Here's a thought about what could happen

[Senju Smash Bros]

Say hashirama and madara do fight what if half way through the fight something unexpected happens and hashirama and the other hokage are either un summoned or are immobilized do you guys think that maybe either the rookie 9 will fight madara or team 7 aka naruto sasuke and sakura fight him and if say team 7 fight madara and somehow defeat him imagine how awesome that would be then that means everyone everyone even people from the leaf will both fear and respect team 7 cause they defeated the most powerful shinobi ever and lived to tell the tale.

P.S even sakura will be feared and you never know if tsunade is alive she may even fear sakura.

I just want them to be seal , the past can not win them the battle

I doubt madara will start fighting his man lover hashi and then allow or accept him to be sealed or immobilized mid fight. Madara would go crazy and try to either kill Oro or try to undo the edo tensei.

I doubt it.

This is the way I see it: EMS Madara needed Kyuubi to even contest Hashirama, proving how far above Hashirama is in the manga in comparison to others. Even with Kyuubi he got taken down Mid-Difficulty. Now take away Kyuubi and Hashirama beats him at most, mid-difficulty. But now add on Rinnegan (Say equal to Rinnegan) AND Mokuton and this puts Madara a tad bit ahead of Hashirama, and if he were to win, it would be extreme-difficulty. This means, adding in anything else (People) will be enough to take Madara down (Presumably Tobirama). Obito is the final villain in my eyes. Madara may have orchestrated it all but Obito carried it out to absolute perfection and actually has motives in comparison to Madara's "Losers-Winners" thing. So Madara will be sealed along with Hashirama/Tobirama (Both) but not without witnessing Naruto become the next S06P (Rinnegan+Full-Kurama). It will be Obito vs Naruto. By that time Sasuke will have gotten redemption for his clan and that leaves Naruto to finish off who is the root of all his pain in his life; Obito, who indirectly killed his parents and placed the burden of being a Jinchuriki on him.

Battle will be: Naruto (Rinnegan+Full Kurama) vs Obito (Rinnegan+Mokuton+Sharingan-Kamui)
The battle of the true parallel in the story. Obviously through plot purposes Naruto will win, and that will leave the Juubi to be dealt with. The Sage will probably appear in Naruto's psyche through his chakra essence and explain everything, and the keys behind using Yin-Yang Release (Aka Creation of All Things) to re-split the Juubi and it will commence from there.

At least I think/hope that will happen.
