Rob Lucci is a very tall and slim, yet muscular man with arched brows and a close-shaved goatee. He has shoulder length wavy hair that is sometimes tied in a ponytail. When he isn't 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 tanktop and shoes with black toe-caps. As an assassin, he wore a neat black suit with the sleeves normally rolled up, with black leather shoes and a white tie and handkerchief in the breast pocket.
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. When he becomes a CP9 agent he is often cold and collected not caring about anyone but himself. He also considers weakness as a sin and people should die for it.
in Enies Lobby, Lucci and the rest of CP9 members witness the Strawhats arrival and their challenge to them and the World Government, much to his amusement. Luffy chases after Lucci and initiates a second fight with him. The two engage in an extremely hectic and boisterous fight from which Lucci still holds a noticeable advantage where Lucci bests, outlasts, and survives Luffy's attacks and counters with twice as much power. Luffy is later joined by Franky but even with the added reinforcement the two of them are still woefully outmatched by Lucci.
During the fight, Luffy is incapacitated and Franky is nearly killed by Lucci's Shigan Ouren until Luffy uses his Gear Second technique, to which he promptly began beating on Lucci even in his half-beast form. However, Lucci still manages to gain the advantage when the Gear Second effect wears out, leaving Luffy in the same situation. At this point, Lucci floods the tunnels with water by using Rankyaku to break the wall, to stop Luffy's crew from escaping and taunts Luffy, asking him whether he will continue to fight or rescue his friends and promptly escapes to higher ground, Luffy pursues him claiming that if he couldn't defeat Lucci, he couldn't protect any of his nakama.
The fight continues with Lucci easily countering every one of Luffy's attacks and thrashes him around so much he could barely stand anymore. Rob Lucci, confident that Luffy used up all his energy using Gear Second, remarks that he is helpless before him like so many other pirates. In response, Luffy chuckles and claims that he is going to use a different strategy and activates Gear Third with Hone Fuusen. After Luffy uses Hone Fuusen, Rob Lucci responds to this by saying "Bone?" to Luffy. He then says to Lucci that the power moves from one bone to another, and told him to watch.
He also says to Lucci that his left arm is now the hand of a giant. Rob Lucci, now seeing Luffy starting his attack, says that if he is trying to intimidate him, he needs to stop it. Luffy starts attacking using Gomu Gomu no Gigant Pistol while Rob Lucci tries to block and prevent from damaging him with Tekkai. However, Lucci got hurt in the process from the attack instead. Monkey D. Luffy, using the humongous strength of Gear Third, punches Lucci so hard that he is flung all the way onto a Buster Call ship, almost passing out in the process. Nevertheless, he takes advantage of Gear Third's lack of speed to quickly strike Luffy down with another Tobu Shigan Bachi, causing Luffy to deactivate Gear Third. He then uses Rankyaku Gaichou for the very first time in the air while Luffy is down on a Buster Call ship to finish him off, causing an explosion and cutting through steel on the ship.
Continuing the fight with his opponent, he uses Shigan Madara again, while Luffy counters it with his punches. After getting hit again by Luffy, he attempts to use Rokuougan again. Luffy, in Gear Second, tries to get out of its range and claims that he won't get hit by that attack again, but Lucci uses his tail to prevent him from escaping the technique. Determined to end the fight once and for all, Lucci channels all of his power into his next attack, the powerful Saidairin: Rokuougan, to greatly wound Luffy once more - but this ultimately proves futile and perhaps even served to weaken him further due to the energy required for the attack and the fact that it was used as a final resort.
Rob Lucci turned around after performing his ultimate attack on Luffy, but is surprised to sense that Luffy is still standing upright behind him. He turns around to see Luffy unleashing an attack. Recalling all the pain Lucci had put Robin and his friends through, Luffy unleashes a brutal Gear Second "Gomu Gomu no Jet Gatling" attack on Lucci. Rob Lucci attempts to use Tekkai to deflect the blows, but unfortunately for him, the enormous attack strikes Lucci so hard and fast that it appears he is being hit with dozens of fists at the same time. The attack smashes Lucci against and through a brick wall, leaving him unconscious and defeated.
Powers and Ablities
As one of the physically strongest characters in the series, Rob Lucci's great power is acknowledged even by the Shichibuki.Even at the tender age of thirteen, Lucci was already known to be a very capable mass-murderer, having killed 500 soldiers and a crew of pirates single-handedly.Lucci is the only person so far to single-handedly bring Luffy to the brink of death with nothing other than raw brute force. Lucci has complete mastery of Rokushi(a fighting style), having used at least one or more moves from each of the different forms, such as Rankyaku Hyoubi and Tobu Shigan: Bachi. He demonstrates this when he unveils the Rokushiki hidden technique, Rokuougan, during his fight with Luffy. The massively powerful technique is so strong that it causes severe internal injury to Luffy's body no small feat considering that he's made of rubber. With his complete mastery of Rokushiki, in conjunction with his Devil Fruit ability, Lucci proved to be a resilient and formidable foe, fighting on an equal footing with Luffy in Gear Second, and literally forcing him to exert every ounce of strength against him.
Rob Lucci ate the cat cat fruit model:leopard, a zoan-class devil fruit which allows him to transform into a leopard and a giant leopard-human hybrid. As Zoan-class Devil Fruits enhances physical capabilities the most, it is most favored by martial artists like Lucci. Also, being a carnivorous animal, Lucci is more bloodthirsty and predatory than a regular Zoan-class user, proven when he mauled Luffy as an actual leopard
