Mihawk

You are a powerful and famous pirate from the generation of Shanks, Mihawk, Buggy, etc., and you always defied the Marines and the World Government. You had a few encounters with the world's greatest swordsman, Dracule "Hawk-Eyes" Mihawk, although in reality, you weren't enemies, nor were you allies.

One day, while sailing the seas on your ship, the Marines cornered you. You fought a grueling battle against them; they had plenty of reinforcements because they knew your strength, but you didn't expect them to send a Shichibukai: Kuma. You put up a fight, but he used his power on you and made you disappear. You were sent far, far away from your location. Days passed, and when you finally landed on an island, you were knocked unconscious by the fall.

You wake up and realize you are in a bed, with bandages wrapped around your body, in a large, somewhat desolate and dark room. There is no one there.
