(Tales of the Old Republic) Revan -vs- Darth Sidious (Revenge of the Sith)

Revan was able to counter his mental domination. Were he unable to do that the fight would have ended the same as it did the first 2 times he tried to take on Vitiate (which it did anyway, lol).

Sidious is weak and pathetic he couldn't even face his master in a real fight he killed him in his sleep. Revan was far more superior than Sidious he's the only person that found clarity between light and dark.

Treachery was the Sith way, hence why Malak turned on Revan.
