One Piece has brought in a new member of the Akazaya Nine to the anime with the previous episode of the series, and the newest episode showed off what this new member could really do with a stunning display of Kawamatsu's strength. After being teased when Luffy first arrived in the Udon prison, Kawamatsu the Kappa was revealed to be the full name of the prisoner locked away within a showy cell while being fed poisonous fish. But with Luffy causing chaos, Kawamatsu found it as the time to move.
