Zetsu

About:
Zetsu is another member of the Akatsuki. He's a rather odd person who seems to keep to himself. During the extraction of Shukaku he played the role of the watch as well, keeping an eye on the Konoha teams approaching their hideout. Later on it's revealed that Zetsu is a cannibal when the leader tells him to "dispose" of the substitutions used in Itachi and Kisame's fights.

Appearance:
Zetsu's face is half dark and half light. Presumably the darker side of his face is more sadistic and negative while the lighter half is a bit more positive. He also has two large leaf-like things on both sides of his head.
