@UltimaDude That's true, but considering that Madara's EMS evolved into a Rinnegan seems to imply that you cannot get it unless you get the Sharingan first unless you were born with the Rinnegan like in Hagoromo's scenario.

@Killman If all of Asura and Indra's chakra magically left Madara and Hashirama's bodies after they died then how did Hagoromo manifest from Madara's body? He said that Asura, Indra, and Kurama's chakras allowed him to appear before the Hokage. That means that Madara's body must have still retained the chakras even after death, which means that Hashirama's would've too.

Also, Hagoromo did not just give Sasuke the Rinnegan. He gave both Naruto and Sasuke half of his chakra meaning they both got Six Paths Chakra, and Naruto combined it with Senjutsu to get Six Paths Senjutsu and augmented it further with all of the tailed beasts' chakra. While Sasuke unlocked a unique Rinnegan and Complete Body - Susanoo earlier than usual. Not to mention that Naruto was still stronger than Sasuke was afterwards anyway. So I don't think any of it equals out, also most importantly, Hagoromo stated that fusing Asura and Indra's chakra together results in the Rinnegan. He didn't say anything about them unlocking Six Paths Senjutsu through it at all.
