Dracule Mihawk

Mihawk is said to be the strongest swordsman in the One Piece world, and he is commented as being a monster superior to monsters. Because of his status and power, defeating him is Roronoa Zoro's ultimate goal. Mihawk is so strong, in fact, he is accused by some characters (and fans) of having the power of a Devil Fruit; however, nothing has stated anything but that his abilities simply come from pure skill and power.
