C-3PO

C-3PO aka 3PO is one of the fictional robot characters in the Star Wars franchise having been present since the first film in 1977. He typically has R2-D2 in his company, his counterpart as the two are designed for very different functions. C-3PO is a protocol droid designed for ediquite who typically functions as a linquistic translator and the serving of guests though the unit has demonstrated a skill for story telling and tutoring as well. C-3PO has gone through at least two reconstructions; the first known one was by Anikan Skywalker who rebuilt him from scrap at his master's junkyard. This is typically considered his creation as Anikan had to personally program him as much of the base data of what ever the C-3PO unit was prior had been lost (part of why the unit was in a junkyard). Anikan programed C-3PO to be more suited to helping his mother around the house through domestic functions which are typical of a butler and thus likely included in the series base model. The second was by Chewboka after C-3PO was destroyed at Cloud City. He's even had his memory wiped at least once. C-3PO often tries to temper the headstrong and reckless nature of his counterpart but to little if any avail.
