Forget Maul vs. Vader!

[Avathar]

THIS would be one of the most interesting duels

Jedi Master Yoda

“Yes, a Jedi's strength flows from the Force. But beware of the dark side. Anger, fear, aggression; the dark side of the Force are they. Easily they flow, quick to join you in a fight. If once you start down the dark path, forever will it dominate your destiny, consume you it will, as it did Obi-Wan's apprentice.”

vs.

Sith Lord Darth Vader

"Don't lecture me, Obi-Wan. I see through the lies of the Jedi. I do not fear the Dark Side as you do. I have brought peace, freedom, justice and security to my new empire!"

(and remember, in this battle, both are at their strongest)

 

[Squall Leonhart]

I voted Yoda.
