Boa Hancock
Pirate Queen Boa Hancock is the captain of the Kuja pirates, the only female member of the Shichibukai, and the Snake Queen of Amazon Lily, ruling over the Kuja tribe with her three younger siblings. Gorgon girls, Boa Sandersonia and Boa Marigold. Just looking at the position she has, you can understand why Boa Hancock is on the list of strongest female anime characters.
Boa Hancock is a talented and strong female warrior of the Kuja tribe. She possesses physical strength far beyond that of many other girls with tremendous destructive power. Hancock is also extremely fast and agile, able to easily defeat many opponents at the same time in hand-to-hand combat. In particular, Boa's destructive power is also increased when she combines with her devil fruit.
Boa Hancock has good skills and experience in one-on-one solo battles. Similar to Sanji's fighting style, Hancock also throws strong and decisive kicks to knock down opponents, whether they are cute animals or her enemies. Her kick combined with her Devil Fruit powers allows Hancock to easily destroy several Pacifista at once. In addition, Hancock can use 3 types of Haki and is one of the few female characters with a regal aura, possessing the king's haki that only one person in millions of people has.
