okay Naruto versus Kirabi(Killer bee).
This is not a straight forward answer in my mind becuase even though 9 tails is better than 8 tails. Naruto i beleive would be taken out long before he could release any of the tails becuase of how n control killer bee is.
If you say killer bee please answer how many tails Naruto would have to have in order to beat him.
(sorry if this is already up if it is just say so and i will delete)
