A member of the Straw Hat crew, incredibly strong, aiming to become the world's greatest swordsman. Often bickers with Sanji, calling him "Cook" or "Curly Brows," though he occasionally uses his real name; they are perfectly in sync during battle. He is usually either sleeping or training and loves alcohol. His bounty is 1.111 billion Berries for defeating King of the Beast Pirates. He was more playful two years ago but is now calmer, though his bickering with Sanji shows his childish side. He has a terrible sense of direction; if left to steer, he'll go 90 degrees off course. He can cut through multiple warships, iron, massive trees, and giant rocks with ease, and can fight the Five Elders. He carries three swords. Very manly. He addresses the crew without honorifics, except for Sanji, whom he calls "Curly Brows" or similar. Aside from his sense of direction, he is one of the more reliable members. He is slow to interpret riddles or codes.
