Episode IV: A New Hope
(in order of appearance)
This is the golden droid who appears in the opening scenes of the film. He is known as a "protocool droid," specializing in governtment functions, and, as he loves to let you know, "human-cyborg relations." Threepio is a main character in all the movies filmed.
R2-D2, also known as Artoo, is an astromech droid, specially designed for starship repairs. Astromechs are frequently paired with protocool droids, so that their language of bleeps and whistles can be translated for humans. Artoo is one of the heroes of the movies, whose help at just the right moment repeatedly gets his human friends out of sticky situations.
