Gedatsu, nicknamed the Sky Boss, served as one of Enel's four priests in Skypiea, overseeing the Ordeal of Swamp. Imposing in build yet hopelessly absent-minded, he later tumbled to the Blue Sea below, where he abandoned his old life to run a hot-spring resort.
A dark-skinned Birkan of considerable height, Gedatsu sports a row of upward-jutting tufts that ring his head from ear to ear, plus the wings typical of his people. His usual outfit pairs a purple jacket and trousers with black gloves and shoes, a pink shirt, and a scarf-like blue tie, all cinched by a broad white sash bearing a red circle that echoes Japan's flag. Hidden in his footwear are Milky Dials that grant him flight. Eight years prior his look was nearly identical, save for a plainer tie and an unstriped shirt.
Gedatsu ranks among the strangest figures in the series, plagued by a string of bizarre habits he never notices himself. He will roll his eyes back until he is blind, forget to breathe or blink, dig while standing on a wall, stuff food into his ears, or aim attacks at his own allies, requiring constant correction before he frowns and cries out that he was careless. This goofiness clashes wildly with his fearsome appearance and earned him a reputation for incompetence, which left his Ordeal with the highest survival odds of the four. Even so, in battle he is serious, ruthless, and aggressive, untroubled by the deaths of his own men and viewing rescue by an enemy as a disgrace.
In combat Gedatsu commanded the Ordeal of Swamp, a trial with a fifty percent survival rate, blanketing the field with swamp clouds dense enough to trap and suffocate anyone who sinks in, since struggling only drags a victim deeper. Concealed Dials power his Numagumo Burger, a swamp-cloud blob meant to smother a foe's head, and his sleeve-tearing Jet Punch, a strike so fast he seems to vanish, while Observation Haki, called Mantra in the Sky Islands, lets him read an enemy's intent a moment early. The Milky Dials in his shoes and the others across his body kept working even after he fell to the surface. Born on the sky island of Birka, Gedatsu was among those Enel gathered after destroying it, following him to Skypiea where Enel seized Upper Yard and declared himself God. During the Skypiea conflict he and his fellow priests pursued an intruder before Enel obliterated the man with lightning. Later, in the survival game, Gedatsu confronted Chopper but fumbled his every move, unable to see with his eyes rolled back and too quiet to introduce himself. He demonstrated his swamp clouds, but Chopper spotted his weakness in the Dials on his feet; after one was knocked loose, Gedatsu lost control in the air, was driven into his own trap, and accidentally flew downward to the Blue Sea. Crashing onto a hole-pocked land called Ukkari Hot-Spring Island, he was taken in by an old man named Goro and helped build a hot-spring resort, defeating the Dirt Boss and Forest Boss along the way and ending up as the resort's clerk. By this lucky exile he became the only one of Enel's priests spared the punishment of Cloud Drifting.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
Gedatsu lost control while fighting Chopper in Skypiea after one of the Milky Dials in his shoes was knocked loose, sending him plummeting to the Blue Sea below. He was taken in on Ukkari Hot-Spring Island and eventually became the head clerk of its hot-spring resort.
Gedatsu's fearsome height and his command of the Ordeal of Swamp belie a reputation for incompetence caused by his bizarre absent-minded habits. He is serious and ruthless in combat, but Chopper spotted the weakness in his Dials and turned Gedatsu's own swamp cloud trap against him.
No, Gedatsu is not part of the Arabasta storyline. He appears in the Skypiea arc as one of Enel's four priests, overseeing the Ordeal of Swamp in Upper Yard.
Yes, Chopper defeats Gedatsu during the Skypiea survival game. After noticing the Dials hidden in Gedatsu's shoes, Chopper knocked one loose, causing Gedatsu to lose control in the air and fly into his own swamp trap before crashing down to the Blue Sea.
Gedatsu relies on Dials rather than a Devil Fruit. Concealed Dials power his swamp-cloud Numagumo Burger and his sleeve-tearing Jet Punch, while Milky Dials hidden in his shoes grant him flight.
