This article contains spoilers for One Piece.
Yonks are the most feared pirates of the One Piece world. Known to be the rulers of the New World, the Yonko are powerful and lead some of the strongest crews seen in the series.
Their power is such that few would want to cross paths with them, let alone do business with them. However, these characters could definitely take them on, or even outright destroy them, even in a 1v1 battle.
Boa Hancock

Devil Fruit: Mero Mero no Mi

Haki: Armament, Observation, Conqueror
Boa Hancock is the Pirate Empress and leader of the Kuja Pirates. Hancock didn't have many moments after the events of the Summit War, but Oda proved that on several occasions she's a character that could take on even a Yonko One piece.
During a naval raid on the Amazon Lily, Blackbeard, as well as two of his best crew members, were thrown into chaos. However, Blackbeard decided not to go head-to-head with Hancockand for very good reasons. Blackbeard himself stated that Hancock would instantly turn him to stone and defeat him if he didn't approach her carefully. Blackbeard had to resort to cowardly steps to take her down.
Scopper Gaban

Devil Fruit: None

Haki: Armament, Observation, Conqueror
Scopper Gaban, Roger's left-hand man, is far from his best at the moment. At the time of its greatest glory, however Gaban was absolutely unstoppable.
Fans have yet to see young Scopper Gaban go all out, but story-wise, Oda has already revealed that he is the type of character that could defeat a Yonko by himself. Gaban was said to be on par with Roger. In other words, Gaban is closer to Pirate King level than Yonko.
Silver Rayleigh

Devil Fruit: None

Haki: Armament, Observation, Conqueror
Silvers Rayleigh, also known as the Dark King, was one of the most feared pirates of his era.. As the Pirate King's right-hand man, Rayleigh was definitely one of the most powerful pirates to sail the Grand Line. Much like Gaban, fans have yet to see him go all out in his prime. However, he was also said to be relative to Roger in power.
Either way, Rayleigh had proven that even in his old age he could cause a Yonko or an Admiral quite a bit of trouble.
Kozuki Oden

Devil Fruit: None

Haki: Armament, Observation, Conqueror
Kozuki Oden was a legendary pirate who sailed alongside the Whitebeard Pirates and Roger Pirates. Oden's swordsmanship was in a league of its own, and he proved just how strong he was when he almost single-handedly killed Yonko Kaido.
The 9 Strongest Non-Yonko Pirates in One Piece, Ranked
Yonko are powerful, but they are not the only powerful pirates in One Piece.
Oden was the first person to actually hurt Kaid. He left Kaido with a deep scar that he would remember for years to come, so much so that Kaido considers him one of the strongest. Oden would undoubtedly have killed Kaid if she hadn't used her family as leverage against him.
Monkey D. Garp

Devil Fruit: None
-
Haki: Armament, Observation, Conqueror
When it comes to legendary marines, none are as massive as Monkey D. Garp. Garp is known as the hero of the Marine Corps 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 greatest rivals. Garp showed his power at God Valley by defeating Domi Reversi'd Rocks D. Xebec with Roger. Even in his old age, Garp almost single-handedly destroyed the Blackbeard Pirates.
King Harald

Devil Fruit: None
-
Haki: Armament, Observation, Conqueror
Harald is the late King of Elbaf and the greatest king in the land's history. He was so fierce that he was even known as the strongest king the land of giants ever had, and fans can see why.
7 God level Haki users in one piece
These haki users in One Piece are the greatest. Some would even describe their haki as god level.
Harald was on par with Rocks D. Xebeca pirate who was probably out of step with even a Yonka. Harald is definitely a step ahead of the average Yonk in One Pieceespecially at his strongest where he got Immortality and strength buff from Imu.
Rocks D. Xebec
-
Devil Fruit: None
-
Haki: Armament, Observation, Conqueror
Rocks D. Xebec is a legendary figure. Fans finally learned more about him during the Elbaf flashback. Oda confirmed that Rocks D. Xebec was on a completely different leveland led a crew of future Yonks.
Rocks D. Xebec was so impressive that he was one of the people Kaido saw as the strongest. His strength was repeatedly shown during the flashback as he was able to easily kill the Admiral and even take down Garling Figarland. Rocks D. Xebec had even more potential in him, but his life ended prematurely as he was forced to face Im too soon.
Go D. Roger
-
Devil Fruit: None
-
Haki: Armament, Observation, Conqueror
The late Pirate King, Gol D. Roger is a character whose true power has finally come out. Previously, fans wondered if Roger was on the level of a Yonka, or if the Pirate King was in a league of his own. The answer became obvious and an average Yonko would be no challenge for Roger.
After all, even before reaching his best budgets, Roger was able to fight and defeat the likes of Domi Reversed Rocks D. Xebec with the help of Garp.
One Piece: Oda has already confirmed who is stronger between the Admirals and Yonk
Fans have always wondered how the Admirals compare to Yonk in power. Oda already confirmed this in One Piece.
Im
-
Devil Fruit: An unnamed fruit
-
Haki: Armament, Observation, Conqueror
If there is one character that could take on anyone One pieceit definitely is Saint Imu, the secret Ruler of the World.
Imu is on a whole other level compared to anyone alive in One Piece. In God's Valley, Imu got the 6 highest levels – Rocks, Whitebeard, Big Mom, Kaido, Roger and Garp. All of these characters are Yonko level or have Yonko potential. Imu even one-shots Rocks D. Xebec before turning him into a demon slave. No other character has performed such feats. Imu could easily defeat a Yonko in battle and even characters outside of this level.
