tobi is the elder son of the sage,my reasons for thinking so is...
1.tobi was able to use izanagi when fighting against konan.and we all know that in order to use the power of izanagi,the user must have the dna of both the senju and uchiha clans.the elder son is one of the only few with both dna
2.it was stated in the manga that the elder son have the sage's eyes,which was the rinnegan.and when fighting konan,tobi said that he was the one who "gave" the rinnegan to nagato.
3.tobi's unlimited moon tsokoymi plan is very similar to the phrase and beliefs of the elder son. the elder son believed that "might was the key to peace."
4.i think tobi's dimension defies the rules of time.i say this because tobi held foo and torune hostage for so long without food and water and when tobi brung them back to get sacrificed by kabuto they was still alive.and i was thinking thats how the elder son stayed alive for so long and out lived his younger brother.if you guys dont know who foo and torune is, they was danzo's bodyguards.
5.when the manga showed the pic of the elder son and younger son about to fight.the younger son had the sage's staff ofcourse because he was the sage's successor and the elder son was weilding a sword.this puzzled me because when itachi told sasuke the story about the "masked man" seeing him before the uchiha clan massacre.they showed tobi weilding a sword on his waist and having long hair.
6.tobi isnt just an uchiha but he is a uchiha that no one knows about.and its not because of his mask that no one knows who he is,its because he never existed in history. and when i say this i mean that nobody heard of the elder son and the younger son before until tobi told sasuke and the 5 kages himself. not even jiraiya knew because when jiraiya told the story about the sage to us,he never mentioned anything about the sage's sons and its probably because he never knew about it.no one knew about the sons.how come tobi knew so much imformation about it than everyone else? and as jiraiya said to us before fighting pain, he said it was myth but when tobi told the story to kakashi and naruto at the kage summit,he never said anything about the sage and the sons being a myth he said it was based on real events(check chapter 462).and this is why tobi used madara's identity...because if he was to use his real identity then no one would had tooken him as serious as when he called himself madara.it makes sense to me.he couldnt just go around saying "im the elder son of the sage" when everyone believed that the sage was nothing but a myth. he's just gonna look like a crazy idiot to everyone.
tell me what you guys think about my theory.feel free to to disagree,just dont reply with that "tobi is obito" bs.tobi is not obito.i dont have to explain myself to why tobi isn't obito.if your a true naruto fan and have common sense, you would know obito can never be tobi.
Good points. However:
1. Tobi's wood style dna seems to com from his white squishy regenerating body parts, and I assume they come from zetsu, but they are definitely external from his body. If that is the root of his senju dna, he is guaranteed not to be the elder path. Also, Izanagi does not require senju blood, but having senju blood reduces the physical strain and reduces the wait time to reuse the eye, because without it there is a ten year waiting period.
2. They were not literally given, they were passed down. It was not the same eyes, but it was the dojutsu ability that was passed down. Look at a picture of him. Use google, the wiki, or whatever. His eyes have a different dojutsu then rinnegan. It is similar and definetly a relative, but the key difference is the spiral is different and the coloration is a much lighter purple. The fact that we haven't seen said dojutsu is proof enough it is not him. And besides it is much more likely that the rinnegan came from the actual Madara's body, and because Edo Tensei revives its subjects at their peak, he came back with this ability.
3. Eye of the Moon is not might. It is genjutsu, the most passive thing that can be done in the entire naruto universe, aside from the genjutsu from the paths. And Tobi does nothing with might. All he does is enter another dimension and hides. I'm sure that he has some jutsu, and if he was the elder son I'm sure that he would love to show his might even if it's unnecessary.
4. You stopped speaking english here, but your probably right. However it is or is related closely to Kamui. I think that even though he is probably Obito, even if he is not, Obito could unlock a level of Kamui that could achieve this ability. If Obito could do something similar to this, it is not very impressive that the elder son could do this nor is it likely it would be the extent of his power.
5. Valid.
6. This last part is interesting. I am not gonna say that you are wrong on this part, and what I'm gonna say is less likely, or just as likely but a less practical approach. I believe that this information came from Madara Uchiha. If he had rinnegan for long enough before he died, this is info he could have obtained from the Uchiha hideout on the tablet using his rinnegan. I have no other explanation for that. Your logic makes so much sense, and mine does but it is much more convenient.
Overall, your logical, but your first points helped me prove it wrong. At least in my eyes. I do think that it will be Obito and I've thought that and known that for a long time. I don't like it, and I'm banking on the ever shrinking possibility that it is Kagami, but as of now I'm pretty sure that he is Obito. It annoys the shit out of me, but if kishi does a small amount of explanation he could easily make sense of it. Don't call me an idiot, kishi is doing it. But whatevs. If i knew how to + rep, I would.
