When Luo Xing first invented the Fusion Earrings, the very first scenario he imagined was Kaido and Big Mom fusing together.
But when he brought up the idea to his father-in-law Kaido—
Kaido immediately broke out in goosebumps and declared that he would rather die than fuse with Big Mom.
However, as things stood now…
Well, just like the saying went—true fragrance never lies.
Kaido handed one of the earrings to Big Mom and said:
"You know how to use it, right, Linlin? Wear it on the opposite ear. Don't mess it up."
Big Mom snorted as she took the earring.
"Who do you think I am? I'm a woman, you know. When it comes to earrings, I understand them better than you!"
Kaido silently mocked her in his mind.
A woman?
Linlin, maybe you had some charm when you were younger, but now you're just a useless old hag no one would want even if they tried to throw you away!
Of course, Kaido wisely kept those thoughts to himself.
If he said that out loud, Big Mom would definitely try to kill him.
Her temper was more than capable of doing something like that.
And if that happened, not only would they fail to fuse—taking over Whitebeard's territory might become impossible as well.
Seeing that Big Mom had already put on her earring, Kaido followed suit.
Across from them—
Beckman and the other members of the Red Hair Pirates gathered beside Shanks.
Beckman's expression was extremely serious.
"Those are Fusion Earrings. Another outrageous invention by the Fifth Emperor Luo Xing. They're said to merge two people into one and multiply their power."
To the outside world, the Fusion Earrings were still incredibly mysterious.
The only battle people had truly witnessed was during the Dressrosa incident, when Queen and Jack fused together to fight Akainu.
Shanks' voice grew equally heavy.
"Fusing two people into one… Even Bullet's Fusion Fruit couldn't do something like that."
As a former apprentice on Roger's ship, Shanks naturally knew Douglas Bullet.
Bullet's ability allowed him to fuse external objects into himself—but only lifeless things.
Merging two living people into one was something Bullet's Devil Fruit could never accomplish.
Lucky Roux, the large man whose standing in the crew was even higher than sharpshooter Yasopp, lowered the chicken leg in his hand and said:
"What should we do, Captain? If Kaido and Charlotte Linlin really fuse and their strength doubles, we might not be able to stop them."
Kaido and Big Mom were already among the absolute strongest beings in the world.
If the two of them merged and doubled their strength—
There would no longer be anyone in the world capable of defeating them.
Even Pirate King Roger and Hero of the Marines Garp might not be able to beat their fused form.
Although the Red Hair Pirates possessed two Emperor-level fighters—Shanks and Beckman—and the rest of the crew were all extremely powerful…
Facing the fused Kaido and Big Mom still carried the risk of total annihilation.
When Lucky Roux asked Shanks what to do, he was essentially suggesting a retreat.
After all, this was Whitebeard's territory.
There was no need for them to risk their lives fighting to the death for Whitebeard.
Shanks couldn't help but hesitate.
Naturally, he didn't want himself and his crew to die here for nothing.
But if they simply withdrew now—
The largest territory among the Four Emperors—Whitebeard's domain—would fall into the hands of the Beasts Pirates.
Once that happened, the Beasts Pirates' dominance in the New World would become unstoppable.
Shanks had come to intercept Kaido partly to repay the favor Whitebeard had shown by protecting Roger's son.
But the greater reason—
Was that he didn't want to see the Beasts Pirates grow even stronger.
Just imagine it.
If the Beasts Pirates seized Whitebeard's territory and formed an alliance with the Big Mom Pirates—
They would effectively control more than half of the New World.
Without Whitebeard maintaining the balance among the Four Emperors, that equilibrium would completely collapse.
At that point…
Would there still be any place left for the Red Hair Pirates in the New World?
Shanks would rather see Whitebeard's territory fall to someone else—even Blackbeard—than let it be taken by the Beasts Pirates.
After thinking through all of this, Shanks clenched his teeth and said:
"Wait a little longer. If that fused monster truly proves impossible to defeat… we'll retreat then."
Beckman took a deep drag from his cigarette.
He fully understood Shanks' concerns. Whitebeard's territory absolutely couldn't be handed over to the Beasts Pirates so easily.
Otherwise, the Red Hair Pirates' situation in the New World would become extremely difficult.
After finishing his cigarette, Beckman tossed it aside. His expression turned completely serious.
"Stay focused. Don't let your guard down for even a moment. Let's see what kind of move Kaido and Big Mom are about to unleash."
The Red Hair Pirates watched the two Emperors closely.
Then—
After both Kaido and Big Mom placed the earrings on their ears—
Their bodies began to move toward each other automatically.
Kaido stood over seven meters tall.
Big Mom was even a meter taller than him.
The moment the fusion began—
Their bodies expanded dramatically, swelling to nearly twenty meters in height.
Big Mom's body was bulky.
Kaido's was powerful and muscular.
The nearly twenty-meter fusion giant was primarily based on Kaido's hybrid dragon form, though its skin color had become slightly lighter.
The lighter tone was naturally Big Mom's influence, indicating that the fusion giant had inherited Big Mom's Iron Balloon-like durability.
Additionally—
Flames burned upon the giant's long dragon horns.
Those flames were Big Mom's sun homie—Prometheus.
And beneath its feet floated the thundercloud Zeus.
The fusion giant hovered in the air.
In one hand it held Kaido's kanabo.
In the other, Big Mom's sword Napoleon.
An aura of absolute terror spread from its body.
The moment that aura appeared—
Even the pirates of the Beasts Pirates and the Big Mom Pirates felt their hearts tremble.
Big Mom's children exclaimed:
"So strong! This aura feels like it could destroy the world!"
"Hahaha! Those bastards from the Red Hair Pirates are finished now!"
"Speaking of which, this is all thanks to the invention of that Beasts Pirates' son-in-law. If only that man had married into the Big Mom Pirates instead!"
"Shh! Don't say things like that! Didn't you see what happened last time when Mom mentioned it? Kaido's daughter immediately turned into a raging dragon!"
"Heh, true. That Fifth Emperor Luo Xing must have it rough. With such a fierce dragon-wife at home, he probably doesn't dare even look at other women."
If Luo Xing were present to hear that, he would absolutely protest.
Not only did he think about other women—
His thoughts about them were extremely broad and extremely ambitious.
Queen the Plague glanced disdainfully at Big Mom's children and said to Jack beside him:
"Hmph. Those country bumpkins are making a fuss over something as simple as Fusion Earrings."
But Jack wasn't paying attention to them.
All of his focus was on the fusion giant formed by Kaido and Big Mom.
If the fusion giant he and Queen formed was like a ferocious tiger king—
Then the fusion giant created by Kaido and Big Mom was like an omnipotent divine dragon.
Just in terms of aura alone, the difference was beyond comparison!
Kaido and Big Mom themselves were equally thrilled by the surging power now flowing through their shared body.
Big Mom's consciousness exclaimed:
"So this is fusion? What a strange feeling! It feels like I've ascended to the heavens!"
"Hey, hey, Linlin!"
Kaido's voice echoed.
"Don't use my body while calling yourself 'I' like that!"
Big Mom snapped back:
"You're the one who shouldn't be calling yourself 'I' while using my body!"
Even after fusing into a single being, the two couldn't stop bickering.
Kaido snorted and decided not to argue further.
"The fusion has a time limit. Let's move."
"Use that move from God Valley. You remember it, right, Linlin?"
Big Mom grinned.
"Of course I remember! Back then, if it weren't for our combo attack, we might not have escaped God Valley alive!"
The move they were referring to—
Was their legendary combination attack.
Ocean Sovereignty.
A technique powerful enough to sweep aside any enemy in the world.
But now, in their fused form—
Its power would be even greater.
Even the name Ocean Sovereignty was no longer enough to describe it.
Clang!
With a thunderous sound, the fusion giant crossed the kanabo and Napoleon together.
An unimaginable power gathered between the two weapons.
A torrent of Haki erupted outward, accompanied by terrifying pressure that blanketed the battlefield.
The fusion giant roared like thunder:
"Supreme Conquest · Ocean Overlord!"
The kanabo and Napoleon swung downward toward the Red Hair Pirates.
BOOM!
An indescribably massive shockwave blasted forward.
Wherever it passed—
The land itself split open into a massive channel, and seawater from deep underground surged upward.
The members of the Red Hair Pirates turned pale with shock.
They had expected the fusion giant of Kaido and Big Mom to be powerful—
But they never imagined it would be this overwhelmingly terrifying.
