Nami/Abilities and Powers

Abilities and Powers
Being the assigned navigator of the Straw Hat Crew, Nami is responsible for evaluating the directions of which their ship go as they sail further into the sea. Nami also tends to act as the crew's de facto treasurer.

Throughout most of the series up to the Alabasta arc, Nami was not as skilled in combat as most of her crew; she does not have superhuman strength, nor does she have formal training in any fighting style, although she was shown in the Water 7 arc to have decent agility, being able to jump over a gate and between rooftops. As a result, she remained a supporting member of the crew rather than a main fighter. Before acquiring the Clima-Tact and its upgrades, she possessed moderate skill with a Bo staff she used for self-defense. However, she was often outmatched by the monstrous foes they met at sea, and typically manipulated one of her crewmates to fight in her place or fled when the situation turned dangerous. With the Clima-Tact, this habit slowly began to disappear.

Though she doesn't have great physical strength, she is usually the one to give the seemingly more immature members of the crew lumps, with enough force to hurt even Luffy, especially when they do something stupid. It is suggested that after two years, her strength has greatly increased, since before the time-skip when she kicked Brook it just toppled him, but after reuniting with the crew, her kick sent him flying across the deck of the Sunny.

Navigation and Cartography Expertise
It's not hard for a fishman to research about navigation but we can't find a good navigator. I have sought navigators throughout the world but no one draws a map as accurate as her. She is very talented. Nami is a highly skilled navigator as well as a talented cartographer, to the point where Arlong considered her skills on par with the fishman "superiority" since they were superior to any fishman's. When Luffy destroys her room at Arlong Park, maps of both bathymetric and geographic nature were seen, indicating 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 the innate ability to sense changes in the weather, and can even predict the appearance of supposedly unpredictable cyclones in the Grand Line despite running a high fever. This attribute proved useful during Nami's one-on-one "fight" 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 Clima-Tact. It could be assumed that after the time-skip her navigation skills have greatly improved due to her study of the New World climate with the help of Haredas. She's also an excellent thief and pickpocket, as small items, such as keys, are stolen without the victim noticing (she is shown stealing even as a little girl). This was shown before she left her village at the harbor, stealing almost all wallets from the people saying goodbye to her while running without anyone noticing before she reveals it. She now uses this skill of hers to steal from other pirates, more often than not sneaking aboard their ship and stealing all their valuables while the rest of the crew is distracted by the fight.

Weapons
Prior to the events of Alabasta, Nami realized her shortcomings as a combatant due to lacking in a devil fruit power or training, and her staff fighting skills are adequate for fighting normal level pirates. Due to the imminent battle on the desert nation, she requested Usopp to make her a weapon. Usopp thus made the clima-tact, explaining that they do not have the monstrous strength or powers as the rest of the crew, thus their abilities would need to come from their resourcefulness and skills (hence Usopp's reliance in distance) in Nami's case her nearly unmatched skills of navigation and weather predictions. At first she read the manual the wrong way which resulted in her conjuring parlor tricks, as the episode progressed. Nami tactfully utilized the Clima Tact subtly without the enemy noticing her moves, always catching the opponent by surprise, which are astonishingly effective, thus sending her opponent flying through a few walls most of the time.

Clima-Tact


Nami relied on a standard wooden staff throughout the East Blue saga and kept it until the Alabasta arc. During that arc, Usopp invented her a weapon called the "Clima-Tact". Although the Clima-Tact initially seemed like a useless tool, Nami managed to unlock its potential and fight a major battle in a nonsupporting role, earning her first victory by defeating Miss Doublefinger. However, despite her improved fighting potential, she still stuck to the old tactics she employed before the Alabasta arc, sending in her crewmates when she sensed danger and/or running away.

Some time before or during the the Water 7 arc, Usopp improved the Clima-Tact with Dials, creating the "Perfect Clima-Tact". This new weapon was powerful enough to wipe out an entire group of Marines, and was effective enough to help Nami defeat CP9's Kalifa. Following the Straw Hat's battle with CP9 at Enies Lobby, Nami has been engaging in combat more actively, and is shown confidently brandishing her Perfect Clima-Tact at any sign of confrontation. By earning a bounty, Nami has proven herself to be more than a navigator, and with her Perfect Clima-Tact, she has grown to become a legitimate fighting pirate in the Straw Hat crew.

After the time-skip, her abilities are greatly enhanced, being able to easily destroy a bar with a lightning blast that can be compared to an attack by Enel. Whether her Clima-Tact was responsible yet is unsure. At the stand-off between Neptune's soldiers with Usopp, Brook, she wielded a black staff, possibly the upgraded version of the clima-tact with the disappearence of the balls.

Other Techniques
Though infrequent, Nami has a couple of other moves that she can use to incapacitate (in more ways than one) her opponents.
 * Shiawase Punch (幸せパンチ): a "technique" that Nami uses to dispatch people watching her bathe; she simply drops her towel, causing any male in the vicinity to collapse from a massive nosebleed. She also uses this as a get-rich-quick scheme, as she charges 100,000 to anyone who sees her doing this. This is called Happiness Punch in the FUNimation dub.
 * Impact (衝撃貝（インパクト）): Nami uses an Impact Dial to absorb attacks and then send them back at her opponents. This was shown only when she finished off Hotori with Gan Fall. Sadly though, she is not yet strong enough to do this technique without causing serious damage to her arm and great pain, which is perhaps why she hasn't used it more often. This technique retains its name in the FUNimation dub.
