He's on screen for a fraction of a second so I guarantee you he has at least 2 action figures (one for each outfit with different accessories), a 4 issue Dark Horse mini series explaining how he joined the Rebellion, a Wookieepedia article explaining how he's from Alderaan, had a run in with Boba Fett and helped Han Solo free Chewbacca from Imperial custody years ago. Oh, yes and he or his father will be on next weeks Clone Wars giving Anakin the idea for an advanced TIE fighter.

Have I missed anything?
