Nico Robin is the archaeologist of the Strawhat Pirates and also a former member of Baroque Works as Miss All-Sunday. She is the sole survivor of the ancient civilization, Ohara. Nico Robin can use her body parts to make objects, she was almost executed by the World Government because she knew about the Poneglyphs but was saved by Crocodile’s attack on Alabasta. In reality Nico Robin infiltrated Crocodile’s organization in exchange for her life. The Straw Hats rescued her from drowning after Enies Lobby fell into water from Aqua Laguna.
Nico Robin has been known as an extremely strong woman among pirates, feared by everyone who opposed her will including all Marines that have tried to catch her and future pirate crewmate Crocodile. Her physical strength is second only to the two previous Pirate Emperors, Gekko Moriah and Marshall D. Teach (Blackbeard).
Nico Robin’s dream is to find the Rio Poneglyph which tells of an ancient weapon referred to as Pluton. She wants to use this knowledge for good by destroying the world rather than having it be misused by evil people who want to conquer it.
