What good is the treasure if I'm alone? After sharing so much of our dreams. Instead of sacrificing them and leaving with you I would rather... HAVE NOTHING AT ALL!
"Cat Burglar" Nami is the navigator of the Straw Hat Pirates and one of the Senior Officers of the Straw Hat Grand Fleet. She is the third member of the crew and the second to join, doing so during the Orange Town Arc. She is the adoptive sister of Nojiko after the two were orphaned and taken in by Bell-mère.
She was formerly a member of the Arlong Pirates and initially joined the Straw Hats so that she could rob them in order to buy back her village from Arlong. However, she legitimately joined the Straw Hats after they rebelled against and defeated Arlong. Her dream is to make a map of the entire world.
Nami is a slim young woman of average height with orange hair and brown eyes. Many characters seem to consider her to be an attractive woman. She has a black tattoo (blue in the anime) on her left shoulder, which represents mikan, and pinwheels (a homage to Bell-mère, Nojiko, and Genzo, respectively), where she used to have a tattoo for being a member of Arlong's crew.
Her overall physique matures slowly throughout the series and then suddenly during the timeskip (though this is most likely a simple change in style of artwork). Her fashion frequently changes as does her hair style. Many of her shirts feature four-letter words, such as "Gold" or "EVIL", similar to a shirt that Bell-mère once wore that had "MACE" on it. On her left wrist, she wears the Log Pose, which she needs in order to be the navigator of the ship, and a gold bracelet, given to her by her sister, Nojiko. After the Arlong Park Arc, Nami frequently changes into a variety of clothes in the series for each arc, and usually pairs her tops with skirts that have two rings on the sides. Her trademark shoes are orange high-heeled gladiator sandals. Nami wears some form of high heels in every arc, and while they do make her taller, they do not seem to affect the way she walks or her speed. Though she tends to style her hair neatly, occasionally, a hair on top of her head may form into a messy cowlick.
Before the Syrup Village Arc, Nami wore her trademark orange miniskirt with two white rings on each side filled in with orange or brown in their centers and shirts with short sleeves that were long enough to hide her tattoo on her left shoulder that showed that she was a member of the Arlong Pirates. She also had short hair with a particularly curled strand over the left side of her face.
During the Arlong Park Arc, Nami wore a green camisole with dark green flower shapes, tight black pants with two yellow rings on the sides, and light orange high-heeled sandals. Nami temporarily put on a glove to hide the fact she had stabbed her hand when pretending to murder Usopp but quit wearing it once the truth was exposed. She also wore Monkey D. Luffy's straw hat for a while before it was later returned to him. After the arc, she wore a plain white shirt with a blue miniskirt with two white rings on the sides. For the first time, she wore sleeveless clothing that exposed her Arlong Pirates tattoo, but later, in a fit of uncontrollable rage, Nami later stabbed her tattoo relentlessly in an attempt to destroy it, until Luffy stopped her by force. She eventually asked Dr. Nako to remove it, but the doctor couldn't erase it entirely, leaving a visible scar; the scar had been caused from both Nami repeatedly wounding herself in the arm and the indelible nature of the tattoo. Nami chose to cover it up by getting a new tattoo which was a cross between a tangerine and a pinwheel, in honor of both Bell-mère and Genzo. Nojiko also gave her a gold bracelet as a keepsake before she departed from her home, which Nami began to wear regularly on her left wrist ever since.
From the Return to Sabaody Arc through the Fish-Man Island Arc, Nami's hair has grown rather long, which reaches her lower back. A single long hair stand hanging on the left side with bangs still hanging over her forehead. Her breasts have also grown much larger/rounder similar to Nico Robin's, but apart from this, her appearance has not changed much, save for the fact that both her body curves and hourglass figure have become more pronounced. Oddly, Nami's face is now drawn to look younger with her eyes bigger (with the irises now showing), droopier and placed lower on her face; though this may be from the art style evolving. She also has grown slightly taller. After the timeskip, her outfit consists of a revealing green and white bikini halter top, tight low-rider jeans (that expose a bit of her hips and rear), orange high-heeled sandals and a pair of pearl-like earrings that she constantly wears. Ever since arriving to the New World, Nami sports a new belt that is black with a "Beli" symbol on it where she can also keep the pieces of her Sorcery Clima-Tact on the right side and puts the belt around her waist when she is fighting seriously against an opponent.
Being the assigned navigator of the Straw Hat Pirates, Nami is responsible for evaluating the direction that the ship goes as they sail further into the sea. Nami also tends to act as the crew's de facto treasurer, managing the crew's money and allocating spending money whenever they arrive at a new location.
Nami is an accomplished and agile polearm user. Knowing she lacks the raw strength of most of her crewmembers she uses her cunning and specially designed weapons to combat opponents who are her physical superiors. While she tries to avoid combat as much as possible, when the need arises Nami gives her all in battle and has defeated some fearsome fighters.
Despite being one of the weakest members of the crew, Nami nonetheless possesses a strong enough will to be able to withstand a burst of Big Mom's Haoshoku Haki just like the rest of her crewmates.
Nami is a highly skilled navigator and an extremely talented cartographer. Arlong considered her skills on par with the fish-men "superiority" since they were superior to any fish-man's. When Luffy destroyed her room at Arlong Park, both bathymetric and geographic maps were seen, proving that Nami has a wide variety of cartographic skills.
She is capable of formulating advanced equations in mere minutes to predict a precise course of action, although she usually needs to write the equations down on a physical medium when formulating them. She has a supernatural ability to sense changes in the weather, "with her body" according to Vivi, and can even predict the emergence of supposedly unpredictable cyclones in the Grand Line, undeterred even by a high fever. This ability, combined with her years of knowledge in cartography and navigation, has also made Nami an expert in meteorology. Not only has she been shown to continuously and accurately predict various normal weather conditions, but she is also capable of predicting and handling the almost unnatural, unpredictable, and inexplicable weather conditions of the Grand Line, being more than capable of navigating through these conditions.
This attribute proved useful during Nami's one-on-one altercation with Enel, where she managed to deflect several of the Goro Goro no Mi user's lightning-based attacks using only "Thunder Balls" from her first Clima-Tact. It could be assumed that after the timeskip, her navigation skills have greatly improved due to her study of the New World climate with the help of Haredas, as even Caribou immediately recognized and praised her skills as a navigator during their descent to Fish-Man Island.
Apart from her navigational skills, Nami has also proven herself to be an excellent thief and a master pickpocket. She is able to take small items, such as keys, without her victims noticing, a skill she honed from a young age. Her most notable thieving feat was shown just before she left her village. At the harbor, she stole numerous wallets from the villagers saying goodbye to her while she was running past them, and among the villagers and the Straw Hats, plus Johnny and Yosaku, no one noticed until she revealed what she had done.
She now uses this skill to steal from other pirates, and occasionally government employees, more often than not sneaking aboard their ship or base and taking all their valuables while they are distracted by some fight. Her skill at thievery has even been recognized by the World Government and has earned her the epithet "Cat Burglar".
Nami's fighting style focuses mainly on using the Clima-Tact to manipulate the weather of her surroundings, also known as the "Art of Weather". When combined with her immense knowledge of meteorology and weather systems, this ability can be used for devastating results.
Nami first gained the ability to manipulate the weather when Usopp gave her the Clima-Tact. The flaw with his invention, however, was that it was primarily for party tricks. Regardless of this conflict, due to her expertise she was able to combine several of its functions in order to pull off dangerous and useful techniques, like creating a mirage of herself, (Mirage Tempo) in order to distract her opponent, and a powerful lightning cloud (Thunderbolt Tempo), which was used on Miss Doublefinger, who thought she was a magician.
After the Skypiea Arc, Usopp improved the Clima-Tact with Dials, creating the Perfect Clima-Tact. This improvement gave her much greater power over the weather, allowing her to easily pull off stronger and newer versions of the tricks she could do with the Clima-Tact, like creating duplicates of herself using mist (Mirage Tempo: Fata Morgana). This weapon was also powerful enough to allow her to wipe out hordes of Marines with Thunderbolt Tempo and defeat CP9's Kalifa with Thunder Lance Tempo. There was still a flaw in its use, however, as Nami was unable to properly control the lightning and her allies would sometimes sustain collateral damage.
After the timeskip, her abilities are greatly enhanced, being able to easily destroy a bar and a submarine (and harm the occupants of both) with lightning blasts that can be compared to an attack by Enel. At the stand-off between Neptune's soldiers with Usopp and Brook, she wielded the upgraded version of the Clima-Tact with the disappearance of the balls, which she now calls the Sorcery Clima-Tact. When the Straw Hats arrived at Gyoncorde Plaza, Nami's "Mirage Tempo" was shown to have improved to the point of making herself appear completely invisible, and she was also able to shoot a powerful gust of wind she named Gust Sword to easily dispatch a fish-man.
She can now use and create weather in more creative ways, like launching an egg which hatches to release a large thundercloud that she can then take control of in order to strike down her opponent(s), which she calls "Thunder Breed Tempo", and creating an orb at the end of one of the three segments of her Clima-Tact which possesses enough heat to melt snow and harm a snow woman like Monet (Heat Egg). This new Clima-Tact has also been proven to not only be useful for battle situations, but regular daily uses as well, such as taking showers (Shower Tempo) and making paths for travel with sea clouds (Milky Road). The latter is an achievement of its own as sea clouds were shown not to be produced in the Blue Sea.
