MlGshinobi wrote: That logic is flawed imo, because he attributed the invincibility to the supernatural weapons, that obviously have been around a while. Black zetsu has seen all of shinobi in history including sage of six paths, so him calling invincible is a feat. And the invincibility doesn't just come from the zetsu it comes from the writer too, amazes me people continue to disregard this. But why would he compare it to Hagoromo? At the moment he made that statement, all god-tier ninja were dead and there was no sign they were going to be Edo Tensei. He also didn't just refer to the Sword and Mirror specifically, but rather Itachi's entire setup. Using the Mirror, Susanoo, Mangekyou and Totsuka would make him invincible in his time. And since any potential challengers are long dead, he is for all intents and purposes invincible.
