#10 – SABO
Sabo is the Revolutionary Army’s chief of staff, recognized as the “No. 2” of the entire organization, ranking directly under Monkey D. Dragon himself.
After joining the Revolutionary Army, Sabo was personally trained by Monkey D. Dragon and attained tremendous physical prowess by adulthood.
Sabo ate the Mera Mera no Mi, which originally belonged to his brother Ace before his death. With it, Sabo is able to become the element of fire and control the flames from his body at will.
He can utilize and has shown mastery over two types of Haki: Armament Haki and Observation Haki.
Sabo could fight on equal level with Fujitora, a Marine Admiral and an immensely powerful swordsman, and emerged with only a few bruises. Later, Sabo single-handedly defeat Burgess, an immensely powerful wrestler who is one of the most powerful members of the Blackbeard Pirates with only minimal effort.
#9 – KUZAN
Kuzan, better known by his epithet Aokiji, is a former Marine admiral. After the time-skip, he became affiliated 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. He can create enough ice to cover a giant, a Sea King or several square miles of ocean within mere moments.
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.
#8 – SILVERS RAYLEIGH
Silvers Rayleigh, also known as the “Dark King”, is the former first mate of the Roger Pirates, known as the “Right Hand of the Pirate King.
Rayleigh is extremely powerful, easily one of the strongest characters introduced.
He could intercept Kizaru’s attack when the Admiral was about to kill Roronoa Zoro without Kizaru noticing, and also managed to keep up with his light enhanced speed.
Rayleigh is one of very few people who can use all 3 types of Haki: Armament Haki, Observation Haki and Conqueror’s Haki.
Rayleigh infact has shown to possess great mastery of Haki, and made use of all three types while teaching Luffy about them, and training him in the basics.
#7 – EDWARD WEEVIL
Edward Weevil, or “Whitebeard Jr.”, is the self-proclaimed son of “Whitebeard” Edward Newgate and one of the Shichibukai.
His powers have been praised by Kizaru who compared his abilities to that of a younger Whitebeard, his alleged father. He was able to single-handedly defeat 16 pirate crews affiliated with Whitebeard, including the A.O Pirates, without taking a single injury.
#6 – 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.
#5 – BIG MOM
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 create incarnations of her own soul.
#4 – 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.
#3 – KAIDO
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.
The Gorosei mentioned Kaido as one of the few people able to stop Blackbeard.
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.
#2 – SHANKS
“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.
