@WarcoW:
I understand your logic.However, Kaku isnt a swordsman.And Zoro did not beat him in swordsmanship.
Secondly, He doesnt necessarily have to fight a swordsman everytime.Kumadori has something more like a large knife rather than a sword so i would hardly call him a swordsman either.
Are you kidding? Kumadori kept trying to commit Seppuku in order to regain his honor, a very samurai thing to do (well, maybe in Kumadori's case it was taken way into the extreme ^_^). If he isn't a swords man then I don't know who is.
@WarcoW:
And yes, on account of him not breaking through the Tekkai even with his Iron cutting swords, means that he isnt strong enough to take on two CP9 ers at once.
He wasn't able to cut through Lucci's Tekkai while he was in his Zoan form (his most powerful form) not Kaku's. Huge difference. We've seen that there are different levels of Tekkai strength (recall Blueno's Tekkai gou). Therefore it's safe to reason that the stronger you are, the stronger your Tekkai. And besides, it was the first time Zoro encountered such a technique. Who's to say he hasn't already figured out its weakness? If Luffy can so easily analyze Rokushiki techniques, then why not Zoro who you could say is more head smart than Luffy?
Not to mention, it would make the other Straw Hats look lame, especially Luffy (who is much stronger) and Sanji (who is more or less as powerfull) than Zoro, If he gets to take on 2 of them AT ONCE while they didnt.
Also saying Sanji would need Usopp's help to take on Kaku kinda makes him look weaker than even Chopper =\
We all know Zoro is at least the second strongest of the Straw Hats. So we know he's stronger than Sanji Otherwise, all those who is stronger "Zoro or Luffy" One Piece moments would be meaningless (recall the jousting color spread from chapter 387). Having him fight a 2 on 1 would simply just re-affirm how close in strength he is to Luffy and that he is indeed at the very least, second strongest of the Straw Hats.
Luffy will be fighting Lucci who is like twice the strength of Kaku (douriki-wise). So having Zoro do a 2 on 1 doesn't make Luffy look lame. Sanji will be fighting (albeit alongside Usopp) the second strongest of the CP9 Kaku (something usually reserved for Zoro), who has just powered himself up with a DF fruit, making him even stronger (who knows how much stronger?). So no, having only Zoro do a 2 on 1 would not make Sanji look lame.
Id say the chances of something like that happening would be close to zero.
As for the chances of this happening or not, we'll see. But I think the biggest evidence I see for this happening is that fact that they're so perfectly lined up (observe how they're positioned in the spreads) for this sort of match up.
