Star Wars: 10 Greatest Sith Lords You'll Never Forget

4. Darth Nihilus

Nihilus reigned as Sith Lord during the ere of Strife after the Jedi Civil war. Nihilus survived the activation of the Mass Shadow Generator weapon that engulfed the planet Malachor V with a Mass Shadow. Nihilus should have been killed, but the shadow changed him entirely: he became a wound in the force, an affliction that caused him to crave force energy. He was found by Darth Traya who offered him the chance to sate his hunger, accepted her offer and together along with Darth Sion they formed the Sith Triumvirate. Eventually Nihilus and Sion decided to betray their master, Sion restrained Traya while Nihilus sapped her of her force energy.

Nihilus's affliction continued to worsen to the point he had to encase his spirit within his mask and armour. To feed his never ending hunger Nihilus went on a Jedi purge nearly destroying the order entirely. On the verge of extinction the Jedi had to deal with the threat Nihilus posed. In the end Nihilus's hunger led to his demise, he arrived at Telos V believing it was rich with Jedi force-users.

All of this was a ploy set up by a coalition of Jedi and Mandolorians who ambushed Nihilus on his flagship "The Ravager". In the end Nihilus's physical form was destroyed but the armour that contained his spirit was taken back to the Sith homeworled of Korriban for burial.
