...And of course, numerous Star Wars Expanded Universe guides say he is one of the Galactic Empire best Dark Jedi with enough power to rival Darth Vader. In fact, he's usually refer as the best student of Palpatine so he's supposedly a cut above the numerous Dark Siders in the Empire like Mara Jade and Jerec. Hell, the radio adaptation of Dark Empire actually made his fight against Luke an actual fight, meaning he could slightly hang against a guy who can fight a being that can move at sublight speeds and is more or less getting closer to that physical force god that can manipulate things similar to freaking black holes.
...Star Wars old expanded lore was ridiculous when accumulating every feat.
But really, Sedriss is practically the Jaime Lannister of Star Wars. You hear how awesome he is but barring one impressive feat he incredibly comes off short.
So...Without additional information and just using Dark Empire he might lose but with all that info he destroys T'Challa?
