People are clamoring to see the story of the anti-hero in theaters, Fox has picked up on this with their stories of Venom and Sinister Six; yes its a straight villain movie but bare with me. Disney should continue this by producing Star Wars spin off movies of something other than the Skywalker story line. They should start with
Darth Revan. He played pivotal roles as both a Jedi Knight and as a Dark Lord of the Sith in the Mandalorian Wars! He defeated the Mandalorian Leader, where he and another Jedi Malak discovered a mysterious Sith influence on the war, upon their investigation they discovered a new Sith Empire and they were turned to the dark side!! After this Revan used his extensive knowledge of the Republic"s military and he started the Jedi Civil War. He captured and tortured many Jedi and converted them to the Dark side. Eventually Malak begun to resent his master and this lead to a duel between the two that lead to Malak losing his Jaw but gaining more hatred towards his master every day. The Jedi eventually set a trap for Revan and Malak that led to Malak turning on his master and attacking Revan's ship. Revan was captured by the Jedi Order who then converted him back to the light. The story of this movie will directly set up a movie about the creator of the Rule of two and the Sith's version of the Chosen One. .
Darth Bane. He was raised by a poor miner in the outer rim, one day he got on to a fight with his drunk father, later that same night he envisioned his father dying by picturing a giant hand squeezing his heart. The next day his father was dead, he escaped off the planet and joined up with the Sith Brotherhood of Darkness. He was eventually recognized as a force sensitive and was taken to the Sith Academy. He quickly became one of the best students in the academy, even disobeying his teachers and delving into the archives of the ancient Sith. He even traveled off world where he located a holocron that had been created by the Sith Lord Darth Revan millennia ago. Bane spent some time studying the holocron. The knowledge he gained from this holocron validated his view that the Brotherhood needed to be destroyed for the Sith to conquer the Jedi. So that's what he set out to do. He managed to create a Thought bomb and convinced the Sith Commander to use it in the war against the jedi. The Sith went deep in to a cave where all but 100 Jedi followed them However, the Jedi were unable to stop the Sith from detonating the thought bomb, which killed all the Force-sensitives in the cave. Several kilometers away, Bane sensed the bomb's detonation, and since the remainder of the Jedi were unaware of Banes existence the Jedi believed that all the Sith had died in that cave, yet the most powerfull of them all still remained.
