C-3PO or See-Threepio is a fictional character in the Star Wars franchise who appears in 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 ten of eleven of the Star Wars films released to date, with the exception of Solo: A Star Wars Story, where the character does not appear. Anthony Daniels is also the only person to be involved in all 11 Star Wars films.
