We all see that the white zetsu carries senju dna & some abilites..but what about the black zetsu? I dont think its a coincidence that the white zetsu (white usually representing good/senju) uses carries senju DNA, while the black zetsu (black usually representing bad/Uchiha) abilities remains a mystery? I bet it has some type of eye techniques.. & its such a coincidence that Kishi fused the white & black zetsu together as ONE character.. resembling Yin/Yang.. & yin/yang is hugely used in asain cultures so I wont be suprised if Kishi wanted to somehow involve that in the manga using zetsu.. Idk though..just came to my thought
And i think tobi is the best zetsu clone which was
created by Madara. When Tobi fighted with Minato
you can see what happens with tobi arm when it was
hitted with rasengan. And how tobi disapears in
the ground. it is just like zetsu is doing. I dont
claim it as truth, but that is my assumption.
