Doku Doku no Mi

The Doku Doku no Mi, or Doku Doku Fruit, is a Paramecia Devil Fruit eaten by Magellan, the Warden/Chief of the World Government prison Impel Down. Since "Doku" means "poison", Magellan has become a 'Poisonman'. Thanks to that, he can eat poisonous food without killing himself. He also can breath poisonous gas without effect and he can release a lot of poisonous gas.
