R2-D2

R2-D2 was the astromech droid used by Anakin Skywalker during the Clone Wars . He is known to be very adaptive and has saved the General on a number of occasions. Anakin didn't want to clear R2's memory because he valued it too much. He has seen action on tons of different planets.

Clone Wars prelude
R2-D2 accompanied Jedi Padawan Anakin Skywalker, C-3PO, and Padme Amidala to the planet Geonosis. He and C-3PO followed after the humans and entered into the droid factory through the catacombs. R2-D2 used his rockets to fly around, but others such as C-3PO weren't as lucky. He landed on a terminal and helped Padme get out of the situation she was in. He then found his way to the Geonosian Arena, where the a battle was fought. He successfully connected C-3PO's body to his head and they both left the desert planet with Senator Amidala. He was given to Anakin Skywalker by Padme for a wedding gift. That sparked the beginning of R2's career with the Jedi.
