Suigetsu vs. kisame

[White Zetsu]

Who would win this battle actually tell why

[Kuromaki]

Kisame sucks all of his chakra out, no more turning into water for him.

[Frost ninja]

Yeah basically.
Suigetsu stays solid, Kisame eats his chakra.
Suigetsu goes water, Kisame sucks the chakra out of the water.

[Shikamaru Nara]

Kisame blitzes.

Kisame's water jutsu >>>> Suigetsu's mainly because he's faster, more experienced, and has a wider range. Water dome may work too.

If not Kisame sucks out his chakra.
