what happen to white & spiral zetsu?

[Devauzamaki]

i mean they never got killed. Once madara casted MT that was the last time they were shown.

OG White Zetsu's been dead but as for the clone and Guruguru who knows. They'll probably turn into trees or something

 

[Sakuto]

They're about as useful to the plot as the poop they dream of taking in IT. XD

Kishi erase them using his eraser
