Summary
Akainu is the Fleet Admiral of the Marines, a position that he gained after winning a gruesome duel against his fellow Admiral, Aokiji. The fight between the two was so intense that it evenly split the climate of Punk Hazard. As the new Fleet Admiral, Akainu has the opportunity to impose draconian laws on the Marines and change the world ofOne Piece.
Akainu hasn’t shown his new powers, but it would be preposterous to assume that he must have become more powerful now. Given his status and his feats in the Summit War, there are not manyOne Piececharacters who can stand their ground in a fight against the Fleet Admiral.
Updated on June 30, 2025, by Suzail Ahmad:Since the time-skip, Akainu’s screen time has gone down significantly, but there is no reason to be worried. Akainu is the Fleet Admiral, which means he is one of the final villains that Luffy and his group will fight, so it makes sense to keep him away from the spotlight. As the story progresses, fans will get to seeAkainuin action regularly. For now, the fiery leader of the Marines has too much on his plate, so he can’t leave the headquarters to catch some pirates.Akainupossesses an incredible amount of power, and there are not many characters who can successfully defend themselves from his attacks. However, the Final Saga of One Piece has revealed some individuals who canbeat Akainuin a fight.
14Sengoku
Former Fleet Admiral Of The Marines
Sengoku was in charge of the Marines for a long period of time. Under his guidance, the Marines achieved many great things. Sengoku’s leadership was put on display in the Summit War, where he successfully defeated the Whitebeard Pirates.
He is not callous like Akainu, but Sengoku is very close to him in terms of strength. The former Fleet Admiral possesses the Hito Hito no Mi, Model: Daibutsu, a Mythical Zoan-type Devil Fruit that allows him to transform into the Golden Buddha. In his transformed state, Sengoku can emit shockwaves from his hand that are strong enough to nullify attacks from the Gura Gura no Mi. Sengoku is an experienced fighter, so he would have no problem facing someone like Akainu in battle.
13Silvers Rayleigh
Master Of All Three Types Of Haki
Silvers Rayleigh was the right-hand man of Gol D. Roger. Roger and Rayleigh were very close; in fact, Rayleigh was the first person to join the would-be Pirate King on his adventure. Just like his captain, Rayleigh is considered one of the most powerful pirates of his era.
Rayleigh does not possess any Devil Fruit ability; instead, he relies completely on his Haki. He has control over all three types of Haki, and he can use the advanced version of at least two of them. Even in his old age, Rayleigh managed to stop and injure Kizaru, one of the three Navy Admirals. Furthermore, his presence was enough to scare Blackbeard and force him to leave Boa Hancock alone. The fight between Rayleigh and Akainu would be close, but the Dark King is likely to emerge as the winner.
12Big Mom
As Strong As Kaido
Big Mom was a Yonko who ruled Totto Land along with her children. She was an extremely ruthless person who would kill her own children when enraged. In terms of strength, Big Mom was equal to Kaido, and this is supported by the fact that they fought for several days without there being a winner.
Big Mom possessed the Soru Soru no Mi, a Paramecia-type Devil Fruit that allowed her to steal the souls of other people. She used its power to create powerful homies who would serve her loyally. If Big Mom ever fought Akainu, the Yonko would easily defeat the Marine.
11Shiki
Roger’s Rival
Shiki used to be a member of the Rocks Pirates before starting his own crew. He was involved in the God Valley Incident, where he competed against some of the biggest names in theOne Pieceworld.
Shiki ate the Fuwa Fuwa no Mi, which enabled him to levitate himself and inanimate objects. While the power may not be flashy, it was indubitably strong. The combination of his Devil Fruit and physical abilities was enough to fight Garp and Sengoku at the same time. While fighting, Shiki destroyed a good chunk of Marineford and injured Garp severely. Given his feats, it is obvious that Shiki can defeat Akainu.
10St. Figarland Garling
Extraordinary Swordsman
St. Figarland Garling is the leader of the God Knights, who are responsible for maintaining law and order in Marijoa. He was involved in the God Valley Incident, in which the Rocks Pirates were defeated.
St. Figarland Garling wields a sword, which implies he is a talented swordsman. In addition to his physical strength, he also has a great deal of authority. St. Figarland Garling was able to execute Donquixote Myosgard because of his actions against a fellow Celestial Dragon.
9Imu
Ruler Of The World
Imu is the sovereign of the World Government. They belong to the Nerona Family, which is one of the twenty founding families of the World Government. Imu is a ruthless individual who only cares about protecting their image.
Imu also seems to be in possession of an unnamed Devil Fruit. Considering they are the most important person in the World Government, it is safe to assume that their Devil Fruit is extremely powerful. Akainu does not know about Imu’s existence, so a showdown between them seems unlikely. However, Imu would emerge on top if the fight did occur.
8St. Jaygarcia Saturn
One Of The Five Elders
St. Jaygarcia Saturn is one of the Five Elders and the Godhead of Science and Defense. He is one of the primary antagonists of the Egghead arc. St. Jaygarcia Saturn arrived on the island with the mission to exterminate Dr. Vegapunk.
It is highly likely that he possesses a Mythical Zoan-type Devil Fruit that allows him to transform into a spider Oni hybrid. Aside from granting him ridiculous strength, the Devil Fruit also grants him increased recovery and stamina.
7Kaido
Strongest Creature In The World
Kaido is a former member of the Rocks Pirates. After the God Valley Incident, he started his own crew and became a famous pirate. Eventually, Kaido was named among the Yonko.
Kaido possesses the Uo Uo no Mi, Model Seiryu, a Mythical Zoan-type Devil Fruit. With its power, he could turn into an enormous azure dragon capable of destroying an entire town with ease. There is a great chance that Kaido and Akainu may have clashed in the past, considering the former’s reckless nature.
6Monkey D. Luffy
Armed With Nika’s Power
Monkey D. Luffy is the youngest pirate to be named one of the Yonko, a position that he gained after his exploits inthe Wano Country arc. The arc was important to Luffy’s development, both as a character and a fighter. Since the Punk Hazard arc, Luffy’s only goal was to take down Kaido so that he could free Wano from his terror, and he finally managed to achieve this goal in Wano.
Presently, Luffy is able to use all three advanced versions of Haki, which is extremely rare, and only a few characters have shown such refined control over their Haki. In addition to his Haki, Luffy also has the power of the Hito Hito no Mi, Model: Nika, which increases his strength by several folds. Luffy has an unsettled score with Akainu, as the latter was responsible for the death of Ace, so they might face each other in the future.
5Shanks
Haki Monster
Shanks is the leader of the Red Hair Pirates and arguablythe strongest character in the series at the moment. He has clashed against other characters, albeit most of them have either been off-screen or they have never escalated into a proper fight.
Shanks is a Haki specialist, and his burst of Conqueror’s Haki managed to scare Admiral Ryokugyu. The Admiral admitted that he did not want to face someone so powerful and left. Shanks and Akainu have clashed in the past, but Akainu was only an Admiral, and he was aware that he stood no chance against Shanks. Needless to say, Shanks is still comfortably stronger than him.
