Zetsu solos :sdo:
If you meant the White Zetsu foot soldiers from the War, Hidan soloes like 50 of them easily.
But the original white Zetsu wins. During the Kage Summit his spore Technique completely immobilized both Mifune and Chojuro, who have similar movesets with Hidan.
Those foot soldiers are the same idea. Just zetsu clones.
OT: Zetsu shits and I'd love to debate this one some time.
