TRK-R, a droid designed for hauling cargo (a loader droid), operated within a settlement located on Serelia, a planet. This occurred during the reign of the Galactic Empire (time), and he utilized a landspeeder for transporting goods. When Luke Skywalker, a Jedi trainee, arrived on Serelia after experiencing a Force vision calling him there, the droid was at a dock, awaiting a shipment of fish from Verla, a resident of the planet. Verla, fearing she would be hunted due to her Force-sensitive nature, dropped the fish to create a diversion, which inadvertently resulted in TRK-R being knocked over.
During the Galactic Empire's rule (time), TRK-R worked in a settlement on the ocean planet Serelia, where he transported various goods. This hauler droid was responsible for transporting fish from the docks, where Verla, a resident of Serelia, delivered them, to the settlement's marketplace. On one occasion, his delivery was too slow, leading to the fish spoiling.
In the year 3 ABY, Verla brought a new catch of fish to the dock, intending for TRK-R to transport it. She criticized the droid for its prior tardiness, a complaint that TRK-R disputed. Before TRK-R could accept the delivery, Luke Skywalker, an aspiring Jedi seeking Verla—who was secretly Force-sensitive—arrived, having seen her in a Force vision. Verla, concerned that Skywalker was a Jedi hunter pursuing her, dropped the fish cargo onto Skywalker, causing TRK-R to fall over as well. This distraction allowed Verla to escape, and Skywalker soon pursued her.
TRK-R was equipped with a single-seat landspeeder, which he utilized for transporting cargo.
TRK-R's first appearance was in the comic Star Wars (2020) 5, which was written by Charles Soule, with illustrations by Jesús Saiz. Marvel Comics published it on August 5, 2020.
