Star Wars C-3PO Attack of the Clones 1:6 Scale 12" DiecastProgrammed for etiquette and protocol, "Threepio" was built by a young Anakin Skywalker, and has been a constant companion to astromech droid R2 D2'. In Attack of the Clones, C 3PO left with Anakin and R2 D2 for Geonosis, where he had a bit of a misadventure accidentally swapping heads with a battle droid. C 3PO found he was "quite beside himself" literally on the wrong side of the first battle of the Clone Wars.
