In Ahsoka episode 7, C-3PO makes a triumphant return, marking the droid’s most significant appearance in live-action Star Wars in several years. In this episode, Ahsoka takes some time to explore Hera Syndulla’s New Republic story, and it’s in this context that Threepio is brought in, not just as an enjoyable cameo but also as something of a rescuer for the situation.
With Senator Hamato Xiono vehemently opposing Hera’s actions, particularly her claims about Grand Admiral Thrawn’s return and the resurgence of the Imperial Remnant, the responsibility fell on the protocol droid to set things straight. Acting under the orders of Senator Leia Organa, C-3PO’s mission was to persuade the New Republic Senate that Hera’s actions had her full endorsement. It’s worth noting that Anthony Daniels reprised his iconic role as C-3PO in Ahsoka, a character he first portrayed in the original Star Wars film in 1977.
