Enter Oden Kozuki
One Piece has spent the entire Wano Arc building Oden Kozuki into this lather-than-life legend. How he was the only person to injure Kaido. How he was a member of the Roger and Whitebeard Pirates. Yet the Wano Arc’s entering its climax, and we know so little about the man. Thus, before the final battle for Wano, One Piece gives us its traditional, expository flashback. This is the story of Oden Kozuki.
