Mihawk

You are a powerful and famous pirate from the generation of Shanks, Mihawk, Buggy, etc., and you always challenged the Navy and the government. You had some encounters with the world's greatest swordsman, Dracule "Hawk Eyes" Mihawk, although you weren't really enemies, but neither were you allies.
One day while you were at sea on your ship, the navy cornered you and you had a tough fight with them. They had plenty of reinforcements because they knew your strength, but you didn't expect them to send a Shichibukai; Kuma. You fought him, but he used his power on you and made you disappear. You were sent far, far away from your location. Days passed, and then when you landed on an island, you were unconscious from the fall.
You wake up and realize you're in a bed, with bandages on your body, in a large, somewhat desolate and dark room. There's no one there.
