R3-S6 was a masculine programmed R3-series astromech droid manufactured by Industrial Automaton on the planet Nubia around the time of the Clone Wars. On his homeworld, R3-S6 was stolen by a group of agents hired by the Confederate General Grievous. They took R3-S6 to the planet Milagro where the astromech droid underwent reprogramming to become a spy for Grievous. The reprogrammed R3-S6 was sold to the Galactic Republic to become Jedi Knight Anakin Skywalker's new astromech droid, as a replacement droid for R2-D2, Skywalker's previous astromech droid. R3-S6 accompanied Skywalker and his Padawan, Ahsoka Tano, as the two Jedi searched for Skywalker's previous astromech droid in the remnants of the Battle of Bothawui in Bothawui space. When the group came across a Trandoshan scavenging freighter in the battle aftermath's debris field, R3-S6, Skywalker, and Tano boarded the vessel to find R2-D2.

After the unsuccessful search aboard the freighter, R3-S6 and Skywalker embarked on a new mission to sweep through suspected Confederate space. The operation was thwarted by Grievous, who tracked Skywalker via the Jedi Knight's starfighter homing beacon, though R3-S6 and Skywalker were rescued by the timely arrival of Tano aboard Skywalker's freighter. Inside the ship, R3-S6 and Tano received a transmission from R2-D2, and Skywalker ordered them to track the signal which led the group to Skytop Station, a Confederate listening post. In the station, Skywalker went to find R2-D2, while R3-S6, Tano, and a group of clone troopers left to destroy the station's reactor core. R3-S6 watched as Grievous confronted Tano's group and attacked Tano, though the Padawan retreated with R3-S6 to a storage room. As the Padawan hid from Grievous in the room for some time, Tano spotted R3-S6 conferring with Grievous and found out the droid's true allegiance. The droid soon left Tano, and found Skywalker in the base's hangar, who also found out that R3-S6 was a spy droid. R3-S6 was destroyed when he was hit by flying debris after a brawl with R2-D2 on a catwalk outside the listening post.
