Designed as a protocol droid, C-3PO's main programming function is to interact with human society. He is an interpreter fluent in over six million galactic languages, specializing in the areas of etiquette and translation - especially important during diplomatic missions. To aid in these tasks, he is equipped with microwave and olfactory sensors, photoreceptors, vocabulator speech units, energy transducers and broad-band antenna receivers. He was programmed with an elegant, human sounding voice, but more often than not C-3PO is heard whining and bickering with his companion, the astromech droid R2-D2.
C-3PO was once a simple interpreter aboard the transport ship Tantine IV, but a twist of fate made him one of the most wanted droids in the galaxy and a reluctant but loyal hero in the Rebel Alliance's struggle against the Empire. When her transport was attacked by Darth Vader, Princess Leia Organa hid secret technical readouts for the Empire's new Death Star in the memory banks of C-3PO's companion R2-D2. The two droids then jettisoned from the ship in an escape pod, setting about the chain of events that brought Luke Skywalker, Han Solo and Obi-Wan Kenobi into the Rebel Alliance and ultimately led to the destruction of the Empire's ultimate Battle Station.
