Something that never made any sense to me is that Obito never awakened the Rinnegan in his right eye. I know he already had one in his left, but that one was a transplant. So why didn't Obito awaken it in his right eye? I know that he's not an Indra reincarnation, but I wouldn't think that would matter, considering that it has nothing to do with being Indra or Asura, but only that you have the same power as the Sage of Six Paths, which was Six Paths Chakra.
Madara awakened the Rinnegan because he had his own Indra Chakra and then got the Asura Chakra from Hashirama, which made Hagoromo's Chakra.
And then Sasuke got it straight from Hagoromo himself when he also got the Moon mark...
But the thing is, both of those came because they either received or synthesized Six Paths Chakra. It still required Six Paths Chakra to awaken. But that being said, Obito should have awakened the Rinnegan because it was stated that the power of the Sage of Six Paths was the same as the Ten-Tails, and the Ten-Tails was inside of Obito. So why would he not receive the Rinnegan in his right eye?
I theorize that it simply is because he already had a Rinnegan, even if it was pilfered, especially considering that Sasuke also awakened the Rinnegan, but only did so in one eye, though one could theorize that his Rinnegan was fundamentally different, and likely a lot closer to the Rinne-Sharingan, as it appearently had the ability to dispel the Infinite Tsukuyomi, a genjutsu only capable of being cast by a Rinne-Sharingan (Not to mention, many times, the difference between a Rinnegan and a Rinne-Sharingan are blurred). But at this point, all I'm doing is shooting into the dark. I wanna know what you all think. Why did Obito not awaken a Rinnegan in his right eye?
