We know Luke Skywalker, Han Solo and Princess Leia will be more gray and wrinkled in Star Wars: The Force Awakens since the last time we saw them, but how will the past 32 years have treated the franchise's beloved droids?

A new photo of seemingly legitimate Star Wars licensing suggests C-3PO, at least, has undergone a noticeable change.

The Making Star Wars fan site spotted spotted a tweeted photo of a soda can from Mexico that depicts Threepio with a red left arm. It would be easy to write it off as bootleg merchandise, which is occasionally falls short in its attention to detail. However, the website notes the same image of C-3PO, R2-D2 and BB-8 cropped up last month with an officially licensed children's table-and-chair set.

So it certainly seems as if the protocol droid, who's suffered his fair share of mishaps and humiliations -- disassembled and haphazardly reassembled in The Empire Strikes Back, for instance -- may have been forced to cobble together replacement parts. Perhaps, following the fall of the Empire, robotic limbs are difficult to come by.

Directed by J.J. Abrams, "Star Wars: The Force Awakens" opens Dec. 18.
