A yet-unfinished droid, C-3PO is being built piece by piece on Tatooine, with parts taken from a variety of sources. Although constructed from used and reconditioned materials, C-3PO is meticulously assembled, following the structure of a standard Cybot Galactica protocol droid model as closely as possible. Most of the necessary parts are bought or traded for in junk shops on Tatooine, while some of the elusive pieces have to be built from scratch. Special requests to a star trader, or even a smuggler, occasionally help to obtain the more complex components. C-3PO is intended as a household servant. In spite of his unfinished state the droid can already perform several of his programmed functions, including translation in a number of languages. A few secondary components are still missing, but most of all C-3PO lacks his outer casing "skin" which will help him blend into human society and meanwhile protect his internal components. As additional pieces are added to the mechanical puzzle, the droid becomes more and more functional. Getting used to his environment takes up most of C-3PO's time, and he still has a lot to incorporate into his memory banks. But he is learning fast, and events will soon start him down the path to his destiny.
