 * "Will Materialisation" is a Yin—Yang Release technique. It can produce black rods as well as living beings like Black Zetsu, meaning they are made out of the same material in different forms.

BeyondRed wrote: The reason Madara and Obito could create rods without the Rinnegan is because they both had Hashirama's cells, or the power of Uchiha and Senju in one. Here i disagree. I think the Statue is a second source of Black Rods. It seems that the Rods are able to multiply (Pains with Rods embedded could make more rods). If Gedo were embedded with Black Rods by either Madara or Hagoromo for better control, it could conceivably make more.
