Vader can ragdoll her with TK. Hes an infinitely better duelist, he's far more skilled, he's faster, and his feats are superior across the board. Her illusions apart from affecting Bane (on a nexus), have only affected fodder. Vader DESTROYS her whether its a saber duel or a force battle. Call me when Zannah can collapse cathedrals, crush tie fighters mid flight, telekinetically rip out massive trees, or blow a massive hole in a durasteel door. Zannah would lose to any high tier whether its Revan, Caedus, or Vader
Vader is a better duelist but it will take time for him to penetrate her defenses. Vader is a more skilled and powerful Tker but Zannah has a lot of magnitude behind her TK so I don't think Vader will be able to just go Force Choke, GG. Zannahs illusions will either have 1 of two effects on Vader, they will break him completely by making him remosful for what he did to padme or else they will make him go super rage monster because Zannah used Padme against him, yeno kinda like the time that he was being plagued by visions of Padme and Vader died and willed himself back to life because he was pissed as ****. Then he blew a guy up and survived for days underground.
Yea if Zannahs illusions don't work she is ****ed.
Which is useless as she had to gather energy to use her illusions as she did when she was getting beaten down by Sarro. It cannot be emphasized enough that he only time Zannahs illusions have worked were on force nexuses, beyond that theyve only affected fodder non force sensitives. Vader would either overpower her (He is stronger than Bane), or he can opt to toss her around with his TK. Zannahs got nothing
Yeah, the fight would probably be similar on her end to her fight with Bane initially--except this time her opponent is even stronger and more precise. As displayed in her fight with Sarro, she really can't apply her mind-affecting sorceries whilst being driven to her heels, and attempts could honestly be interrupted via Vader's immensely superior TK.
That being said, Vader's inexperience with Sorcery may prove a disadvantage were she able to apply it against him. Vader likely takes a solid majority, but Zannah can reap some wins.
You guys are severally underestimating Zannah. She was only partially getting her ass handed to her by Bane before pulling out her (nexus) desu ex machina powers. And don't forgot the time she defended herself against the firestorm. Sure, she may have done it sub-consciously and never performed a force feat on a similar level again but it shows her power damnit!
