Cat Burglar" Nami is the navigator of the Straw Hat Pirates and one of the Senior Officers of the Straw Hat Grand Fleet. Following the Raid on Onigashima, her bounty was increased to Beli 366,000,000. From the Return to Sabaody Arc through the Fish-Man Island Arc, Nami's appearance has undergone a few significant changes, including her hair having grown rather long, reaching down her lower back with a single long hair strand hanging on the left side with bangs still hanging over her forehead. Her appearance has evolved, with her body curves and hourglass figure becoming more pronounced.

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 in 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, using it when fighting seriously against an opponent. When Nami faced a life-threatening situation, she managed to escape and now holds a deep distrust towards males, choosing to team up with Boa Hancock, a pirate empress of the Amazon pirates.
