Takes place on Korriban, flat even terrain. Dooku as of RotS, SI as of the completion of TOR class storyline. Since the SI is a nebulous character personality wise, we will assume that the SI took Dark Side choices and is best known as Darth Nox; we also assume that the SI kept the five spirits under thumb instead of releasing them, reducing his power.
Dooku wins with moderate difficulty. Tyranus simply has superior dueling feats. Lord Kallig dispatching a Dark Council Member isn't that grand considering what Dooku does to Jedi Council Members on a regular basis.
You must be joking. Even Yoda didn't "own" Dooku with the Force. Kallig's feats are TKing a Dark Council Member. Dooku pwnd a Jedi Council Member, and is more than capable of outright destroying the majority of the PT Council with ease.
Yoda is hardly an offensive juggernaut in the Force. In fact I don't think he's ever actually tried to overpower Dooku with the Force. Just blocked his attacks in AotC.
"Anger, fear, aggression! The dark side of The Force are they. ... A Jedi uses The Force for knowledge and defense. Never for attack."- Yoda, Empire Strikes Back.
He's not an offensive Juggernaut? What about throwing landing crafts at each other, or sending Sidious packing with a Force Push. But he didn't try it against Dooku so that's fair. The Inquisitor's greatest feat is defeating a Dark Council member in fair combat. Dooku has pwned powerful Jedi Masters with flicks of his wrist.
End-game SI can deflect lightning with his bare hands (see the Kaggath on Corellia) and TK Thanaton like a ragdoll. I don't see Dooku easily forcing the confrontation to a saber battle, but I concede that in close, Dooku likely dominates.
Well truthfully anyone of not should be able to that. But yes it was an incredible display as he stopped Thanaton's attack and not just some random nobody. However, I would question his ability to do so with Dooku.
By running toward him. Now if Nox is smart about it he would likely be able to force or hold Dooku back but if he decides to engage or just shoot lightning....
Who is Darth Nox and where are his TK feats? Dooku is an enormously talented telekineticist so I'm hesitant to give this guy the nod in that department without ample proof.
