Magellan

Magellan was one of the Chief Wardens of Impel Down before Blackout's arrival. His current status following the liberation of the prison is unknown.

Appearance
Magellan has been described as resembling both a gargoyle, due to his sharp, angular features, and a mandrill, due to the blue markings beneath his eyes and thick black sideburns. He is a gigantic man, three times the size of an average human. He wears a black-colored suit with a red shirt underneath. The horns that protrude from the back of his head are not real horns; they are detachable weapons that conceal his twintail-styled hair.

Personality
Magellan was completely loyal to the Galactic Government, and took his role of Chief Warden very seriously. Although he is not as violent as Shiryuu, he was not averse to executing prisoners when he believed they had behaved badly enough to warrant capital punishment. When Magellan discovered that Shiryuu had been killing prisoners just because they were prisoners, he found his behavior abhorrent and immediately engaged him in battle.

Magellan has several eccentricities, the most notable of which is his preference for poisoned foods. Because of the Poison Devil Fruit he eats, he can consume large amounts of poisoned foods without worsening his health; however, the side effect of this is frequent bowel movements. As a result, he spent most of his time in the toilet and not on patrol; it was because of this that Shiryuu's behavior remained unnoticed for a long time.

History
Long ago in Impel Down, there was no Vice Warden. Instead, there were two Chief Wardens: Magellan, and the much more dangerous Shiryuu. Both were equals in power, but Magellan's working hours were limited by the gastrointestinal aftermaths of his eating of poisonous foods, so Shiryuu was considered much more dangerous.

One day, while Magellan had been blessed by a rare reprieve from his stomachaches and likewise, he was on patrol in Level Two, where he discovered a grisly sight: Several dismembered, disembowelled or just beheaded prisoners strewn about, laying in pools of blood and guts. As he got deeper, he discovered Shiryuu, blade soaked in the blood of the prisoners. Shiryuu had always been sadistic and believed the prisoners to be no more than trash, but this was simply crossing the line. Magellan narrowly defeated Shiryuu in battle, and sentenced him to death in Impel Down, but he gave Shiryuu a postponed sentence so that he could rot indefinitely until the Galactic Government decided that the execution of a vicious criminal would boost their popularity.

After the incident, Magellan stayed on as Chief Warden, alongside new staff members Vice Warden Hannyabal and Chief Guard Sadi-chan.

Several years later, just before Blackout attacked the prison, somebody gave Magellan a warning and instructions on how to escape. If one were to thoroughly examine Level Six, they would find that no significant residues of living creatures are left for all of those prisoners thought to have been killed -- Essentially, that kind of blast in such close proximity would have fossilized them. His current status is unknown.

Abilities & Powers
The Poison Devil Fruit that Magellan ate enabled him to create, control and consume large amounts of poison without damaging his health. Magellan often used this power to exhale poison gas or to secrete liquid poison from his body. The poison Magellan created was slightly acidic and could be used to burn through surfaces.
