C-3PO is a protocol droid build by Anakin Skywalker that feared adventure and preferred etiquette and diplomacy. He and his lifelong droid friend R2-D2 pair up often as unlikely heroes of the Rebellion.
C-3PO was introduced in version 1.0 of the game.
C-3PO unlocks one scene, on the Tatooine Apts level. As a Rebel, he is also actively chased off any Imperial level.
