When Lucci is first seen as one of the five foremen of Galley-La Company's Dock One, he appears to be a ventriloquist using his pigeon, Hattori, to speak for him. He also shows very impressive skills when he gets into a fight with Paulie and, later on, Luffy.
It is soon revealed he is the unquestioned leader of the Water 7 CP9 unit which infiltrated the Galley-La company, and perfectly capable of speaking for himself. Lucci ate the Neko Neko no Mi, Model: Leopard (ネコネコの実 モデル豹(レオパルド), Cat Cat Fruit, Model: Leopard ), which allows him to turn into a huge leopard-human hybrid and a full leopard. This coupled with his mastered martial arts style of rokushiki, makes him a resilient foe, and he has been ranked as the strongest CP9 agent by far. Lucci can perform Life Return, like Kumadori, and use it to alter his body into forms that amplify his skills in a specific rokushiki ability, though only Kami-e Form, which makes his man-beast form smaller and thinner, has been seen and arguably the main villain of the Enies Lobby Arc if not the main threat to the Straw Hats at the time.
In the anime, Lucci's backstory to his admission in CP9 is revealed by a Vice Admiral during the Buster Call on Enies Lobby. Fifteen years prior, a kingdom had 500 of its soldiers and its king taken hostage by a pirate crew, with the captain demanding to be made the new king of the kingdom. As the government saw the king beginning to admit defeat, they sent in the then thirteen year-old Rob Lucci, who mercilessly killed all 500 hostages to get to the captain, whom he killed without mercy. During this incident, he gained a back full of scars from the pirate crew's guns, vaguely scarred in the shape of the World Government's symbol. Shortly after that he became a CP9 member, and gained the reputation of being the group's most cold-hearted and efficient assassin in its entire history. As such, he is a very valuable asset to the World Government, almost to the point of legend; the other vice admirals believe that he can even survive a Buster Call attack. At the Galley-La headquarters in Water 7, Lucci effortlessly defeated Luffy in a relatively short fight. Later in Enies Lobby, Luffy chased after Lucci and initiated a second fight with him. The two engaged in an extremely long, hectic and boisterous fight in which Luffy eventually emerged victorius. Lucci respectively bested, withstood and survived Luffy's attacks and various states until he was defeated. However, it took Luffy's last bits of energy to defeat him, as Luffy was in the floor and couldn't even move. This proves how much of a monster Lucci was, but also how much stronger Luffy has become.
