Nami, the brilliant and bold navigator of the Straw Hat Pirates in One Piece, is a former thief with a tragic past who overcame betrayal and enslavement by the Arlong Pirates, now sailing the Grand Line with her crew in pursuit of her dream to chart the entire world, using her mastery of navigation and a powerful, weather-controlling weapon called the Clima-Tact—enhanced by Zeus, a sentient thundercloud—to outwit enemies and guide her friends through the most perilous seas.
