Zetsu has not died yet.
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.
March 18th ^----Kisame's birthday. I don't know when Zetsu's birthday is, though. :c
naruto is way stronger zetsu can't fight
Zetsu likes pie,but only human flavor.
Kishimoto Masashi (author) had originally planned for the akatsuki to be a group of monsters and each character represented something (zetsu = Plant) zetsu was one of them. But he changed the idea of the akatsuki, and he like Zetsu so much he decided to keep him.
Zetsu's birthday is not officially mentioned in the Naruto series.
