R2-D2, pronounced Artoo-Detoo and often referred to as Artoo, was an R2-series astromech droid manufactured by Industrial Automaton prior to 32 BBY. Resourceful and spunky, the droid developed an adventurous personality during his many decades of operation. 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. Along with his counterpart, the protocol droid C-3PO, R2-D2 constantly found himself directly involved in pivotal moments of galactic history. His bravery, coupled with his many gadgets, played large roles in saving the multiverse time and time again. Like other astromech droids, R2-D2 could walk on two legs or use a third leg to roll across the ground.
