Darth Nihilus
this was one of three surviving Sith Lords, along with Darth Traya and Darth Sion, who survived the Jedi Civil Wars and fled to Malachor V. Darth Nihilus was noted for his ability to literally consume the Force energy of his victims, which was used to sustain his own life energies. It was rumored that he could consume the Force energy of an entire planet. His early history is unclear, and many historians wondered if was was actually a Sith Lord before he arrived on Malachor V. It was believed that he might simply have been a survivor of the Mandalorian Wars who ended up being stranded on Malachor V. What was know for sure was that he was taken in by Darth Traya and trained in the ways of the Sith, until he had attained enough power to earn the title of Darth Nihilus. From the depths of the Trayus Academy, they planned to finally wipe out the Jedi and take control of the galaxy for the Sith. It was Darth Nihilus and his student, Visas Marr, who discovered the existence of The Exile, and Nihilus recognized the threat that the formet Jedi posed to the Sith. He ordered Visas Marr to bring The Exile to him, but she chose to join The Exile rather than betray him. In the meantime, Darth Nihilus led his Sith forces from his flagship, the Ravager, drawing more and more power from worlds that he blasted into ruin. It was on the mission to destroy Telos that Darth Nihilus was finally confronted by The Exile and his team. Although Darth Nihilus managed to stun The Exile, he was unprepared for the devotion of his former pupil, Visas Marr, to the young man. Visas tried to exchange her life for that of The Exile, giving the former Jedi time to recover from his lapse. Together, they confronted Darth Nihilus. The Sith Lord was no match for their combined might, and he fell in battle to them. As he died, Darth Nihilus' body seemed to melt away into nothing.
