Images from Star Wars: The Force Awakens have revealed a prevalence of the color red where it didn't used to be — on TIE Fighters, and also on C-3PO, who now sports a bright red arm. How did he get it? That's the story at the heart of Marvel's Star Wars Special: C-3PO, to be released this December.

The comic book, Marvel's second Journey to Star Wars: The Force Awakens, will reunite creators James Robinson and Tony Harris, who enjoyed a critically-acclaimed (and award-winning) collaboration in the 1990s on DC's Starman series, to tell the story of how the beloved protocol droid lost his arm, and found a new one.

"That’s a really exciting part of doing this story," Robinson said in a statement released to the press about the one-off comic book issue. "I saw a photo of C-3PO with his red arm the other day and I thought ‘Wow, I’m the writer who gets to explain that’."

The title follows Marvel's Journey to Star Wars: The Force Awakens — Shattered Empire, a four-issue series written by Greg Rucka with art by Marco Checchetto that debuts in comic book stores and digitally this week, set in the aftermath of the events of 1983's Return of the Jedi.
