Zetsu has not been fetured in ANY Naruto fighting game to date for lack of Jutsu and he hasn't relly even fought in the series, yet
So far no. btu he might be in future clash of ninja games. The farthest clash of ninja 3 got in the akatsuki is Hidan and Kakuzu. sorry :)
he is not in it
Allied ninja fighting Zetsu clones
naruto is way stronger zetsu can't fight
Yes, Zetsu is a medical ninja but you don't see him do it though.
Sorry but first of all, you can't get zetsui, as he is not available in NSCNR 3. Second of all, Tobi isn't in the game niether, so why would he have that move named like that if Toby isn't in there yet?
no
This happened in Naruto Shippuden Chapter 678, Black Zetsu Betrays Madara.
Sasuke killed Zetsu, It's highly debated that Zetsu was pulling off a Bunshin however.
Zetsu's birthday is not officially mentioned in the Naruto series.
