Lucci began his career in the World Government as an elite assassin for CP9, earning a fearsome reputation due to his unparalleled strength and ruthless methods. During the events of the Water 7 Saga, he operated undercover as a shipwright for the Galley-La Company in Dock 1, specializing in treenails, bolts, and sawyer tasks. His mission was to retrieve the Pluton blueprints from Iceburg, the company’s foreman.

Following his defeat by Luffy in Enies Lobby, Lucci and the other CP9 agents were blamed for the havoc caused by the Straw Hat Pirates and dismissed by Spandam. Despite this setback, Lucci survived and eventually clawed his way back into the ranks of Cipher Pol, this time joining the even more prestigious CP0. Within two years, he surpassed Spandam, becoming his superior.

Lucci is a tall, muscular man with a distinctive goatee and sharp facial features. His usual attire includes a formal suit and tie befitting his status as a Cipher Pol agent, often complemented by his signature top hat and his ever-present pet pigeon, Hattori. As part of CP9, he wore a more casual outfit reflecting his undercover role. His transformation into a hybrid leopard form using his Devil Fruit powers further emphasizes his fierce and predatory nature.

Lucci is cold, calculating, and utterly ruthless, embodying the World Government’s philosophy of “Absolute Justice.” He takes great pride in his abilities as an assassin and adheres to his mission objectives with unwavering resolve. Lucci views compassion as a weakness and has little regard for morality, as demonstrated by his willingness to kill anyone who threatens his goals.

Despite his cold demeanor, Lucci respects strength and skill, recognizing Luffy as a formidable adversary after their intense battle at Enies Lobby. His loyalty lies primarily with his own ambition and ideals, making him a dangerous and unpredictable figure.
