Water Release: Tate Eboshi

After using his Hydrification Technique to merge with a liquid source, Suigetsu can form a giant wave that resembles a demon-like fish. Suigetsu can use this form to battle larger opponents, or he can use it to shield allies from attack. Though it was strong enough to physically push back Killer B in his Tailed Beast Mode, it was not strong enough to withstand a point-blank range Tailed Beast Ball, but rendered Suigetsu unconscious soon afterwards, causing him to fall into a jelly-like state.
