i highly doubt that, but how amazing was that chapter! what im shocked at, is that the 1st hokage basically invented the jinchuriki, since he is the only true jinchuriki that can fully control multiple beasts, when he started sharing them and other countries started implanting them on people, but no1 could control them because non had the 1sts powers!!
Madara is the mizukage, makes sense since whatever country hired the senju the opponents hired uchiha, so if hashirama was in charge of the leaf, madara would simply goto another country and start over. And i think we can excpect a great war pretty soonish, maybe the naruto series will end with a massive flurry off battle before eternal peace lol!! great chapter tho
