I want to share with you the opinion that Hashirama is truly the only one who can beat the perfect Susanoo with powers which are yet unknown.
I think that it does not matter whether the perfect susanoo faces the kages, the Akatsuki or someone else.
Even if Akatsuki with the members of the beginning of the series will face the PS together with the Kage, they will have no chance.
The problem is, even if they are more, they can not do anything.
The normal susanoo is a few times bigger than a human:
and already this incomplete susanoo caused problems for the kage. now compare this susanoos with the tendrils of Mokuton:
they are as big as one tendril. and now look how big the PS is..
look closely at the tendrils, one susanoo is as huge as the tendril, humans are even smaller.
and now the power with one attack.
one slash crushed madaras meteor and then several mountains on top were cut..
does it really matter, how much of strong opponents will face this susanoo, if they can not do ANYTHING to it? 200 meters high, destroying mountains with one attack and is immortal, it can rebuild his chakra even if someone manages to make little damage.
one slash would have killed all 5 kage. one slash could kill all akatsukis, one slash could kill them all together.
i do not know what hashiramas ability was, but no one else can stop this.
