From Steven Melching’s earlier tweet (which has since been deleted), we were led to believe that Captain Rex and the gray-bearded rebel trooper seen on Endor were one in the same. Turns out that is not necessarily the case as Melching took to Twitter to clarify his original tweet which contained a Star Wars Rebels Season 4 character model rendering of Rex (see below) wearing the same helmet as the Endor troopers and a similar type of outfit.

Will Rex eventually be officially announced as that gray-bearded Endor rebel trooper? We shall see. Given what has already been stated/inferred about the possible connection between the two characters, my bet is we’re already far enough down the road to make that conclusion.
