Zetsu, because he doesn't need sight to see(wich makes itachis BIGGEST weapon) he can make 100,000 clones that don't die in one hit and he can move underground. By the time itachi killed the clones his chakra wouldn't be enough, to handle black zetsus wood style.
naruto is way stronger zetsu can't fight
yes yes
no
Zetsu isn't the fighting type so no. He usually acts as a scout and goes to fight scenes to devour the remains of the loser- to leave no traces behind.
Zetsu doesn't fight hardly due to his weak state of being half plant, he is used more as a spy for Akatsuki and disposes of bodies that they don't want found. He is known to split himself apart black side and white side, and create duplicates as an attack.
Zetsu is still alive, for now.
Zetsu is not human; he is a plant-like being created by Kaguya Otsutsuki to serve her. He is composed of two halves, the white Zetsu and the black Zetsu, which represent his different personalities and abilities.
Sasuke killed Zetsu, It's highly debated that Zetsu was pulling off a Bunshin however.
