C-3PO or See-Threepio is a humanoid robot character from the Star Wars franchise who appears in the original trilogy, the prequel trilogy and the sequel trilogy. Rebuilt 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 all ten Star Wars cinematic films released to date, including Rogue One and the animated The Clone Wars; C-3PO and R2-D2 are the only characters to appear in every film.
