Updated June 17, 2025, by Suzail Ahmad:Eiichiro Oda is one of the greatest mangaka of all time. He has achieved fame and success because of his hard work. The One Piece manga is proof of Oda’s genius. He has created a manga that is nearly perfect in all regards.
Unlike many other authors, Eiichiro Oda uses villains in more ways than one. He doesn’t just put them as an obstacle in Luffy’s path, but as a means to improve him mentally. With that in mind, here arethe best villains in One Piece.
39Don Krieg
Captain Of The Krieg Pirates
Don Krieg appeared in the East Blue Saga. Don Kreig was a cruel individual who had the ego the size of Zunesha. He called himself the strongest person on the sea, which was a massive exaggeration. That said, he did give Luffy an excellent fight, and the latter had to dig deep to beat him.
Don Krieg had no redeeming qualities. He was a sadistic person who didn’t mind killing his crew members if they went against his wishes. If villains were measured by just how evil they were, then Don Krieg would certainly be in the top ten.
38Bluejam
Leader Of The Bluejam Pirates
Bluejam might not have featured heavily in One Piece, but it is hard to overlook his impact on the story. Bluejam led his own pirate crew, and all of his underlings were terrified of him. After all, Bluejam despised failure, and he would kill them if they were unsuccessful in their attempt.
Bluejam’s main goal was to become a noble and live a life of leisure; for that, he was willing to go to any lengths. When he was finally given the opportunity, he was ready to sacrifice all the people in the Gray Terminal. Given his actions, Bluejam is one of the better One Piece villains.
37Vergo
Doflamingo’s Agent & A Vice Admiral
Vergo was introduced in the Punk Hazard arc as a Navy Vice Admiral. But at the time, fans had no idea that he was an undercover agent working for Doflamingo. Vergo had a dominant presence, and his subordinates respected him a lot. They religiously believed that Vergo fought for justice and that he could do no wrong.
Vergo exploited their trust and ruthlessly killed them one after the other. He was also a powerful fighter who could use Armament and Observation Haki. He was particularly proficient at using Armament Haki as he could cover his entire body with it.
36Sentomaru
Sentomaru is the head of the Marines' science department. In addition to being associated with the Marines, he is also Vegapunk’s bodyguard. Sentomaru’s first-ever appearance in One Piece came in Saboady. He was with the Pacifista, the advanced weapons created by Dr. Vegapunk.
In the arc, Sentomaru had a brief tussle with the Straw Hat Pirates. He was dominant in the fight, and Luffy couldn’t get even close to him. Sentomaru has respectable control over Armament Haki, and he can emit it over short distances. Sentomaru was quite proud of his defense, and he considered it impenetrable. While Sentomaru was certainly powerful, he did not make as big of an impact as some of the other villains, and that was mainly due to the debut of Admiral Kizaru.
35Bellamy
A Big Fan Of Doflamingo
At the time of his introduction, Bellamy came off as a dangerous pirate. He taunted and mocked every person with grand dreams, and if they tried to talk back, he would beat them up. Bellamy even laid hands on Luffy, but the latter did not fight back. This inflated Bellamy’s ego even further, but it all came crashing later when Luffy beat him with a single punch.
Bellamy appeared again in the Dressrosa arc, stronger than before. He had learned to use Armament Haki, and he combined it with his Devil Fruit. Unfortunately for him, he was way behind Luffy and the others, so he couldn’t do much.
34Foxy
Leader Of The Foxy Pirates
Foxy was the main antagonist of the Long Ring Long Island. Unlike most villains, Foxy does not have the hallmarks of being a cruel individual, but that does not mean that he is a generous soul. Foxy is an expert at swindling others, and he uses this particular skill in fights.
Foxy is a fan of Davy Black fights, and he uses the competition to steal individuals from other pirate crews. Despite not having any overpowered abilities, Foxy was able to leave his mark on the audience.
33Charlos
A Sordid Celestial Dragon
Charlos is a Celestial Dragon who made his debut in the Sabaody Archipelago arc. As a Celestial Dragon, Charlos' life holds more value than that of a regular person. He is free to do whatever he wants, and he doesn’t even have to suffer the brunt of his actions. Charlos came to Sabaody to participate in an auction in which people from all kinds of races were being sold. Charlos' status as a Celestial Dragon meant that he could spend exorbitant amounts of money on whatever he pleased.
At the auction, Charlos tried purchasing Camie. If that wasn’t bad enough, he shot Hatchi for being a Fish-Man. Later in the Levely arc, Charlos does the unthinkable by trying to capture Shirahoshi, a princess of the Ryugu Kingdom. Clearly, Charlos does not have an ounce of humanity in him, but he does the job of a villain superbly.
32Kuro
Captain Of The Black Cat Pirates
Kuro is one of the many villains that the Straw Hats encountered in the East Blue Saga. He was living undercover in Syrup Village as a butler for Kaya. Kuro had concocted a plan to take over Kaya’s wealth and then live happily.
After his plans were exposed, he decided to attack the village with his crew. Kuro’s speed, along with his long claws, made it extremely difficult to fight him. A person with slow reflexes would never stand a chance against him. His best quality was his intelligence. Kuro had a very high IQ, and he could outsmart most people in the story. After his defeat, Kuro disappears, but there are some fans who think that he might make an appearance in the future.
31Jack
Third Strongest All-Star
Jack was the first All-Star to be introduced in the story. He ate the Zou Zou no Mi, Model: Mammoth, an Ancient Zoan-type Devil Fruit that allowed him to transform into a Mammoth. His Devil Fruit significantly enhanced his physical attributes, giving him an edge in battle.
Jack was a ruthless man who was willing to go to great lengths for the sake of a mission. For instance, he nearly destroyed the entire Mokomo Dukedom when they refused to hand over Raizo. Jack used his own power first, but when it proved to be ineffective, he used the poisonous gas developed by Caesar.
30Orochi
Shogun Of Wano
Orochi was one of the main villains of the Wano Country arc. Many years prior to the current timeline, Orochi was nothing more than a weakling who had no authority whatsoever. But he carefully planned his ascension to power. Orochi ousted Oden with the support of Kaido.
Orochi was extremely cunning, and he made sure that nobody would rebel against him. He executed people for speaking against him, which made them stay in line out of fear of losing their lives. While Orochi did have a Devil Fruit, he did not have great control over it. He could only intimidate and kill people who were weaker than him. If he had trained more, Orochi could have easily become one of thestrongest characters in the series.
