One Piece revealed what happened when Oden Kozuki tried to retake Wano in the newest episode of the series! One Piece's Wano Country arc has been spending the first half of its third act exploring Oden Kozuki's past and his adventures in Wano and through the rest of the seas as part of both Whitebeard and Gol D. Roger's crews. While these oceanic adventures were important in revealing some of the major aspects of the series' lore, the newest episode was probably the most important for Wano yet as Oden finally returned home.
