Willy

Willy is unique among One Piece characters as a fish-man whose base creature is an orca, a mammal rather than a fish or cephalopod. He keeps a helmet on his head and drapes thick golden chains across his throat. His shirt is orange, broken up by bold black stripes.

A long-running grudge against Arlong defines much of Willy's outlook, and the rivalry between the two worried Nami when it came up. He proves perceptive as well, piecing together that Gasparde had tampered with the race once he caught sight of the ex-Marine breaking off from the proper course.

His fish-man heritage grants him roughly ten times the muscle of an ordinary person, a figure that doubles once he submerges. Leading his own crew of fish-men and standing as an equal to Arlong implies he ranks above the typical fish-man in raw power. In combat he swings a morning star. He raced aboard the vessel known as the Web Panic, and his last appearance had him squaring off against Gasparde and his crew, though that clash was never shown on screen.
