Artoo succeeded in repairing the hyper-drive, thus saving the lives of everyone on board. The ship soon had to stop at Tatooine. There, the ship's crew recovered a new hyperdrive and Artoo befriended the young Anakin Skywalker and C-3PO. Artoo soon helped in the recapture of Naboo. Soon, R2-D2 became an ordinary companion of the now Jedi Knight Anakin Skywalker, helping in the Battle of Geonosis by keeping Padme Amidala alive. At the outbreak of the Clone Wars, R2-D2 served aboard almost very of Anakin Skywalker's Jedi Starfighters, along on countless missions with Anakin, Obi-Wan, and several Jedi, including Ahsoka Tano. At the end of the Clone Wars, and Anakin's transfer to the Dark Side, Artoo and C-3PO eventually fell into the hands of Rebel Alliance's Princess Leia, until her ship was boarded. She inserted the plans of the evil Death Star inside Artoo and sent him to Tatooine. Artoo successfully brought the plans to the now in hiding Obi-Wan Kenobi and Luke Skywalker, son of Anakin.
