Willy

Willy (ウィリー) is a character from the fourth One Piece movie. He is an orca fishman and the captain of a crew of fishmen that compete in the Dead End Race.

Abilities and Powers
As a fishman, his physical strength is ten times that of a normal human and double that under water. Although seeing as he is captain of a fishman pirate crew and a rival of Arlong, he is likely stronger than that.

Weapons
His weapon of choice was a morning star.

History
He is an old rival of Arlong and when this was mentioned to Nami, due to her experience with Arlong, cringed at the idea he was in the race. He and his crew participated in the race with their ship, the Web Panic.

He is last seen about to battle with Gasparde and his crew. The outcome is never seen however. But since there appeared to be no damage from Gasparde's ship it can be assumed that Willy and his pirates were probably defeated by Gasparde's pirates. He is surprisingly insightful, managing to realize that Gasparde rigged the race when he sees the former marine sail off the main course.

Trivia

 * Willy's name and species may be a reference to the movie Free Willy, which starred an orca.
 * Though non-canon, Willy is the first fishman whose base species is a mammal, as opposed to a fish or cephalopod.
