Sm Naruto i thought, if Kisame try to absorb Naruto's Chakra like when he fought against Killer Bee. He would be turn into Frog like Pain's Preta Path. But it would be a hard battle.
Naruto takes this easy i think. No, don't misjudge. Kisame is powerful but he counts a lot on his ability of stealing chakras with Samehada so he could easily get surprised. Against Naruto SM it will be over.
Best win for Naruto is frog Katas or special toad techniques like Pa and Ma's Frog Call which paralyses the enemy by screaming at them or their genjutsu. Things that aren't just simple chakra attacks.
