As time moves forward, Luffy evolves into an exceptionally formidable pirate, ranking amongst the mightiest warriors in this vibrant world. However, his astonishing growth comes through battles against numerous foes, many of whom vary in skill level. Some adversaries, nonetheless, are undeniably recognized as the strongest within the narrative.
Updated as of October 31, 2024, by Rei Penber: Fans of One Piece have encountered some of the most fascinating villains throughout the series. Oda excels in crafting captivating characters, regardless of whether they align as heroes or villains. Particularly with the recent conclusion of the Wano arc, where the formidable Kaido was finally defeated, the storyline has seen significant evolutions, leading to new introductions of powerful and fearsome villains in the ongoing saga. While this list previously covered a wide spectrum of major villains in One Piece, it has now been enhanced to reflect those emerging from the latest saga.
28 Captain Kuro
Major Arc: Syrup Village
Captain Kuro stands out as one of the primary villains in the East Blue Saga of One Piece. As the central antagonist of the Syrup Village arc, he posed a significant challenge to Luffy and the Straw Hat Pirates before ultimately being vanquished by them.
While Kuro may not have been the most formidable opponent within the East Blue Saga, his skills included the elusive Pussy Foot Maneuver and razor-sharp claws capable of slicing foes. Nevertheless, Luffy adapted swiftly, leading to Kuro’s defeat.
27 Don War
Major Arc: Baratie
Don Krieg was one of the mightiest adversaries faced by Luffy in the East Blue arc. He boldly claimed to be the strongest being on the ocean, proving to be a considerable challenge for Luffy during their encounter. Equipped with an arsenal of powerful weaponry, he launched a series of attacks in a failed attempt to dominate Luffy.
Similar to many of the early antagonists, he fell short compared to those who followed in the storyline. Nonetheless, Krieg’s willingness to employ unscrupulous tactics in battle provided him with a notable advantage, staying true to his pirate nature.
26 Arlong
Major Arc: Arlong Park
Arlong emerged as the key antagonist in the Arlong Park arc of One Piece. As a Fishman, born much stronger than a regular human, Arlong displayed the ability to decimate entire towns effortlessly, particularly seen in his tyrannical reign over Cocoyashi Village.
Although Luffy confronted Arlong head-on, Arlong’s mastery of Fishman Karate was relatively lacking. Despite this, he demonstrated considerable strength, easily overpowering other notable pirates like Zoro and Sanji without much difficulty.
25 Orochi
Major Arc: Wano
In the Wano Country arc, Orochi steps into the spotlight as a significant villain. Initially mentioned during the Zou arc, he is revealed in Wano with ambitions aimed at the country’s destruction.
While his character is undoubtedly one of the most despicable in One Piece, Orochi’s power is somewhat limited. His Mythical Zoan-type Hebi Hebi no Mi, Model: Yamata no Orochi, grants him the ability to morph into a multi-headed serpent. Although he possesses eight lives, his combat abilities remain relatively weak.
24 Buggy
Major Arc: Orange Town
Buggy is yet another notable villain introduced in the East Blue Saga. As the principal antagonist during the Orange Town arc, he was also the first Devil Fruit user encountered by fans besides Luffy. His unique abilities contributed to his role as an interesting villain and allowed him to appear across multiple arcs since then.
While not among the strongest pirates, Buggy’s fame and notoriety grew immensely, culminating in his current position amongst the Four Emperors of the Sea, indicating he’s likely become significantly more powerful over time.
23 Sea Gecko
Major Arc: Thriller Bark
Serving as the main antagonist of the Thriller Bark arc, Gecko Moria was one of the Shichibukai, gaining recognition for his formidable power. His abilities warranted a significant bounty of 320 million berries, which remained frozen for a time. Moria wields the Kage Kage no Mi, a Paramecia-type Devil Fruit that permits him to manipulate shadows with finesse.
Throughout the Thriller Bark arc, Moria demonstrated enough strength to dominate Oars, compelling Luffy to employ both Gear Second and Gear Third simultaneously to bring him down.
22 Rod
Major Arc: Punk Hazard
Vergo, a prominent member of the Donquixote Pirates, stood as one of Doflamingo’s most trusted allies. His strength was remarkable, and despite lacking any Devil Fruit abilities, his proficiency in Haki was exceptionally high.
Vergo showcased his combat abilities in a fight against Smoker and, notably, engaged Law only when Law was without his own heart. Although Vergo proved to be strong, he ultimately fell to Trafalgar Law in a decisive blow.
21 Hody Jones
Major Arc: Fishman Island
Hody Jones served as the primary antagonist in the Fishman Island arc. A character shaped by accumulated hatred, Oda developed Hody into a complex villain, though his actual strength left much to be desired.
As a Fishman, he displayed subpar abilities and resorted to steroids to amplify his power, yet even then, he could not compete with Luffy in battle. Eventually, Hody was decisively defeated by the Straw Hat captain, but he undoubtedly left his mark on the overarching narrative.
20 Caesar Clown
Major Arc: Punk Hazard
Caesar Clown was pivotal as the main antagonist in the Punk Hazard arc, the first island where Luffy and his crew ventured in the New World. It was here that Caesar’s unethical experiments on children, aimed at gigantification, were unveiled. Moreover, he was responsible for creating SAD and Smile Devil Fruits for Doflamingo, which in turn were supplied to Kaido, a recognized Yonko.
Although Caesar is relatively small in the larger context of the One Piece universe, he played a significant role during the arc, directly challenging Luffy who ultimately defeated him, showcasing Luffy’s growth and resilience in the New World.
19 Enel
Major Arc: Skypia
Enel emerged as the main antagonist in the Skypiea arc, wielding the devastating power of the Logia-type Goro Goro no Mi. His overwhelming abilities enabled him to obliterate Birka and he intended to unleash similar destruction upon Skypiea shortly afterward.
With considerable might, Enel effortlessly dispatched several powerful fighters, including Zoro, Wyper, and Robin. It took the full extent of Luffy’s abilities for him to overcome Enel in combat, underscoring the latter’s formidable strength.
18 Rob Lucci
Major Arc: Enies Lobby
The apex member of CP9, Rob Lucci served as the primary antagonist in the Enies Lobby arc. He confronted Luffy during this pivotal storyline, boasting a Doriki rating surpassing 4000, making him one of Luffy’s strongest opponents at that time.
His masterful use of Rokushiki techniques, including the formidable Rokuogan, attests to his combat prowess. Even with Luffy utilizing Gear Second and Gear Third, he found defeating Lucci a challenging feat, and without Usopp’s timely assistance, Luffy may well have faced defeat.
17 Crocodile
Major Arc: Alabasta
Much like Moria, Crocodile was another notable member of the Shichibukai and served as the main antagonist of the Arabasta arc. Throughout their encounters, he managed to defeat Luffy on two occasions. To ultimately triumph over Crocodile, Luffy was required to depend on fortuitous circumstances while pushing beyond his limits. The powers offered by the Suna Suna no Mi made Crocodile a formidable adversary.
As a Logia-type user, he became one of the few true powerhouses, and following his escape from Impel Down, Crocodile appeared to grow even stronger than he was during the Arabasta arc.
16 Magellan
Major Arc: Impel Down
As the main antagonist of One Piece’s Impel Down arc, Magellan held a powerful position as the prison warden of the world’s most notorious prison. He nearly claimed Luffy’s life during their confrontation, showcasing his strength and prowess.

His prowess was so vast that he even managed to eliminate the entire Blackbeard Pirates with ease during the Impel Down arc, emphasizing his exceptional combat abilities. Despite the combined efforts of numerous prisoners to confront him, they found themselves outmatched and ultimately fled in search of escape from Impel Down.
15 Doflamingo
Major Arc: Dressrosa
Doflamingo, hailed as the King of Dressrosa, served as the central villain during the arc based on the island. After the timeskip, Doflamingo was the initial pirate to put Luffy to a severe test. Bestowed with the powers of the Ito Ito no Mi, he could manipulate strings at will. His mastery of all three Haki types rendered him a unique and formidable pirate in the series.
To secure victory against him, Luffy had to activate Gear Fourth on two separate occasions, confirming Doflamingo’s status as a powerful challenger.
14 Bartholomew Kuma
Major Arc: Thriller Bark
Bartholomew Kuma emerged as an antagonist in the Thriller Bark arc, where, despite Gecko Moria being the main villain, Kuma’s presence was marked by a level of threat that eclipsed Moria. He engaged in combat with Roronoa Zoro, proving capable of defeating not just him, but the entire Straw Hat Pirates and others present on Thriller Bark.
Kuma would have executed Luffy had it not been for the intervention of his crew, particularly Zoro. His later actions at Sabaody Archipelago, where he separated the Straw Hat crew, exhibited his dual role as both antagonist and savior, performed masterfully within the storyline.
13 Greenbull
Major Arc: Wano
As one of the Marines’ Admirals, Green Bull is undoubtedly ranked among the elite characters in One Piece. With a staggering bounty of 3 billion berries on his head, he exemplifies formidable strength.
He possesses the Mori Mori no Mi, a powerful Logia-type Devil Fruit that grants him the ability to transform into a forest and control all associated vegetation. His skills also extend to powerful Haki, and he demonstrates proficiency as a swordsman. Green Bull ranks as one of the top-tier figures in One Piece and while he didn’t serve as a principal antagonist in Wano, he’s sure to play a crucial role in the Final Saga, warranting his high ranking.

Major Arc: Egghead Island
Kizaru was introduced during the Sabaody Archipelago arc, showcasing powers derived from the Pika Pika no Mi. With this powerful Logia Devil Fruit, he can manipulate light and transform into it at will, demonstrating overwhelming power against the Supernova on Sabaody.

11. Akainu
Major Arc: Marineford
Akainu stands as one of the most significant villains in the One Piece cosmos, confronting Luffy for the first time during the Marineford arc. Utilizing the Magu Magu no Mi, he attempted to eliminate Luffy on two separate occasions but ultimately failed. Following these events, Akainu ascended to the role of Fleet Admiral of the Marines, enhancing his strength considerably.
He stands as one of the few individuals capable of clashing with the Yonko, which reinforces his status as one of the most formidable villains in One Piece.
10 Blackbeard
Major Arc: Marineford
A prominent Yonko, Blackbeard is a remarkably powerful pirate who commands two Devil Fruits: the Gura Gura no Mi and the Yami Yami no Mi. Throughout the years, he has significantly strengthened his powers and consolidates his influence across the One Piece world.
Responsible for taking Ace’s life and defeating Whitebeard, Blackbeard is among the few able to rival Luffy’s ambition to become the Pirate King, prepared to employ any tactic necessary to seize the One Piece for himself.
9 Big Mom
Major Arc: Whole Cake Island
