Well not sure about that. It was stated somewhere a Jin brings out the full potential of the Bijuu. Madara was controlling a mad destructive Beast while fighting Hashi With Mito there Hashi would, not only have to fight off Madara, but a bijuu enhanced Uzumaki with OP seals and all. Not sure if he would win that.You mean mito and madara vs hashi, madara would still lose, if the kyuubi couldn't help mito won't do anything
