Magellan

Magellan is the warden in charge of Impel Down.

Appearance
Magellan is a large man that greatly resembles a devil. He has bat wings, and a gargoyle-like face. He has horn-like ornaments on his head which he can pull out and use as weapons. Underneath them, he has short black twintail-styled hair. He towers over a regular sized person greatly. He also has very sharp teeth and his hands closely resemble those of the Blue Gorillas. His uniform resembles that of a Nazi SS officer.

Personality
Magellan is a man with a rather distinct problem. Because of the powers of the Doku Doku no Mi, he delights in eating poisoned food. Though immune to the poison, he suffers from a severe case of diarrhea brought on from ingesting such poisonous meals. As a result, he spends approximately ten hours each day in the bathroom relieving himself. He tends to prefer "closed-off" spaces, possibly because of how much time he spends making bowel movements. He also seems to find it amusing whenever someone he doesn't particularly likes gets poisoned or suffocated by his powers, evident when he was seen chuckling at Hannyabal after he sighed a poisonous mist at the latter's direction. While he also does not tolerate Hannyabal's "poisonous" (the actual term used is punned with the word "distant") comments he himself is prone to use them against himself. He is also very ruthless, even with his own men, berating a guard who was poisoned by his Hydra.

Impel Down
He and Hannyabal are often at conflict with each other over Hannyabal's ambitiousness. Often Hannyabal will scold Magellan's behavior as he displays poor qualities as a warden overall, such as falling head over heels for Hancock and her charms. His actions will often invoke Magellan to send poisonous gas in Hannyabal's direction and out of all his subordinates he is the one most likely to be the target of Magellan's poison.

Magellan seems to care very little to none for the well beings of his subordinates, especially when it comes to serving his duties as the warden of the place. He shows his ruthlessness by using his poisonous breath to put his subordinates into place, and drench them in the corrosive Hydra when they are in his way of battle, without as much as an apology.

Criminals
As he has permission to kill any criminal within the walls of Impel Down, he cares little for them and will willingly use extreme measures against them. He does not tolerate their bad behaviors at all and when pushed to react just covers them in poison and leaves them with no cure. In turn, while most prisoners badmouth Magellan in his presence, they also fear him for his ruthlessness, and in particular, his Hydra technique.

Abilities and Powers
As the warden of Impel Down, Magellan has full control of the prison. However because of his constant diarrhea, he spends most of his time in the bathroom. Adding to fact that sleeps approximately eight hours per day and discounting meal times and breaks, he only works for approximately four hours per day doing his job.

Nonetheless, he has both the authority and power to execute any of the prisoners in Impel Down as he sees fit.

Devil Fruit
Magellan had eaten the Doku Doku no Mi, a Devil Fruit that allows him to generate and manipulate poison. Magellan can produce these poison in different strength and forms, such as breathing simple minor gas to put subordinates in place, blowing tear gas bubbles to stun the opponents, or create extremely fatal liquid poison. His most infamous technique that is well known to most prisoners within the walls of Impel Down is a three-headed dragon called the Hydra, which is composed of corrosive liquid poison that causes lethal nerve-paralysis and melts the victims at the same time.

Because of the fruit's powers, Magellan is also able to eat poisoned food without killing himself. However, while he is immune to the poison, the food instead causes him to have diarrhea.

Weapons
The ends of Magellan's horns are actually detachable, and can be worn like boxing gloves over four fingers (his thumbs stick out). The sharp points allow for the weapons to slash and pierce, and Magellan can also transmit his poison abilities through the horns and dissolve anything they touch.

Current Events
After relieving himself from a torturous time of diarrhea, Magellan met with Momonga and Boa Hancock.

There he received a report of an intruder running a muck with Buggy the Clown in Impel Down, but before he could be told who it was, Hancock used her looks to make him take her to see Ace immediately.

After arriving at level 5, Magellan became irritated with the screams of the prisoners, shouting out at Boa Hancock, so he used his special attack, the Hydra, and attacked one of the prisoners, stating he has the power and authority to execute all of them on the spot.

After Hancock left, Magellan received news about Luffy's infiltration, and Magellan ordered all forces to report to Level 4 to prepare for interception.

Magellan was later seen in Level 4 with all the forces to prepare for Luffy's arrival, all the while ordering his troops to pursue. The chief later jumped in front of Luffy and Mr. 2 Bon Kurei, intercepting them and preparing for combat.

He then goes on to fight with Luffy. During the fight Mr. 2 Bon Kurei tearfully runs away, Magellan recklessly uses his powers against Luffy and injures some of his own workers. During the battle, he explains to Luffy that he's aware of the latters intent to free Portgas D. Ace, and having broken into Impel Down despite its impenetrability is a personal insult to it's chief warden. Despite his advantage of having an armor of corrosive liquid poison, Magellan still received Luffy's Gomu Gomu no Jet Bazooka right in the stomach, even though it caused Luffy's skin to burn with poison. However he still managed to defeat Luffy by overwhelming him with enough poison to kill a normal man. He ordered Luffy to be taken down to the central tower of Level 5.

He then went to the passage between Level 4 and 3 and scolded the person whom he thought was Hannyabal (though in fact it was Mr. 2 Bon Kurei ) for suposedly leting Mr. 2 beat him and escape. He left the "captured" Buggy and Mr. 3 in his care and went away, ordering all men to concentrate on subduing the riot of prisoners at Level 2.

Trivia

 * He may be named after Ferdinand Magellan, a famous Portuguese maritime explorer.
 * Magellan's SS officer themed uniform and his devil fruit's ability to produce "poisonous gas" are possibly a reference to the methods Nazis used to execute their prisoners.
