The "Snake Princess" (蛇姫, Hebihime?) Boa Hancock (ボア・ハンコック, Boa Hankokku?), or "Pirate Empress" (「海賊女帝」, Kaizoku Jotei?), is a woman of extraordinary beauty, the sole female member of The Seven Warlords of the Sea, leader of the all-female Kuja (九蛇?) Tribe, and ruler of Amazon Lily (アマゾン・リリー, Amazon Rirī?), an island populated solely by women.ch.516 She believes that because she is so beautiful, anything bad that she does will be forgiven by everyone, and because of that she is not afraid to hurt pirates, Marines, and even her own people. During their childhood, she and her two sisters were sold as slaves to the Celestial Dragons, who forced them to eat Devil Fruits. She and her sisters still bear the brand of the Celestial Dragons on their backs. To conceal their shameful past from their kinswomen the sisters concocted a story about having defeated a gorgon, claiming that their strange abilities were the result of the Gorgon's Curse and that they have cursed eyes on their backs that would turn anyone who sees them into stone.ch.517,521 Hancock consumed the paramecia Love-Love Fruit (メロメロの実, Mero Mero no Mi?) which gave her the ability to turn anyone charmed by her into stone.ch.516,521 Unlike the women of the Kuja Tribe who only have Ambition, Hancock has King Ambition. Eventually, she falls in love with Luffy because of his selflessness and helps him infiltrate into the prison Impel Down to rescue his brother Ace.ch.522 Hancock also participated in the war, and she has drawn suspicion from some of the marine officials due to her secretly helping Luffy. Hancock also decreed that Luffy should recover on Amazon Lily to hide from the World Government. Her animal theme is the snake. Hancock's former bounty is 80,000,000 Berries. She is voiced by Kotono Mitsuishi in the Japanese version of the anime.
Her younger sisters both ate a model of the Snake-Snake Fruit (ヘビヘビの実, Hebi Hebi no Mi?) which are both zoan type. The middle sister, Boa Sandersonia (ボア・サンダーソニア, Boa Sandāsonia?), ate the anaconda model. The youngest sister, Boa Marigold (ボア・マリーゴールド, Boa Marīgōrudo?) ate the cobra model. These fruits' abilities allow them to turn into a snake or a snake-human hybrid of their respective models.ch.519
