Character description
Nico Robin is a tall and slender young woman with black hair that reaches slightly past her shoulders and eyes with dark, wide pupils (her eyes are brown in the manga; while in the anime they are blue). She also has a long, thin and defined nose. Robin has a slightly dark skin tone unlike in the manga where it is slightly lighter. Robin also greatly resembles her mother with the exception of her hair color and style as well as having a slightly darker skin tone than her. Robin also has very long limbs especially her legs, contributing both to her fighting skills and overall height. Robin seems to be fond of revealing outfits, she is frequently seen wearing somewhat revealing clothing that are either dark in color (often black or purple) or consists of leather (sometimes both). She is also fond of high heels. After the timeskip she is mostly seen in a long pink sari-like skirt with a partially-zipped purple leather vest with a V-neck line similar to Boa Hancock's and a white rose printed on her left breast near the shoulder that exposed her stomach, pink high heeled pumps, and a pink backpack. She has sunglasses which she mostly hangs on her forehead. Nico Robin is the most serene of the all the Straw Hat Pirates and is rarely seen acting comically. She is much smarter than Nami and treats Luffy with more respect than the rest of the crew, even when he acts impulsively, to which she often laughs at that. Together with Roronoa Zoro, she is one of the members that support Luffy's decisions unconditionally.

Nico was born to a family of archaeologists consisting of her mother Nico Olivia and an un-named Man. Her mother went out to sea to find the True History when Robin was just 2 years old, to fulfill her husband's dream, leaving her in the care of her older brother and his wife, Roji (Olvia's sister-in-law). Roji mentally and physically abused Robin stating that she did not belong to her family and was never wanted, her Flower-Flower Devil Fruit powers also scared the other children. Robin later wanders into the Tree of Knowledge and was allowed to read the books held within on Clover's invitation who knew her mother and went on to take care of her. When she was 8 years old she pasted an archaeology test and became a scholar at the Tree of Knowledge, just like her mother she wanted to find the True History much to Clover's dismay.
