If Imu was truly the first World Ruler in history, then Davy Jones was the man who came closest to that position before her.
That man not only possessed unparalleled personal strength but also controlled world-destroying biological weapons.
In the world at that time, no one could stop him. In a short period, he enslaved half the world.
Until the first true resistance fighter stood up.
The man named Joy Boy initially sailed out only for his own freedom, but that man seemed to be extraordinary by nature. He repeatedly crushed wave after wave of Davy Jones's subordinate teams sent to capture him.
In a short time, the name Joy Boy echoed throughout the world.
Gradually, he became a banner, a flag of resistance against Davy Jones's tyranny.
According to Joy Boy's own account, during that period, everyone was watching him. He seemed to become the hope for all people enslaved by Davy Jones across the entire world.
Thus, Davy Jones's gaze finally focused on him.
It should be called a crushing defeat.
The fledgling Joy Boy was almost powerless against Davy Jones, who arrived riding a flying dragon. He was almost killed that time.
But just like the protagonist of any legendary story, Joy Boy not only survived the ordeal but also gained stronger power.
He was rescued by the surviving people of Birka.
Although the nation established by the Birkans was destroyed by Davy Jones, the race itself was not annihilated.
They were quietly accumulating strength, seeking revenge against Davy Jones.
And the power Joy Boy possessed was what caught their attention.
The two sides immediately hit it off.
Joy Boy received new power from the Birkans.
It was a fruit with special abilities, called the Gum-Gum Fruit by the Birkans.
Although the Birkan nation was destroyed by Davy Jones, they did not leave empty-handed.
In fact, they not only took a large number of Fruits but also took the Ancient Weapon Uranus with them.
Thus, Joy Boy, who had gained new power, united with the Birkans, who had revived Uranus, and a campaign of revenge against Davy Jones began.
This time, even a powerful figure like Davy Jones could no longer be as arrogant and unchallengeable as before.
Although he still held the upper hand thanks to his unbeatable personal strength, the world realized that even that man could potentially be defeated.
More people rallied around Joy Boy, and one country after another began to join them in fighting Davy Jones.
The most crucial among them was the Giant tribe from Elbaf.
Elbaf was the true name of the original Sun God, the man who saved the world in the previous era. He became the god of Elbaf and was revered by the Giants for generations.
Because of that man's relationship with the Birkans, Elbaf and Birka had a close relationship for generations.
So when Joy Boy and the Birkans officially went to war with Davy Jones, the Giant Kingdom was the first to respond.
The fighting power of the Giants was, of course, vital to the upcoming war, but even more important was the existence of the organization called the Great Hammer Pirates!
It was an organization composed of Giants with extremely outstanding shipbuilding skills.
Because the war was at a stalemate, the Birkans decided to manufacture another weapon comparable to Uranus to completely reverse the situation!
Thus, the Great Hammer Pirates, in the city known as Water Seven, collaborated with a group of human shipwrights to build a ship.
That ship was named Pluto, later known as the Ancient Weapon Pluton!
With one more world-destroying weapon added, plus the legendary Mermaid Princess who joined their ranks thanks to Joy Boy, the balance of power between the two sides had completely reversed.
More crucially, perhaps because the entire world hoped for Joy Boy's victory, the second-generation Sun God was born through the prayers of the masses.
Now, even Davy Jones's proudest personal strength was surpassed by Joy Boy.
Davy Jones was utterly defeated, retreating step by step.
Soon, the whole world was liberated.
The evil kingdom built by Davy Jones was completely destroyed, and the unbeatable Black Dragon was captured by Joy Boy and the others.
Davy Jones, the man who was just one step away from becoming the World Ruler, became a fugitive.
Interestingly, he, who managed to escape by chance, also became a pirate, just like Joy Boy.
But unlike Joy Boy, he was the most infamous pirate.
That man possessed a ship capable of sailing in the deep sea trenches, so even Joy Boy and the Birkans couldn't catch him.
Even though he had been utterly crushed, he still hadn't abandoned his ambition. Even as a pirate, he continued to plunder everywhere unscrupulously.
The game of Davy Back Fight, which is still passed down to the present day, was born during this period.
But no matter how much Davy Jones caused trouble, the world truly returned to order.
The various races that had gathered to oppose Davy Jones united as never before. They eventually formed a massive kingdom.
In this country, all races could coexist harmoniously, and the development of science and technology was unimpeded.
Everything seemed to be heading toward a beautiful future.
Until one day, someone who had once followed Joy Boy and fought Davy Jones found Davy Jones.
A fellow named Nerona Imu, driven by a wicked ambition, wanted to collaborate with this legendary deep-sea pirate.
Yes, Imu was actually a follower of Joy Boy in the beginning.
The twenty kings who supposedly founded the World Government also initially united around Joy Boy to fight the evil Davy Jones.
And now, two evil figures united, and the world was about to see new turmoil.
They first deceived Zunesha and the giant robot Emet, who were tasked by Joy Boy to guard the Final Dragon, and re-released the Final Dragon, gaining power capable of rivaling the Ancient Weapons in Joy Boy's hands.
Then, Davy Jones overtly restarted the war against Joy Boy and his allies, while Imu lurked near Joy Boy, waiting for an opportunity.
Due to Imu's sabotage behind the scenes, the war reached a deadlock.
The turning point came when Imu, as if by fate, gained his own ability.
If Nika was an ability born from the prayers of the masses, then Imu's power was a force cultivated by the entanglement of countless malicious thoughts during the war.
The most wicked ability in history completely changed the world's direction.
Davy Jones was betrayed by Imu.
That fellow was controlled by Imu and began to wantonly destroy the world.
Even if I can't win this war, at least the whole world will be buried with me, Davy Jones said.
Joy Boy was once driven to his wit's end.
And the person who then stepped forward to save the world was Imu.
That fellow proudly declared to the world, carrying Davy Jones's head, that he had saved the world. Even the Final Dragon was moved by him and willingly followed him.
Thus, the person named Imu also became a great hero watched by the world.
Joy Boy was originally very happy about this, feeling that he had gained a new comrade.
Imu even became a high-ranking official in that enormous kingdom, becoming one of the leaders of human society.
But soon, something was amiss.
Joy Boy's companions began to inexplicably clash with other nations.
Once or twice was fine, but as the number of incidents increased, contradictions gradually accumulated.
Especially since many of Joy Boy's companions were not human, they were naturally rejected by humans.
Imu was also covertly and overtly guiding public opinion, targeting Joy Boy and his companions.
The world gradually became volatile, and rumors began to circulate that Joy Boy wanted to become the second Davy Jones and conquer the entire world.
Until one time, someone saw one of Joy Boy's companions kill the king of a certain country and destroy that country in the process.
The powder keg was completely ignited.
Joy Boy was determined to protect his companions, while the kings represented by Imu absolutely refused to allow it.
Thus, war erupted again.
In the early stages of this war, Joy Boy actually didn't want to fight Imu and his allies; he only wholeheartedly wanted to explain.
But it was useless. Only the person who wronged you knows how wronged you truly are.
Imu even took the opportunity to seize Uranus from Joy Boy and almost all of the Birkans' precious collection, including a massive number of Ability Fruits, forming an unprecedented army of ability users.
The war situation began to tilt towards Imu's side.
By the time Imu's offensive became too fierce, and Joy Boy was forced to try and resist, everything was too late.
The situation had completely become one-sided, and there was no longer any chance of victory.
It was only at this point that Joy Boy realized who had been behind all the trouble.
But by then, everything was already settled.
Joy Boy could only hide everything, burying the secrets on the Final Island, hoping to pass the mission of changing the world to a successor.
As for himself, he prepared to seek out Imu for a final battle to the death.
It should be said that even at the final moment, Joy Boy's power completely surpassed Imu's. He almost defeated Imu single-handedly.
But it was no use; Imu was truly despicable.
He threatened Joy Boy with the world, saying that if Joy Boy did not surrender, his Ancient Weapons would utterly destroy the world.
With no other choice, Joy Boy died in such an absurd manner.
His companions had long since either died or fled.
The Mermaid Princess, forced back into the deep sea, cursed Imu and all his ability users, damning them to never be able to conquer the sea.
Originally, this so-called curse would have meant nothing, merely the impotent rage of a loser.
But there was no helping it; the Mermaid Princess was the King of all Sea Kings.
When she issued the curse, all the Sea Kings cursed alongside her.
Just as with the birth of the Nika Fruit, the prayers of all beings changed everything.
Thus, all Fruits were cursed by the sea, and all ability users became landlubbers.
It was only after this that the name 'Devil Fruit' truly came into being.
Everything seemed to have settled.
The information left by Joy Boy ended here. The remaining part was likely supplemented by Joy Boy's companions.
But Roa knew that it wasn't over yet.
After Imu thought everything had settled, Queen Lily perceived something was wrong.
She gradually uncovered the entire truth and traveled to Wano Country, helping the ancestors of the Kozuki family deliver the completed Poneglyphs to various parts of the world.
Only then was true hope left for this world.
As for Queen Lily herself—
"Haha!"
Roa gripped his sword with both hands, elemental energy surging on the blade. The blade fiercely clashed with Imu's claws.
The sky and earth continued to rumble from their confrontation.
"How about that, Imu!"
Roa laughed heartily. "Isn't my power even stronger compared to Joy Boy and Davy Jones back then!"
"Shut up!!"
The monster, whose form was somewhat distorted, roared like thunder exploding in the sky.
"Die! Roa!! Just die!!"
The left hand of the Great Devil pushed forward, and several pentagram formations blossomed before her palm. From these formations, a black energy surge suddenly rushed towards Roa.
"Ooh, how fascinating! Is that truly not magic?"
Roa suddenly flicked his long sword forward. The elemental energy coiling around the blade also transformed into a beam of light that shot out.
The two immensely powerful forces collided again, erupting into a colossal black sun that pierced the sky and earth!
"Damn you!!"
The Great Devil gritted her teeth.
Even she had to admit that the Roa before her was already stronger than Joy Boy was back then!
After all, over these eight hundred years, her own power had also grown stronger, yet Roa was still able to fight her to a standstill!
How was this possible!
How could he be this strong?!
The black sun was suddenly pierced through the middle, and Roa flew in on beating wings, "Is this all you have? Imu! Is this all your power!"
"Roa!!"
Imu was at a loss for words, only able to angrily scream Roa's name.
Overwhelming black tentacles shot out from her body, covering Roa like a torrential downpour.
Roa laughed heartily as he swung his sword to block, ensuring not a single tentacle could touch him.
"It seems your limit is just this,"
While parrying Imu's attack, Roa smiled and said, "Only three forms, even counting the possession state. How embarrassing."
"Never mind. Since that's the case, let's end all of this."
Roa curled the corner of his mouth, "Watch closely. Evolution, begins now!"
