Nami

Nami, known as the "Cat Burglar," serves as the navigator of the Straw Hat Pirates and holds the rank of Senior Officer within the Straw Hat Grand Fleet. She stands as the third member to join the crew and was the second addition, enlisting her services during the Orange Town Arc. Following the tragic loss of her family, Nami became the adoptive sister of Nojiko, with both being orphaned and taken in by Bell-mère. In her earlier days, Nami found herself reluctantly aligned with the Arlong Pirates and initially sought to join the Straw Hats with the intention of robbing them to secure funds for her village's liberation from the clutches of Arlong. However, her true allegiance solidified when the Straw Hats led a rebellion against and vanquished the oppressive Arlong. Nami's cherished dream revolves around creating a comprehensive map of the entire world.

Throughout her journey, Nami has accrued bounties, initially marked at 16,000,000 Beli following the Enies Lobby raid. Her reputation continued to escalate, leading to a subsequent bounty increase to 66,000,000 Beli following the Dressrosa Arc and a further elevation to 366,000,000 Beli post the Raid on Onigashima. As the designated navigator of the Straw Hat Pirates, Nami shoulders the crucial responsibility of charting their course through the vast oceans. She also fulfills the role of the crew's unofficial treasurer, managing their finances and allocating resources upon reaching new destinations. Nami demonstrates proficiency as a nimble and resourceful polearm wielder. Recognizing her comparative lack of raw physical strength among her crewmates, she relies on her cunning strategies and specially designed weaponry to confront adversaries who outmatch her physically. While she generally seeks to avoid combat whenever possible, Nami exhibits unwavering resolve in battle when the situation demands it, successfully overcoming formidable opponents.

Despite being considered one of the crew's less physically robust members, Nami possesses a formidable willpower, enabling her to withstand Big Mom's Haoshoku Haki, a feat she shares with her fellow crewmates. Her combat style centers on the utilization of the Clima-Tact, a versatile weapon that allows her to manipulate the surrounding weather—an ability known as the "Art of Weather." Combining her mastery of meteorology with this weapon, Nami wields it to devastating effect. Initially created by Usopp, the Clima-Tact had limitations as it was primarily designed for entertainment purposes. Nevertheless, Nami's expertise enabled her to amalgamate its functions, leading to the execution of potent techniques. Notable examples include creating mirages (Mirage Tempo) to confound her opponents and summoning a formidable lightning cloud (Thunderbolt Tempo) used effectively against adversaries like Miss Doublefinger.

After capturing Zeus, a thundercloud Homie, Nami gained the capability to store him within her Clima-Tact. This partnership allowed her to harness Zeus's power, enhancing her Clima-Tact abilities for the execution of destructive lightning attacks. Although Zeus was eventually reclaimed by Big Mom, Nami's resourcefulness led to her hearing her Clima-Tact speak to her and discovering that Zeus's essence resided within the weapon. With the Clima-Tact evolving into a sentient weapon, Zeus could transform it into combat-oriented forms, enhancing Nami's offensive capabilities. Moreover, Zeus could temporarily transfer his consciousness to the clouds summoned by Nami, granting her control over her attacks, rendering them more challenging to evade. This newfound power enabled Nami to unleash lightning attacks of unparalleled potency, ultimately leading to her triumphant defeat of Ulti, one of the immensely durable Tobiroppo.
