could you imagine taking out all the current warlords and somehow having the rest of the "worst generation of pirates" bend a knee to luffy as if he becomes the new whitebeard with sub branches of his pirate fleet? Would be GG
The only Warlord that would give Luffy trouble would be Mihawk. He is presumed to be on a similar level of power to Shanks. And he did train Zoro as well.
I think you were referring to the Yonko though. Because they're the the four emperors of the sea. But if you take down a Yonko you pretty much fill their spot.
I think in due time we can see that sort of thing happening to Luffy though.
