*R2-D2, a three-legged, barrel-shaped utility astromech droid, functions as a sophisticated computer-repair and information retrieval robot. Princess Leia uses his holographic storage ability to hide stolen plans for the Empire's Death Star. Artoo's ability to operate in deep space and interface with such craft as X-Wing fighters, makes him Luke's companion in the Death Star trench. The droid uses a seemingly endless array of gadgets to aid the Rebels. *Source: Back of card
