When attempts on her life were made in 22 BBY and the Jedi Padawan Anakin Skywalker was assigned to protect her, R2-D2 and C-3PO accompanied the two to Geonosis and participated in a battle that started the Clone Wars, a galaxy-wide conflict between the Galactic Republic and the Separatist Confederacy of Independent Systems. Afterwards, R2-D2 directly served the queen, playing a decisive role in liberating Naboo and remaining with Amidala for another ten years, even as she transitioned to the role of senator eight years later. R2-D2 was then recognized before the queen for his work in ensuring the ship's safety. His maintenance work on the ship's hull while it was under fire allowed the queen and her crew to bypass the blockade and flee the besieged world.

In 32 BBY, R2-D2 was serving the Royal Engineers of Naboo aboard Queen Padmé Amidala's royal starship when the Trade Federation blockaded the planet. Like other astromech droids, R2-D2 could walk on two legs or use a third leg to roll across the ground. His bravery, coupled with his many gadgets, played large roles in saving the galaxy time and time again for more than a century. Along with his counterpart, the protocol droid C-3PO, R2-D2 constantly found himself directly involved in pivotal moments of galactic history. Inside of his cylindrical frame were many arms, sensors, and other tools that could be extended to fulfill various needs, such as slicing computers, extinguishing fires, projecting holograms, repairing starships, and flying.

Resourceful and spunky, the droid developed an adventurous personality during his over a century of operation. R2-D2, sometimes spelled Artoo-Detoo and often referred to as Artoo, was an R2-series astromech droid manufactured by Industrial Automaton prior to 32 BBY. " An extremely well put-together little droid." ―Panaka
