Zast Ushinatta (ザスト失った Zasuto Ushinatta?) is currently being held in Impel Down, as the only prisoner without being submitted to regular tortue. Since he had first come willingly, and then shown his uncanny ability to escape almost anything, and agreed to not cause havoc for a couch, no torture, and good food, making him more of a guest than a prisoner. He acts as an informant for those seeking him, ranging from visitors to the prison to marine officials. There are rumors that a marine is working with him and helping him make orders to members of Denizen Meats, but this is unconfirmed.
