R3-S6

"That stubby little backstabber!"

- Ashoka Tano

R2-S6 is a villain from Star wars the clone wars. He appeared in season 1 episode 7. He was the temporary replacment for R2-D2, Anakin Skywalker's droid, who had been captured by General Greivous. Skywalker's Padawan, Ashoka Tano, was convinced R3 was far more advanced than the old R2 unit, but Skywalker had doubts about the droid...

Mission to Vulture claw
Skywalker, Tano, R3, Captain rex and some clones went to the Sepratist Ship, The Vultures Claw to rescue R2 and destroy the place. Many times on this mission R3 made small sabotages, Rex and Skywalker didn't trust him at all. His true colours where revealed when Ashoka was dueling Greivous. Tano was hiding and saw grevious pat the droid's head and say, "R3, what do you have to report?"

R3 vs R2
The detonators where set and the heros had to leave the ship. R3 closed the hanger bay's door's so they couldn't escape. R2 flew to where R3 was and electrocuted him. It appeared R3 had been shut down, and R2 re-opened the hanger bay letting the heroes escape. R3 then awoke and smashed R2 out onto the catwalk outside the ship which was exploding and falling to the planet below. They then started attcking each other with their various slicing tools. R2 then sprayed the floor with oil and smashed R3 onto the edge of the catwalk. R3 used his tow cable to ahnd onto R2 and avoid the fall. R2 used his rocets to set the oil alight. This made the cable R3 was hanging onto weak, so R2 began cutting it with his cutting tool. The cable snapped, and R3 fell of the edge, screamed and then collided with some falling debris that smashed of one of his arms and head off. Skywalker returned in a small ship to rescue R2, then flew away as The Vulture claw exploded.
