Nami

"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 journey. 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 ginger (orange) hair and brown eyes. Many characters seem to consider her to be an attractive woman. She has a blue tattoo 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 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.

She wears a strap around her thigh with three slots in it which she keeps each pole of her bo staff and later the Clima-Tact in.

Along with Nico Robin, Usopp, Sanji, Tony Tony Chopper, and Franky, Nami is one of the smartest of the Straw Hats.

At the beginning, Nami despised all pirates. She viewed them as universally evil after losing someone close to her to pirates, only changing her mind after she met Luffy.

Nami can be seen ordering the crew to lift the mast or draw the sails. If she deems an island dangerous, she will often try to convince Luffy (usually along with Usopp and Chopper) to not go there but will nonetheless follow Luffy's orders when he demands so. She seems like a coward, but she has been referred to by multiple people being a "bold woman." Usually, she is called that when she stands up for her crew and what she believes to be right. She is aware of the dangers they face every day and has a much better understanding of the world and its more dangerous individuals than most of her crew does, though lacks Robin's knowledge on some of its other powerful figures and organizations. She can be devilish and cunning at times, and if she feels like it will even give her fights to Luffy, Zoro or Sanji. She is the only one among the crew to be visibly concerned and upset whenever their bounties go up, something the others usually react to with indifference or even joy.
