Sure looks that way! Last month an image of C-3PO, BB-8 and R2-D2 was spotted on some children’s furniture and it showed that for some reason C-3PO has a new red arm. Another image was found this week on a soda can in Mexico and again it shows C3PO with a red arm.
Did something happen to C-3PO after “Return Of The Jedi”? Or could something have occurred during “The Force Awakens”? Does Tony Stark lend one of Iron Man’s gauntlets to C3PO? We’ll soon find out in almost 6 months!
