no if you dont talk at all you get sealed also .if kisame has his sword he wins plus he is rather old so he probably has knowledge about the nin ja tools so if he keeps his mouth shut he wins rather easily he is a beast
Then that would be different and can change both scenarios. While in those forms, the Gin/Kin Bros. want be able to utilize their weapons. They would also be easy targets for Kisame to absorb their chakra with Samehade.well wat about if both brothers were in full 6 tailed form maybe they be 9 tailed form too U_U
