Star Wars Rebels season finale will feature one of the most famous Star Wars villian, Darth Vader.
The 13th episode is titled, Fire Across The Galaxy, which will air on 2 March, 2015 on Disney XD.
The season finale picks up from the Rebel Resolve, where the rebels were on a mission to rescue their leader, Kanan Jarrus, from the Galactic Empire.
As entertaining as Disney HD's animated series finale is likely to be, it would feature some classic Trilogy-style action, including a lightsaber battle between Kanan, Ezra and The Inquisitor and a fleet of Star Destroyers.
In the previous episode, fans saw ace pilot Hera talking to a mysterious Fulcrum, whose identity will be revealed in the upcoming episode.
According to a new promo for the season finale: "The mission to save Kanan ignites a Fire Across the Galaxy which shows Kanan fighting Darth Vader in an epic showdown."
The series centres on a rag-tag crew, with cowboy Jedi Kanan, Hera, Ezra, Zeb, Sabine and grumpy old astromech droid Chopper, who are being threatened by new villains, embark on a thrilling adventure.
Star Wars Rebels takes place between Star Wars: Episode III — Revenge of the Sith and Star Wars: Episode IV A New Hope. The series was renewed for a second season in October last year.
The season finale will air on 2 March, at 9pm ET on Disney XD.
