12. Darth Bane
A favorite amongst Star Wars fanatics, Darth Bane isn’t just a badass Sith, he’s a badass Sith-murdering Sith! Yes, see, this megalomaniacal force of evil got sick and tired of disagreements among his Sith brothers and sisters, and got it in his mind that the Sith would be stronger if it was streamlined. In a masterful plot that went off flawlessly, Bane first manipulated the Sith into attacking the Jedi, knowing that it would cause tremendous losses on either side. Once the battle came to a close, Bane then detonated a “thought bomb,” which took out all remaining Siths in the area. Best part??? No one ever found out he was responsible!
