C-3PO

C-3PO (See-Threepio) was a 3PO-series protocol droid designed to interact with organics, programmed primarily for etiquette and protocol. Sometimes referred to as Threepio, he was fluent in over six million forms of communication, and developed a fussy and worry-prone personality throughout his many decades of operation. Along with his counterpart, the astromech droid R2-D2, C-3PO constantly found himself directly involved in pivotal moments of galactic history, and aided in saving the galaxy on many occasions.

C-3PO was rebuilt from spare parts by Anakin Skywalker, a human slave who lived in Mos Espa, a city on the Outer Rim world of Tatooine. During the Clone Wars, he would serve the Naboo Senator Padmé Amidala. Shortly after the Clone Wars, C-3PO's memory was erased, though R2-D2's memory was not. C-3PO and R2-D2 were assigned to the Alderaan cruiser Tantive IV, where they served senator Bail Organa for nineteen years, assisting in his fledgling resistance movement against the Galactic Empire. At some point during this time, C-3PO's right leg was fitted with mismatched plating.

C-3PO remained constant companions with R2, and in 0 BBY, the pair became embroiled in the Galactic Civil War when Leia Organa of the Rebel Alliance entrusted them to bring a copy of the Death Star plans to the Jedi Master Obi-Wan Kenobi on Tatooine. After meeting Skywalker's son, Luke and the smuggler Han Solo, the droids helped rescue Princess Leia from the Empire's Death Star. They became directly attached to the three humans, helping them and their rebellion defeat the Empire and restore freedom to the galaxy, most notably when he convinced the Ewoks to aid the Rebels at the Battle of Endor.

Following the Battle of Endor, C-3PO continued serving the Skywalkers and Solo during the time of the New Republic. About thirty years after the events on Endor, C-3PO was still an aide to Organa, who had become a general in the Resistance, a private military group opposed to the First Order, a military junta that emulated the Old Empire. By that time, C-3PO was fitted with a new set of gold plating, which had a more symmetrical design than his previous coverings, with the exception of his head. His new coverings included a third finger joint, and a torso that was not a slim as it used to be. Because of his new plating, he no longer had a mismatched right lower leg. Although, he did end up wearing a red left arm for a very short time to honor his friend 0-MR1, or Omri. By that time, C-3PO's language database had also been updated so that he could understand and communicate in over seven million different forms of communication, including ancient Sith dialects. He would assist Rey in translating Sith writings in order to locate Darth Sidious and the Sith Eternal's fleet, the Final Order, on Exegol, allowing his memory to be wiped in order to carry out the task. However, his friend R2 backed up a large portion of his memories, and after the Resistance defeated Sidious and the Sith Eternal in the Battle of Exegol, his memory was restored.

C-3PO was known for his polite, fastidious, and worry-prone personality. As a droid, he exhibited much loyalty and commitment to his masters and sought to serve them to his best ability. Throughout his operational life, C-3PO worked diligently for several masters including Anakin Skywalker, Padmé Amidala, Bail Organa, and Luke Skywalker. As a protocol droid, C-3PO could communicate in over seven million different forms of communication. This allowed him to communicate with computer systems including those on the Millennium Falcon. Pit droid WAC-47 found C-3PO to be a "handsome fella."

Unlike his best friend and astromech counterpart, R2-D2, C-3PO liked to stick to routine and did not respond well to change. When placed in danger, C-3PO had a tendency to panic as shown on several occasions, including infiltrating a droid foundry on Geonosis and a mission to steal Imperial disruptors on Lothal. Despite his loyalty and commitment, C-3PO was generally unable to lie or to keep secrets due to his programming. In fact, after the Hijacking of the Harbinger, during which Task Force 99 captured him, they remarked to Darth Vader that they were unable to get him to shut up. Despite the droid's talkative nature, he was able to keep Anakin and Padmé's marriage secret. C-3PO's inability to lie came at a disadvantage when he and his companions were captured by Ewoks prior to the Battle of Endor. Due to his general inability to keep secrets, Bail Organa arranged for him to receive a memory wipe in order to preserve the secret of Anakin and Padmé's offspring, Luke and Leia.

Threepio's programming, focused on etiquette and protocol, impacted his personality and limited his behavior in several other ways. On Endor, he found it difficult to impersonate a deity due to his programming, and during the attack on the Resistance fleet, he attempted to leave a mutiny in progress because it was not correct protocol.

C-3PO continued serving Leia Organa in her careers as New Republic senator and subsequently Resistance General. C-3PO managed General Organa's Resistance droid spy network. Despite not being able to run or fight, C-3PO bravely stayed behind to hold back the First Order Agent Terex so that Poe Dameron and the spy droid N1-ZX could flee deeper into the caves. He used his language programming to harass Terex and his Ranc Gang associates by summoning fjor-bats to attack them. C-3PO quipped that he was expendable and could be rebuilt.

C-3PO was a 3PO-series protocol droid, who stood at a height of 1.77 meters and weighed 75 kilograms. He had a masculine programming and had experienced at least two memory wipes throughout his operational life. C-3PO's is covered in golden plating. He has one red arm. As a protocol droid specializing in human and cyborg communications, C-3PO could speak six million different forms of communication, including Ewokese.

By the time of the Cold War, C-3PO's TranLang III communication module had been upgraded, allowing him to speak in seven million forms of communication. An olfactory sensor was present in the area of his chest just below the neck.

After a generation of Imperial rule, New Republic turned its attention to reshaping galactic politics, with member worlds raising their own planetary defense forces as its military was significantly demilitarized and relied on egalitarian policies to remain on friendly terms with neutral star systems and ex-Imperial governors. The New Republic would eventually move some governmental functions back to Coruscant, being designed to handle and administer the galaxy's infrastructure already. Meanwhile, Imperial remnants continued to persist, particularly in the Outer Rim Territories, where activates increased as the prospect of Grand Admiral Thrawn return to the galaxy loomed.
