Did Black Zetsu beat Madara in a fight? No. We are talking about a head on fight here. Please use examples that correlate to the situation.Ohh so black zetsu >>>>>hashirama????yeah ok bro.Lol
In the end he needed kurama to match, it doesn't matter if you think he didn't
Naruto only did as well as he did because Pain was in a weakened state.Madara would win imo. Sage Naruto defeated 6pop with Kurama, and EMS Madara had Kurama as well. EMS Madara > SM Naruto. And yes I realize that just because Madara was stronger than Naruto at that time doesn't mean that he would necessarily have an easier time against 6pop, but I think that he would.
