**EDIT: I meant chapter 574**
* In the latest chapter Suigetsu found what seems to be a scroll left behind by Orochimaru. According to Suigetsu, this scroll has the ability to change the war and it is also very favorable for Sasuke. Lets leave it at that for now…
* Now, according to Tobi, a man who has lied multiple times about his identity, claimed to be “No One” in a fight which will decide the outcome of the war. It has come to a point where his identity is meaningless now.
* When the real Madara was resurrected and learned that it was Edo Tensei, he immediately thought of a certain person capable of controlling it. That is when Kabuto broke in and said that he is “His assistant”.
* How do we know that he did not have Tobi in mind? We know this because Kabuto had to give Tobi a crash course in Edo Tensei and explain every detail of it. It’s an extremely secret Jutsu that only two Shinobi are known for by Madara; The Second Hokage and Orochimaru.
* How does this all tie in with the scroll left behind by Orochimaru? Orochimaru is a ninja capable of bringing the dead’s souls back to life and even transferring souls. He is also great with DNA science. For example, he successfully implanted Senju DNA and Sharingans into Danzou’s arm and he created Yamato.
* We know that Tobi is a conscious being who possess both Uchiha and Senju DNA. We also know that he is old and his limbs can be easily replaced by a White Zetsu-like material when they are destroyed. We know that White Zetsu is made from the cells of the First Hokage. We know that Senju cells extend ones life.
* Back to Madara. He has both the EMS and the Rinnegan. The Rinnegan is achieved after the EMS is gained. This means that only one of two siblings are able to achieve the Rinnegan in a life time and gain a portion of the Six Path’s power.. The only set back is that the Uchiha only have one part of the DNA needed to fully control the Rinnegan. That also means that they don’t have access to all the Jutsu’s within it. That is why Madara fought The First, simply to steal his DNA. At this point in time Izuna has already kicked the bucket after loosing his eyes.
* After his fight with Hashirama, Madara awakened the Rinnegan but he lost the Kyuubi, which he learned to control from the Uchiha tablet, and he lost a great portion of his strength. He gained the cells of the First but he no longer possessed the chakra required to suppress Hashirama’s chakra and control the Rinnegan.
* He read the Uchiha tablet and learned of the Juubi in the Moon. He wished to become the next 10 tails Jinchuriki and activate the Moon’s Eye but he could no longer achieve the full power of the Rinnegan. He had to search for some body with chakra capable of controlling the Rinnegan.
* The Uzumaki clan is a clan we don’t know much about. It’s true history hasn’t been revealed yet. What we do know is that they posses an extremely large chakra, they are the best at sealing Jutsu and that they are best suited to be Jinchuriki. My guess would be that the Sage of Six Paths hailed from the Uzumaki clan.. That may explain why they were hated for their powers.. Anyway, that is precisely why Madara found Nagato before going blind and dying. To implant his Rinnegan into him so Madara could be revived, full of life and chakra able to control the Rinnegan and Senju cells at once.
* Madara realized that he needed somebody to carry out this plan for him. Somebody he could trust no matter what.. His dead brother. But how? All he had was Izuna’s corpse, his own Uchiha DNA and Hashirama’s DNA.
* Now let’s jump back a series. How did Orochimaru get his hands on the DNA of the first two Hokages? Grave-robbing? I doubt Konoha would ever let the secrets of their bodies be revealed and accessed so easily. My guess it that he inherited it from Madara.
* Madara went to Orochimaru seeking assistance in bringing Izuna back to life and a certain experiment to extend his life. An experiment to ensure that whatever may happen, Izuna will be around to activate Nagato’s Rinnegan and influence his life decisions to the point where he revives Madara again. Izuna had to be immortal.
* What was the experiment? To create Zetsu, a life form consisting of half of Madara’s DNA and Half of Hashirama’s DNA. That is why Zetsu has two different personalities. One is a reflection of Madara’s personality and the other is Hashirama. Black Zetsu is serious like Sasuke and White Zetsu is silly like Naruto. The primary purpose of Zetsu is to supply life and chakra.
* Back to Edo Tensei.. Kabuto said that a living sacrifice is needed for it and then he demonstrated how it’s done by using Fu and Torune as examples. Kabuto also revealed that he is able to make changes to the body and alter it’s DNA.
* After Madara and Orochimaru created Zetsu, they used the Zetsu material to alter Izuna’s body and make him immortal. He’d be able to replace any of his body parts as long as he could replace them with some new Zetsu. They then sacrificed a body to complete the jutsu.
* Before that, Madara told Orochimaru, a younger ninja at the time, that he would also be included with the plan he had in store but he did not reveal the secrets of the Uchiha Tablet to him. Orochimaru willingly went along with the plan because he was in the presence of Madara. So Orochimaru completed the scroll required for the special Jutsu to bring Izuna back. They then sacrificed a body for the ritual and Orochimaru successfully brought Izuna back.
* Madara and Izuna then ditch Orochimaru, leaving him feeling extremely curious and used. That’s when he started forming his theories. He wanted to know what they were up to so he started his infamous research.
* Madara tells Izuna all the secrets of the Uchiha tablet, the Rinnegan and Nagato. He gives him all the intel on Konoha. They hatch one final plan before Madara dies. A plan to take over the world.
* What was the plan? For both brothers to have the Rinnegan and one day rule the world together, the Moon’s Eye Plan. Izuna’s duty was to collect the Jinchuriki in the mean time. One setback.. Izuna died without his eyes. He desperately needed eyes and lots of them. He needed eye’s capable controlling the Kyuubi. So instead of taking the risk of exposing his existence by killing off Uchiha clansmen, one by one for their eyes, he only killed one at first.
* He then made sure that Nagato would awaken his Rinnegan and share a deep-seeded hatred for Konoha by placing two Konoha Shinobi under his genjutsu to kill his parents in front of him. That is why the two shinobi who killed his parents immediately questioned their reactions once the deed was done. About a decade later, the original Akatsuki is formed.
* Then, Izuna stole the Kyuubi and added a massive amount of tension to the already shaky Uchiha situation in Konoha. This would later lead to the relativity easy massacre of the clan. Izuna asked Shishui to aide him at first with his eyes but Shishui could not bring himself to betray Konoha. He trusted his eyes to Danzou and Itachi so Izuna could not get his hands on them. Izuna learned of this and went to Danzou under his new alias, Madara. He then framed the Uchiha for the Kyuubi attack and blamed Itachi’s dad for conspiring a coup de etat. With this fear in mind, Danzou talked Itachi into killing off his clan for the sake of Konoha.
* Izuna is Tobi. He wears a mask to protect the fact that Izuna is back. His brothers name is much more useful than his own. Kabuto was aware of Tobi’s lies because Orochimaru already had Madara’s DNA. The scroll Suigetsu found might be capable of ending the jutsu which allows Tobi to live. Thanks for reading, I may have left some things out.
