I would agree that Luffy could not beat Kaido if they both went full out. Although I think that if they were to collide and actually fight, Kaido would at first underestimate Luffy.

Maybe not to anybody else, but to me I think it is quite obvious that Kaido has a Zoan devil fruit. It makes sense that a beast leads the beasts. Wether it is a Mythical, Ancient or a normal Zoan I don't know. (Although my guess would be something like king kong or some shit xD)

So I think that Kaido would at first fight luffy without using his devil fruit ability and then underestimate him. Kaido see's that Luffy is at a more advantageous position and decides he must go into his devil fruit transformation to win the fight.

Maybe with this prediction I am underestimating Kaido. Like you said, he is a Yonko. But hey. I love Luffy and just look at how strong he was pre timeskip! I think pre timeskip, from all the shichibukai, only blackbeard, Mihawk, Kuma and Doflamingo were stronger, making Luffy stronger than half of them; Crocodile, Moria, Hancock and jinbei (Jinbei is debatable). We are forgetting that he got to this position/strength, being completely self tought! And now after timeskip, Rayleigh trained him and he was fighting on par with Kizaru! But then the question is... Would Luffy beat Rayleigh? But that is for another blog! (I think he wouldn't be able to. Not just yet anyway).

Meh, just my thoughts. Luffy would whipe the floor with any supernova though. Sure they would get some hits on Luffy, but only because he would not understand their DF power at first. Law has an OP power, but I think Law would still have trouble keeping up with his speed.

Big Mom however.. What happened to her? I want that fight to happen first. In that fight, I think it would be an intense one with Luffy coming out on top barely.
