Hashirama's Death is unkown. But I doubt it is the same as Second's, it is most likely due to sickness.
Again you don't get it do you:
Madara says: Edo Madara = Hashirama
So if your saying that Madara is not far below hashirama back in the time.. then your saying Madara didn't get that much upgraded.. But yet he did.
Rinnegan and Mokuton and Edo tensei MADE madara on Hashirama's level. (According to Madara).
And the Video is canon. And Mito is the one who sealed the Kyuubi within herself. Hashirama feared Kyuubi's power?? well considering he took control of him easily I doubt it.
The video was tobi's interpretation of the past that he was telling sasuke. He telling sasuke a sob story, including telling him that the kyuubi attack was a freak accident. I'm honestly tired of repeating myself cause i've said that about four times already.
Are you kishi? no? then you have no real proof of how much difference there were between them. You're just assuming because you like the character and trying to find the most miniscule details to back it up.
Well all the things madara said could be misinterpreted. He never actually said that he lost to hashi or admitted to losing if i'm not mistaken. He never said that hashi's power is greater than his current state, only that he had the potential to stop him. That potential could just be a seal only hashi knew to supress some of madara's power or take away the senju dna similar to what orochimaru did with kabuto.
So there is no true answer until we see it for real in the manga told by a reliable source. Again the video from generations was Tobi's story of the past. We didn't see susanoo in that video either if you really want stick with it, so it can be assumed that he didn't even awaken it due to what I said in the previous comments that you should read because it covers all the flaws of what you said.
End of the line is you made a pointless thread about a fight that we know hardly about and act like what you said is the truth because you love Hashi and in process bash Madara's power. Is there a reason for the thread other than what I just said?
