R3-T2 was an R3-series astromech developed by Industrial Automaton. It was one of the few R3-series astromechs to avoid service on a warship. For many years it was the property of an abusive pirate gang. Sometime during or prior to 0 BBY it escaped, wandering the streets of Mos Eisley, a city on Tatooine. In 0 BBY it was passed in the streets by Luke Skywalker, Obi-Wan Kenobi, R2-D2, and C-3PO.
- R3-T2 shares a body design with R2-D2, but his dome is unique.
