In the world of One Piece, there is no shortage of powerful individuals. Monkey D. Luffy, his Straw Hat crew, and the enemies they go up against all possess monstrous strength — especially following the show's two-year timeskip. While most of the series' strongest heroes and villains are male, the series benefits from plenty of powerful women too.
Although outnumbered, there are several females in One Piece who can give their male counterparts a run for their money. On the one hand, there are females whose powers are well known. On the other, some females are known to be powerful, but their full strength remains a mystery. Whether they're skilled swordsmen or possess a powerful Devil Fruit, One Piece is filled with strong female characters that consistently impress fans.
Updated on April 13, 2023 by Kennedy King: One Piece's massive cast of characters grows larger with each passing arc. The New World has debuted some of the strongest pirates, marines, and revolutionaries in the entire series, and as a result of the Raid on Onigashima, the pecking order among its strongest female characters has significantly shifted.
This article contains spoilers from the One Piece manga.
20 Kalifa
The Cipher Pol organization handles the World Government's most covert operations, and as a result, its members are among the most lethal in all of One Piece. Although most of their members seem to be male, one female figure stands out as an exceptional member of its ranks: Kalifa.
Kalifa first appears in the Enies Lobby arc as part of the CP9 assassination branch. After being defeated by the Straw Hat Pirates, she and the other members of CP9 are brought into a new organization — CP0, a group that answers directly to World Nobles. This group's agents all know Observation and Armament Haki, which makes Kalifa a dangerous opponent given her preexisting Devil Fruit and Rokushik-related abilities.
19 Tashigi
As a member of the Marines, Tashigi's importance to the plot has slowly started to fade as the series has shifted to all-out pirate warfare with the Four Emperors. It also doesn't help that she's managed to lose a number of her bigger fights, but that doesn't change the fact that she's one of the stronger female characters in the series.
Her skill with a sword may be matched by samurai like Zoro, but that isn't an insult in the least. Few can match him in the ways of swordsmanship. Tashigi still has impressive feats, such as deflecting away a cannonball and taking down fodder opponents in mere seconds.
18 Boa Sandersonia
Amazon Lily is an island almost exclusively comprised of females, so it should come as no surprise that the location is home to some of the strongest women in One Piece. One of these women, Boa Sandersonia, is the middle child of the Three Gorgon Sisters, and alongside her siblings, she protects Amazon Lily from any would-be evildoers.
Sandersonia doesn't often have the opportunity to demonstrate her talents, but considering her ability to use Armament and Observation Haki, she's certainly competent in the New World. Her Devil Fruit — the Snake-Snake Fruit: Model Anaconda — is a quality Zoan-type, lending even more credence to her abilities as a fighter.
17 Boa Marigold
Like her siblings, Boa Marigold helps protect the island of Amazon Lily as one of the Three Gorgon Sisters. However, there is a solid argument that she is even stronger than her older sister, Sandersonia. Marigold wields poison and elemental abilities that are unique to her Devil Fruit, providing her a natural advantage in combat against most opponents.
In addition to Marigold's Snake-Snake Fruit: Model King Cobra-related abilities, she also wields Armament and Observation Haki. These traits, coupled with the fact that she withstood a blast from Monkey D. Luffy's Conqueror's Haki, easily slot her among the New World's strongest pirates.
16 Hina
Admittedly, Hina doesn't play a major role in any of One Piece's major narrative arcs. However, that doesn't mean that the Marine rear admiral is without combat ability — in fact, she's demonstrated herself to be capable more times than most members of the World Government.
Hina's Devil Fruit, the Bind-Bind Fruit, is a Paramecia-type that allows her to produce iron bindings that restrain prisoners. It comes in handy on multiple occasions, and in two separate instances, these powers help her subdue Mr. 2 (also known as Bon Clay). As a rear admiral, Hina is only one military rank below Smoker and Garp, so she represents the Marines' military elite.
15 Jewelry Bonney
As with many One Piece characters, Jewelry Bonney's true strength is an enigma. Her reputation and unique abilities are certainly evidence of her strength, but she has yet to achieve a significant victory in battle. To this point in the series, the Supernova hasn't fought anyone that wasn't a generic fodder character.
While Bonney's lack of demonstrable feats holds her back, there is no denying the strength of her Devil Fruit powers. She's able to accelerate the aging process or turn back the clock on whatever living being she touches. It is a game-changing ability that could legitimately turn the tides of a battle if used in the right scenario.
14 Vinsmoke Reiju
Much like her younger brother Vinsmoke Sanji, Reiju (also known as “Poison Pink") is extremely powerful. Unlike most humans, she underwent genetic modifications that resulted in the development of superhuman abilities. She possesses inhuman strength and speed, which has been further enhanced thanks to the advanced military technology of Germa Kingdom.
Reiju also has superhuman durability thanks to an exoskeleton that protects her from regular gunfire and most weapons. However, her greatest strength is her ability to ingest and produce poison. This makes her a dire threat to most opponents, and in the right situation, it could completely negate an enemy's strongest weapon.
13 Monet
As a high-ranking member of the Donquixote Pirates, Monet is anything but weak. Formerly a regular human, she underwent a special procedure that swapped her human limbs with those of a bird. As a result, she became a harpy and acquired the ability to fly.
Furthermore, Monet is a Logia-type Devil Fruit user with the power to turn into and manipulate snow. On her own, she was able to take on both Robin and Nami, as well as almost kill Marine Captain Tashigi. While not as strong as the likes of Luffy or Zoro, she was still strong enough to briefly give the former some trouble.
12 Nami
In the early days of One Piece, Nami was almost certainly the weakest member of her crew. Today, thanks to her knowledge of meteorology, Usopp's inventions, and Big Mom's homie, Zeus, she can now manipulate the surrounding weather to unleash highly potent offensive attacks.
During the Raid on Onigashima, Nami squares off against numerous opponents, yet it is her stand against Ulti, the strongest female member of the Tobiroppo, that solidifies her as a New World Threat. With the help of a few attacks from Big Mom, Nami is eventually able to overpower Ulti, demonstrating that her new "glass cannon" status is well-earned.
11 Carrot
Despite her adorable appearance, Carrot is not to be underestimated. A natural-born fighter with superhuman strength and speed, she is a member of the Musketeer Squad and served under Inuarashi before eventually being named the new ruler of Mokomo Dukedom. Like all minks, she has the power to generate electrical currents using Electro.
Although Carrot is still young, she has already mastered the power of the Mink Tribe’s Sulong form. In this state, her physical strength and Electro-related abilities increase tremendously, allowing her to commit feats of incredible agility and strength. While using her Sulong Form, she was able to instantly dispatch dozens of pirates under Big Mom's command, even evading attacks from one of the Yonko's strongest sons, Charlotte Daifuku.
10 Belo Betty
Little is known about the abilities of Belo Betty, the commander of the Revolutionary Army's eastern branch. However, her 400 million berry bounty tells the story of an individual that is more than capable of holding their own in the fight against the World Government.
Belo Betty wields what is arguably the most unique Devil Fruit in the Revolutionary Army, the Pump-Pump Fruit. It allows her to raise the morale of her allies to the extent that it enhances their speed and strength, so even if Belo Betty's Armament and Observation Haki-related abilities can't defeat her opponent, her fellow revolutionaries surely can.
9 Black Maria
Black Maria is a member of the Beast Pirates' Tobiroppo and functioned as a chief overseer of many of their operations. She's shown to have a crafty mind for strategy, capable of easily capturing Sanji due to his chivalrous nature. Playing on people's weaknesses was the name of her game, and it's one she played well.
Black Maria's true strength stems from her Ancient Zoan-type Devil Fruit. The Spider-Spider Fruit: Model Rosamygale Grauvogeli allows her to take the form of an ancient species of spider and ensnare her opponents in an immobilizing layer of silk. While the female Tobiroppo member ultimately falls short in combat against Nico Robin, it's clear that she's still a massive threat to the New World.
8 Ulti
When the Tobiroppo are introduced during the Wano Country arc, both Ulti and her younger brother, Page One, quickly show off how strong they are. Ulti consistently takes on multiple opponents throughout the arc, staving off their attacks and proving her impossible durability.
Ulti's Ancient Zoan-type Devil Fruit, the Dragon-Dragon Fruit: Model Pachycephalosaurus, gives her incredible strength, and by using its hybrid forms, she almost overcomes the joint efforts of Usopp, Nami, and several other pirates. Were it not for the brief intervention of Big Mom, Nami's fight-ending attack would almost certainly not have incapacitated Ulti.
7 Tsuru
Gauging the strength of older One Piece characters like Vice Admiral Tsuru can be a bit of a crapshoot. The anime consistently shows that the eldest generation (a group consisting of legendary figures like Garp, Sengoku, and Silvers Rayleigh) still wields immense power, so one can only assume that Tsuru could go toe-to-toe with powerful pirates if she needed to.
Vice Admiral Tsuru's Devil Fruit, the Wash-Wash Fruit, is a bit of a mystery, but considering her position in the Marines, it's likely that it and her Haki-related abilities would make short work of most pirates. Even Donquixote Doflamingo exhibits caution in her presence, speaking to her unseen strength as a combatant.
6 Stussy
When Stussy first appears during the Whole Cake Island arc, she does not seem like much of a threat. However, this assumption quickly changes after it is revealed that she is a member of CP0. Later, Stussy's backstory takes another turn when it is revealed that she has been working as a double agent in CP0, instead owing her allegiance to the mysterious Dr. Vegapunk.
To join the ranks of CP0 takes serious strength, but to function as a double agent within the lethal group insinuates that Stussy is even stronger than many of her peers. She is confirmed to wield Observation and Armament Haki, withstood a blast of Conqueror's Haki from Big Mom, and knocked out Lucci and Kaku, so only time will tell what the limits of her abilities are.
5 Nico Robin
Nico Robin has one of the most tragic backstories in all of One Piece. For over 20 years, she was forced to constantly run from the World Government, unable to trust anyone around her. This hellish lifestyle helped mold her into a powerful fighter, and ever since joining the Straw Hats during the Alabasta arc, her overall power has grown exponentially.
Thanks to Robin's Flower-Flower Devil Fruit powers, she has slowly become one of the strongest members of the Straw Hat Pirates. In her fight against Black Maria during the Raid on Onigashima, Robin exhibits a new attack titled "Demonio Fleur" that allows her to transform into a giant, devil-like spider. This quickly makes short work of Black Maria, and it is likely a major factor in the Straw Hat Pirate's massive new bounty.
4 Catarina Devon
Catarina Devon, also known as the "Crescent Moon Hunter," is one of the 10 pirate captains serving under the Yonko Blackbeard. While not much is known about her, she is confirmed to be one of the most dangerous female pirates in the series. Furthermore, she survived a life-or-death battle royale at Impel Down between her and the other prisoners from its most dangerous section, Level 6.
This, in turn, guaranteed Devon a spot as an elite member of Blackbeard’s crew. She possesses the powers of a Mythical Zoan-type Devil Fruit which not only lets her transform into a nine-tailed fox but into other people as well. Although she was instantly petrified by Boa Hancock in their brief encounter on Amazon Lily, the Crescent Moon Hunter is sure to pose major problems for the Straw Hat Pirates in the near future.
3 Charlotte Smoothie
All of Big Mom’s three Sweet Commanders are extremely strong, so Charlotte Smoothie is undeniably a very capable pirate. She currently possesses one of the highest bounties among female characters, and as evidenced by her clashes during the Whole Cake Island arc, she can overwhelm opponents with only her superhuman strength and brilliant tactical mind.
What truly sets Charlotte Smoothie apart from her peers is her Wring-Wring Devil Fruit. Its powers allow Smoothie to wring out the liquids of anything or anyone with a single touch from her hands or sword. By absorbing these liquids, the Sweet Commander also increases her size and the potency of any attacks. Unfortunately, Charlotte Smoothie hasn't taken part in many significant battles, but with the inevitable war between pirates and the World Government quickly approaching, fans hope to catch a glimpse of her abilities sooner rather than later.
2 Boa Hancock
As the leader of the Kuja Pirates and the only female member of the Seven Warlords, the “Pirate Empress” Boa Hancock embodies the Kuja’s belief that “strength is beauty.” Her overwhelming beauty just so happens to greatly enhance the effectiveness of her Devil Fruit powers, which allow her to turn anyone that gazes at her with lust into stone.
Boa Hancock is capable of instantly defeating multiple members of the Blackbeard Pirates' Ten Titanic Captains by turning them to stone — a feat that the few characters in all of One Piece could replicate. Furthermore, she is the first female character in the series who was confirmed to be proficient in all three forms of Haki.
1 Charlotte Linlin
Charlotte Linlin, also known as Big Mom, is easily recognized as the strongest female pirate in One Piece. She knows virtually no equal. Even when she was five years old, Linlin was strong enough to easily throw a fully grown giant, and despite being in her late 60s, she is still powerful enough to easily withstand a blow from Gear Four Luffy.
In addition to Big Mom's skilled use of all three Haki forms, she also has the power to manipulate souls thanks to her Soul-Soul Devil Fruit. Its abilities allow her to harvest souls from others and use them to create living weapons known as homies, the strongest of which are Prometheus, a sun-like being that manipulates fire, and Napoleon, a living sword that is strong enough to survive a clash with Kaido. She's one of the few beings worthy of the title Yonko, and compared to other females in One Piece, none hold a candle to her otherworldly might.
