rex worked as a DJ in the cantina of a Unidentified Outer Rim outpost.
