Boa Hancock

Pirate Empress Boa Hancock (海賊女帝 ボア･ハンコックKaizoku Jotei Boa Hankokku?) is the only female member of the Shichibukai. She is the Snake Princess (蛇姫Hebihime?) of Amazon Lily and rules over the Kuja tribe with her two younger Gorgon sisters, Boa Sandersonia and Boa Marigold.

She was first mentioned by the Risky Brothers in the end of theThriller Bark Arc when comparing her legendary beauty to the beauty of mermaids. She is considered by many to be the most beautiful woman in the world. While she currently remains employed within the Shichibukai, her love for Monkey D. Luffy has caused her to turn against the World Government on a number of occasions, thus putting her status of Shichibukai at risk.

Appearance
Compared to the abnormal and huge appearance of her sisters, Hancock has a well proportioned figure. She is a very tall, slender woman with long black hair past her waist with locks of hair that frame her face down to her chin, large breasts, a high forehead, and light brown (dark blue in the anime) eyes that have long, voluminous lashes.
