This article contains spoilers for One Piece.
Yonko are the most terrifying pirates in the One Piece world. Known to be the rulers of the New World, the Yonko are powerful and lead some of the strongest crews in the series.
Their power is such that not many would want to cross paths with them, let alone exchange blows with them. But these characters could definitely take them on, or even outright destroy them, even in a 1v1 battle.
Boa Hancock

Haki: Armament, Observation, Conqueror's
Boa Hancock is the Pirate Empress and leader of the Kuja Pirates. Hancock hasn't had many moments since the events of the Summit War, but Oda has proven on multiple occasions that she's a character that could take on Yonko as well One Piece.
During the Marine Raid of Amazon Lily, Blackbeard, as well as two of his best crew members, infiltrated the chaos. However, Blackbeard decided not to take on Hancock directlyand for very good reason. Blackbeard himself stated that Hancock would turn him to stone instantly and defeat him if he didn't approach her carefully. Blackbeard had to resort to cowardly moves to take her down.
Scopper Gaban

Devil Fruit: None

Haki: Armament, Observation, Conqueror's
Scopper Gaban, Roger's left-hand man, is well past his prime at the moment. But during his prime, Gaban was definitely unstoppable.
Fans have yet to see young Scopper Gaban go all out, but narratively, Oda has already revealed that he is the type of character who could single-handedly defeat a Yonko. Gaban was stated to be on the same level as Roger. In other words, Gaban is closer to the level of the Pirate King than a Yonko.
Silver's Rayleigh

Devil Fruit: None

Haki: Armament, Observation, Conqueror's
Silvers Rayleigh, also known as the Dark King, was one of the most fearsome pirates of his time. As the Pirate King's right-hand man, Rayleigh was definitely one of the strongest pirates to sail the Grand Line. Like Gaban, fans have yet to see him go all out in his prime. However, he was also stated to be related to Roger in power.
Regardless, Rayleigh has proven that even at his advanced age he could cause a lot of trouble for a Yonko or an Admiral.
Kozuki Oden

Haki: Armament, Observation, Conqueror's
Kozuki Oden was a legendary pirate who sailed alongside the Whitebeard Pirates and Roger Pirates. Odin's swordsmanship was in a league of its own, and he proved just how strong he was by almost single-handedly killing Yonko Kaido.

Yonko are powerful, but they are not the only strong pirates in One Piece.
Odin was the first person to really hurt Kaido. He left a deep scar for Kaido to remember for years to come, so much so that Kaido sees him as one of the strongest. Odin would undoubtedly have killed Kaido if he hadn't had his family as leverage against him.
Monkey D. Garp

Devil Fruit: None
-
Haki: Armament, Observation, Conqueror's
When it comes to legendary marines, none are as great as Monkey D. Garp. Garp is known as the hero of the Marines for a reasonand despite his rank as Vice Admiral, his power is far beyond that.
After all, Garp was one of the Pirate King's biggest rivals. Garp showed his strength at God Valley by taking down Domi Reversi'd Rock's D. Xebec with Roger. Even in his old age, Garp also single-handedly destroyed the Blackbeard Pirates.
King Harald

Devil Fruit: None

Haki: Armament, Observation, Conqueror's
Harald is the late king of Elbaf and the greatest king in the country's history. He was so fierce that he was even known as the strongest king the land of giants has ever had, and fans can understand why.
7 Users Of God Level Haki in one piece
These haki users in One Piece are the greatest. Some would even describe their haki as god level.
Harald was on the same level as Rocks D. Xebeca pirate who was probably above the level of even a Yonko. Harald is definitely a step ahead of the average Yonko in One Pieceespecially when he's at his strongest, where he got Immortality and a strength buff from Imu.
Rocks D. Xebec
-
Devil Fruit: None
-
Haki: Armament, Observation, Conqueror's
Rocks D. Xebec is a legendary character. Fans finally got to know more about him during the Elbaf flashback. Oda confirmed that Rocks D. Xebec was on a whole other leveland led a crew of future Yonkos.
Rock's D. Xebec was so impressive that he was one of the people Kaido saw as the strongest. His power was shown repeatedly during the flashback, as he was able to easily kill an Admiral and even take down Garling Figarland. Rock's D. Xebec had even more potential in him, but his life ended prematurely as he was forced to face Imu far too soon.
Gol D. Roger
-
Devil Fruit: None
-
Haki: Armament, Observation, Conqueror's
The late Pirate King, Gol D. Roger is a character whose true strength has finally come to light. In the past, fans used to wonder if Roger was on par with a Yonko, or if the Pirate King was in a league of his own. The answer has become obvious, and the average Yonko would be no challenge for Roger.
After all, before even reaching his prime, Roger was able to fight and take down the likes of a Domi Reversed Rocks D. Xebec with the help of Garp.
One Piece: Oda has already confirmed who is the strongest between the Admirals and the Yonko
Fans have always wondered how the Admirals compare to the Yonko in power. Oda already confirmed this in One Piece.
Imu
-
Devil Fruit: Nameless fruit
-
Haki: Armament, Observation, Conqueror's
If there is a character that could take on anyone One Pieceit definitely is Saint Imu, the secret ruler of the world.
Imu is on a completely different level compared to everyone living in One Piece. In God Valley, Imu took on 6 top tiers – Rocks, Whitebeard, Big Mom, Kaido, Roger and Garp. All of these characters are Yonko level, or have Yonko potential. Imu even one-shot Rocks D. Xebec before turning him into a demon slave. No other character has shown such feats. Imu could easily take down a Yonko in a battle, and even characters above that level.
