3PO-series protocol droid

None:

The 3PO-series protocol droid, also known as the 3PO-series protocol unit or 3PO-series droid, was a model of protocol droid produced by Cybot Galactica sometime prior to the Invasion of Naboo. They were equipped with a TranLang III communication module, and as a result were fluent in over 6 million forms of communication. C-3PO was an example of this model, though he was rebuilt out of spare parts. TC-series protocol droids were very similar to 3PO units.
