Naruto probably would of still got pinned down but Hashirama would proabaly force Pain to do a chibaku tensei earlier because Hashirama is a complete monster
Hashirama aslo would of smashed asura path into pieces and not just stand there but more people would of died because Tsuande wouldnt be healing everyone
What if at Pains invasion hashirama would be the hokage of the leaf instead of tsunade? what do you think?
