Tasuxeda wrote: Not necessarily if just Indra and Asura chakra was enough (...) The point of that was that Madara didn't just awaken a Rinnegan. He truly obtained Hagoromo's power (Pre-jinchuriki). Besides, the rinnegan isn't just a mixture of Ashura and Indra chakra, but a synergy. I likened it to the Ten Tails because it was made from 10 components that in terms of powers and abilities were incomparable to the final creature. E.g. TSB's. MehNameIsJeff wrote: my question was how Hagoromo acquired it just like that and what was the point of it splitting as well as a side-theory that if you get Hagoromo's Chakra you'd also get Sharingan abilities No. The Sharingan has different powers, like Genjutsu, analysis and tracking.

Hagoromo obtained it simply because it's the power he got from his mother. And that power split could be for various reasons. As Kaguya was the only one with power, any man she loved would've been a mundane man. And so, their power would quickly dilute. Alternatively, one could say that the power specialized more and more. Sharingan and Byakugan are simply the smallest unit of a KKG that still makes up a KKG, dilute it more and no power manifests. LegionZero wrote: Rinnegan has Sharingan abilities but it also adds a bunch more powers. And yes you need a Sharingan and Hagoromo's chakra. No one with a Rinnegan did so without having a Sharingan. Also the Rimmegan cannot be shut off. It doesn't, not really. The Rinnegan isn't seen casting Genjutsu nor does it seem to possess the tracking and analysis of the Sharingan. (i agree on the "can't be shut off". Edo Tensei has a cosmetic component so he probably just hid it with his understanding of ET.)

Secondly, no the Sharingan isn't needed. Kabuto fell for selection bias. Black Zetsu makes no mention of the Sharingan or specifically the Uchiha as being necessary. Apparently getting the transmigrants to cooperate enough to care yet hostile enough to obtain the other's power was difficult. Zetsu eventually saw Madara and knew he could do it (since he grew up with Hashirama as a child and so deeply cared, but also was deeply disillusioned). Sasuke was only the second to obtain the Rinnegan, and he got it from the Sage who seemed entirely happy to enforce this split of body/eyes.
