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.
10-FUJITORA
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. Every time he uses this ability, he draws his sword. He regularly uses this ability to precipitate giant meteorites from the sky or uses it to increase the force of gravity and immobilize an opponent on the ground.
Fujitora can also reverse gravity to create a circular barrier around him that repels all attacks or to levitate a battleship similar to Shiki’s Fuwa Fuwa no Mi. He can levitate a rock and use it as a mobile platform. He is also able to use gravity to attack horizontally, consequently hitting opponents and everything around him.
Fujitora has shown mastery over two types of Haki: Busoshoku Haki and Kenbunshoku Haki, which he uses to compensate for his blindness in battle.
9-KIZARU
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.
Kizaru was seen using an advanced level of Busoshoku Haki to negate Whitebeard’s attempt to destroy the execution platform, by creating, with his fellow admirals, a shield combination of their three Haki.
8-KUZAN
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.
Like Kizaru and Akainu, Kuzan is able to use an advanced level of Busoshoku Haki.
7-DRACULE MIHAWK
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. Mihawk has remained unharmed thus far throughout the entire series.
6-BLACKBEARD
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.
