AsStar Wars Rebels” Season 4 will be the animated series’ swan song, a lot of theories are now emerging about its ending. Aside from the much-awaited return of Ahsoka Tano, it is also assumed that Captain Rex is at the Battle Of Endor.

Ever since the Clone Captain was seen in the 3D CGI show with a lush white beard, a lot of fans believe that he is also in the decisive battle on the forest moon of Endor. In fact, the show’s writer Steve Melching might have just confirmed this theory with a tweet, but it was later deleted.

Rex and Sant’s similarities

Fans were suspecting that Captain Rex is also the personality behind Nik Sant from the old Expanded Universe.

Sant was a small-scale warrior from the Battle of Endor in “Star Wars: Return of the Jedi,” but his character was deleted when Disney took over of the franchise. When the media company introduced an old, bearded rebel, fans quickly assumed that he is actually the retired Clone Captain.

So, when Steve Melching shared concept art on his Twitter account, his eagle-eyed followers quickly saw his resemblance to Nik Sant. The fandom went into a frenzy, so the writer promptly deleted his post. He later explained that he didn’t see Captain Rex’s similarities to Sant, but eager fans pointed their likeness one-by-one.

Some don’t even want to believe that “Star Wars Rebels” production team cannot see the resemblance, Gizmodo reported.

Another hint of Rex’s appearance

At the recent Star Wars Celebration in Orlando this year, there was another art design revealed at the “Animated Origins and Unexpected Fates" panel that hinted at Captain Rex’s presence.

The panel hosts “Star Wars Rebels” executive producer and co-creator Dave Filoni and Lucasfilm story group team member Pablo Hidalgo shared this image to thousands of event goers. According to the website Dork Side of the Force, the snap just confirmed that Rex is still alive after “Star Wars: Return of the Jedi.” This, too, means that he is with "Han Solo, Princess Leia, Chewbacca," and other surviving Rebels at the Battle of Endor.

He, too, is allegedly going to be seen with new battle gear.

Dork Side of the Force also mentioned this reasoning: "They are the team on Endor" that successfully disabled the "shield generator," which is protecting the second Death Star’s safeguard. When they have disabled its protection, they have effectively destroyed the galactic superweapon that led to the defeat of the Empire.
