R3S6

R3-S6, also known as "Goldie" or "Stubby," is an R3-series astromech droid assigned to Anakin Skywalker during the Clone Wars to replace his lost astromech droid, R2-D2. Serving as a double agent for the Separatists, R3-S6 often sabotaged Republic missions.

The search for R2
"A gold droid for Gold leader of Gold Squadron."

- Ahsoka Tano, to Anakin Skywalker

Following the loss of R2-D2 during the Battle of Bothawui, R3-S6 was assigned to Jedi General Anakin Skywalker as a replacement. R3, secretly an agent of Separatist leader General Grievous, accompanied Skywalker and his Padawan, Ahsoka Tano, as they searched for R2. In an attempt to gain Skywalker's appreciation for R3, Tano nicknamed the droid "Goldie," pointing out that Skywalker was Gold Leader of Gold Squadron. Despite this, Skywalker still disliked R3, giving him the name "Stubby," as he felt something suspicious about the droid.

While searching the remains of the battle, the trio encountered a Trandoshan scavenging freighter. Believing the vessel may have collected R2, the group boarded, and were welcomed by Gha Nachkt, who claimed R2 was not aboard. Nonetheless, they continued to browse the scavenger's collection. Eventually, they gave up their search and returned to Skywalker's Corellian freighter, the Twilight.

Confederate agent
"Report, Agent R3."

- Grievous

Unbeknownst to Skywalker, R2-D2 was aboard Nachkt's freighter, as the Trandoshan intended to sell the droid to Grievous for the vital information it contained. As Nachkt neared Skytop Station, a Confederate listening post, R2 sent a message to the Twilight, allowing Skywalker to track him. Skywalker, Tano, R3-S6, and a group of clone troopers infiltrated Skytop Station, where Skywalker set off in search of his droid, and the rest set out to destroy the station's reactors. While Tano and the clones were distracted, R3 contacted Grievous, alerting them of the Jedi's presence. The general soon arrived, separating Tano and R3 from the clones. As Tano hid from Grievous, R3 revealed her location, and a brief lightsaber duel ensued before Tano fled. Tano, now aware of R3's allegiance, attempted to reunite with her team in the station's hangar. However, R3 reached them first, proceeding to close the hangar door and activate three vulture droids. Concluding that R3 was a spy, Skywalker ordered the recently found R2-D2 to reopen the doors so they could escape the exploding station via the Twilight.

Duel with R2-D2
R3 followed R2 to the catwalk where the access port was located, and the two astromech droids battled for control of the access port to the hangar doors. A variety of tools were used by both droids in the fight. After R3 bashed into R2 to interrupt his interface with the access port, both droids produced an electro-shock prod and tried to electrocute the other, but as the arcs clashed, the droids were at a stalemate. R2 then sprayed oil at R3 and ignited it with his rocket booster. While R3 was reeling from the flames, R2 tried to bash him off the catwalk but as he began to fall R3 fired his tow cable at R2 to secure himself. R3 dangled helpless for a moment before R2 produced a circular saw to cut the cable, and R3 tumbled from the catwalk before being struck by debris from the falling station and destroyed.
