"That thing actually didnt take any significant damage!"
In an instant, Whitebeard's face filled with rage as he shouted.
He quickly retreated.
Shiki also had a terrified expression, the hair on his body standing on end as he controlled a huge boulder to block for him, soaring back into the sky.
The next moment, light shone from the Overlord's body.
Like a new sun, it slowly rose into the air.
A powerful aura spreading towards the surrounding, causing everyone present to feel a deep, primal fear.
Several marks were visible on its body from the combined attack, but they quickly healed.
In the blink of an eye, it was back to normal.
"Hiss... what terrifying recovery ability!"
For a moment, gasps of shock could be heard everywhere.
"Damn it, Shiki!" Whitebeard turned his head and shouted fiercely.
"Use our joint attack!"
A joint attack was a technique where two people, in perfect sync, launched a combined assault.
The power of such an attack far exceeded that of two people attacking simultaneously; like Big Mom and Kaido Hakai.
Whitebeard and Shiki exchanged a glance.
"Ready..."
"HAAAAH!"
"Wind Thunder Flame Quake!"
"Buddha Quake!"
Whitebeard took the stance to release his Quake power, a shimmering dome of destructive energy appearing over his fist, mixed with the terrifying energies of wind, thunder, and flame from his dragon form.
As for Shiki, he had already transformed into his Buddha form, generating a massive shockwave of his own.
"GO!" the two roared in unison, releasing the attacks.
Empowered by his Mythical Zoan fruit, Whitebeard's shockwave shot forward at a terrifying speed.
At the same time, Shiki's Shockwave was amplified by the power of his Float-float Fruit, as if an invisible giant hand had suddenly pushed it forward.
The two shockwaves merged, carrying a destructive force that tore through the air with a continuous sonic boom as they shot towards the Overlord.
This was the combined power of two dual-fruit Emperors.
In a flash, the Overlord's body emitted an incredibly dazzling light.
Its hands came together, and endless light and flames converged between them, as if a small sun had been condensed in its palms.
It then launched this stream of light to meet the incoming attack.
The two ultimate techniques collided.
In an instant, the entire world seemed to be torn in half—one side a nearly transparent force of pure vibration, the other a golden light wreathed in stellar flames.
For a moment, they were evenly matched.
Then, both attacks were annihilated, and a wave of pure energy and fire exploded outwards.
The entire planet seemed to tremble.
BOOOOM
"AHHHHH!"
At that moment, whether Marines or pirates, almost no one could stand steady, their faces filled with terror.
Marineford, now completely turned to ruins and was engulfed in complete chaos.
As the wind gradually dissipated, Whitebeard and Shiki were left gasping for breath, their faces pale.
The joint attack had exhausted them.
Nervously, everyone looked towards the Overlord.
It was still standing steadily in place, seemingly undamaged.
When the Marines saw the Overlord was unscathed, screams and cheers erupted.
"Amazing! As expected of Dr. Leon's strongest Seraphim!"
"Hahaha! With a weapon that powerful, Whitebeard is nothing but a weakling in front of it!"
"They're already exhausted! Quick! Kill Whitebeard! Kill all the pirates!"
"Long live Leon! Long live the Overlord!"
"Oh no..." The exhausted Whitebeard's face was extremely grim.
He shook his head with a bitter smile.
"I'm afraid I'll really fall here today."
"Damn it! How can it be so strong?" Shiki gritted his teeth, his eyes showing deep anger and fear.
"Overlord, take down Whitebeard and Shiki," Leon ordered.
Hearing this, the Seraphim turned into a beam of light, flying towards them.
Whitebeard gritted his teeth with a flash of determination in his eyes.
"Shiki! I'll cover you! You take my sons and escape! Quickly!" he roared as he standing up.
His dragon claws tore through space, ripping another deep chasm in the ground, forming a huge ravine between them and the enemy.
"Shiki, what are you still doing?! Get away!"
Hearing Whitebeard's roar, Shiki's face was full of complexity.
"Newgate... be careful!"
With that, he used the last of his strength to float away, grabbing as many of the Whitebeard Pirates as he could.
"MY CHILDREN," Whitebeard roared, turning to face the Overlord alone.
"This is my last order as captain! Take your injured comrades and return to the New World!"
He stood proudly before the abyss, a fierce madness in his eyes, ready to block the enemy alone to leave a hope of survival for his family.
"Pops!" Marco and the others cried out, their faces changing drastically.
They understood his intention.
"Pops, let's go back to the New World together!"
"THIS IS THE CAPTAIN'S ORDER!" Whitebeard roared, his heart anxious.
This was the only way.
"Overlord, let's fight!" Whitebeard shouted, his eyes showing a final blaze of defiance.
The Overlord turned into a stream of light and arrived in front of him.
The half-dragon Whitebeard unleashed the full power of the Tremor-Tremor Fruit.
However, the Overlord's body shone brightly, and a fist wreathed in stellar flames struck out.
The two fists collided.
The Overlord stood steadily in place.
Whitebeard, however, was sent flying like a cannonball, soaring over the huge ravine and landing hard on the other side.
"Cough!"
He coughed up a mouthful of blood, his face pale.
This was the most difficult battle he had ever fought.
There was simply no chance of victory.
"Pops!" Marco and the others quickly rushed over.
"Why aren't you leaving yet!" Whitebeard shouted angrily.
But then he felt his body lighten as Jozu picked him up without a word and ran quickly towards the Moby Dick.
"Everyone, set off!" Marco hurriedly shouted.
However, with a flash of light, the Overlord appeared in front of them, blocking their path.
Whitebeard's custom Seraphim and Weevil fearlessly charged forward to intercept.
But with a mere blur of fists, the Overlord sent all of them flying.
They fell to the ground, sparking with electricity, completely unresponsive.
"You guys leave quickly! I'll hold it back!" Marco shouted, seeing this.
"Marco, we'll help you!" Vista roared, followed by a group of commanders, all charging together.
Their strength was extraordinary, and their teamwork was flawless.
But this time, their enemy was the Overlord.
In the face of its absolute power, numbers and tactics were meaningless.
With the explosion of another small sun, Vista, Marco, and all the other commanders were sent flying, coughing up blood frantically.
"Damn it... Pineapple-Head!" Luffy, who had been escaping, saw this and quickly turned back.
"Gum-Gum Giant Pistol!"
While launching the attack, he also turned invisible.
Transparent giant fists smashed towards the Overlord.
However, the Overlord simply flashed between the endless fist shadows, perfectly avoiding every single attack.
It then extended a single finger, and a beam of light shot towards the empty air.
"AHHH!"
Against its powerful Observation Haki, Luffy's invisibility was useless.
The beam pierced straight through his chest.
"Quick, save him!"
"Stop that Overlord!"
The remaining members of the Whitebeard Pirates charged forward, but it was ultimately futile.
One by one, they were struck down, with almost no power to fight back.
"So strong..."
"I didn't expect the boy to create such a powerful Seraphim. With him, what else do we need?"
"Yeah, we don't even need to take action..."
Sengoku smiled. "It seems that in this war, victory is already without question. We can even completely annihilate the Whitebeard Pirates today! Hahahahaha!"
At this moment, there were almost no pirates left standing.
They had all been knocked down, looking at the Overlord with terrified faces as they tried to crawl away from the terrifying demon.
"Overlord, kill them all," Leon said, a satisfied smile on his face.
The Overlord nodded and was about to step forward.
But at that moment, its aura abruptly dissipated, and it froze in place.
"Eh?" Leon was stunned, then his face became embarrassed.
"Ah... the energy consumption was too great. It's exhausted...again. It seems i still need to make futher improvements."
Seeing this, many pirates of the Whitebeard Pirates reacted, their faces showing surprised as they shouted.
"The Overlord has no energy left! Run!"
With this exclamation, the remaining members of the Whitebeard Pirates scrambled to their feet and rushed towards their ships.
The scene became chaotic.
"Not good! Everyone, capture them!" Sengoku reacted first and hurriedly ordered.
The three Admirals immediately set off, flying over the ravine and rushing towards the Whitebeard Pirates.
"Whitebeard, your life is mine!" Aokiji and Kizaru focused on catching the other members, while Akainu roared and charged directly towards the injured Whitebeard.
(Worry not this was to showcase another leon invention)
