Nami (ナミ) is the crew's 18-year-old navigator and thief. She has the ability to recognize and analyze even the slightest changes in the weather up to the point of sheer intuition. She is also an excellent pickpocket. Her dream is to draw a complete map of the world. Throughout the series, Nami fights using a bō-like staff that is made up of three connectable segments. Usopp later provides her with a version of this weapon capable of controlling weather, called the Clima-Tact (天候棒, Kurima Takuto, renamed as "Climate Baton" in the English manga and as "Weather Forcer" in the 4Kids dub). Even later, Usopp augments the Clima-Tact with dials, making it more powerful.
