Cavendish, famed as "Cavendish of the White Horse" and the "Pirate Prince," commands the Beautiful Pirates. Once prince of the Bourgeois Kingdom, his exile followed widespread refusal of marriage proposals by women captivated by him; this departure granted him 74 loyal followers and 500,000,000 berries. His piracy career, sparked by exile, earned him notoriety as a Super Rookie. He possesses a lean, muscular frame standing 208 cm tall, with long blond hair and bright sky-blue eyes. His signature attire features a black musketeer tricorne hat boasting a large aqua-blue plume, a ruffled white V-neck shirt, and a coat draped over his shoulders. He expertly wields the sword Durandal, carried on his left hip. His appearance is frequently described as overwhelmingly attractive, often causing onlookers to faint. Cavendish exhibits extreme narcissism, vanity, and an insatiable desire for attention. He harbors deep resentment toward the Worst Generation for eclipsing his fame, fueling initial antagonism like his attempt to kill Monkey D. Luffy at the Corrida Colosseum during the Mera Mera no Mi contest. Despite this arrogance, he demonstrates honor, defending the gladiator Rebecca from public scorn and showing loyalty to allies. He is deeply protective of his horse, Farul, and holds animals in high regard. Roses are his favored food, often consumed during conversations. A defining trait is his dissociative identity disorder, manifesting as the alter ego Hakuba. When Cavendish sleeps, Hakuba assumes control—a bloodthirsty entity with demonic features, white eyes, and a permanent sneer. Hakuba operates with extreme speed and lethality, indiscriminately defeating opponents. Cavendish can suppress Hakuba through willpower but struggles for control while awake, resulting in a "half-and-half" appearance. Hakuba's abilities significantly augment Cavendish's combat prowess, contributing to his initial 280,000,000 berry bounty. During the Dressrosa Arc, Cavendish transitions from antagonist to key ally. Witnessing Luffy’s determination and Usopp’s bravery, he abandons his grudges against Luffy, Roronoa Zoro, and Trafalgar Law. He aids in defeating the Donquixote Pirates and pledges loyalty to Luffy post-battle, becoming captain of the first ship of the Straw Hat Grand Fleet. His bounty subsequently rises to 330,000,000 berries. Post-Dressrosa, he commits to protecting Law if needed and displays strategic perceptiveness, recognizing the global repercussions of Doflamingo’s defeat.
