Star Wars EotE: A New Hope
A devoted, crafty and highly opinionated droid here to save the universe.
R2-D2, pronounced Artoo-Deetoo and often referred to as Artoo, is 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 are 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 finds himself directly involved in pivotal moments of galactic history. His bravery, coupled with his many gadgets, played large roles in saving the galaxy time and time again, though many of his attachments and even some of his memory have corroded beyond use.
Like other astromech droids, R2-D2 can walk on two legs or use a third leg to roll across the ground.
