Zetsu's head appears to be enveloped in a large venus flytrap, which can also envelop the rest of his body. To further enhance his venus flytrap characteristics, Zetsu is cannibalistic, and as such he is sent to devour the bodies Akatsuki does not want found. This, in addition to his other roles, gives him the function as Akatsuki's hunter-nin, something that is further exercised when he is sent to retrieve the rings of dead Akatsuki members. The right side of Zetsu's body and face is black in color while his left side is white. To go with this, Zetsu seems to have a split personality, as the black half of his face speaks only in katakana while the white side uses kanji and kana. The two halves also seem to converse with each other, and occasionally differ in opinion.
