Nami

Nami (Japanese: ナミ; [na̠mʲi]), also known as "Cat Burglar" Nami, is a fictional character in the One Piece franchise created by Eiichiro Oda. The character made her first appearance in the 8th chapter of the series, which was first published in Japan in Shueisha's Weekly Shōnen Jump magazine on September 15, 1997. She is based on Ann and Silk, two characters from Oda's previous manga Romance Dawn. She is introduced as a thief and pickpocket who possesses cartographical, meteorological, and navigational skills. At first, she is a subordinate of the fishman Arlong, until she is eventually freed of this service and permanently joins Monkey D. Luffy. She is the third member of the Straw Hat Pirates and the second to join.

In the series, Nami is the Straw Hat Pirates' navigator, who dreams of drawing a map of the entire world. Despite her initial distrust of pirates, Nami eventually changes her mind after being around Luffy and the rest of the crew. Nami is depicted as an intelligent girl who is obsessed with obtaining money. She is able to use her three-sectioned staff and her climate skills to create powerful attacks; the most prominent of these staff weapons is the Klima-Tact, in which she manipulates the climate to create weather-based attacks.
