In my opinion, Revan could kill Marko Ragnos. If you've actualy played Star Wars: Jedi Academy, your character, slaughters Marko Ragnos in his full power. And he's weaker than Revan, in my opinion anyways. Revan was always mopping up any enemy. The character in Jedi Academy, may have had allot to get through, but not more than Revan. Imagine Revan's stress throughout his missions.
