Wait Wait Wait is Zetsu in top 10?

[ImNoOne]

Neither would be able to take down 100k zetsu clones it is too much for them. Only Edo Madara, Naruto, Nagato, Tobi and Kabuto can pull it off. Both 3rd Raikage and Hashirama were killed by a huge army of fodders from one nation. And 100k zetsu clones>>>>> huge army of fodders from one nation

Only that you are forgetting that Hashirama is the source of Zetsu's power. If there is one fit to dispose of Zetsu that one would be the First Hokage.
As for the 3rd Raikage I have to agree. One thing is the eight tails or 10000 for three days straight. 100k zetsus would be too much.
