I'd like to thank everybody for their participation! I enjoy reading the comments and the predictions for the events to come. Please do not feel shy, please feel free to participate! Do not hesitate to write something down, it doesn't have to be much. it is supposed to be whatever you think. as for me, I just brainstormed another idea, let me share it with you! You heard this here first!
Madara and the Rinnegan
this is perhaps what got me interested in the upcoming events, what is Madara planning to do and how does the Rinnegan come into the picture? as we may know, Madara needed Nagato to use a technique for his sake and now that Nagato is dead, he may not have that chance. however, not too long ago, Madara revealed that he wanted to take out the Rinnegan:
"I need to be ready for war... this is a good chance to take out the Rinnegan."
note that Madara talks about himself, stating that he needs to prepare for war. it seems that Madara, himself, intends to fight and demonstrate his strength on the battlefield. Madara also states that this is a good chance to take out the Rinnegan, implying that he already has a pair. if we put these two things together, it seems that Madara already has the Rinnegan and wants to test it out in battle just like a new weapon is tested out in battle.
Transplanting the Rinnegan
this incident seems to have confused quite a bit of people, everyone is wondering how could an Uchiha transplant the Rinnegan when the Uchiha bear the Sharingan? I guess not too many people remember that the elder son of Rikudou Sennin, the first Uchiha, had the Rinnegan.
"The Elder brother was born with the Sennin's 'eyes'... the strength of chakra"
now that we know that the first Uchiha had the Rinnegan and that the Uchiha clan actually had the Rinnegan early on in its history, a transplant of eyes is certainly possible. the Uchiha clan also inherited the chakra of Rikudou Sennin, so they wouldn't have much problems wielding its massive powers. the Rinnegan is the original doujutsu of the Uchiha clan, so it was a kekkai genkai since it was genetically passed down. furthermore, Madara stated that the Rinnegan can decode more of the Uchiha tablet than the Mangekyou, which in turn can decode more than the regular Sharingan. if the Uchiha tablet can be fully decoded by the Rinnegan, obviously the first few generations of the Uchiha clan had the Rinnegan. eventually the Rinnegan became the Sharingan and we have yet to find out how.
however, how did Madara get his hands on the Rinnegan? did he rob Nagato's corpse and plucked out his eyes, it wouldn't be impossible seeing how he can teleport anywhere in the world and he also has his assistant Zetsu, who can essentially travel through earth to track a corpse. I find it strange that Madara did not mention anything about Nagato, the sole Rinnegan user, in the same sentence. which is why I'm inclined to believe that Madara, in fact, has another Rinnegan at his disposal and it isn't Nagato's eye. so how could Madara obtain another Rinnegan, after all, we know that the legendary doujutsu only appears during times of strife or scientifically is seen as a genetic mutation. having more than one, kind of degrades the former explanation of its origins.
So then why did each body have the Rinnegan?
that brings us to the next point, how did Nagato produce more than one Rinnegan for his Pain Rikudou jutsu? I believe that answer to that is the key for figuring out how Madara could have gotten his hands on the Rinnegan. to begin, I would like to list a few points:
we know that the six bodies of Pain did not originally have the Rinnegan, but were at one time ordinary individuals. therefore, none of the bodies were born with the Rinnegan. however, Nagato channeled his chakra through the chakra receivers to each body and the state of his chakra determined the fighting abilities of each body as well.
- Nagato channeled chakra to each of the six paths of Pain through chakra receivers
- each of the bodies had a Rinnegan and could utilize one doujutsu
I realized that Nagato sending his chakra to a body, simply transmuted or changed a regular eye into the Rinnegan.
to explain, we must first go back to what Madara stated, the elder son of Rikudou Sennin, was born with his doujutsu and his "chakra". notice how doujutsu and chakra are inseparable. to solve the mystery of the Rinnegan, we must again use the Sharingan as reference since it was at one time the Rinnegan. as we have seen with the Kakashi Syndrome, Kakashi cannot utilize the full potential of the Sharingan as he does not have the chakra to do so while other Uchiha can. although it was mentioned that the reason was the Uchiha "blood", we know from recent evidence that the Uchiha inherited the doujutsu of Rikudou Sennin as well as his "chakra" which is passed down genetically as well. so in Kakashi, we have an example of a doujutsu not having its compatible source of chakra, what if it was the other way around? Nagato, bearing the Rinnegan as well as its compatible source of chakra, could simply channel his chakra into an eyeball and turn it into the Rinnegan.
the following arguments I'm about to make will validate my hypothesis. you may be wondering whether the act of simply transferring his chakra would permanently change an eyeball into the Rinnegan or not? what happens when Nagato does not channel his chakra to a body? as we have seen, Animal Realm still had the Rinnegan even after it had stopped receiving chakra from Nagato. therefore, we know that the change is permanent. furthermore, you might have a hard time believing that the act of simply transferring chakra could turn an eyeball into the Rinnegan? couldn't it had been simply apart of the Pain Rikudou jutsu and not a trait of the Rinnegan? let me bring you to another point that will further strengthen my argument and hopefully remove your doubts. remember, the Rinnegan was not only in each of the six bodies of Pain, but each of the summons of Animal Realm also had Rinnegan-like eyes. also, every summon of Animal Realm had chakra receivers to channel Nagato's chakra, thus changing their eyes into the Rinnegan. the same process was not limited to the six bodies of Pain, but to his summons as well, proving that it wasn't just apart of his jutsu and actually had something to do with his chakra.
How can Madara get the Rinnegan?
hopefully I have effectively etched my points in your heads, now we must come back to our question, how did Madara obtain the Rinnegan? Madara could have simply asked Nagato to channel his chakra into some eyes and transform them into the Rinnegan (POOF!) would Nagato do such a thing for Madara, would he really hand him such awesome powers? well why wouldn't he? we have to admit, Madara is strangely interesting and incredibly persuasive. we all saw how he transformed Sasuke into a ruthless killer with just a few words when he simply told him to dispose of Karin. aside from that, Nagato had already agreed to use a jutsu on Madara's behalf and he had already been in charge of sealing the Bijuu despite knowing of Madara. it is certainly possible that Nagato changed some eyeballs into the Rinnegan. likewise, Madara has recently revealed a whole laboratory of stored Sharingan, which is certainly a better candidate for changing into the Rinnegan. the Sharingan descends from the Rinnegan and contains some of its genetic traits and characteristics, thus being as compatible with the transformation just as a Mangekyou is compatible with another.
what if Nagato had not done this procedure for Madara? what if he died before he could have done this just as he did before using a jutsu for Madara? how would Madara obtain the Rinnegan aside from robbing Nagato's corpse? the answer is simple, Madara used Zetsu to change a Sharingan into the Rinnegan. remember, Zetsu can clone anyone he touches, replicating right down to their chakra. Zetsu could have easily touched Nagato and therefore can replicate a weaker clone of Nagato. however, despite being weaker and temporary, the purpose is served as Zetsu has Nagato's chakra in his databank. therefore, Madara can simply use Zetsu to change a Sharingan in his stock to a Rinnegan by replicating and channeling Nagato's chakra. it is interesting to note that Zetsu's body is being shown just as Madara restores his arm and brings the Rinnegan back into the story. if this does turn out to be the case, or at least something close, it's pretty ingenious if you ask me.
however, something has been troubling me. this is nice and all, however, Madara claims that his body is too weak and injured. What is the point of gaining the Rinnegan when Madara intends to restore his body first before doing anything else? Furthermore, if Madara has the Rinnegan or had it for a while, why didn’t he transplant it earlier? He has walked around with one eye for at least sixteen years, why not transplant the Rinnegan right now? Another important but crucial fact that comes to mind is that Madara intends to achieve a higher doujutsu, the “true Sharingan” by becoming the jinchuuriki of the Juubi. The “true Sharingan” seems like a mix between the Rinnegan and the Sharingan and is probably a doujutsu more superior to the Rinnegan. Something tells me that Madara does not intend to transplant the Rinnegan for himself. Does he have anyone else in mind, could Madara want to transplant the Rinnegan into someone else who holds great potential and who has the genetics to wield the Rinnegan? I’ll leave that for all of you to think about, discuss, and predict. Let me end this by bringing up another point. Why did Madara bring back the Rinnegan into the story right before Sasuke asked him to transplant Itachi’s Mangekyou? Why is the Rinnegan being brought back into the story just as Sasuke declares his desire to transplant his eyes?
