Nico Robin / "Demon Child"

Nico Robin (ニコ・ロビン) is the archaeologist of the Straw Hat Pirates. She was originally introduced as the Vice President of Baroque Works known as Miss All Sunday before joining up with the Straw Hats. She ate the Hana Hana no Mi.
Nico Robin is a tall woman with shoulder length black hair. She usually wears somewhat revealing clothing (usually showing her breast cleavage, sometimes even shows her belly) that is either dark in color or consisting of leather, sometimes both. Robin sometimes wears a gold arm band with white strings attach to it and has the letter N on it which stands for her family name and has worn a cowgirl hat on numerous occasions. Robin also resembles her mother greatly, with the exception of her hair color and style. In the anime her skin tone is also slightly darker than her mother's.
The author has also replied to a fan's question to saying that right now Robin's measurements are as follows:

• Height: 188cm (6'2"), making her the third tallest member of the Straw Hat Pirates.
• Her 3 measurements are (according to Sanji) B99 W59 H89 (39"-23"-35").

According to Oda, Robin most resembles a crane, is represented by the color purple, and she smells of flowers.
