PA-LT4, an A-LT Utility Droid with white and gold plating, belonged to the criminal organization Crimson Dawn during the Galactic Empire's reign. Back in 10 BBY, it functioned as a server, offering refreshments aboard the First Light, Dryden Vos's yacht and the leader of Crimson Dawn, as part of a group of droids. When the ship touched down on the planet Vandor, the droid carried a selection of chilled fruit on the temperature-regulated tray it carried, aiming to stay out of the way. This particular droid model came equipped with two specially designed traction treads.
The 2018 movie Solo: A Star Wars Story marked PA-LT4's debut, with the reference book Solo: A Star Wars Story The Official Guide by Pablo Hidalgo providing its official designation.
