Madara obviously takes this against Pre jin Hagoromo.
It took at least Post Jin Hagoromo's power split in two parts given to Naruto and Sasuke to stalemate Madara and yet we have never seen him go all out.
hagoromo has a far more powerful will so his cuts right through madara and all his susanoo. his halves were pressuring him and now hagoromo is here instead and your saying he loses. i cant imagine prime madara looking at hagoromo and not shitting his pants
