Originally posted by SunRazerTenebrous is implied to have been more powerful than Plagueis when he died so yeah.
Revan stomps Tenebrous but his successor Plagueis defeats Revan?Even if the gap between Plagueis and Tenebrous were as large as between Sidious and Plagueis (which it isn't), that still wouldn't remotely be the case.
On the other hand Revan is described as no match for Vitiate.
At the Rishi conference, I recall the Wrath / Hero stating that they should let Revan do what he plans to do, but then Marr states that even Revan cannot defeat Vitiate. Wrath / Hero adopts Marr's stance for the rest of the game and later tells Revan that personally. Marr's understanding of Revan or Vitiate seems to purely be based on the legends of the two. For one, he seems convinced Vitiate is a galaxy-buster without exception. And two, he's never seen peak Revan - or him at all.
I disagree. Revan handled all of Vitiate's lightning to the point where he physically "tanked" (in the sense he didn't die) the rest (and with additional Jedi healing, was up on his feet in a minute). In SoR, where his body is fueled by his willpower, I can see Revan completely overcoming Vitiate's assault and pressing the charge further.
Hardly.
He beat his telepathic assault with... balance in the Force(?) or whatever stupid power that was. He deflected Vitiate's lightning bolts with his lightsaber and reflected one right back at him. Then he absorbed the majority of Vitiate's lightning and survived the excess, healing himself from all that damage and was ready for another exchange.
He was certainly losing, but he did not get 'shit on'.
But he would have died. Point is all we should expect from SOR Revan is to last a bit longer, then also die.
This is of course without factoring in Vitiate fighting intelligently, if he had just conjured a storm in the first place much like he did against the TOR B-team, Revan might never have even gotten in range.
His powers intensified after his death, he went from losing to four Imp protags to handling two far stronger strike teams back-to-back whilst controlling his ritual. Dark Revan became the anti-Vitiate, utterly obsessed with defeating the Emperor. He's going to be far more dangerous than in the novel.
