Magellan is the vice warden of Impel Down. He was formerly the chief warden, but after his failure to stop the jail's one and only mass-breakout, he was replaced by Hannyabal and demoted to vice warden. He was the main antagonist during the Impel Down Arc.
He's usually not one to be included in top 10 strongest characters list, but in my opinion he's probably one of the strongest in one piece.
-He looks like a scary devil
(Magellan, despite being occupied by intense diarrhea for 10 hours per day and sleeping for another 8, is still capable of easily co-ordinating the defense squads of Impel Down in case of a potential break-in or break-out, as well as being fully aware of all the mechanics of the prison's traps.)
-Super Human Strength
(Even without his Devil Fruit powers Magellan is far stronger than normal humans, as he easily blocked a wax-covered Gomu Gomu no Stamp with one arm, as well as pillars of stone hurled at him by Inazuma with both of his forearms. He pinned down Ace with just one arm.)
(He is also incredibly resilient, as he took many of Monkey D. Luffy's Gear Second attacks straight on (an impressive feat as Luffy's Gear Second attacks are capable of breaking through the strongest defenses quite easily) and managed to stand back up to continue fighting with no lasting injuries, as well as receiving multiple shots of cannon fire without any resulting injuries.)
-Devil Fruit( Doku Doku no Mi)
(One of the nastiest powers in One Piece.Even if manage to beat him you'll probably still die of poisoning.)
-Hydra(Obliterated Blackbeard's crew in one move, probably the fastest battle in whole One Peace)
According to Oda it happened because they underestimated his power, but to me it still one of the most impressive feats.
-Venom Demon: Hell's Judgment
(Was used and dissolved the wax armor Luffy was wearing. Venom Demon: Hell's Judgment appears as a gigantic, skeletal-looking demonic beast, and Magellan has stated that the poison used is powerful enough to "destroy Impel Down itself". Not only is the poison more lethal and caustic than Hydra, but it also spreads out from any surface it touches, literally "infecting" everything, including stone. It is unknown whether there is any antidote for this poison, but seeing that it instantly kills the afflicted once the infection completely covers the victim, no such antidote may exist.)
-Has diarrhea because he likes eating poisoned food(Which is not really a problem if he stops eating poison)
-Standard devil fruit weakness
So what are your thoughts about this scary guy?
How strong is he in your opinion?
