also if they use straight taijuts(not use chakra0 Kisame can absorb the Kyuubi's chakra because he has unlimited chakra.Well, being brothers, Raikage and Kirabi probably have some killer teamwork. And Naruto and Kisame would have to learn to work together really quickly. But with Naruto pumping out 8 tails chakra and Kisame absorbing Kirabi's cloak and Raikage's lightning armor, that's gonna be a hella strong combination. As soon as Kisame aborbs a good amount of energy, Naruto can jump in and do some serious damage to the lightning brothers.
Wait, as in he is in control of that mode which he has never been shown to do? If so then Kisame isn't even needed and 8 tails Kyuubi will let loose on the cloud brothers.Kisame and Naruto
against
Raikage and Killer Bee
Rules:
Knowledge on opponents
Naruto can control up to 8 tails
Full Health
Open area(flat, no civilians, etc.)
So what if it hasn't been shown, wha are the odds of Naruto and Kisame teaming up? This is all hypothetical.Wait, as in he is in control of that mode which he has never been shown to do? If so then Kisame isn't even needed and 8 tails Kyuubi will let loose on the cloud brothers.
