5 Reasons Why It Doesn't Matter How C-3PO Got His Red Arm In Star Wars: The Force Awakens

4. The Arm Change Wasn't Always Meant For C-3PO

While the red arm trick would seemingly only work on everyone's favourite prissy protocol droid, that's not actually the case; it was almost applied to a different character completely - early concept art showed Chewbacca with a robotic arm,

Chewie is, of course, another hero where the passage of time is an issue; he may be an organic, but Wookiee life-span is so long (he was shoehorned into Revenge Of The Sith, lest you forget) that he won't age in the same discernible way. In the end, the injury was decided against, possibly because the movie itself also saw his arm injured or that a robot hand would be a little too like Luke and undercut that important element.

Chewie if anything looked more trim in The Force Awakens than he did in the originals. And you know what? I'd rather have a comic that explains that.
