*Protocol droid C-3PO always hated space travel. But he and his astromech partner R2-D2 saw many galactic adventures over the years, and shared a good deal of it with at least two generations of Skywalkers.

It was this earlier Skywalker who built Threepio many years earlier before beginning his fateful Jedi training. *Source: Back of card
