So who do you guys think is the current strongest pirate? And please don't say whitebeard, why? Because he's not the strongest pirate, sure he's been dubbed the "strongest person" in the world and during Gol D. Roger's time, he was maybe the 2nd strongest, but that was during his "era" and that has since long past. Now he's just a strong man connected to a bunch of nurses and medicine. Heck i"m not even sure he can last in a fight against Shanks, he may be able to hold his own for awhile but pretty soon, he'll lose because of his age and sickness.
So think, during this era who's the strongest? In my opinion its either Blackbeard or Mihawk. Blackbeard, because it seemed that he took down Ace without any difficulty, and he was able to injury Shanks without his logia powers, plus i don't think we've even seen his full power yet. Mihawk, well because he's the strongest swordsmen AND he can cut down giant ships with one swing. And that to him was like swatting a fly.
