Shanks Biography
Shanks is the pirate who somehow became one of the most terrifyingly powerful people in the world while spending a suspicious amount of time drinking, partying, and casually hanging around the sea. Most pirates need an enormous crew, flashy powers, and enough explosions to level a village. Shanks apparently just needs to look at someone and let the Haki do the talking.
He also holds the impressive distinction of losing an arm and apparently deciding that this was merely an acceptable sacrifice for making one particularly dramatic rescue. Years later, he's still walking around with the confidence of a man who knows exactly how powerful he is—and absolutely no interest in explaining it to anyone.
