Well Luffy and Law will challenge a Yonko but we don't know, Shanks is way more powerfull also Blackbeard, but it could be Big Mom and why Kaido?

Why Luffy will go challenge someone we doesn't even know? Kaido?

Drake said that he wants to defeat Kaido.

Other supernovas i do not know. Law is Shichibukai and it's hard to know what Oda will do in the future that man is a genius!
