Kane never expected that he had just caught a Rayquaza with a Master Ball in the Ultra Emerald, and in the blink of an eye, he was transported to the world of pirates.

Good news, I have a new devil fruit with a Rayquaza pattern.

Bad news, Kaido, who was doing bungee jumping, landed right next to him.

As a result, the Beasts Pirates gained a natural disaster, and Wano Country gained a guardian dragon.

Many years later.

Robin: "Lord Kane, please make it rain in the order of Hakumai, Suzuho, Hananoto, Nozomi, and Kuri. By the way, please keep the rabbit bowl dry."

Kane: "Damn it, I'm Rayquaza, not Wish Dragon!"

Yamato: "Then Kane, come and fight me for fun!"

Kane: "Ah, the people of Wano Country need me. I'll definitely come back next time."

Kane quickly turned...

Gu Changtian accidentally travels to the world of One Piece and is bound to the One-Punch Man Summoning System. In the One Piece world, he establishes the First Legion and continuously accumulates shock points.

Such a terrifying demon has crossed over into the world of One Piece. What will become of the One Piece world...?

"The Warring States period was terrifying; the First Legion members were all like monsters..."

Whitebeard: "Giants are the strongest men in the world..."

Redhead: "Oh no, my pride isn't working anymore..."

Garp: "Even my iron fist can't beat the First Legion..."

Kizaru: "No matter how much money you offer me, I won't fight the First Army..."

"Only domineering power can rise above everything else."

This is a famous saying by Kaido, the gold-medal lecturer of the Grand Line, known as "King of Beasts," and is regarded as a guiding principle by countless people.

But Roy did not agree with this.

"Then let me ask you—if there were a user who could analyze and collect all the Devil Fruit abilities, and was unaffected by Seastone and seawater, could he reach the pinnacle of this ocean with his Devil Fruit abilities?"

To prove his point, Roy took action.

...

Many years later.

On the Red Line, the sacred site of Mary Geoise is ablaze.

At the top of Pangu City, the instigator stands in the sky.

The pristine white navy cloak fluttered in the wind.

"Do you want to be at odds with the world?"

When confronted with questions from the world's nobles, Roy simply grinned.

"Haven't I already been at odds with the world all along?"

He smiled.

Those who followed him emerged from behind him.

The figures leading the group silenced the entire scene.

Everyone recognized them.

They are all powerful figures who have suddenly risen to fame on the high seas in recent years.

Among them were assassins, revolutionaries, pirates, merchants, doctors...

Without exception, they were all extremely powerful ability users, and they all belonged to the same organization.

Legend has it that the organization has a mysterious leader who is now the most dangerous criminal in the sea.

Now, the facts speak for themselves.

"You, you are..."

A new generation of legends in the Navy.

The most dangerous criminal in the ocean.

They were the same person from the very beginning.

His name is...Loy Amos.

Traveling through the pirate world, he was swallowed by the King of the Sea at the beginning, and then awakened the god-level [Cube Fruit]!

Everything in the world can be decomposed and reassembled! Others work hard to develop fruits, I directly read the data and synthesize it with one click!

While the navy was still showing off their pacifism, my 100-meter Diamond Gundam had already been assembled.

Everyone thought I was adventuring on the Grand Line...

They don’t know that every time I arrive at an island, I copy the data of the entire island!

The Battle of Marineford breaks out, and the eyes of the world are focused on the execution platform...

I printed a "Sky Island" directly above the Navy Headquarters! ?

Liu Yishou accidentally drifted into the world of pirates and obtained a strange pentagram array that could summon characters from another world.

His first partner turned out to be Wolf!

From now on, he will take Gray Wolf and other companions to travel freely in the world of pirates.

Lu Yu accidentally traveled to the world of One Piece and was bound to the God-level Pirate Crew System.

My crew? Yeah... it's a little special.

First Division: Night Raid from the Akame Ga Kill.

Second Division: The Akatsuki, led by Pain, from the Naruto world.

Third Division: The Seven Deadly Sins.

Naval Headquarters:

"Everyone, be on high alert. That man... he's coming."

Four Emperors:

"Sh*t, who the hell provoked him this time?!"

"Someone get ready to apologize. I’ll go in person if I have to...

When Kaido merged with the soul of an unlucky transmigrator, he learned that the world he was in was a manga, and that he was merely a stepping stone for Luffy, the so-called chosen one of destiny, to defeat him.

"What kind of bullshit is Wang Luffy, Chosen One, Joy Boy? I'm going to smash you all to pieces..."

'Ding, system loading...'

Kaido: "So this is the cheat code of that unfortunate transmigrator? It seems that after merging with that guy's memories, I not only know the direction of the plot, but I also have a cheat code to use..."

'Ding, system loading complete. You are not the host of this system. The system will automatically unbind you. Goodbye...'

Kaido: "Damn it..."

(Cheerful, cold-blooded, ruthless, bloodthirsty, ambitious. Kaido is the Kaido from the original work, but one who knows the plot; his personality won't change much.) (Completed novel: "One Piece, Me, Marco, Starting with the Marineford War")

Shako, a seasoned office worker, accidentally died from electrocution while slacking off at work and watching One Piece. His soul was transported to the One Piece world and he was rescued by Whitebeard. He eventually recognized the pirate as his father, changed his name to Shako, and became Edward Newgate's eldest son and the vice-captain of the Whitebeard Pirates.

Shaq: "Hahaha, that old devil Im's era was called Whitebeard!"

Whitebeard: "Gurarararararar, what do I, an old man in my seventies or eighties, know? If you have something to say, go talk to my good-for-nothing son."

Decades after Whitebeard reigned supreme over the seas, people were astonished to discover that this old man showed no signs of aging. Even more terrifying was that if anyone coveted his throne, they would be met with devastating attacks and the whispers of a demon.

"Hahaha, what kind of Tom, Dick, or Harry dares to disrespect my old man?!" (The synopsis is insufficient; please proceed to the main text.)

The protagonist, Dicas, is transported to the world of One Piece and becomes a stray cat. Just when he is lamenting the tragedy and helplessness of life, the strongest cat god system descends. Watch how the protagonist improves his strength, how he uses the system to summon cats from the anime in his memories, and how he leads them to make a name for themselves in the sea world and make a name for their cat clan.

Rainbow Cat: "Let me, Rainbow Cat, the greatest swordsman of the cat clan, learn about the swordsmanship of this world."

Doraemon: "Rainbow Cat, wait a minute, let me get out the Lightning Ball to help you."

Dorami: "Wait a minute, brother, watch me use the shock gun in my left hand and the air cannon in my right to help you."

Meow: "I can do anything except catch Pikachu."

Talking Tom: "Me too. I'm invincible except for catching Jerry."

Star Cat: "Come and experience the charm of martial arts, magic, and wisdom. Here I come."

Abu: "Let's forget about the above. How about I show our enemies what the combination of technology and strength really means?"

Stingy Cat: "Come and experience the power of this Cat King's Explosive Red Fang."

Black Cat Sheriff: "I bet your bullets won't curve."

Blue Cat: "Hehe, do you know why I'm the leader of the Dragon Riders?"

Gatomon: "Let me destroy you in the name of the angels."

Tomorrow's Bright Moon: "We, the cat clan, will remove all obstacles."

Xiaoqing: "Let me tell you what it means to overcome strength with softness?"

Sugar: "Do you know what it means to break through force with speed? It's simple, just let me eat my fill of fish balls."

Whirlwind Claw: "I am the number one constable in the world."

The world of One Piece is silent and shocked.

[One Piece, summon, cool story, system, upgrade, invincible]

Travel through time and become Luffy, and bind to the invincible system.

It is my destiny to aspire to become the Pirate King.

Being targeted by Nami is naturally the benefit of choosing to be the Pirate King.
