6- DRACULE MIHAWK
Dracule Mihawk is a member of the Shichibukai and the “Greatest Swordsman in the World.
We all understood his awesomeness, when in one of the first episodes he slashed and beat Zoro so easily, using just a little knife. He also trained him years later, in the two year gap of the time skip. That’s what we do know regarding him, but is there more to it? What is his role really? We haven’t seen enough, and that’s for sure. He certainly is a mysterious character.
5- KAIDO
As one of the Yonko, Kaido is among the strongest pirates alive, renowned as the “Strongest Creature in the World”.
He appears to have eaten a Mythical Zoan-type Devil Fruit that allows him to turn into a serpentine dragon.
Kaido doesn’t seem to have a true intent of becoming Pirate King, his endgame goal seems to be nothing more than one big war that fuels his lust for destruction and strength that will ultimately be his final act.
4- BLACKBEARD
Marshall D. Teach, also known as Blackbeard, is the admiral of the Blackbeard Pirates and one of the Yonko.
Blackbeard has become the first and, so far, only user to wield the powers of two Devil Fruits at the same time. This has made many fans go crazy and spout wild theories on how he managed to do achieve this.
