15) VENOM DEMON: JIGOKU NO SHINPAN – MAGELLAN
Venom Demon: Jigoku no Shinpan is Magellan‘s ultimate attack. He produces an enormous amount of liquid poison, that he calls Kinjite and, from it, he forms into a massive devil-like entity that mimics his every movement, with its head and hands resemble those of Magellan’s. The color of this poison liquid is crimson-colored and releases a noxious smoke to go along with it. The poison made from Hell’s Judgment is so toxic that it affects even non-organic objects, with the poison spreading like a disease over everything that makes contact with it, even if not directly, and seems to kill the afflicted victims right away once the infection spreads all the way throughout the body (which seems to be at a very rapid rate). Magellan claimed that this technique is potent enough to destroy all of Impel Down.
14) URSUS SHOCK – BARTHOLOMEW KUMA
Kuma gathers air with his palms and compresses it into a giant bubble which resembles a paw-print. Once the bubble is compact enough to fit within his hands, he releases the compressed air and sends it toward his opponent. The air quickly decompresses, causing a massive explosion in the form of a bear paw. The force of this blast was powerful enough to knock out most of Kuma’s targets on Thriller Bark, as well as encompass the entire island and a sizable portion of the ocean. This was also able to cause massive damage to Oars Jr., a giant of abnormal size.
13) SANTORYU OGI: ICHIDAI SANZEN DAISEN SEKAI – RORONOA ZORO
Santoryu Ogi: Ichidai Sanzen Daisen Sekai is an enhanced version of “Sanzen Sekai”. Zoro delivers massive slashes to his opponent one after another. This technique can be done airbone and is capable of cutting through a large amount of solid stone with ease. This was first used against Pica, slashing several times at his giant stone body to lure him out and defeat him with the final slash of the move. When Zoro used this technique he used Haki on his swords to make them more durable and the attack even stronger.
12) GAMMA KNIFE – TRAFALGAR D. LAW
Gamma Knife is Law‘s strongest technique. Law creates a short blade of energy before stabbing his opponent with it. This technique destroys his victim’s internal organs without leaving any external wounds. According to Law, not even someone of Doflamingo’s caliber can survive this. This was first used to fatally wound Doflamingo, though he managed to mitigate the worst of the effects by stitching his damaged organs back together with his string ability.
11) SHISHI ODOSHI: CHIMAKI – “GOLDEN LION” SHIKI
Shiki uses Shishi Odoshi to break open the ground and fashion the debris into the shape of lion heads with which he then uses to attack the enemy.
Shishi Odoshi: Chimaki is a variation on the Shishi Odoshi technique, where the lion heads are part of a wave that crest high over their victims and then break directly over them in a massive whirlpool-styled vortex, burying them in tons of dirt before compacting and shooting upwards in a massive column that rapidly condenses into a gigantic drill-shaped helix that is so solid that it prevents the opponent from moving any part of their body.
10) GOD THREAD – DONQUIXOTE DOFLAMINGO
Doflamingo summons sixteen thick strings which he refers to as “holy ammunition” and sends them at his opponent in a piercing formation. It is possibly a homage to his childhood while he was being tortured as a father cried out that the Celestial Dragons shot his son sixteen times with a pistol; Doflamingo’s cruel way to mock the said father, as well as showing how much he desperately wants to regain his title as a World Noble. This was first used against Luffy at the end of their final fight, but was broken through by his King Kong Gun.
9) YASAKANI NO MAGATAMA – KIZARU
Kizaru crosses his arms in front of him and uses both hands to fire a torrent of deadly light particles, causing extreme damage to whatever they hit. Kizaru can control the spread of the attack, limiting it to a single person or covering an extremely wide area. It also has great piercing properties, penetrating a thick layer of ice and then piercing deep into the water with ease. It was first used against Whitebeard but was blocked by Marco. He used it again with a much wider spread in a failed attempt to strike down the Heart Pirates’ submarine, though the bolts managed to pierce a thick layer of Aokiji’s ice and travel deep into the ocean.
8) ZAN GIRI MOCHI – CHARLOTTE KATAKURI
Katakuri turns his entire body into mochi and rapidly spins towards his opponent in a donut-like shape. When he reaches his opponent he returns to normal shape and, using the momentum from the spinning, slams his enlarged mochi forearm, covered in spikes and hardened with Busoshoku Haki, into his opponent with tremendous force. Aside from the damage caused by the powerful impact, his opponent will also be stuck to his forearm due to the stickiness of the mochi, which Katakuri then uses to swing his arm through the air before smashing it down into the ground, crushing his opponent under its weight with enough force to create a large crater. It was first used against Luffy during their fight in Mirro-World.
7) GOMU GOMU NO KING COBRA – MONKEY D. LUFFY
In his Gear 4 Snakeman form, Luffy compresses his arm, and as he releases it, instead of directly targeting his opponent, he first has his arm loop around himself once before sending his enlarged fist flying at his opponent. The wide loop gives his attack additional acceleration, thus increasing its momentum, while enlarging the fist adds more mass, the combination multiplying the force of this strike. It was first used against Katakuri, successfully knocking him out in a single hit.
6) RAIGO – GOD ENEL
Most of Enel’s attacks are named after thunder gods from various mythologies and religions, fitting his theme as the self-proclaimed “God” of Skypiea.
Raigo is Enel‘s most powerful attack. He combines his own electric powers with the Ark Maxim to create a huge spherical cloud filled with electricity. The ball has enough power to destroy an entire island.
5) ICE AGE – KUZAN
Ice Age is an attack used only near the ocean or another large area of water. Kuzan places his hand in the water, then in an instant freezes it (along with anything in/on it) completely solid. The actual extent of the ice can stretch for miles and last for over a week. This was first seen freezing a massive area of ocean for Tonjit and Shelly to travel through the Long Ring Long Land. Later uses of this attack have demonstrated that Kuzan is not limited to needing to make direct contact with his hands, as the attack can still be conducted as long as the ice he controls is in contact with both himself and the area he wishes to freeze.
4) RYUSEI KAZAN – AKAINU
Ryusei Kazan resembles Dai Funka, but with multiple magma fists rather than just one. Sakazuki points both fists into the air and fires a great number of magma fists upwards in order to let them rain down upon the battlefield, causing enormous amounts of area damage. It resembles a cross between a volcanic eruption and a meteor shower. This was first used to destroy the ice floor that Aokiji created, along with the pirates who were standing on it. It also boiled the seawater, scalding anyone who remained in it. He managed to take out Whitebeard’s flagship, the Moby Dick, with this technique. In the anime, the meteors first fly high into the sky and above the clouds, and then fall back down as if though they truly descended from space.
3) BLACK HOLE – MARSHALL D. TEACH “BLACKBEARD”
Blackbeard spreads his darkness over a large area and, much like an actual black hole, swallows up anything he chooses. When swallowed, the person or object is subjected to a large amount of gravity and crushed, such as an entire village on the island of Banaro. This technique was first seen as it was demonstrated in front of Ace.
2) RAIMEI HAKKE – KAIDO
Raimei Hakke (literal meaning “Thunderclap Eight Trigrams”): Kaido charges towards his opponent at high speed, swinging his kanabo horizontally to strike them with devastating force. It was first used against Luffy in his Gear Fourth form, knocking him unconscious with a single hit!
1) SHIMA YURASHI – EDWARD NEWGATE “WHITEBEARD”
Whitebeard‘s devil fruit is fearsomely reputed to be able to destroy the world and is considered to be the strongest Devil Fruit within the Paramecia class, having powers no weaker than those of a Logia.
None of Whitebeard’s attacks are named in the manga or anime, but they are named in the game One Piece: Gigant Battle.
Using Shima Yurashi, Whitebeard “grabs” an entire area, by grabbing and pulling on the air around him as if it were tangible, and rapidly shifts it. Using this, he tilted the entire island of Marineford and the sea around it, destroying buildings and throwing a giant off of his feet in the process.
