This is a real fun character to draw, one from the epic series of Star Wars movies. One of the most beloved characters C-3PO, also spelled See-Threepio, also called Threepio for short, was a protocol droid- a droid specifically designed to interact with organics. C-3PO's TranLang III Communicator module combined with his AA-1 VerboBrain allowed him to be fluent in over six million forms of communication. He was also equipped with over 36 functions. C-3PO was generally seen with his counterpart, R2-D2, a small, wheeled R2-series astromech droid. C-3PO's main function as a protocol droid was to assist with etiquette, customs, and translation so that meetings of different alien cultures ran smoothly. C-3PO loyally served over forty masters. Detesting adventure and space travel, for they often resulted in him coming out in the wrong place in a fight, sometimes losing parts, and then having them reattached, sometimes incorrectly. Together with R2-D2, C-3PO played a vital role in Star Wars galactic history, however lowly he may have thought of himself. Well, that's about it.
