Most Yonko that have been seen in the story of One Piece so far have 3 extraordinary subordinates who are a cut above the rest. Just like the Yonko, they're close to each other in terms of power, but some are indeed stronger than the others.
Updated April 3, 2022, by Rei Penber: Yonko Commanders are some of the most impressive figures in the One Piece world, and over the years, several capable pirates have held this title. Although the original version of this list already included the strongest Yonko commanders in the show, there are quite a few others who, while not necessarily as strong, deserve to be mentioned as well. As such, this list has been updated to include further additions, honoring more of the strongest Yonko commanders In One Piece.
Charlotte Cracker is one of the three Sweet Commanders of the Big Mom Pirates. He was introduced in the Whole Cake Island arc with a bounty of 860 million berries. Cracker is extremely powerful and is capable of easily overpowering Luffy's Gear Fourth.
Although Cracker hates pain, he rarely allows anyone to get close to him thanks to his incredibly high defense offered by the power of the Bisu Bisu no Mi devil fruit. Cracker possesses incredible Armament Haki, as mentioned by Luffy.
Charlotte Smoothie is the second-strongest Sweet Commander in the story, second only to Katakuri. She possesses the power of the Shibo Shibo no Mi, which allows her to wring out all the moisture out of people.
She can also absorb moisture out of the air and use it to her advantage by manipulating it freely. Smoothie is incredibly powerful; however, she isn't all that smart, which is her biggest weakness and places her lower on the list.
Usopp's father, Yasopp, is an officer of the Red Hair Pirates and likely one of Shanks' three best men, as mentioned by the Marines in chapter 957 of the manga. Yasopp is a sniper who has been hailed to be the best by many.
Being an officer on Shanks' crew, it goes without saying that he possesses Haki as well. Yasopp's true strength hasn't been seen in the story so far, but fans might get a glimpse of what he's capable of soon.
Jack is one of the three right-hand men of Kaido, the strongest Yonko of them all, and an incredibly powerful pirate. He has a bounty of 1 billion berries on his head.
With the power of the Zou Zou no Mi, Model: Mammoth, Jack was able to fight Inuarashi and Nekomamushi for 5 days. The Devil Fruit gives him great strength and endurance; however, he's yet to win any fight that he's been in so far.
Ace was the Second Division Commander of the Whitebeard Pirates, and an extremely capable pirate. Although he's often assumed to be below the level of other Yonko Commanders, Ace was anything but that.
He had the power of the Logia type devil fruit Mera Mera no Mi along with possibly all the Haki types (Observation being unconfirmed). On Fishman Island, Ace was able to fight Jinbe for five days straight to a draw, and moments later, fight Whitebeard while Jinbe was still down. According to Shanks, Ace was worthy of being the Second Division Commander and Blackbeard praised his strength as incredible.
Roux is a member of the Red Hair Pirates and an incredibly strong pirate. Although very little is known about his ability, fans do know that he's extremely powerful judging from his stature.
According to the Navy, Lucky Roux is a very capable pirate with a very high bounty on his head. He hasn't been seen in combat yet. However, the series creator has suggested that the story will focus more on one of the strongest Yonko, Shanks, after the Wano Country arc, which implies that fans will see more of him soon.
Queen is one of Kaido's three All-Stars and second only to the Yonko and King in the crew. He possesses the power of the Ryu Ryu no Mi, Model: Brachiosaurus which is an Ancient Zoan power that makes him extremely strong and resilient.
Queen is also a user of Haki and has kept up with the likes of Marco in battle. His entire body is enhanced with cybernetics, giving him great versatility in battle. Queen remains to be one of the strongest Yonko Commander with his best yet to be seen.
Vista is one of the strongest division commanders of the Whitebeard Pirates. Known as the best swordsman of the pirate crew, Vista is famous throughout the world and even the strongest swordsman, Dracule Mihawk, respects him.
During the Paramount War, Vista fought Mihawk for quite a while and was strong enough to tie the fight. He's a decent user of Haki, and when combined with his swordplay, it makes him extremely capable.
Diamond Jozu is the former Third Division Commander of the Whitebeard Pirates. He was responsible for leading the combatant unit of the crew, making him one of the core members of the group.
Jozu possesses the powers of the Paramecia-type Kira Kira no Mi which allow him to turn himself into a diamond, increasing both his power and durability. He was able to stop Mihawk's slash quite easily in Marineford and even fought Aokiji on even footing until he got distracted by Whitebeard's worsening health.
King is a member of the Lunarian race who once lived on top of the Red Line. His clan's ability allows him to manipulate flames and produce them quite easily in combat.
On top of every ability that he has from his clan, King is also a user of the Ryu Ryu no Mi, Model: Pteranodon which allows him to become the said creature and its hybrid at will. He's a capable user of Haki and could fight Marco to some extent, just like Queen.
Formerly an Impel Down Jailer, Shiryu is now the leader of the second ship of the Blackbeard Pirates. He's also Teach's strongest man, meaning he's among the mightiest Yonko Commanders as well. Shiryu wields a sword called Raiu, which appears to be bloodthirsty.
At the same time, Teach also has the power of the Suke Suke no Mi devil fruit, making him an invisible man. All his skills put together make him a terrific fighter in the One Piece world.
Charlotte Katakuri is the strongest of the Sweet Three Generals of the Big Mom Pirates and has a bounty of 1,057,000,000 berries on his head. Until recently, Katakuri had never lost even a single battle in his life.
He is a user of the Mochi Mochi no Mi, which is a Special Paramecia and allows him to create, control, and turn into mochi at will. He's also a very capable user of all the three Haki types, making him an extremely skilled fighter. Katakuri's biggest power is the ability to see the future using his Observation Haki.
Ben Beckman is an officer of the Red Hair Pirates and their First Mate. He's an incredibly powerful figure who is also known as the smartest man from East Blue.
According to Brannew, Beckman has a high bounty on his head, however, the exact figure remains unknown so far. In the future, Ben Beckman's power will be focused on a lot more and the fans will get a clear idea of how strong he truly is.
Marco is the former First Division Commander of the Whitebeard Pirates and their acting captain after Whitebeard's death. He is an incredibly powerful figure who possesses a bounty of 1,374,000,000 berries on his head.
Marco uses the Tori Tori no Mi, Model: Phoenix, which allows him to turn into a Phoenix and access the blue flames of resurrection. He was shown to be strong enough to hold back even Akainu in Marineford and on Onigashima, he fought and overwhelmed both King and Queen at once.
