'Star Wars Rebels'

“Star Wars Rebels” Season 3 is coming and fans of the franchise are, at long last, getting something they’ve dreamed of for many years. In a trailer for Season 3 shown to audiences at Star Wars Celebration in London, it was revealed that Imperial Grand Admiral Thrawn will be joining the fight.

Lars Mikkelson has been added to the voice cast as Thrawn, who will be a key asset to the Imperial forces as they attempt to eliminate the rebellion once and for all.

The character was first introduced in the “Thrawn” trilogy of books written by Timothy Zahn between 1991 and 1993. While Thrawn has popped up in books and audio dramas over the years, he’s never appeared in the animated shows or films. When Disney took over the “Star Wars” universe and put a stop to the extended universe books, declaring them all non-canon, it seemingly put Thrawn out to pasture. Luckily for fans, that’s officially no longer the case. He’s now an official part of the “Star Wars” canon.

What’s more, Zahn is writing a new Thrawn novel, which will release in April 2017.

“You couldn’t have grown up a ‘Star Wars’ fan without encountering Thrawn. I know you guys wanted it and we wanted it too,” Executive Producer Dave Filoni told the audience. “So now you have it. Thrawn’s back.”

Thrawn wasn’t the only revelation made during the “Rebels” panel, where fans also got to watch the Season 3 premiere.

New character looks were also shown off, including Kanan’s (Freddie Prinze Jr.) new mask after being blinded, and a new hairstyle for Sabine (Tiya Sircar). According to Filoni, small tweaks were made to most of the show’s characters, as “Rebels” bridges the visual gap to the movies, as it approaches “Rogue One” in its timeline.

It was also noted that while Ahsoka (Ashley Eckstein) may have been killed in her battle with Darth Vader (James Earl Jones) — the true outcome of the battle is currently unknown — you’ll probably be seeing the character again in some form.

“I’m not going to say in what way, but it’s likely you have not seen the last of Asohka,” Filoni says before jokingly adding, “It could be a cheap out like a flashback. They would hate that, so it probably won’t be that way.”

With so much still to be revealed, “Star Wars Rebels” continues to be one of the most exciting facets of the “Star Wars” universe, expanding the franchise in new ways.

“Star Wars Rebels” Season 3 will premiere in the fall on DisneyXD.
