Sebastian

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

Appearance
As a Wotan, Sebastian is very large and muscular, about the size of a small giant but with the physical traits of a Fishman. 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.

Abilities and Powers
As a Wotan, he has strength equal to that of a giant, and can breathe underwater like a Fishman.

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 Fishman 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): 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): 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.

Weapons
He wields two maces.

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

Major Battles

 * World Pirates vs. Marines and World Government
 * Sebastian vs. Luffy and Boa Hancock (interrupted by Perona)

Trivia
