C-3PO

C-3PO (/ˌsiːˈθriːpioʊ/) or See-Threepio is a humanoid robot character in the Star Wars franchise who appears in every movie of the original trilogy, the prequel trilogy and the sequel trilogy. Built by Anakin Skywalker, C-3PO was designed as a protocol droid intended to assist in etiquette, customs, and translation, boasting that he is "fluent in over six million forms of communication". Along with his astromech droid counterpart and friend R2-D2, C-3PO provides comic relief within the narrative structure of the films, and serves as a foil. Anthony Daniels has portrayed the character in eleven of the twelve theatrical Star Wars films released to date, with the exception of Solo: A Star Wars Story, where the character does not appear.

Despite his oblivious nature, C-3PO has played a pivotal role in the galaxy's history, appearing under the service of Shmi Skywalker, the Lars homestead, Padmé Amidala, Bail Organa, Raymus Antilles, Luke Skywalker, Jabba the Hutt, and Leia Organa. In the majority of depictions, C-3PO's physical appearance is primarily a polished gold plating with a silver plated right leg (from knee joint to ankle), although its appearance varies throughout the films; including the absence of metal coverings in The Phantom Menace, a dull copper plating in Attack of the Clones, and a red left arm in The Force Awakens. C-3PO also appears frequently in both canon and Star Wars Legends continuities of novels, comic books, and video games, and was a protagonist in the animated television series Droids.
