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.
