The Marines, an immense and formidable organization in the world of One Piece, serve as the peacekeepers for the World Government. Within their ranks, there are numerous formidable individuals, contributing to the organization's reputation as a fearsome force throughout the One Piece world.
For years, the Marines have been relentless in their pursuit of pirates and other offenders. However, a shift occurred with the emergence of the Cross Guild. This group placed bounties on the heads of the Marines, leading to a surge of criminals targeting them. Even the general public turned their backs on the Marines. Given the discrepancy in power levels, it is unsurprising that certain Marines possess higher bounties compared to others.
6 Koby
Koby, once a timid boy with big dreams, has transformed into a Marine Captain and protege of Garp. Initially unable to stand up to Alvida, his life changed when he crossed paths with Luffy, who rescued him from her clutches.
Under the guidance of Garp, Koby and Helmeppo joined the Marines and underwent rigorous physical training, resulting in the development of Koby's strength and speed. Now proficient in Kenbunshoku Haki and various Rokushiki techniques, Koby played a crucial role in the Rocky Port incident, earning him the title "The Hero." Unlike most Marine Captains with a bounty of 100 million berries, Koby stands out with a bounty of 500 million berries, reflecting his exceptional reputation.
5 Monkey D. Garp
Monkey D. Garp is renowned as the Marine's most formidable combatant in history. His incredible physical strength was honed through rigorous training and the use of Marine battleships as his punching bags. Garp's sheer might enables him to effortlessly demolish mountains with his bare hands. These intense exercises paid off, as he was the sole Marine to successfully corner Gol D. Roger.
Moreover, Garp played a crucial role in the infamous God Valley incident, partnering with Roger to bring down the formidable Rocks Pirates. His involvement in this event earned him the title "Hero of the Marines." Despite holding the rank of Vice Admiral, Garp possesses a bounty of 3 billion berries, surpassing expectations. It goes without saying that if Garp were in his prime, his bounty would undoubtedly be even higher.
4 Ryokugyu
During the time skip, Ryokugyu enlisted in the Marines and became one of the two newly appointed Admirals. He adheres to the belief of Suicidal Justice, which is connected to his past. Possessing the Mori Mori no Mi, a Logia-type Devil Fruit, he possesses the ability to manipulate and create plant life at will. Being aware of his Devil Fruit's vulnerability to fire, he has successfully enhanced the plants' resistance to some extent. Upon arriving in Wano, Ryokugyu engaged in a battle against Momonosuke and his followers. Although he came close to defeating them, he abruptly halted upon sensing Shanks' powerful release of Conqueror's Haki. As an Admiral, Ryokugyu carries a bounty of 3 billion berries.
3 Kizaru
Kizaru, the oldest and arguably the strongest Admiral, remains an enigma due to his mysterious background. His allegiance to Ambiguous Justice raises questions about his motives. Most of the time, Kizaru appears disinterested in his surroundings, but beware when he takes things seriously, as those in close proximity are in grave danger. His unforgettable appearance in Sabaody, effortlessly defeating numerous Supernovas, still lingers in the minds of fans.
With his Pika Pika no Mi powers, Kizaru becomes an exceptionally hazardous individual. This Devil Fruit grants him unparalleled mastery over light itself. His ability to move at the speed of light renders his attacks nearly impossible to evade. The sheer force behind Kizaru's kicks is so immense that they can demolish towering trees in Sabaody. Possessing both Kenbunshoku and Busoshoku Haki, Kizaru showcases impeccable control over both forms of this special ability. Currently, he journeys towards Egghead alongside one of the Five Elders. Notably, his extraordinary exploits have earned him a staggering bounty of 3,000,000,000 berries.
2 Fujitora
Fujitora, without a doubt, is the Admiral known for his kindness and sensibility. His affiliation with the organization came after the events of the Paramount War, and he quickly gained recognition for his immense power. Doflamingo himself referred to Fujitora as a monster, a testament to his formidable strength. Despite being visually impaired, Fujitora possesses exceptional Kenbunshoku Haki, allowing him to navigate battles effortlessly.
Similar to his fellow Admirals, Fujitora possesses an incredibly powerful Devil Fruit ability. Specifically, he wields the Zushi Zushi no Mi, a Paramecia-type Devil Fruit that grants him control over gravitational forces. Utilizing this ability, Fujitora is capable of summoning gigantic meteors from the heavens, obliterating anything in their path within mere seconds. While Fujitora has yet to unleash his full might in combat, it is certain that this will change during the final saga. Despite being a relatively recent addition to the Marines, Fujitora holds an impressive bounty of 3 billion berries.
1 Akainu
Akainu, the current Fleet Admiral of the Marines, emerged victorious in a ten-day battle against Aokiji, his fellow Admiral, leading to a change in the climate of Punk Hazard. Despite sustaining injuries, Akainu claimed the position and now stands as the most formidable Marine in the world of One Piece. His relentless pursuit of justice is matched only by his ruthlessness. Possessing the devastating power of the Magu Magu no Mi, he wields complete control over magma, a power he has utilized to eliminate Ace, disfigure half of Whitebeard's face, and inflict harm upon Luffy. Though unconfirmed, it is speculated that his bounty stands at approximately 4 billion berries.
