Re: VS Thread [With Manga Spoilers!]
Kisame vs. the Second
The Second. A Hokage, who alongside the First, put an end to the warring era and established the greatest hidden village. He existed in a era filled with violence and yet was able to rise above it all and create a new era. Sorry, but I can not imagine Kisame winning against him. If anything, it'd be similar to the Naruto vs Gaara fight, where both couldn't stand, but Naruto was the victor.
Kabuto vs. Yamato
Kabuto. In Part I, it was stated that Kabuto was equal to Kakashi. Interestingly enough, when the two had their clash, Kabuto outsmarted Kakashi.
As it's obvious Kakashi has improved, I would think Kabuto had as well. From Yamato's behavior, it seems he's not at Kakashi's level (though he is very powerful). Considering in Part II we haven't seen either Yamato nor Kabuto go all out, I'm just going with what I know.
Neji vs. Sasuke
Sasuke. In Part I, I would have given it to Neji. But that time has passed and Sasuke is beginning to reach the tip of his potential and frankly, by the time all of them are in their prime, the only ninja from Konoha who would be greater than Sasuke is Naruto. (IMO). And none will be greater than Naruto. ^.~ But this could go either way, if Neji got a hit on Sasuke. But could he? Does he have the speed? I'm not sure, so I'm just going with what I know again. XD
Shikamaru vs Kabuto
Ahh, now this is the hardest one yet. It's possible that Kabuto is aware of Shikamaru's shadow abilities (not sure). He did gather information from Konoha for several years, I'm sure he's aware of the Nara Clan's ablilities. Considering that in Part II, it was stated that Kakashi was more intelligent than Shikamaru, and yet in Part I, Kabuto played Kakashi... I would say Kabuto is either as intelligent or even more intelligent than Shikamaru. I'm going to assume that Shikamaru's chakra capacity is lower than Kabuto's..
I'd say that Kabuto is most likely the victor, but Shikamaru is close. It could go either way.
