As we know, the Rinnegan can only be awoken by combining the chakra of the current incarnations of Indra and Asura. However, it's been also stated that the Rinnegan evolves from the Sharingan. The Uchiha were specifically picked by Black Zetsu to carry out his plan because of their hate and because they possessed the Sharingan. If an incarnation of Asura were to implant the DNA of Indra's reincarnation, what would happen to them? Would they awaken the Rinnegan? Would they need to seize a Sharingan first, or specifically the Sharingan of Indra's incarnation? Though I know it's never been directly stated that Indra's incarnation has to be an Uchiha, both we know of have been and Black Zetsu stated it was for that purpose, the Rinnegan. Could Hashirama have awakened the Rinnegan had he reversed roles with Madara? Let me know what you think.
