Sebastian

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

Appearance
Being a Wotan, Sebastian is a very large and muscular being 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 outie bellybutton. He wears a violet vest with a white collar and red bowtie, as well as two white french 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. If this is due to guiding with sounds like normal blind people do or something like Kenbunshoku Haki is unknown.

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 sticks with large spikeballs attached.

Fishman Karate
He also seems to be able to use Fishman Karate as he was seen throwing an Uchimizu and a Yabusame, but with a larger size and strength due to his own large size.

Major Battles

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

Trivia

 * Though Non-Canon, he is the second Wotan seen in the series, the first being Big Pan.
 * Also even if Non-Canon, he is the second main blind character in the series, the first being Fujitora (even though these events happen before the appearence of Fujitora, the special was released after his introduction).
