Rob Lucci is the strongest member of the CP9 operating undercover to obtain the Pluton blueprint from Iceburg. Introduced as one of the five foremen of Galley-La Company's Dock One, he was a sawyer, treenail, and bolt specialist. He is one of the main antagonists of the CP9 Saga, specifically the Water 7 and Enies Lobby Arcs.
Appearance
Rob Lucci is a very tall and slim, yet muscular man with arched eyebrows and a close-shaved goatee. He has shoulder length wavy hair that is sometimes tied in a ponytail. When he is not fighting, his pet pigeon Hattori is usually perched quietly on his right shoulder. He has a tattoo of a crossed-out square on each upper arm, as well as five cannonball scars on his back in the shape of the World Government symbol.
He wore a large black top hat with a sepia band until he lost it during his fight with Luffy. As a shipwright, he wore brown trousers with caramel suspenders over a white tank-top and shoes with black toe-caps. As an assassin, he wore a fancy black suit with the sleeves normally rolled up, with black leather shoes and a white tie and handkerchief in the breast pocket.
Lucci was drawn as a child by Oda after a fan asked to draw the CP9 members as children. Oda drew young Lucci with the kanji for "peace" (平和 heiwa?) on his shirt, which possibly suggests that the branch Lucci is holding is an olive branch in tribute to the type of branch held by white doves (in this case Hattori) as a sign of peace.
The anime had also portrayed Lucci as a teenager in its rendition of his past story. Though the two portrayals of Lucci are meant to be him, they have different styles to them, mostly because Oda's version was drawn after the anime had already depicted him and not just because they show him at two different ages. Note that Oda did depict the silhouette of thirteen-year-old Lucci from the backside, though only briefly - this most likely is where the anime design for him originates.
In CP9's Independent Report, he wore a light spotted shirt with a black coat over his shoulders and had bandages over his forehead and chest from his fight with Luffy and let his hair fall freely.
Personality
Galley-La
During the time he was in Water 7 as a carpenter, Rob Lucci never spoke, preferring to instead talk through his pet pigeon, Hattori, using ventriloquism. However, after he revealed himself to be a CP9 agent he spoke normally, with Hattori becoming a regular pigeon that displayed some human qualities. Hattori always rides on Lucci's shoulder until Lucci begins fighting, at which point he will fly overhead until the battle is over. Lucci seems to have a rivalry with Paulie, and often chides him for having money problems. Because of this rivalry, the two often fight; however, the matches generally end before there is a victor. Other than this, however, Lucci appears to be very distant from everyone else, including the other foremen and Iceburg.
CP9
Lucci comes off as a cold and collected CP9 agent, almost never displaying any emotions (nevertheless even he displayed shock at the knowledge that Franky had the Pluton blueprints the whole time, and is shown smirking when convincing Kaku and Kalifa to eat Devil Fruits as well as when he and Spandam realized Luffy was following them, probably because of his lust for battle). In spite of his seeming lack of emotions, he does not like being insulted. During his fight with Luffy he did not pay attention to Usopp, until he started to insult him. An example is the brutal assault on his friend of five years, Paulie, whom he even tried to kill after the CP9's identities had been revealed. He also states that he feels no true bond with the city he's lived in for five years, and he seems to have no feelings for his fellow CP9 colleagues, least of all Spandam.
Interestingly enough, he does react rather violently if anyone calls him a gakki (slang in Japanese for kid or brat), responding with a kick and a retort both times after Iceburg and Franky referred to him as such. He finds it offensive when someone speaks weakness around him, and going as far as to dismiss a new colleague by presumably killing him for being weak. The reason that he killed the five hundred soldiers in his past was due to another belief of his - the belief that weakness is a sin. He also believes if he is involved then the situation means blood will be drawn and that he also does not have to accept the views and ideals of his superiors as long as he completes his missions efficiently.
In combat, he is a very violent fighter, and seems to derive amusement and gratification from inflicting physical and emotional pain on others, making him a typical sadist. These scenes, along with when he anticipates battle, are the only times where he seems happy at all. In the Tower of Justice at Enies Lobby, he reveals that he only joined the World Government so he can be legally allowed to kill people. An example of Lucci's lust for violence is when he compromised the mission of bringing Robin to the Gates of Justice by allowing Monkey D. Luffy to tail him, for the sole purpose of having a battle, smirking when Luffy burst through the door. Lucci's violent and cruel nature is also shown when he goes into full-beast mode during battle, in order to attack Luffy more violently. Another example of his sadism is when Lucci flooded the underwater passageway to the Gates of Justice in an attempt to kill the Straw Hat crew members in the passageway, because he wanted to eliminate Luffy's chances of having everything just to anger him.
Despite all this apparent lack of morality, he has displayed some, if very little, sympathy for those he dubs innocent; when the Candy Pirates are attacking a small village, he quickly dispatches the captain to save the people, though his demonstration of Absolute Justice later prompts him and his comrades to leave. This shows that deep down, he's not completely heartless.
