One Piece World : Yonkou Kaido
Kaidou (カイドウ, Kaidou) is one of the Yonkou.
At one point in his life, he fought on equal footing with Gecko Moria and defeated him in the New World. Though it has yet to be fully explained how Kaidou defeated Moria, it is implied that he’s responsible for the destruction of Moria’s original crew
When Ace was announced to be executed by the World Government and Whitebeard was making a move to rescue him, Kaidou attempted to attack him. Shanks however intercepted Kaidou before he could reach Whitebeard.
As of now, it is unknown which of the remaining two unrevealed Yonkou is Kaidou.
