Boa Hancock is the captain of the Kuja Pirates in One Piece, and she is a former Warlord of the Sea. Boa fought in the Summit War against the Whitebeard Pirates, and she managed to survive without any injuries, which is a big feat considering the quality of her opponents.
After the Shichibukai system was abolished, Boa Hancock lost all her privileges and once again became an ordinary pirate. The Navy wasted no time in surrounding Amazon Lily in an attempt to capture her, however, Boa wasn't ready to go down without a fight. Boa has a vast array of abilities, which makes her one of the strongest One Piece characters.
8 Mero Mero No Mi
The Mero Mero no Mi is a paramecia-type devil fruit, which allows its user to turn any object into stone. The devil fruit relies on Boa's ridiculous beauty, which evokes the feeling of lust in her opponents. This makes it extremely easy for Boa Hancock to use her powers on them and turn them into stone.
It is nigh impossible to avoid the attacks of Hancock's devil fruit as almost every person is beguiled by her charms. Despite making very limited appearances in the series, Boa Hancock has shown off some of her attacks, which gives the audience a good idea of how powerful she really is.
7 Mezameyo
Most of Boa's attacks are puns related to captivity, and Mezameyo is no different. It is an attack that does not hurt the opponent; instead, Boa uses it to undo the petrification. In this attack, Boa blows a kiss over the target, which covers them with small hearts and restores them to their previous state.
Mezameyo literally means "awaken," which is a pun pertaining to freedom. In this case, the target is essentially freed from the state of petrification.
6 Mero Mero Mellow
This is Boa Hancock's signature technique that she uses in almost every fight. To use this technique, Boa joins her hands together to form a heart and then shoots a beam from it. The beam affects every person who has impure thoughts about her and turns them to stone immediately.
Once the target is turned to stone, they are completely at the mercy of Boa, and she can take her time to finish them off. The first person who was unaffected by this attack was Monkey D. Luffy, and it surprised all three Gorgon Sisters.
5 Pistol Kiss
Pistol Kiss is a long-ranged attack that was used by Boa Hancock against Luffy. The attack is a combination of Boa's devil fruit and Armament Haki. She blows a kiss and creates a heart-shaped bullet, and then she uses her index finger to aim at her target.
Boa has only used this attack against Luffy in an attempt to stop him from escaping. Since the attack was only ever used on Luffy, it is unknown if it is just used hurt the opponent or if it also has petrifying effects.
4 Perfume Femur
Perfume Femur is a close ranged attack. Boa spins rapidly while on her hands to land multiple kicks. The pace of her attacks makes it difficult for her opponents to dodge them. The unique thing about this attack is that it affects both living and non-living objects.
Boa is able to turn them into stone by making the slightest contact with them and the force of her kicks is able to break the petrified objects. Another special thing about this attack is that it only affects a certain area of the body. Basically, any place where Boa lands her kicks turns to stone. This attack has its disadvantages as the opponent can still move and launch a counter-attack against Boa.
3 Perfume Femur Magna
This is a better and stronger version of the regular Perfume Femur. Boa has only used this attack against Douglas Bullet in One Piece: Stampede. In order to increase the power of her attack, Boa runs toward the opponent and connects with a powerful kick that is enough to make them recoil.
The attack's petrifying properties are not shown, but considering it is a very area-specific attack, the affected area would be too small.
2 Slave Arrow
Slave Arrow is another long-ranged attack that has been used multiple times by Boa Hancock. In order to perform the attack, she needs to breathe in deeply which allows her to create a huge heart. She then pulls the heart, and it results in the creation of hundreds of arrows, and their tips are also shaped like hearts.
These arrows petrify the target as soon as they make contact. The enormous number of arrows released are extremely tough to dodge and on most occasions, Boa will successfully hit her enemies. The technique also brings any moving bodies to a stop, which can prove to be useful in certain situations.
1 All Three Haki Types
Boa Hancock ​​​didn't become a Warlord of the Sea just by relying on her devil fruit. She is able to use all three types of Haki, which makes her a part of a very special list. Boa Hancock hasn't had the opportunity to use Haki in her fights so far, but considering the fact that she is from the prestigious Kuja clan, it is possible that her Haki is very refined, and she can use its advanced forms as well. It won't be long before Boa Hancock gets involved in the final saga, and fights fearsome foes.
