I can only say one thing, taken out of the god of death himself edo tensei madara that the only man he feared is Hashirama..
Nagato has an immense arsenal of chakra and abilities, the eyes of the sage himself. But a wise man said once a pebble can defeat a sword in the hands of the right user.
-Tsunade said she couldnt believe how her grandfather fought someone like madara on his own in the fight with edo madara. because madaras power is so off the charts. yet she saw how nagato destroyed konoha village in one single shinra tensei. and then left naruto to take care of things
Hashirama level of jutsu and power is of legend and he is the will of fire himself. Wood Element spurs that kill and paralyze you, healing abilities which madara praises. and uses jubies as his weapons..
