Crocodile / Mr. 0

Crocodile is the leader of Baroque Works, a secret organization of assassins and spies, and a member of the Shichibukai. Utilizing Baroque Works, he incites rebellion in the kingdom of Alabasta in order to gain access to the Poneglyph hidden beneath the palace. He believes it will reveal the location of the weapon Pluton, which Crocodile wishes to gain control of in order to establish his military power. He is defeated by Monkey D. Luffy and stripped of his Shichibukai status by the World Government, after which he is imprisoned. Crocodile ate the fictional Devil Fruit Suna Suna no Mi (Sand Sand Fruit, スナスナの実), giving him the ability to control sand, as well as avoid damage by turning into sand. According to series creator Eiichiro Oda, Crocodile's bounty would have been more than twice it's value if he wasn't a Shichibukai (his former bounty before accepting Shichibukai status was 81,000,000).
