Sebastian is a Wotan of the false kelpfish fish species, and a member of the World Pirates.[2]


Sebastian Without His Sunglasses

Sebastian's eyes.

As a Wotan, Sebastian is very large and muscular, about the size of a small giant but with the physical traits of a Fish-Man. He has black hair and blue skin with green spots on his forehead and shoulders, as well as fin-like ears, fins on his shoulders and a dorsal fin on the top of his head. He also has a prominent bellybutton. He wears a violet vest with a white collar and red bow tie, as well as two white cuffs on his wrists with black buttons. He wears a pair of dark blues pants with black shoes and a belt that has a golden buckle that resembles a fish. He normally wears large sunglasses which cover his scarred blind eyes.


He appears to be confident with his skills, believing he could defeat Luffy and Hancock alone in two minutes. This led to his downfall as the duo defeated him with little difficulty. He is very loyal to World and despite having abandoned him 30 years ago, he proved to still be a loyal crew member after his release. Before World's capture, he and his crewmates were like close friends and would often share their desire for freedom together while happily drinking.

Like many characters in One Piece he has a distinct laugh: "Shishishi".

Abilities and PowersEdit

As a Wotan, he has strength equal to that of a giant, and can breathe underwater like a Fish-Man.

Camouflage Air

Sebastian uses Camouflage Air.

He is blind, so he is immune to Boa Hancock's power. However, he is still able to sense the enemy and fight them with ease, indicating that either his natural adaptations as a Fish-Man allows him to fight as such, or he is possibly highly adept at using Kenbunshoku Haki to compensate for his blindness. As a false kelpfish Wotan, he is able to camouflage himself with his surroundings, making it seem like he vanishes into thin air. He is also able to protrude spikes from his body.

  • Camouflage Air (カモフラージュエア Kamofurāju Ea?): Sebastian camouflages himself to evade his opponent's attack and attack them from behind. He first uses this to evade Boa Hancock's Perfume Femur.
  • Spin Tornado (スピントルネード Supin Torunēdo?): Sebastian protrudes spikes from his body and launches himself into a vertical spin at his opponent. This was first used against Luffy, but was deflected by his Gomu Gomu no Gigant Pistol.


He wields two maces.

Fish-Man KarateEdit

He is able to use Fish-Man Karate as he was seen throwing larger versions of Uchimizu and Yabusame.



His past before joining the World pirates is unknown. He and his crewmembers were seen fighting and winning against navy and pirates alike. When the World Government finally found a way of defeating them, Sebastian is present when their captain is betrayed and shot multiple times by his own crew members. He and the others were commanded by Byojack to escape and survive.


After Byrnndi World escaped, he and his fellow crew members were present and fetched their captain with their dream ship.

When Boa Hancock and Monkey D. Luffy entered their ship, he faced them telling his captain he would defeat them in 2 minutes. He revealed to Hancock that he is visually handicapped so her powers have no effect on him. Although he put up a good fight, he is defeated by Luffy's Gomu Gomu no Gigant Pistol and is sent crashing to the island. He tries to get up but Perona shows up and uses her power to make him negative.

After the climatic battle between their captain and Monkey D. Luffy, the Marines led by Sakazuki attacked and made their ship explode. He is assumed to be killed with his fellow crew members.

Major BattlesEdit


  • Though non-canon, he is the second Wotan seen in the series, the first being Big Pan.
  • He is also the second blind character seen in the series, the first being Fujitora.
  • Sebastian's name is derived from the latin name of the false kelpfish, Sebastiscus marmoratus.
