Sebastian

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

Abilities and Powers
He appears to wield two sticks with large spikeballs attached. As a Wotan, he likely has incredible strength, and can breathe underwater. He is blind, so he is immune to Boa Hancock's power. However he is still able to sight the enemy and fight him with ease. If these is due to guiding with sounds like normal blind people do or something like Kenbunshoku Haki is unknown.

He also seems to be able to use Fishman Karate as he was seen throwing an Uchimizu.

Major Battles

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