Over the years, One Piece has introduced a lot of new and strong characters. These characters are blessed with ridiculous strength, and they have displayed it on several occasions. The power of these characters separates them from ordinary characters.
Every strong character in One Piece has one or two attacks that they use to overwhelm their opponent. Some of these attacks are powerful enough to destroy a wide area with ease. Many of these moves are powered by Haki while the others are a combination of devil fruit and Haki. What are the strongest attacks in One Piece (so far)?
Updated on February 25, 2022, by Suzail Ahmad: With every passing chapter, more and more mysteries are being unraveled in One Piece. The old and the new generation is caught in a bitter fight for supremacy. So far the Wano Country arc has shown the fans the strength of the Yonko and how close the members of the Worst Generation are to toppling them. The arc has produced some intense fights, and there is no doubt that before the end of the arc, there will be more battles. With so many strong characters showing off their abilities, a few more of the most powerful attacks in One Piece have been added to this article.
15 Puncture Willie
Puncture Willie is a technique that was used by Trafalgar Law in his fight against Big Mom. In this attack, Law pierces his opponent with Kikoku, pinning them to the ground in the process. The sword keeps on extending, and it phases through everything in its way.
Once it reaches a specific depth, Law releases a shockwave that can cause heavy damage to everyone in the vicinity. This attack resulted in a massive crater near the Flower Capital.
14 Punk Clash
Punk Clash is an attack that requires Eustass Kid to use his devil fruit awakening. In this move, Kid first uses Assign on his opponent, and once they are magnetized, he increases the level of attraction, which causes all kinds of metallic objects to be drawn towards the target. The target can easily die from being crushed underneath the chunks of metal.
13 Mother's Visit Cannon: 3000 Leagues of Misery
Big Mom has no shortage of attacks, and it is mainly due to her incredibly versatile devil fruit. Even after taking several attacks from awakened devil fruit users, Big Mom wasn't ready to go down.
For this particular attack, Big Mom creates a giant homie that is made of lightning and fire. This homie is capable of acting independently, and it follows Big Mom's orders without fail.
12 Himorogiri
Himorogiri is an attack that was used by Yamato in his fight against Kaido. The attack uses Yamato's devil fruit ability, which makes it more powerful. Yamato enters his hybrid form and uses his ability to create ice to form a swirl of ice around his weapon.
Then Yamato uses the club to strike his opponent. Kaido tried to block this attack but ended up getting knocked to the ground.
11 King of Hell, Three-Sword Serpent: 103 Mercies Dragon Damnation
This attack was used by Roronoa Zoro in his fight against Kaido's right-hand man, King. The attack is infused with both Haoshoku and Busoshoku Haki.
Once Zoro charges towards his opponent, the stored Haki is released towards his opponent in the form of a slash. The attack was powerful enough to defeat King, who was using his strongest attack.
10 King Kong Gun
It is the most powerful attack that Luffy has used in the series so far. He used this attack in his fight against Donquixote Doflamingo. King Kong Gun is a Gear Fourth attack, and it is capable of leveling an entire plateau.
Whilst using Gear Fourth, Luffy blows extra air into his right arm, increasing its size. King Kong Gun has enough power to shatter Doflamingo's God Thread and Spider Web techniques at the same time.
9 Maser Cannon
Big Mom's arsenal is filled with a variety of attacks that allow her to overwhelm all kinds of opponents. Maser Cannon is a combination attack in which Big Mom uses three of her most powerful homies— Prometheus, Hera, and Napoleon.
In this attack, the three homies combine their powers and then Big Mom swings Napoleon, which unleashes an extraordinarily powerful beam that can go through the skin of a dinosaur very easily. Once the beam pierces the flesh of an individual, it follows up a big explosion.
8 Conqueror of Three Worlds Ragnaraku
One of the Yonko, Kaido is a ridiculously powerful character. He ate the Uo Uo no Mi, Model: Seiryu, which is a mythical zoan type devil fruit. The devil fruit allows Kaido to turn into a ginormous eastern dragon and its hybrid.
While in his hybrid form, Kaido's power and speed reach astounding levels. In order to perform Conqueror of Three Worlds Ragnaraku, Kaido covers his kanabo with Conqueror's Haki and uses it to attack an opponent with great strength. This attack was strong enough to momentarily knock out Luffy.
7 Garp's Fist
Monkey D. Garp is heralded as the "Hero of the Marines." In his long career as a Marine, Garp has fought against some of the most infamous pirates, which cemented his place as the strongest Marine in the series. Garp does not have a devil fruit, however, that didn't stop him from fighting pirates.
His strength as a fighter was even acknowledged by Gol D. Roger. Garp's strength lies in his tremendous Haki. In his prime, Garp was able to destroy several mountains with his Haki-coated fists.
6 Divine Departure
Despite not having a devil fruit, Gol D. Roger's strength in combat was almost unparalleled, with only a handful of characters being able to rival his power. Roger was an easygoing individual who enjoyed fighting strong opponents.
During his first encounter with Kozuki Oden, Roger couldn't hold himself back because of the thrill of fighting a powerful opponent. In this attack, Roger imbued his sword with Conqueror's Haki and swung it which led to the creation of a mighty slash that sent Oden flying.
5 Black Hole
Blackbeard's rise to the position of a Yonko was largely down to his devil fruit power. His Yami Yami no Mi is one of the most overpowered devil fruits in the series. The devil fruit allows him to cancel the abilities of other devil fruits.
Blackbeard used Black Hole for the first time in his fight against Portgas D. Ace. In this attack, Blackbeard uses his devil fruit to cover the entire ground with darkness. The gravity within the darkness crushes everything it consumes, and there is no known way of getting out of it.
4 Shima Yurashi
Known as the Strongest Man in the World, and Whitebeard was feared throughout the world because of his highly potent devil fruit. He possessed the Gura Gura no Mi, which is a paramecia type devil fruit, and it allows its user to create quakes.
In the case of this particular attack, Whitebeard used his superhuman strength to create powerful quakes that can split the sea. It is fair to say that fighting against Whitebeard on the sea was an incredibly foolish decision as one of these tremors could easily take down a multitude of ships.
3 Togen Totsuka
Oden's swordsmanship was on a completely different level in comparison to the samurai of Wano. He is among the best swordsmen in the entire series. Togen Totsuka was Kozuki Oden's strongest technique. He was seen using this attack against Kaido, one of the strongest pirates in One Piece.
Togen Totsuka made use of both of Oden's swords and his Ryou. This attack was powerful enough to pierce Kaido's nigh impregnable skin and it left a huge scar on his body.
2 Hakai
Hakai is a combination attack of two of the Yonko. In this attack, Big Mom uses her homie— Napoleon and Kaido use his kanabo. The sheer size of this combination attack dwarfed the island of Onigashima.
Hakai obliterates anything in its path and it is nigh impossible to stop it. Zoro jumped in front of this attack and ended up suffering several injuries in the process.
1 Whitebeard Roger Haki Clash
Whitebeard and Roger were two of the strongest pirates that ever roamed the seas. The two were fierce rivals but had a lot of respect for each other. For a long time, the true power of these legendary characters was a mystery.
However, it was finally unraveled during the Wano Country arc. During a flashback, it was revealed that the two icons clashed on an island and their attacks were imbued with Advanced Armament and Conqueror's Haki. The attacks were so powerful that their weapons didn't even collide, however, the shockwaves emanating from the clash destroyed the nearby surroundings.
