Characters included in the list have to be active as either Pirates, Marines, Warlords or Revolutionaries. For example, Sengoku, Monkey D. Garp and Silvers Rayleigh have retired so they are not included.
Fujitora is a Marine admiral. In terms of combat strength, he is considered to be one of the strongest fighters within the entire World Government structure.
Fujitora ate the Zushi Zushi no Mi, a Paramecia-type Devil Fruit that allows him to manipulate gravity around a chosen location at will by sending gravitational forces. Fujitora can manipulate gravitational forces by channeling his Devil Fruit ability through his sword. He can send the gravitational forces by swinging or just simply moving his sword.
Fujitora has also shown mastery over two types of Haki: Busoshoku Haki and Kenbunshoku Haki, which he uses to compensate for his blindness in battle.
Fitting his title of admiral, Kizaru is one of the most powerful fighters within the World Government and the Marines.
The greatest aspect of Kizaru’s physical abilities is his immense speed and extraordinary reflexes, which is further enhanced by the light based powers of his devil fruit. Kizaru, in fact, possesses the power of the Pika Pika no Mi, a Logia-type Devil Fruit that grants him the powers of the element of light.
He is capable of moving and attacking at the speed of light, and all of his attacks are based on the element of light, such as firing energy blasts from his fingertips or feet with extreme accuracy and precision. His power is very destructive, causing huge explosions and can easily destroy buildings. He also has the ability to reflect himself, essentially moving from one location to the next at the speed of light. Due to this fruit’s power, Kizaru is possibly the fastest man in the world.
Mihawk is the current holder of the title, “Greatest Swordsman in the World”.
Part of Mihawk’s reputation as the most powerful master swordsman in the world is also due to his tremendous superhuman physical power and fortitude which supplements his mastery of swordsmanship. He possesses an immense amount of skill in battle and has exceptional eyesight.
The fact that Mihawk used to be a rival of one of the Yonko implies that Mihawk might be one of the strongest characters in the series. Infact he has been known to have frequently fought with Shanks when they were younger. Their battles were said to shake the whole of the Grand Line and Mihawk often sought Shanks out for duels. However, Mihawk lost interest in him after Shanks lost his left arm.
Kuzan is a former Marine admiral. He was nominated by Sengoku for the position of fleet admiral but after losing the position to Sakazuki, he resigned from the Marines and affiliated himself with the Blackbeard Pirates.
Kuzan has the powers of the Hie Hie no Mi, a Logia Devil Fruit that allows him to control, create, and become ice. In battle, he uses his ice powers to disable and immobilize enemies, freezing their bodies solid just by touching them, and threatening to shatter their fragile forms. This fruit is so powerful that his usage of it during his ten day battle with Akainu permanently changed the weather on one side of Punk Hazard, turning that side into a frozen wasteland.
Kuzan was considered to be a massive asset to the Marines, and his departure left a negative impact to their military strength. This was confirmed by the Gorosei calling him an ‘enormous power’ while discussing his affiliation with the Blackbeard Pirates, to the point of being visibly distraught while doing so.
Blackbeard is the admiral of the Blackbeard Pirates and the newest member of the Yonko. He has an immense amount of superhuman endurance and tremendous physical strength even for his comparable size.
Blackbeard has become the first and, so far, only user to wield the powers of two Devil Fruits at the same time. With the power of darkness (Yami Yami no Mi), which “reduces anything to nothingness”, and the power of quakes (Gura Gura no Mi), which “brings destruction to everything”, Blackbeard claims himself to be truly invincible and the strongest pirate in the world.
The most prominent feats of Teach’s power was defeating three commanders of the Whitebeard Pirates: Portgas D. Ace, Thatch, and later during the Payback War, Marco, the new Captain of the Whitebeard Pirates.
Big Mom, is the captain of the Big Mom Pirates and the only female member of the Yonko.
Big Mom has immense superhuman physical strength and tremendous superhuman durability due to her extremely tough skin. Mother Carmel believed she had the potential to become an Admiral or Fleet Admiral of the Marines.
Big Mom can utilize and has shown mastery over two types of Haki: armament Haki and Conqueror’s Haki.
Big Mom has acquired the powers of the Soru Soru no Mi a powerful Paramecia-type Devil Fruit that allows her to manifest the soul of whomever she touches into an ethereal substance. She can put harvested souls into non-living things in order to give them life or into animals in order to give them human abilities. Those creatures are named Homies. She can also use fragments of her own soul to create Special Homies that are far more powerful than ones created with other people’s souls: Zeus, a thundercloud she summons with her left hand; Prometheus, a sun she summons with her right hand; and Napoleon, a bicorne she wears on her head.
Kaido of the Beasts is the captain of the Beasts Pirates and one of the Yonko.
As one of the Yonko, Kaido is among the strongest pirates alive, renowned as the “Strongest Creature in the World”. He attempted to take Whitebeard’s life, something few would dare, and subsequently clashed with Shanks. When Gekko Moriah was in his prime, Kaido fought him and emerged victorious, having killed his entire crew. In Wano, Kaido defeated Luffy with just one hit!
Kaido appears to have eaten a Zoan-type Devil Fruit that allows him to turn into a serpentine dragon.
Kaido has tremendous physical strength, but the greatest sign of his strength is his apparent inability to die due to his tremendous toughness and durability. He has been caught and tortured 18 times, and people as powerful as the Marines and other Yonko have attempted to execute him 40 times only to fail as Kaido survived every single attempt because every single execution weapon broke when being used on him. Most notably, Kaido has jumped from 10,000 meters from the sky onto the ground, creating a massive shockwave strong enough to sink a large ship nearby, and emerged only with a headache; it has even become a hobby for him to attempt suicide, only for it to fail.
Akainu is the current fleet admiral of the Marines.
Akainu has shown to possess tremendous strength and an immense amount of superhuman durability.
He possesses the Magu Magu no Mi, a Logia-class Devil Fruit which grants him the ability to transform his body into magma and manipulate it at will, as well as produce near-limitless amounts of it. His ability is naturally of a higher order than Ace’s pyrokinetic abilities, as the higher heat and smothering abilities of his magma allowed him to successfully harm Ace despite Ace’s Logia-defense, and ultimately kill Ace due to this superiority. According to Oda “with his level of controlling and the ability to freely manipulate the Lava, Akainu has the most powerful attack among devil fruits”.
During the decisive ten day battle on Punk Hazard for the position of fleet admiral, Akainu showed the furious power of his Devil Fruit as he changed the weather of one side of Punk Hazard and left it in a blaze.
Eiichiro Oda stated that if Akainu were to become the protagonist, he is so strong that he could end the One Piece series within a year.
“Red-Haired” Shanks is the captain of the Red Hair Pirates and a member of the Yonko.
Shanks’ full fighting potential hasn’t been explored yet but there is a lot of hints that indicates Shanks is an extremely powerful individual. For starters, he was able to scare off a massive Sea King just by staring at it (until we figured out he used Conquerors Haki: the strongest form of Haki). He also clashed evenly with Whitebeard, a fellow Emperor and even fought another, Kaido, and arrived at Marineford without a scratch on him. Additionally, he managed to ward off Ankinu where the savage admiral seemed a bit shocked at his presence and stopped going after Luffy after he came. Most of all, Blackbeard, who had the powers of the destructive Gura Gura no Mi Fruit and the evil Yami Yami no Mi Fruit chose not to fight Shanks saying “he is not strong enough to fight him yet”. That right there makes Shanks a force to be reckoned with and definitely one of the strongest guys in the series.
1-MONKEY D. DRAGON
Monkey D. Dragon is the infamous leader of the Revolutionary Army who has been attempting to overthrow the World Government. He is the World Government’s greatest enemy and is the most dangerous and most wanted man in the world. Dragon is already a powerful threat in his own right, as well as having powerful subordinates such as Sabo, Ivankov, Bartholomew Kuma, and Inazuma who are in comparison, lower in rank. This only speaks volumes of Dragon’s true power.
When he was mentioned at the Summit War everyone froze, just at the thought of Dragon. Everyone is scared of him. He is at least Yonko level. Maybe the strongest character of the series.
