I want to point out that the "invincibility" comes from Black Zetsu. Considering that pretty much all characters that should beat him, were dead at the time, wouldn't it be more logical to assume Zetsu meant "in the current ninja world"?

Because really, why would he compare it to dead people, it won't change a thing about this fact. Black Zetsu: "well he's invincible, except hashimara could defeat him" Sasuke: well better call Hashirama then" oh wait. yea he's dead, and there's nobody strong enough to Edo Tensei him at full power (again, at that time).

So it raises the question, would Zetsu have made the same comment during the 4th War when all these gods walked the earth?
