A swamp is a bad place for an astromech droid, and R2 quickly found himself submerged in sludge and even swallowed whole by a giant reptile, but fortunately it found him indigestible and spit him out. Meanwhile, R2-D2 went with Luke Skywalker to the swamp planet Dagobah, where Luke was to train with the Jedi Master Yoda. Fortunately, those pieces were found by Chewbacca, the tech-savvy Wookiee copilot of the Millennium Falcon, who was able to restore 3PO to consciousness but didn't have a chance to fully reassemble him. He thought he heard an R2 unit and was looking for another familiar face, but instead he encountered a squad of Imperial stormtroopers and was literally blasted to pieces. When they arrived in Cloud City on the planet Bespin, 3PO wondered away from his friends after encountering another protocol droid. He took serious damage in that battle, and C-3PO even volunteered to donate parts for his repair, but the Rebels, grateful to Luke for destroying the Death Star, did an exceptional job of repairing R2 on their own.Д¬-3PO was mostly an annoyance as the crew of the Falcon had to hide from the Empire and navigate an asteroid field. When Luke volunteered to fly an X-Wing fighter in the attack on the Death Star, R2-D2 performed the same function for him that he had for his father, interfacing with the X-Wing's astromech slot to help the ship fly. Soon after, the droids, Luke, and Obi-Wan escaped Tatooine on board Han Solo's ship, the Millennium Falcon.ДЄfter rescuing Leia from the Death Star, the whole group arrived at Rebel Alliance headquarters on Yavin IV. He succeeded, along with 3PO and Luke, but the Imperial search for the droids led to the murder of Luke's aunt and uncle. R2-D2, however, was determined to fulfill his mission for Princess Leia by finding the exiled Jedi Obi-Wan Kenobi. On the desert planet once again (although 3PO had no memory of his original time there), the droids were captured by Jawas and sold to Owen Lars and his nephew, Luke Skywalker. This one turned out to be a hologram operated by a group of Pit Droids who were secretly running the planet themselves ('Nomad Droids,' season 4). Then R2 and 3PO landed on the planet Balnab, which was also ruled by a dictator. C-3PO introduced them to the concept of democracy, but it only led to more fighting as the droids made their escape. R2-D2 accidentally squashed the tiny despot, to the delight of the other Patitites, who then helped the droids repair their ship. The Patitites brought them before their dictator, Hay-Zu, who considered all off-worlders to be enemies. In one of their strangest adventures, R2-D2 and C-3PO made an emergency landing on the planet Patitite Pattuna, where they were tied up Gulliver-style by the tiny inhabitants. When R2 and 3PO found themselves trapped beneath the planet's surface, they discovered a way to stop the quakes, earning the eternal gratitude of the Aleena people ('Mercy Mission,' season 4).

The droids were heroes in their own right when they were sent to the quake-ridden planet Aleen as a part of a relief effort.
