Darth Vader
Darth Vader will appear in Star Wars Rogue One movie Disney/LucasFilm

After making his first appearance in a recently released trailer, Darth Vader in Rogue One: A Star Wars Story has come up in another new look that was revealed via Star Wars trading cards. In this new image, Vader is seen sporting the same armour he had in Star Wars Episode III: Revenge of the Sith.

Vader's signature breathing was heard in one scene in the trailer of Rogue One, but the extent of the iconic villain's role in the movie is still kept under wraps. According to rumours, the villain will be involved in one of the key action sequence.

Also, the synopsis of James Luceno's upcoming novel Catalyst, which serves as a prequel to Rogue One is officially revealed.

Catalyst: A Rogue One Story, which is set for release on November 15th, will shed some light on the creation of the Death Star and who exactly was involved with that. The synopsis released for the book also hinted at Galen Erso (played by Mads Mikkelsen) playing a key role in the Death Star's creation.

Here is the full synopsis released for the book [via starwarsnewsnet.com]:

War is tearing the galaxy apart. For years the Republic and the Separatists have battled across the stars, each building more and more deadly technology in an attempt to win the war. As a member of Chancellor Palpatine's top secret Death Star project, Orson Krennic is determined to develop a superweapon before their enemies can. And an old friend of Krennic's, the brilliant scientist Galen Erso, could be the key.

Galen's energy-focused research has captured the attention of both Krennic and his foes, making the scientist a crucial pawn in the galactic conflict. But after Krennic rescues Galen, his wife, Lyra, and their young daughter, Jyn, from Separatist kidnappers, the Erso family is deeply in Krennic's debt. Krennic then offers Galen an extraordinary opportunity: to continue his scientific studies with every resource put utterly at his disposal. While Galen and Lyra believe that his energy research will be used purely in altruistic ways, Krennic has other plans that will finally make the Death Star a reality. Trapped in their benefactor's tightening grasp, the Ersos must untangle Krennic's web of deception to save themselves and the galaxy itself.
