Darth Oz

Darth Oz was a Human male Sith Lord. He he two apprentices, Lords Rive and Blight, whom he trained separately. Neither apprentice knew of the other's existence, until Lord Oz summoned them both to his Sith Temple on an unnamed desert planet. Lords Blight and Rive were ordered by their master to battle each other to the death; full-fledged Sith status would go to the winner.

There was no winner, however. Darth Rive and Darth Blight were too evenly-matched; both perished in their lightsaber duel. In his frustration, Darth Oz blasted both their corpses with Force lightning.

Behind the scenes
Darth Oz's name is almost certainly taken from Frank Oz, who (ironically) lent his voice to Jedi master Yoda in the canon Star Wars movies.
