What do we really know about Zetsu?

[Demonthor]

Zetsu is a very mysterious figure that has connections all over the place. Could someone help me figure out what we know for sure about him/it's history and abilities beyond sensory?

I know he is in league with Tobi but beyond that i am confused. Does he have the first hokages cells or was the first hokage's cells used for the Zetsu army and not the creation of the initial thing itself? Please enlighten me, I would greatly appreciate it.

I think just for the army... His white half can be reproduced by an outside chakra source, and he's one with nature... That's all I've got

Uhmmm, Zetsu is a plant

He has a plant on his head.

He's useful for shinobis to test out their new jutsu aka like sasuke did when he escaped from tobis hideout and a great punching bag too also he's useful in making sakura seem useful for once as seen when she noticed something odd about neji i i i mean zetsu and elbowed him to the ground rendering that zetsu clone immobile while she does a post mortem on it to find out why zetsu is a waste of hashiramas dna.
