Zetsu (ゼツ, Zetsu) is a member of Akatsuki and one of Obito Uchiha's most loyal subordinates. The black half is known as Black Zetsu (黒ゼツ, Kuro-Zetsu), while the white half was known as White Zetsu (白ゼツ, Shiro-Zetsu).
Zetsu is easily distinguished by the two large venus fly-trap like extensions that envelop his head and upper body, giving him a plant-like appearance. When his extensions are open and his head is visible, it is revealed that Zetsu has short green hair, yellow eyes, and that his body has two different coloured halves. His left side is completely white, while the right side is almost entirely black. The black colour does not cover his black half's entire body, as it only extends partially down his leg, which was originally his white half's right leg. Under his Akatsuki cloak, Zetsu wears blue pants and sandals. He also has both legs wrapped in bandages, which hide the area where his right leg's black colouring merges with his white foot.
Unlike White Zetsu, who possesses human-like facial features and a proper eye, Black Zetsu shows no visible orifices at all and only his iris is visible. Black Zetsu also has white dots along the edges of his body where the two halves meet; these are not flat markings, but rather protrude from his body, like little white bumps. White Zetsu also has unusually rounded teeth. In the anime, his fingernails are painted pink and his toenails, as seen at his début, are blue. In the manga, however, Zetsu is often depicted without fingernails. He also wears his Akatsuki ring on his right little finger.
When the two halves split apart, the plant-like extensions split and hang from the waists of both. Their clothes also split in half along with them, leaving each with one pant leg or half of an Akatsuki mantle, should they be wearing it. When they are emerging from the ground, their plant-like extensions surround the two halves in a circular pattern. The two have also demonstrated the ability to grow appendages to substitute for their missing half when split. Sometime after splitting, the two halves seemingly discarded their torn clothing.
