One Piece: 10 Strongest Marines

The Marines in One Piece play a vital role in maintaining order across the seas, standing as the World Government's military power. From Admirals to Vice Admirals, these individuals possess extraordinary abilities and strength that make them some of the most formidable forces in the world.  

With various Devil Fruits, mastery of Haki, and military expertise, the strongest Marines are a constant threat to pirates. Let’s explore the ten strongest Marines ranked by their popularity, based on their strength, abilities, and pivotal roles in One Piece.

10. Vice Admiral Momonga

Vice Admiral Momonga is a seasoned and skilled Marine officer, known for his strong sense of duty and ability to keep calm under pressure. While he doesn’t possess a Devil Fruit power, his mastery of both Haki and swordsmanship make him an exceptional fighter. 

Momonga played a significant role in the Marineford War and was a key figure during the Impel Down arc, escorting Boa Hancock to meet with the imprisoned Ace. His no-nonsense attitude and loyalty to the Marines make him one of the most respected vice admirals in the organization.

9. Vice Admiral Smoker

Vice Admiral Smoker, also known as "White Chase," wields the power of the Moku Moku no Mi, a Logia-type Devil Fruit that allows him to create, control, and become smoke. First introduced in Loguetown, Smoker is a tenacious Marine who relentlessly pursues Luffy and other pirates. 

While he may not be an Admiral, his determination, strong sense of justice, and skill in using his jitte (weapon tipped with Sea Prism Stone) make him a formidable foe. Smoker’s popularity comes from his strong moral compass and ongoing rivalry with Luffy.

8. Fujitora (Admiral Issho)

Admiral Fujitora, also known as Issho, is a newer addition to the ranks of Marine Admirals, first introduced in the Dressrosa arc. He wields the Zushi Zushi no Mi, a Paramecia-type Devil Fruit that grants him the ability to manipulate gravity. 

Fujitora’s morals and vision of true justice often lead him to clash with the government he serves. His gravity-based powers allow him to summon meteors and create massive gravitational forces, making him an incredibly powerful Marine. His strong ideals and blindness make his character interesting.

7. Vice Admiral Tsuru

Though often overlooked, Vice Admiral Tsuru is one of the most respected and experienced Marines. Her Wash-Wash Fruit (Woshu Woshu no Mi) allows her to "wash" people and objects as if they were laundry, draining evil intent and immobilizing her enemies. 

Tsuru's intelligence and tactical mind make her a key figure in the Marines' strategy, often advising others in major operations. As a peer of Garp and Sengoku, Tsuru’s longevity in the story and her commanding presence give her a unique place among the strongest Marines.

6. Kizaru (Admiral Borsalino)

Admiral Kizaru, also known as Borsalino, possesses the power of the Pika Pika no Mi, a Logia-type Devil Fruit that allows him to move and attack at the speed of light. His laid-back demeanor contrasts with his devastating combat abilities, making him one of the most dangerous Marines. 

Kizaru’s role in several key battles, such as at the Sabaody Archipelago and the Marineford War, showcases his immense strength and importance. His ability to unleash light-based attacks with blinding speed and power solidifies his place as one of the top Admirals.

5. Admiral Ryokugyu (Green Bull)

Admiral Ryokugyu, also known as Green Bull, is one of the newest additions to the ranks of Marine Admirals. Though much about his past remains a mystery, his introduction during the Reverie arc showcased his overwhelming power and devotion to the Marines. 

Ryokugyu possesses the Mori Mori no Mi, a Logia-type Devil Fruit that allows him to control and generate plant life. His ability to absorb nutrients from his surroundings and grow plants makes him a powerful foe. His carefree attitude hides his strong dedication to Marine justice, making him one of the most feared Admirals today.

4. Aokiji (Former Admiral Kuzan)

Kuzan, also known by his alias Aokiji, was a Marine Admiral before resigning from his position. His powers stem from the Hie Hie no Mi, a Logia-type Devil Fruit that allows him to create, control, and become ice. 

Known for his calm and relaxed attitude, Aokiji is one of the most powerful characters in One Piece. His clash with Akainu over the position of Fleet Admiral left him with a lasting injury. Aokiji’s moral ambiguity and subsequent departure from the Marines make him a fan-favorite character.

3. Fleet Admiral Akainu (Sakazuki)

Fleet Admiral Sakazuki, also known as Akainu, is a ruthless and fearsome leader in the Marines. His Magma-Magma Fruit (Magu Magu no Mi), a Logia-type Devil Fruit, grants him control over magma, allowing him to unleash devastating attacks with destructive power. 

Akainu's unwavering belief in absolute justice drives his brutal approach to eliminating pirates. His battle with Aokiji for the Fleet Admiral position was one of the most significant moments in the series. Akainu’s cold-hearted nature and immense power make him one of the most feared Marines.

2. Vice Admiral Garp

"Hero of the Marines" Monkey D. Garp is known for his immense strength and his refusal to accept promotions to Admiral, preferring to retain his independence. Garp is one of the few characters able to stand against the Pirate King, Gol D. Roger, in combat, relying solely on his Haki and raw physical power. 

He plays a major role in One Piece, especially with his connection to Luffy and his status as one of the most iconic Marines. Garp’s history with legendary pirates makes him a beloved figure among fans.

1. Fleet Admiral Sengoku

Sengoku's influence on the Marines as a Fleet Admiral during some of the most critical events in One Piece history is unmatched. His Mythical Zoan-type fruit, the Hito Hito no Mi, Model: Daibutsu, allows him to transform into a giant golden Buddha, symbolizing wisdom and power. 

His participation in the Marineford War and his leadership throughout the Great Pirate Era left a lasting impact. Sengoku’s analytical mind, coupled with his combat prowess, makes him the most iconic Marine, standing as a testament to the complex justice of the organization.
