More than ten kilometers outside the Flower Capital, on a vast open field.
"BORORORO! We're far enough from the Flower Capital now. This distance should suffice, Straw Hat!"
Caesar stood leisurely on the ground, holding his massive blade Zhu Long.
Before him stood Luffy, Zoro, Kid and Law, lined up in a row.
This scene bore an uncanny resemblance to the decisive battle atop Onigashima just days ago.
The only difference was that after the initial skirmish, it had turned into a one-on-one between Luffy and Kaido.
Covered in blood, Luffy clenched his fists and stepped forward to face Caesar, looking up at him.
"One after another, damn it! Why are there so many old monsters in Wano—no, in the New World? Caesar, do you want to rule this country like Kaido did?"
Caesar grinned. "Rule this country? Boring. I have no interest in that. It's just some backwater nation. Don't compare me to my little brother, Straw Hat."
"Then why don't you leave? Why come back to this place again?" Luffy gritted his teeth.
"Borororo, I told you it's just boredom!" Caesar laughed maniacally, suddenly swinging his massive blade without warning.
"I just woke up and heard some brats playing in the mud had defeated my worthless little brother. That piqued my interest. Sure, Kaido was a fool, but not just anyone could beat him. Straw Hat, did you know? Thirty-eight years ago, I fought your grandfather. Garp back then gave me quite the challenge. I wonder if you're as strong as him back then!"
Clang!
Zoro muscles bulged as he crossed his three swords to block Caesar's blade, his teeth clenched and the ground beneath him cracking under the pressure.
Pale flames erupted around Luffy as his aura surged violently.
Conqueror's Haki!
"Let's find out! Fourth Gear: Muscle Balloon, Bounce Man!"
"Gomu Gomu no... King Kong Gun!"
"ROOM!"
Law instantly activated his ability, a massive spherical dome covering hundreds of meters, teleporting Luffy from in front of Caesar directly above his head!
"This battlefield is a great location. There should be plenty of metal underground." Kid stepped forward on his prosthetic leg made of steel, slamming his massive metal arm into the ground.
"Magnetic Field!"
A tremendous force of attraction erupted from Kid, causing the earth to heave and crack open.
Crack! Crack! Crack!
Rusty weapons and metal objects flew toward Kid right hand like birds returning to their nest, rapidly gathering.
"Magnetic Demon: Skull Giant!"
Countless pieces of metal merged in an instant, forming a towering skeletal warrior with an awe-inspiring presence.
"RAIJIN HAKKE!"
Clang!
Zoro three swords trembled violently, unable to withstand Caesar's monstrous strength any longer.
His body was sent flying hundreds of meters, carving a deep trench into the ground.
"BORORORO! Good! That's the spirit!" Caesar raised his right hand, catching Luffy massive fist as it descended from above.
He clenched his fingers around it and hurled Luffy straight at Kid skeletal warrior.
His towering frame bulged with explosive muscle as he throw a punch.
BOOM!
The earth shattered, countless rocks and debris exploding outward as the terrifying shockwave obliterated everything in its path.
"ROOM! Shambles!" In an instant, Law whisked Kid and Luffy away.
Caesar roared "Law huh, your ability disgusts me! Can't even have a proper fight! Fine then, let's see how long you can keep that up!"
Dropping his massive blade, Caesar clenched his fists as dark energy enveloped his body, forming eerie spiral patterns resembling the surface of a Devil Fruit.
"Hybird Form! Kun-Kun Giant!"
Caesar body became bigger like an inflating balloon, muscles bursting forth in grotesque proportions.
Ten meters.
Fifty meters.
One hundred meters.
Five hundred meters.
"ROAR!"
The heavens and earth trembled as Caesar transformed into a towering black colossus, his two pillar-like arms stretching three hundred meters—comparable to a mountain range.
Like a titan from myth, Caesar bent forward and smashed his fist into the ground!
The impact rivaled a nuclear explosion!
The earth collapsed for kilometers around as his mountain-sized fist carved a bottomless crater into the land.
"Three-Sword Style! Three Thousand Great Thousand Worlds!" Zoro roared, unleashing his Conqueror's Haki at full force.
A black blade light, reaching from earth to sky, tore through space and sliced open Caesar abdomen.
"World-Ending Demon Fist!"
Caesar erupted with fury, his arms becoming blurs as fist after fist—each the size of a hill—pounded the earth.
The entire Flower Capital quaked as if struck by a magnitude-10 earthquake, massive chunks of terrain fracturing and collapsing.
BOOM!
Kid's freshly assembled skeletal giant was punched hundreds of meters underground by Caesar fist.
"How are we supposed to fight this?!" Law stared at the sky-piercing black titan, despair creeping into his heart.
Against this cataclysmic assault, Law could only repeatedly use his ability to teleport their group to safety.
His power drained his stamina rapidly and after such frequent use, Law face turned deathly pale, his body swaying unsteadily.
"Straw Hat-ya! Kid-ya! Everyone—use your power now! I can't hold out much longer! I'll immobilize him! All of you—aim for his vitals!"
"GOT IT!" Luffy and Kid shouted in unison.
BOOM! BOOM! BOOM! BOOM!
Caesar continued his relentless bombardment, his seemingly endless power pouring forth without restraint.
Law took a deep breath and activated the last of his Awakened Devil Fruit energy.
"K-ROOM!"
Channeling every ounce of remaining stamina, he instantly erected a kilometer-wide barrier.
Swinging his blade horizontally, he cleanly severed the ground beneath Caesar's feet, slicing off an entire layer of terrain.
"Flip!" Law roared, flipping his palm.
Caesar massive body lurched sideways, losing balance and the 500-meter-tall giant crashed to the ground with an earth-shaking impact.
Law instantly teleported above Caesar, thrusting his demonic blade downward with all his might!
WHOOSH!
The blade extended infinitely, stretching a kilometer in an instant—pinning Caesar gargantuan form to the earth.
"Pierce! Great Impact!"
Caesar colossal frame convulsed violently as blood erupted all over his body.
His mind grew foggy and his consciousness wavering.
"NOW!" Luffy howled, his right arm stretching and swelling rapidly.
A fist rivaling Caesar's own formed midair, lightning from the skies coiling around it.
Luffy poured every drop of his Haki into the colossal fist, amplifying its power.
"Gomu Gomu no, Bajrang Gun!!"
The colossal fist slammed down!
Caesar head was smashed into the ground, his entire body upended like a headless giant corpse.
Yet the group didn't dare to relax.
Zoro infused all three blades with Supreme Haki Infusion, black-red energy swirling as he leaped high.
"King of Hell Three-Sword Style! Flying Dragon Slash!"
The dazzling sword light shattered space itself, cleaving Caesar from his groin up to his neck.
Blood and chunks of his body sprayed grotesquely across the battlefield.
But it wasn't over yet.
Kid roared as scrap metal formed a rectangular container over ten meters tall behind him - a massive cannon aimed at Caesar's mutilated remains.
Blinding electromagnetic energy gathered at its mouth.
"Railgun!"
The searing electrical blast reduced Caesar massive corpse to charred wreckage, evaporating even the blood midair.
