One Piece: 9 Non-Yonko Characters Who Can Defeat An Admiral

by

I’m completely fascinated by the Marines! They’re basically the guardians of the sea, always tracking down criminals and protecting those who can’t protect themselves. For centuries, they’ve been the main force fighting against pirates, and honestly, I think the world would be a much more dangerous place without their dedication. It’s really cool how they structure things too – you earn your rank through experience and everything you accomplish, so it’s all about proving yourself!

The rank of Admiral is incredibly prestigious, and historically, only three individuals held that title at any given time. They’re considered the world’s most powerful military force and possess immense strength. However, even Admirals aren’t unbeatable. Here are some characters from One Piece who have the power to defeat one.

9. Silvers Rayleigh

  • Right Hand Of Pirate King

Rayleigh is a hugely significant character in the series, largely because he trained Luffy in the use of Haki. As a master of Haki himself, he’s capable of using its most advanced techniques – a skill very few possess. Everyone acknowledges his incredible strength; even Blackbeard avoided fighting him. Rayleigh previously clashed with Kizaru at Sabaody Archipelago, and Kizaru conceded that he couldn’t win against the ‘Dark King’.

8. Sengoku

  • Former Fleet Admiral Of The Navy

Sengoku is a highly respected veteran of the Navy, known for both his incredible strength and brilliant strategies. Friends and foes alike acknowledge his tactical prowess; his commands were crucial to the Marines’ victory at Marineford. He has a rare and powerful Devil Fruit – a Mythical Zoan type – which allows him to transform into a golden Buddha and grants him shocking abilities comparable to the Gura Gura no Mi.

7. Dracule Mihawk

  • World’s Strongest Swordsman

Mihawk is a key member of the Cross Guild and consistently ranks among the world’s strongest fighters. He’s a formidable opponent, having battled someone as powerful as Shanks. Aside from a brief clash with Vista, Mihawk hasn’t had a serious fight in years. Even without recent displays of his power, he’s still widely considered the greatest swordsman in the world, with skills that no one can match.

6. The Gorosei

  • Imu’s Most Trusted Underlings

This group of five people holds the second-highest level of power in the world, essentially controlling global events. While they’ve been presented as being uninvolved in direct conflict, that’s a misleading portrayal. They are incredibly powerful, with abilities comparable to natural disasters. Each member possesses the power of a Devil Fruit, allowing them to transform into legendary creatures, and they are also masters of Haki, making them exceptionally dangerous.

5. Imu

  • Ruler Of The World

Imu used to be a complete enigma, but now we know just how powerful he is – he’s currently unmatched in the world. He fully appeared during the Elbaph arc and swiftly thwarted Luffy and his crew’s plans. Even Loki couldn’t inflict any damage on him, demonstrating Imu’s overwhelming strength.

4. Sakazuki

  • Fleet Admiral Of The Navy

Akainu firmly believes in absolute justice and is a major threat to all pirates. He sees anyone obstructing justice as evil and believes they should be destroyed. He’s incredibly powerful, possessing a rare Devil Fruit ability and strong Haki, which allowed him to win a grueling ten-day battle against Aokiji.

3. Loki

  • Accursed Prince Of Elbaph

The Elbaf arc revealed Loki, a remarkably powerful character and the rightful heir to Harald’s throne. He quickly proved to be one of the strongest in One Piece, demonstrated by his ability to defeat Harald, who had just received a significant power boost from Imu. More recently, Loki even battled Imu himself, putting up a strong fight.

2. Scooper Gaban

  • Left Hand Of The Pirate King

Gaban used to sail with the Roger Pirates and is incredibly powerful, often compared to Rayleigh in terms of strength. He proved his abilities by easily defeating a God Knight. Unlike some pirates, Gaban doesn’t rely on a Devil Fruit; he’s a master of Haki. Given Rayleigh’s past victory against Kizaru, many believe Gaban is capable of achieving the same feat.

1. Monkey D. Garp

  • Hero Of The Marines

Though Garp is ‘only’ a Marine vice admiral, he’s considered one of the strongest Marines ever. He doesn’t rely on a Devil Fruit’s power, but has instead trained his Haki to an incredible degree. A single punch from Garp is devastating enough to destroy an entire island. He was even strong enough to fight Aokiji on equal footing, and only lost when the Blackbeard Pirates interfered.
