Quite early on in the One Piece series, the precedence of strength was set once the Admirals were introduced. They were spoken of as being the ultimate military force of the Navy, and subsequently, the World Government as well, so they have been part of the top tier of the series for many years at this point.

For the longest time, fans were convinced that only the most powerful characters in One Piece could stand up to the Admirals, and after their performance in the Marineford arc, this does track. In this article, let's go over the most powerful characters in the setting who can take out the terrifying Navy Admirals.

One Piece: 6 Groups Stronger Than The Holy Knights

There are many powerful groups in One Piece, and many of them are far stronger than even the Holy Knights.

Luffy Was Shown To Fight Kizaru And Saturn At Once

Egghead's Ultimate Battle

No character in the series has grown in power as quickly as Luffy. Upon unlocking his Gear 5 state, he has made himself one of the strongest characters in the series, which was on full display in the Egghead arc, where he managed to take on Kizaru and Saturn at once. Of course, he did very little real damage to the Elder and many believe that Kizaru wasn't even fighting seriously in the first place, but in an all-out battle, Gear 5 Luffy would likely win against most Admirals.

Loki's Haki And Devil Fruit Are Beyond Everyone Else

The Accursed Prince

There is perhaps no character as prodigious as Loki, since he was shown to use Advanced Conqueror's Haki Coating on his hammer Ragnir to strike down Harald, which is a power that not even Luffy has fully learned, without any training. This incredible Haki prowess aside, Loki has perhaps the greatest and most powerful Devil Fruit that we have seen so far across all of One Piece, which easily places him far above the Admirals.

Monkey D. Dragon Is Probably Insanely Powerful

The World's Worst Criminal

Admittedly, placing Dragon on this list is a bit contentious for some due to the fact that he has almost no feats in the series. However, most fans believe that due to his sparse appearances, seeming ability to control the weather, and the fact that he belongs to the legendary Monkey D. Family line, Dragon is actually going to be one of One Piece's most powerful and important characters once he makes his full combat debut.

Kaido's Strength Is Too Great For Any Admiral To Deal With

The World's Strongest Creature

Kaido distinguished himself in the Wano arc as the hardest fight that Luffy has had to date, even after the events of Egghead. He has definitely earned his epithet of World's Strongest Creature, since his mastery of all facets of Haki and his overpowered Devil Fruit allowed him to take on the forces of heroes during the Onigashima Raid by himself, which came almost directly after his 3-day-long fight with Big Mom. Some even believe that if he had not sustained such damage here, he could have defeated Luffy even after his Gear 5 was unlocked.

Shanks Has Already Shown His Superiority Over An Admiral

Showed His Haki Mastery

One Piece first hinted at Shanks' incredible power at the close of the Marineford arc, as he was able to stop a full-powered punch from Akainu using only his Armament Haki. However, a better display was at the end of the Wano arc, where he made his appearance on the island and managed to stop a Navy Admiral dead in his tracks using his Conqueror's Haki from miles away, showing just how far above Ryokugyu, and perhaps most other Admirals, he was.

Mihawk's Insane Strength Is Said To Equal Shanks Himself

The World's Strongest Swordsman

In a world full of pirates and powerful characters, to own the title of the World's Strongest Swordsman definitely speaks to one's legendary strength. Mihawk is the only character in the modern era of the series to own a Black Blade, which has been transformed into such due to him imbuing it with his Haki and strength for years. Since he has always been known as the only equal and rival Shanks has ever had, many believe he could just as easily defeat an Admiral.

Whitebeard Has Already Shown How Much Stronger He Is

The World's Strongest Man

Whitebeard was known as the World's Strongest Man; a title he definitely earned. Not only did he have the most destructive Devil Fruit in the series that was strong enough to destroy the entire world, but he was also a master of all kinds of Haki. Even during the Marineford arc, where his ailing and frail body didn't allow him to use his Conqueror's Haki, he managed to beat the strongest Admiral, Akainu, to a pulp using his Devil Fruit alone.

Gol D. Roger Was The Pirate King For A Reason

The Greatest Pirate

One does not gain the epithet of 'Pirate King' without being an absolute powerhouse of a man. Roger was the captain of the only crew in history to ever find the fabled One Piece treasure, which simply would not have been possible if he wasn't insanely powerful. Roger didn't have a Devil Fruit, so he owed all of his strength to a perfect mastery of all forms of Haki, and he was outright told to regularly defeat the Holy Knights, which is a group that's even above the Admirals.

Rocks D. Xebec Was The Captain Of The Strongest Crew Ever

The Greatest Pirate

To captain what the world calls the strongest crew in history, one must be an insanely powerful combatant. Rocks D. Xebec was said to be Roger's greatest rival who also owed all of his strength to Haki alone, cementing himself as perhaps the greatest and most dangerous pirate of all time. He was so powerful that he even managed to kill an Admiral as a rookie after breaking into Marijoa, which is a feat no one else has ever done.

King Harald Was The Most Powerful Giant Of All Time

Rocks' Equal

King Harald was the king of Elbaf during the era of Roger and Rocks. Belonging to the lineage of Ancient Giants, Harald was already supposed to be exceptionally strong due to his immense physicality. However, on top of this, Harald was one of the most powerful users of the various forms of Haki that we have ever seen, to the point where he was an equal to Rocks in every way as the two even fought to a standstill multiple times and created the greatest Conqueror's Haki clash in history.
