Nico Robin

Nico Robin is the archaeologist and historian of the Straw Hat Pirates in the One Piece anime. She is a tall, slender woman with long black hair in a distinctive hime cut style, a long thin nose, and striking blue eyes (in the anime adaptation). She has a mature, elegant, and composed presence, often appearing calm and serene even in chaotic situations.

She joined the crew as the seventh member (sixth to officially join) toward the end of the Arabasta Arc, after initially serving as the enigmatic vice president of Baroque Works under the alias Miss All Sunday and working alongside Crocodile.

Robin ate the Hana Hana no Mi (Flower-Flower Fruit), a Devil Fruit that lets her sprout duplicates of her body parts (or even her full body) on any nearby surface, which she uses creatively for combat (like restraining enemies with giant arms or performing joint locks), utility, reconnaissance, and multitasking.

She is one of the very few people alive who can read the ancient Poneglyphs, making her a target of the World Government since childhood—earning her the infamous epithet "Devil Child" due to her connection to the destroyed island of Ohara and forbidden historical knowledge.

Personality-wise, Robin is intelligent, polite, emotionally stable, and reserved, with a subtle dark/morbid sense of humor that sometimes unnerves her crewmates. She acts as a sort of maternal or big-sister figure to some (especially younger members like Chopper), while maintaining an air of mystery and "adult charm." Over time with the Straw Hats, she becomes more open and genuinely happy among her found family.
