The Marine organization is one of the Three Great Powers of the One Piece world. Known to be the military face of the World Government, the Marines are quite fearsome, and their strongest members are none other than the Admirals.

Usually, the Marines feature three regular Admirals, and one Fleet Admiral who stands as the single most powerful person in the organization. The current Admirals are Greenbull, Fujitora, and Kizaru, while Akainu became the Fleet Admiral. With powerful Devil Fruits and strong Haki, the Admirals are certainly very strong, but there are definitely characters who could defeat them.

Boa Hancock

  • Devil Fruit: Mero Mero no Mi
  • Type of Devil Fruit: Paramecia
  • Haki: All Three

Boa Hancock is a powerful, yet often underestimated One Piece character. She’s known as the Pirate Empress and currently stands as one of One Piece’s strongest pirates.

Boa Hancock is a master of all Haki types. On top of that, she has a broken Devil Fruit called Mero Mero no Mi. With this fruit, she can one-shot most enemies by turning them to stone. While usually her powers require attraction to work, she can also petrify her enemies without using this ability. Even Yonko Blackbeard chose not to fight Hancock head-on, clearly stating that he would be instantly turned to stone. This just goes to prove that Hancock can most definitely defeat an Admiral.

Hawkeye Mihawk

  • Devil Fruit: None
  • Type of Devil Fruit: N/A
  • Haki: Armament, Observation

Mihawk is known as the World’s strongest Swordsman. His skills with the blade are unmatched, and many would consider him the most powerful former Shichibukai.

Mihawk was a rival of Shanks long ago, and he should definitely be around the level of a Yonko. In that regard, Mihawk should easily be able to take on any Admiral.

Five Elders

  • Devil Fruit: Unknown
  • Type of Devil Fruit: Devil Contact
  • Haki: All Three

The Five Elders are the World Government’s most powerful force. They are currently made up of Nusjuro, Mars, Warcury, Ju Peter, and Garling. Each one of these characters could easily defeat an Admiral.

None of the Admirals have been confirmed to even be Conqueror’s Haki users. In other words, the Admirals can’t even scratch them due to their immortality. Even without their immortality, the Gorosei would still come out on top.

Big Mom

  • Devil Fruit: Soru Soru no Mi
  • Type of Devil Fruit: Paramecia
  • Haki: All Three

Charlotte Linlin, also known as Big Mom, is known as One Piece’s strongest female character, and it is very easy for fans to see why. Big Mom was at the head of a powerful Yonko crew, the Big Mom Pirates.

Aside from Buggy, all the Yonko in One Piece are superior to the Admirals. This was especially obvious at the end of Wano and on Egghead. Big Mom, with her superior Haki and Devil Fruit mastery, could easily come out victorious against any Admiral.

Kaido

  • Devil Fruit: Uo Uo no Mi, Model: Seiryu
  • Type of Devil Fruit: Mythical Zoan
  • Haki: All Three

Kaido is one of the most impressive One Piece characters that fans have seen go all out. As the main villain of Wano, he was no easy enemy to defeat. Kaido has some of the best Haki feats in One Piece, and on top of that, he has the powers of a Mythical Zoan Dragon fruit.

Even with Gear 5, winning against Kaido wasn’t easy for Luffy. Meanwhile, Luffy was toying with Kizaru in Gear 5. This is more than enough proof that Kaido is superior to the average Admiral. Defeating one would be no hard task for him. In fact, even Green Bull openly admitted that he would never even dare to come to Wano if Kaido were alive.

Monkey D. Luffy

  • Devil Fruit: Hito Hito no Mi, Model: Nika
  • Type of Devil Fruit: Mythical Zoan
  • Haki: All Three

Monkey D. Luffy has very recently joined the ranks of Yonko following the events of Wano and the defeat of Kaido. In just a few arcs, Luffy has grown greatly in power. His newest power-up, Gear 5, makes him insanely powerful.

Previously, Luffy and his crew were destroyed on Sabaody by Kizaru. Now, however, no Admiral can take down the captain of the crew. In Egghead, Luffy was toying with Kizaru, and he could have easily defeated him in an all-out battle.

Monkey D. Dragon

  • Devil Fruit: Unknown
  • Type of Devil Fruit: Unknown
  • Haki: All Three

Monkey D. Dragon is the leader of the Revolutionary Army. A former Marine, Dragon ended up leaving the organization following the tragic events of God Valley.

Dragon’s strength greatly grew following this event, and he has since become one of One Piece’s strongest characters. Dragon’s full power remains a mystery, but it would be shocking if he couldn’t, at the very least, defeat a Marine Admiral.

Blackbeard

  • Devil Fruit: Yami Yami no Mi, Gura Gura no Mi
  • Type of Devil Fruit: Logia and Paramecia Respectively
  • Haki: Armament, Observation

Blackbeard is one of the most dangerous individuals in One Piece. Descending from Rocks D. Xebec and Davy D. Jones, Blackbeard is not someone to underestimate.

He is a unique individual, and the only known person to be able to consume more than one Devil Fruit. At the moment, Blackbeard has two of One Piece’s strongest fruits — the Yami Yami no Mi, and the Gura Gura no Mi. With these two powers, no Admiral can stand a chance against him.

Rocks D. Xebec

  • Devil Fruit: None
  • Type of Devil Fruit: N/A
  • Haki: All Three

Just the name of Rocks D. Xebec is legendary. Rocks commanded the Rocks Pirates and led the likes of Whitebeard, Big Mom, and Kaido, among others.

Oda has already confirmed that Rocks D. Xebec could easily defeat an Admiral as he killed an unknown Admiral during his era without even breaking a sweat, and this was likely before he even went all-out. Rocks had even more room to grow, but sadly, he died far too early.

Harald

  • Devil Fruit: None

  • Haki: All Three

Harald was the King of Elbaf. He was so strong that Elbaf openly labelled him as the strongest King in history. With Elbaf’s deep history, this is a very impressive title. Harald was on the level of Rocks D. Xebec, someone who easily killed an Admiral, and he could possibly have even surpassed him.

After making a pact with Imu, Harald gained immortality and other strength boosts. He could easily deal with the Admirals.

Loki

  • Devil Fruit: Elbaf's Legendary Devil Fruit
  • Type of Devil Fruit: Mythical Zoan
  • Haki: All Three

Loki is the Accursed Prince of Elbaf and a force to be reckoned with. He has a yonko level bounty of 2.6 billion berries, which is also considered special by the World Government. His strength has been hyped up by Oda multiple times now.

It’s said that only Shanks was able to take him down when all of Elbaf failed to do just that. With Ragnir and a legendary Devil Fruit in his possession, Loki could swiftly defeat any average Admiral. In fact, he could even overpower the amped up Harald who was far stronger than even the Pirate King Roger.
