Hans Hexen

Hans Hexen (ハﾝス・ヘクスエﾝ) is a Shichibukai and the captain of the Black Mass Pirates. Notable for being born in the Florian Triangle, he quickly gained prominence as a pirate and was recruited into his current organization by the World Government. He is one of the founders of ---, a supposed independent country for pirates and outlaws, along with fellow warlords Hornigold, Lich Stigma, and Belle Lionne. He acted as the most common magistrate, ruling over the land with his crew, and thus had his own unique designs for the "country".

He has eaten the Ekuto Ekuto no Mi, a Logia-class Devil Fruit that allows him to control and transform into ectoplasm.

Due to his actions, he is the main antagonist of Proud Line's third saga.
