First let's lay down a few restrictions for this fight:
For the purpose of this fight, let's say Kabuto managed to seal Karama away so he can not interfere with this fight( because we all know Tailed Beast Naruto and Chakra Mode Naruto would tip the scale in Naruto's favor)
And let's say Kabuto does not have access to draw on the DNA of all those other sound ninja who's techs he used against Itachi (because frankly, it's not really his Sage skills but the skills of those he collected and incorperated into his own body)
Both however start in Sage Mode.
Who do you think would win this one?
