One Piece Thundergod Marine

"I..."

Seeing this scene, Luffy's heart was filled with unspeakable sorrow.

But he quickly snapped out of it, turning around and sprinting toward the submarine prepared by the Revolutionary Army in the distance.

Sabo knew that Kuma might not get the chance to send Luffy away, so as a backup, he had prepared the submarine.

Although seawater couldn't completely nullify Rowen's lightning-based attacks, thanks to the vast amount of **PYROBROIN** particles contained within, the power of his attacks would be significantly reduced.

Adding in the large number of Fish-Man warriors that had been deployed, even if the submarine capsized, they would still be able to get Luffy to safety.

"Everyone, get to the ship!"

Luffy held back his tears and shouted loudly, extending his arm dozens of meters to grab Zoro, who was lying on the ground.

But then... **zī zī**!

"So... can you tell me why you think you can escape?"

A burst of blue lightning crackled, and in the once-empty space, half of Rowen's body suddenly appeared. His hand formed a blade, and without hesitation, he slashed toward Luffy.

Trying to escape with Rowen's speed? What a naive idea.

Rowen was not like Kizaru, who would let things slide halfway.

As the blade was about to strike, Luffy had no time to stop, but just then, Rowen's lips curled into a smile. The blade of light traced a brilliant arc through the air, vanishing in a flash.

At this point, among the three brothers— Ace, Sabo, and Luffy— Luffy was still not a significant threat. Sabo and Ace, however, were far from weak.

Especially Ace. In the original story, he could go toe-to-toe with Aokiji's **Raving Pheasant Beak** using his **Kyokaen - Mirror Fire Flame**. Now, after awakening the powers of the **Mera-Mera Fruit**, a casual wave of his hand could produce a massive sea of flames capable of melting steel.

Individually, they might still fall short of Kuma, but when Ace and Sabo worked together, they could cause Rowen nearly as much trouble as Kuma.

However, as long as Luffy was there, the two brothers couldn't fully focus on fighting Rowen. They had to protect Luffy, which put them at a disadvantage, as they were essentially walking into a trap.

Just like now...

To save Luffy, Ace charged forward. But instead of Rowen's back, what awaited him was a sharp, menacing blade of light!

"I knew you'd come, Ace..."

Rowen sneered coldly as he swung the blade.

**Thunderbolt Fury: Final Scene!**

**Shhh!!**

Blood splattered everywhere. Ace's eyes rolled back, his body contorting as if struck by a cannonball, limbs flailing, before he was sent flying backward.

A huge, crimson scar stretched across his chest. Through the torn flesh, his trembling internal organs were clearly visible.

"One down..."

After the slash, Rowen crouched down, lightning coursing through his legs. Then, he kicked off the ground with explosive force.

**Soru!**

"Ace!!!"

Seeing this, Sabo's eyes filled with rage as he clutched his injured arm and cried out in agony.

"Two down..."

In an instant, Rowen disappeared into thin air.

His **Soru** could cover a distance of up to 100 meters, during which he moved twice as fast as his lightning transformation and five times faster than his **Blink** technique. While lightning form was useful for aerial combat and long-range attacks, **Blink**, which left no movement trail, was ideal for sudden direction changes and ambushes. But for close-range strikes, **Soru** was more than enough.

**Shhh!**

A clear blade of light sliced through the air, moving too fast for the stunned Sabo to react. He only had time to tense up his muscles before the attack landed.

The result? A one-meter-long gash appeared on his back, cutting deep enough to expose bone. Just like Ace, Sabo was sent flying.

"Tch, the instincts of a pure martial artist, huh!"

If Ace avoided decapitation by sheer luck due to his erratic movement, Sabo had dodged a beheading purely through the combat instincts he had honed from years of martial arts training.

Rowen clicked his tongue in dissatisfaction and vanished once again.

"Three down..."

Luffy, still running, suddenly looked up, only to see Rowen standing ahead of him, holding his lightning blade with one hand and casually slashing through the air.

**Shhh!**

To an outsider, it looked as though Rowen didn't even glance at Luffy, simply mimicking the action of hailing a taxi. In the next moment, however, Luffy, who was running at full speed, crashed into the blade on his own.

**Gūlp...**

With Zoro still in his arms, Luffy tumbled along the edge of the hard granite ground, rolling farther and farther away.

In less than two seconds, Ace, Sabo, and Luffy— all three brothers— had been gravely injured and left on the brink of death!

"You naive little fools!"

After finishing off the three brothers, Rowen lifted his gaze toward the distance.

At the port's edge, soldiers of the Revolutionary Army were locked in battle with Marines led by Henry, trying to protect the submarine and ensure a safe retreat.

Naturally, Henry wasn't going to let that happen. This was G-10. There was no way the Revolutionary Army would be allowed to gain a foothold here.

"Tsk, they're entangled too tightly."

Rowen slightly frowned, the interlocking battle lines shattered his thoughts of wanting to wipe out the enemy with a map cannon.

Though he didn't care about the lives of his subordinates, others couldn't share his optimism.

Rowen didn't want to end up like Akainu, a lonely figure who only looked after his own faction and despised everyone else.

"Hmm? Has it finally begun?"

At that moment, a massive surge of fiery power erupted behind him. Rowen turned around, seemingly enlightened, and looked at the figure enveloped in a blazing white fireball. A smile crept onto his lips.

"Awakening… raging…"

This state didn't have a specific scientific name. Rowen only knew it was something new that appeared when the power of a Devil Fruit suppressed one's humanity.

To use Zephyr's words, in this state, even if some rationality remained, the Ability user was no longer just an Ability user but a "living" Devil Fruit, entirely controlled by the fruit's power.

"Ha… Ha…"

With heavy breaths, the granite floor gradually melted, transforming into bubbling lava. With each step he took, glowing orange footprints were left behind.

In the flames, Ace was slightly hunched over, his arms hanging limply at his sides.

The temperature of the flames entwining around him was frighteningly high, making the entire space tremble slightly. The scorching heat caused air currents to shift, creating rippling waves.

His eyes turned a fiery orange-red, the pupils obscured, as he locked his gaze on Rowen. In the next moment, Ace opened his mouth and roared.

"**Hē ah!!!!**"

Inside his mouth, there was no blood or flesh visible, just the blinding light of a molten furnace.

**Boom!!**

One moment he was still at a distance; the next, Ace was right in front of Rowen.

He shot forward like a cannonball, throwing a punch that collided with Rowen's broad palm.

**Bang…**

From the point of impact, flames surged like dense fog, completely enveloping Rowen in a fountain-like explosion. The shockwave incinerated everything within a hundred meters behind Rowen, turning it to ash.

The seawater instantly vaporized, leaving behind a thick white mist.

Scorching heat rose into the air, with fusion energy continually cascading down. The lightning in the sky began to tremble violently, showing signs of imminent collapse under the high-frequency oscillations.

However, that sign of collapse quickly vanished.

"Not bad! You even remembered to infuse it with Haki…"

Rowen's flesh quickly regenerated, large charred patches of skin being pushed off by newly formed pink muscles beneath, resembling that of an infant.

"But it's still not enough!"

**Kā Chā!**

Gripping Ace's fist tightly, Rowen narrowed his eyes. His empty hand suddenly clenched into a fist and then struck with tremendous force.

**Super Electromagnetic Cannon!**

Using his fists and feet as bullets, Rowen unleashed a powerful punch based on the principles of the **Super Electromagnetic Cannon**, capable of penetrating solid **Tekkai** that was five meters thick.

**Puh!!**

Faced with such a terrifying attack, Ace had no chance to defend himself and was punched right through at point-blank range.

But…

Looking at the flames bursting from the wound, Rowen's gaze sharpened.

"Just as I thought… After completely raging, just like Monet, he has lost his humanity."

Just like Monet, who could be reassembled even after being torn apart by Rowen's **Busoshoku Haki**, Ace had also become something similar. 

However, due to the differing properties of their Devil Fruits, he wasn't like Monet's "Buddhism." Instead, he had fallen into a state of rampant fury.
