So, he could activate rinnegan in one of his eyes without sharingan?

@AnubhavGoel, I don't think you exacly need a Sharingan to activate a Rinnegan, you just need both chakras of Hagoromo's sons or his.

@AkiraMahisaseru so according to that logic even Naruto should have awakened the Rinnegan. Rinnegan can only be achieved if one possesses Sharingan.

@MilapJhumkhawala, good point. I forgot all about Naruto. I guess you do need the Sharingan...

@MilapJhumkhawala You are At least mostly right, but the one thing that throws this all off is the one and only comment on what power naruto got from the sage of six paths, Specifically given my Madara "so one obtained the Senjutsu of the six paths". So Naruto obtained a new Sage mode, Meaning it is possible he did not actually get six paths chakra, and the mark was simply a way to use Planetary Devistation at no cost.

<p>He sealed the Izanagi in his eye before the battle meaning that if he died it would activate and bring him back, so in theory he could have used his old Sharingan before he gained the eternal mangekyo, after all we saw Danzo do that having a sharingan in his arm to sacrifice rather than the one he had in his head. So why can't madara have done the same.</p>

<p>So, Madara had eternal mangekyo Sharingan which he never after Izanagi.
Thus, he could have Rinnegan in both his eyes.</p>

This answer doesn't really validate the statement of having two Rinnegan. It does not even state anything about Izanagi either. This particular extract is about the sight restoration after excess usage of the Sharingan, which leads to the deterioration of the eyes.

<p>Did Madara use Izanagi or Izanami and if yes then how did he have two Rinnegans? If someone uses Izanagi their sharingan gets destroyed right? If he used Izanagi then he should have only one sharingan left and then that evolved into Rinnengan. How does he have two Rinnengans?</p>

He used the Izanagi to cheat death... I think his Sharingans just evolved into the Rinnegan.

Izanagi in same way takes away ordinary mangekyo Sharingan.

So, Madara had eternal mangekyo Sharingan which he never after Izanagi.
