There is a lot of confusion about how madara got his rinnegan out there so I want to clear it up.
He got it without the senju dna because it is the next step for the sharingan evolution.
He did get hashi's dna during his fight and before HIS death with him. Madara clearly states he unlocked the rinnegan SHORTLY BEFORE his death. It doesn't say anywhere he did not die and that he experimented on it, NOWHERE. Madara and Izuna were twins FOR A REASON. Kishi doesn't just make random facts about them. Everything about the characters are there for plot no jutsu. Madara and Izuna were twins so that kishi could write how Madara took Izuna's place inside the coffin. There is no way Izuna died but Madara did. Izuna IS tobi taking care of Madara's plan. Thats how it is bro.
