Having witnessed mountains shift, oceans seethe, and entire nations vanish, I find myself captivated when a new technique is whispered in the One Piece universe.Power in this world transcends mere explosions; it blends willpower, rich history, and narrative weight into a single, formidable strike.
In evaluating strength, I consider several factors: historical feats (such as the devastation of an emperor), the impact on the landscape, and the emotional resonance of pivotal moments (how fans react when pivotal events unfold).The following seven abilities dominate these criteria, leaving me pondering how the next adversary might endure the onslaught.
7 Meigo (Dark Hound) – Sakazuki (Akainu)
Magma That Melts Legends

A fiery claw of magma pierces Whitebeard’s body, scorching half of his face into liquid.With the Magu Magu no Mi in hand, Akainu exhibits the “highest offensive power, ” and Meigo serves as a testament to this claim.
This strike cleaves through even the most resilient flesh, radiating a heat that surpasses all prior agony and relentlessly carves away at legacy itself (the pain of Ace’s demise lingers).
Whereas others may alter the landscape, Meigo obliterates opponents outright; its legacy is etched into the fears and traumas of both characters and readers alike.
6 Galaxy Impact – Monkey D. Garp
Grandpa’s Haymaker, Town-Buster Edition

While aware that Garp could punch cannonballs, witnessing him leap from a battleship to crater Hachinosu was electrifying.Upon impact, his fist creates a Haki explosion, dispersing buildings like leaves caught in a storm.
He jestingly attributes it to rusting muscles, asserting that the prime version of himself could have annihilated the island. I believe him; even from my reading nook, the shockwave felt monumental.His might arises not from a Devil Fruit but from decades of rigorous training combined with Conqueror’s Haki more potent than any metal.
Galaxy Impact exemplifies how sheer will can replicate the force of natural catastrophes, serving as a reminder to young marines that the legends of the past still command respect on the sea.
5 Kamusari (Divine Departure) – Shanks
A Sword Stroke That Ends Futures

With no Devil Fruit in sight, Shanks steps forward, unleashing Conqueror’s Haki so dense it splits the horizon. In an instant, Kid’s railgun dissolves, his ship shatters, and ambitions worth billions vanish as quickly as my coffee cools.
The swing is more of a shockwave than a mere cut—it’s a legacy honed from Roger’s teachings, refined in silence.One decisive movement can influence a battle long before it truly begins, sparing readers the prolonged struggle of lesser conflicts.
What chills me is the purity of it all: steadfast will, impeccable timing, and no wasted energy. When Shanks draws Gryphon, destinies are sealed.
4.Shima Yurashi / Gekishin – Edward “Whitebeard” Newgate
Earthquakes Held in One Hand

Whitebeard raises his fist, reality itself seems to crack, and the battlefield of Marineford tilts ominously.Watching giants falter and tsunamis surge skyward was a spectacle triggered by a single swing. Shima Yurashi shifts tectonic plates with the ease of someone clearing their throat.
When focused into Gekishin, his tremors rip apart admiral armor, serving as a stark reminder of why Sengoku deemed him world-ending.No advanced technology or mythical Zoan abilities—just raw Paramecia power amplified by an indomitable will.
Even when weakened, his punches can reshape coastlines; at full health, one could only imagine the upheaval.
3 Flaming Drum Dragon Shoryu: Kaen Hakke – Kaido
Heat Meant to Vaporise Hope

As Kaido transforms into a living furnace, his scales radiate burning heat with the intent of reducing Luffy’s dreams to ash.The air howls as his dragon maw exhales flames hot enough to melt stone before impact. Even fishermen far from the battleground would feel the rapid temperature rise.
He channels Conqueror’s Haki through that fiery breath, aiming to vaporize with an island-sized punch, illustrating why he is known as the world’s strongest creature. For a fleeting moment, the entire battlefield is blinded by the clash of their powers.
The fact that it ultimately fails only accentuates its dread; had Luffy flinched, Wano could have been reduced to mere glass.
2 Gomu Gomu no Bajrang Gun – Monkey D. Luffy
An Island-Sized Fist of Freedom

As Gear 5 activates, Luffy’s exuberance mirrors my own; the sky over Wano is filled with a fist larger than Onigashima.Pumped with Armament and overflowing with Conqueror’s Haki, he joyfully defies the laws of physics. Watching that fist descend felt like witnessing a sunrise amidst storm clouds.
Kaido responds with fiery dragons, hot enough to melt steel, yet Luffy’s punch drives him into the earth.In one glorious moment, Luffy liberates a nation, crowns a new emperor, and demonstrates that hope triumphs over tyranny, an achievement no statistic can encapsulate.
From now on, every future antagonist must measure their plans against a joyful giant who transforms happiness into weaponry, and I eagerly await their reactions.
1 Lulusia Obliteration – Imu
One Command, One Kingdom Gone

The sky darkens, illuminations pierce through the clouds, and Lulusia simply ceases to be.No countdown, no confrontation, just a silent decree from the throne room that erases land and history alike. My stomach lurched as the world trembled, the ocean level rising significantly while the World Government feigned ignorance.
This act merges the Mother Flame with the ancient weapon Uranus, channeling such immense power that it creates a void in the ocean bed. Each time I revisit that panel, I search for any sign of effort, sweat, or struggle, yet none exists.
When devastation is delivered as a mere signature on clandestine paperwork, I come to realize that every pirate’s dream now hinges on bargaining with a deity who wields a finger poised to erase history.
