Lord Scourge is a powerful, high-ranking Sith soldier in the burgeoning Sith Empire. As a loyal servant to The Emperor, he is asked to root out assassins attempting to kill Darth Nyriss, a powerful Sith Lord and  a member of The Emperor's closest circle. However, he quickly realises that the situation is far more complex than he realises: Nyriss is leading a coup against The Emperor. As The Emperor's subordinate, Scourge is caught in a moral dilemma, and has to decide where his allegiances lie: with his master The Emperor, or the clever and dangerous Nyriss. As the film progresses, Scourge becomes increasingly disillusioned with the Sith, and becomes more and more of an ally to the Jedi Revan and Meetra Surik. Scourge also has a reputation as a strong warrior, which often results in him being sent on dangerous, combat-heavy missions.

Scourge speaks with a hard, sneering tone that occasionally (especially towards the end of the film) turns softer and more vulnerable.
