QUEEN THE PLAGUE
Queen the Plague is an All-Star of the Beasts Pirates and one of Kaido’s three right-hand men, the Disasters. It has been implied that Queen is even stronger than the extremely powerful Jack.
Queen has the strength to stop a punch from Luffy with only one hand and then toss Luffy away, though these actions were done with his artificial arm. He also has tremendous durability as he was able to take a violent beating from the Yonko Big Mom and not suffer any visible bruises or injuries.
SENGOKU THE BUDDHA
Sengoku the Buddha was the fleet admiral of the Marines pre-timeskip, succeeding Kong and preceding Akainu.
Alongside Garp and Tsuru, Sengoku is one of the most powerful Marines of his generation. Even without his Devil Fruit powers, Sengoku has enormous strength, enough to effortlessly hold down an enraged Garp with only one hand.
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.
SHIKI THE LION
Alongside Roger and Whitebeard, Shiki is one of the most powerful pirates of his generation. He has tremendous physical strength supplemented with his supreme sword skills, allowing him to slay an army of Marines at Marineford, and it took the combined efforts of both Garp and Sengoku to subdue him with the conclusion of their fight leaving half of Marineford destroyed.
He has massive endurance as he could survive having parts of a steering wheel embedded deep into his head.
He also has immense tolerance to pain. After he amputated his own legs to break free of Sea Stone Shackles, Shiki was completely unfazed by the pain, even casually smoking a cigar. Without any medical treatment with profuse and heavy bleeding, he successfully broke out of the impenetrable security defenses of Impel Down single-handedly. Later in a crude form of emergency treatment, Shiki forcefully grafted his swords into the inner stumps of his amputated legs.
Even in old age, Shiki remained extremely powerful.
AKAINU
Akainu is the current fleet admiral of the Marines, succeeding the previous fleet admiral, Sengoku.
He possesses tremendous physical strength, as shown when he pinned Whitebeard’s giant bisento down to the ground with just one leg. Furthermore, he was the one who emerged victorious from the ten day duel between him and Aokiji for the position of the fleet admiral.
Akainu’s background is renowned, especially among the stronger figures in the New World, striking fear into the hearts of pirates and marines alike. After Van Augur identified Akainu aboard a marine ship for negotiations, Blackbeard immediately fled, knowing the consequences of battling against him, even though Blackbeard had gained the powers of the Gura Gura no Mi, and had strengthened his crew with several of Impel Down’s most powerful criminals.
BIG MOM
Charlotte Linlin, more widely known as 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. When she was just five years old, she was strong enough to kill a large bear instantly with a single smack, merely intending to scold the animal, as well as break several of a giant’s bones by trying to slap a mosquito on their back. When suffering from her cravings, she could destroy a village in Elbaf and defeat several armed giants without a single scratch, being described by Jorl as an “evil god in the form of a child”.
She was strong enough to not only break Jorl’s sword with her fist when he tried to attack her, but also grab the giant’s beard, flip him over her shoulder, and smash him into the ground with enough force to mortally wound him.
Mother Carmel believed she had the potential to become an Admiral or Fleet Admiral of the Marines.
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. In Wano, Kaido defeated Luffy with just one hit!
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.
WHITEBEARD
Edward Newgate, more commonly known as “Whitebeard”, was the captain of the Whitebeard Pirates and was known as “The Strongest Man in the World”. He was a member of the Yonko that ruled over the New World until his death during the Battle of Marineford.
Whitebeard was given the title of the “strongest man in the world” for his physical power, which is far superior to even a giant.
Despite being old and sick, his physical resistance and pain tolerance were tremendous: he was able to keep fighting despite the number of life-threatening injuries he sustained, which included part of his head being burned off. No matter how much damage he took throughout the battle, Whitebeard continued to press forward and fight, only stopping once almost all of the Blackbeard Pirates collectively shot and brutally stabbed him to death at point-blank range.
He sustained 267 sword wounds, 152 gunshot wounds, and 46 wounds from cannonballs, and got half of his head blasted off, resulting in 465 injuries in total. However, even after taking so much damage in his already weakened state, he died standing, an impressive feat when compared to other characters. Even Teach was shocked by Whitebeard’s tenacity.
GOL D. ROGER
Gol D. Roger was a legendary pirate who was known as the Pirate King, captain of the Roger Pirates, and owner of the legendary treasure known as “One Piece”. He was also the lover of Portgas D. Rouge and biological father of Portgas D. Ace.
Roger was hailed as the most powerful pirate of all time. His fighting power was nearly unstoppable. He single-handedly defeated the armies of several countries.
Only two people are known to have ever matched Roger in battle: Vice Admiral Monkey D. Garp and his rival Edward “Whitebeard” Newgate.
MONKEY D. GARP
Garp is one of the most powerful Marines seen in the series so far. As the “Hero of the Marines”, Garp is very well-respected for cornering the Pirate King multiple times.
He is able to throw iron canonballs like baseballs at speeds higher than if they were fired from an actual cannon, break through brick walls and cannon stands with his fists, and both carry and throw a gigantic ball and chain many times bigger than the Thousand Sunny. Garp also has a monstrous punching power at his disposal, with his epithet, “Garp the Fist”, vouching for the tremendous power of his punches. He claimed to have crushed eight mountains during his training to face Chinjao. Enhanced with Haki, Garp could even dent Chinjao’s Haki enhanced drill-shaped head, which was powerful enough to split the Jewel Ice Sheet.
Even in old age, Garp retained his strength. During the Battle of Marineford, he easily struck down Marco, a Mythical Zoan Devil Fruit User and one of the most powerful members of the Whitebeard Pirates, and in the anime, Garp knocked down Jesus Burgess, a master wrestler with titanic physical strength without effort. In fact, Sengoku had to personally restrain Garp before he attempted to kill Akainu out of fury.
