One Piece: The Multiverse Simulator

It wasn't surprising that everyone was shocked. The revelation that the Pirate King's bloodline had survived to the present day was as earth-shattering as the war between the Navy and the Whitebeard Pirates.

"My father is Whitebeard, not the son of some Pirate King Roger!"

Hearing Sengoku's explosive revelation, Ace was far beyond just shocked—he was utterly unable to accept it.

Ace had long known about his lineage, but he had always rejected it, harboring a deep loathing for his biological father. It wasn't until he ventured to sea, lost to Whitebeard, and was moved by his magnanimity, that Ace accepted Whitebeard as his father and joined the Whitebeard Pirates.

Now, as he stood on the execution platform, this truth he had tried so hard to deny and keep secret was exposed for the world to hear. How could he possibly accept it?

"This is the truth. Your mother, Portgas D. Rouge, protected you from the Navy's pursuit by carrying you in her womb for twenty months, only to die from exhaustion after giving birth to you.

As for the investigation, a certain Navy officer couldn't bear to see an innocent baby killed and chose to protect you…"

As Sengoku spoke, his eyes swept subtly toward Garp.

"Grandpa… did you tell them?"

Ace turned toward Garp, the man who had raised him and later let him roam freely. Though Garp avoided his gaze, his guilt was evident. While Garp hadn't revealed the secret, his inability to save Ace now weighed heavily on him.

Garp had intended to take this secret to his grave. He had hoped Ace would grow up to fulfill his dream of becoming a distinguished Marine. But fate had other plans. Both Luffy and Ace had become pirates, with Ace even rising to become a key figure in the Whitebeard Pirates.

Now, Garp had to watch his grandson face execution, and the pain and regret in his heart were immeasurable.

"I see… but I will never acknowledge that man as my father. From beginning to end, my only father is Whitebeard!"

Ace's defiant cry echoed across the plaza. Suddenly, the calm sea erupted with activity. With waves surging high, the Whitebeard Pirates' flagship, the Moby Dick, surfaced dramatically.

The Whitebeard Pirates had anticipated heavy resistance from the Navy before they could land. Before setting out, they had coated their ships at Sabaody Archipelago and used the propulsion capabilities of the coated vessels to travel underwater.

Now, surfacing so close to Marineford, the Navy's reaction would be too late.

"Well said, Ace! Dad is your true father, and we are your brothers. Hold tight—we're coming to save you!"

"Ace, we're on our way!"

As the Moby Dick emerged, the voices of Whitebeard's crew rang loud and clear. Among them stood a towering figure, 6.66 meters tall, with a crescent-shaped white mustache. Whitebeard himself laughed with his iconic "Gurarararara" and declared:

"Marineford, huh? Not a bad place for a final battle.

Ace, don't worry. As my son, I won't let you die here. Whether or not you're Roger's son, you are my proud son!"

While the Whitebeard Pirates were sharing this heartfelt moment, the Navy couldn't tolerate it any longer. Several commanders quickly ordered their troops to bombard the Moby Dick.

Though the ship had surfaced close to Marineford, it was still at a distance. If the Navy could sink the ship, most of the Devil Fruit users aboard would lose their combat capabilities.

On command, a barrage of cannon fire rained down like a violent storm, covering the sea around the Moby Dick.

With Marineford as their home ground, the Navy had no shortage of artillery or ammunition. The bombardment left no part of the sea uncovered, ensuring a devastating strike.

But the man known as the Strongest Man in the World took matters into his own hands.

Whitebeard tore off the IV drip attached to his arm and gripped his supreme-grade blade, Murakumogiri, tightly with both hands.

A translucent white orb of energy formed at the blade's edge as Whitebeard swung his weapon. The air before him shattered, forming massive spiderweb-like cracks in space.

The moment the space fractured, a powerful shockwave erupted. The cannonballs hanging in midair froze momentarily, suspended in time, before being obliterated into dust by the overwhelming force.

The shockwave didn't stop there—it surged across the sea and slammed into Marineford, sending countless Navy soldiers flying.

"Children, charge forward! I'll cover you. Let's bring Ace home together!"

At Whitebeard's command, dozens of pirate ships emerged from the mist behind the Moby Dick. These ships belonged to Whitebeard's allied forces, loyal affiliates from across the New World.

The Whitebeard Pirates boasted 1,617 members, divided into 16 divisions, each led by a formidable captain. Beyond this, they commanded the allegiance of 43 allied pirate crews, all renowned names across the Grand Line.

Now, the full might of the Whitebeard Pirates had descended upon Marineford, and the stage was set for the most significant battle the world had ever seen.

With each affiliated pirate crew estimated at around one hundred members, Whitebeard's allies alone numbered nearly five thousand. Combined with the Whitebeard Pirates themselves, their forces totaled six to seven thousand strong.

And these weren't just ordinary pirates. To become part of a Four Emperors' faction, one needed a bounty of at least tens of millions of berries. Among Whitebeard's captains, many could rival the Seven Warlords of the Sea in strength.

Facing this unparalleled pirate force, it was understandable that the Navy Headquarters treated the Whitebeard Pirates with such caution.

Before the Navy could initiate a second round of bombardment, Whitebeard placed his supreme-grade blade, Murakumogiri, to the side and stretched his hands outward as if tearing the air.

In the next moment, the seemingly empty air folded and creased under his immense strength, like fabric being pulled. Under the stunned gazes of all, the entire sea around Marineford heaved upward!

A towering tsunami, hundreds of meters high, rose and surged toward Marineford with an overwhelming force, blotting out the sky.

The scale of this tsunami was such that, if left unchecked, it would completely engulf and destroy Marineford.

"This is the power of the world's strongest man? I heard Whitebeard's combat abilities had declined with age.

But seeing this… he could still crush a Navy admiral with ease."

Disguised as Navy grunts, Wood and Russ stood among the marine ranks. As Wood gazed at the colossal tsunami threatening to fall, he couldn't help but marvel at Whitebeard's well-deserved title as the Strongest Man in the World.

At seventy-two, Whitebeard's age wasn't particularly high by the standards of One Piece's superhuman world. His deteriorating health was largely due to the side effects of his Tremor-Tremor Fruit.

Some powerful Devil Fruits often came with physical drawbacks. For instance, Magellan's Venom-Venom Fruit left him spending half his time on the toilet. Similarly, Whitebeard's Tremor-Tremor Fruit put immense strain on his body every time he used it.

Unlike Logia users who could transform their bodies into elements, Paramecia users like Whitebeard didn't have the ability to alter the fundamental structure of their vital organs. While his fruit gave him destructive powers, his heart and other organs remained vulnerable.

Over years of use, each quake inflicted micro-injuries to his internal organs. These cumulative effects, combined with aging, had taken a toll on his body. (Author's speculation—don't come for me!)

The massive tsunami loomed over Marineford, casting a dark shadow over the entire island. Marines stood frozen in terror, their faces etched with fear.

At this critical moment, one of the three admirals—Kuzan (Aokiji)—leaped high into the air. His black curls fluttered as icy energy radiated from his body.

"Ice Age!"

With his arms outstretched, now transformed into massive ice limbs, Aokiji released two streams of frost from his hands. These beams shot out toward the approaching tsunami, spreading at an astonishing speed.

As the air grew chillingly cold, the towering tsunami froze in place, halted mid-crash. The entire wave solidified into an icy wall, its expanse stretching back to where the Moby Dick and its allies lay.

"The old man's sea quake was stopped just like that!"

"The ocean… it's completely frozen! Is this the power of the Navy's admirals?"

The pirates aboard the Whitebeard fleet were stunned into silence. Moments ago, they were terrified of the impending tsunami. Now, they faced a frozen seascape stretching before them.

"Don't be afraid! Facing admirals was expected. We still have to save Ace!"

"That's right! What's a Navy admiral compared to Dad? Charge with me!"

As Whitebeard's men regained their resolve, they leaped from their ships, running across the icy surface toward Marineford.

The Whitebeard Pirates were no strangers to great battles. Despite Aokiji's impressive display, they wouldn't cower. The frozen sea even worked to their advantage, allowing them to advance directly.

"Prepare for combat! Do not let the pirates near the execution platform!"

As the pirates charged, the marines countered with all their might. The clash was immediate, chaotic, and brutal.

"Captain, what's the plan? Do we side with the Navy or the Whitebeard Pirates?"

Russ, holding two defeated pirates in his hands, casually tossed them aside as he turned to Wood for guidance.

Though they had agreed to aid the Navy in secret, Russ knew of Wood's friendly ties with Whitebeard's crew. He also knew his captain was not one to stick to the rules.

"Isn't it obvious? We're chaotic-neutral. Who cares about Navy or pirates? Do whatever you like.

Help the Navy if you want, or aid the pirates if that's your style. I'm heading over there to check things out."

Before Russ could respond, Wood had already disappeared.

Meanwhile, Perona, always one to act independently, had snuck off to find her former captain, Gecko Moria. Despite working for Wood's weapons company under Robin's influence, Perona felt indebted to Moria.

Now, armed with shocking information from Wood, she hoped to warn Moria and prevent him from meeting his end here.
