Only Mrs. Uzumaki-Senju and Naruto "tamed" Kurama.
Madara "controlled " him with his SG. They way I see the fight it was similar to Minato vs Obito.
Hashi takes Kurama out of the fight by subduing it with wood dragon(lol), Mito then sees it as an opportunity to take it off the playing field for ANY future attacks. If you remember it was Hashirama that passed the Bijuu to the other villages initially. THAT IS POWER, by the way.
Mito Uzumaki-Senju, was more than likely present when Madara attacked, maybe thinking Hashirama would be focused on protecting her. I mean they were out away from the village, probably just spending quality time together. The fight created Valley of the End, so before that it was just an area of forest.
I'm with Amuro on this....
Madara wanted to kill Hashirama, just couldn't for whatever reason.
I think that the story he told Obito is a little embellished though. he lost and has too much pride to say, "yeah I have EMS and the 9 tails but I got severely injured. I noticed I had some of his flesh in my weapons form an attack. SO I experimented and it healed me but I was still very weak, I couldn't face him again."
"So as time passed I unlocked the RG in my old age, I read the Uchiha tablet completely and found I could prolong my life by summoning the Gedo Mazo. After that I came up with the Infinite-by product of the Sage of Six Paths technique-Genjutsu."
"So I meet this emotionally fragile kid and manipulated him into thinking we had the same goals. Get this, wait for it....he even agreed to bring me back from the dead,lol"
just saying if he could have killed Hashi he would have a long time ago. Considering how the Senju push kindness and forgiveness, Hashirama probably only fought to kill Madara at VotE.(pure speculation, I admit)
