Idk maybe im missing something but Kisame seems like a bit of a joke to me. Despite him being proclaimed as top tier shinobi with tailed-beast chakra and over the top physical strength he seems to take alot of L's. In fact he gets killed 3 times (granted the first fight was a less than half powered representation of him and the 2nd fight was a Zetsu switcharo towards the end). And whats funny is that all times despite his awesome chakra reserves and superior physical strength and endurance he gets put out by physical attacks every time (Gai, A & Bee, Naruto, Gai again). I know the 2nd probably isnt as physically powerful as the others mentioned but Kisame's show history is stack of loses with 0 wins. I dont see this figth being much different
