Kaido and Big Mom led their crews in launching wave after wave of attacks.
Bullet and Redfield didn't stand idly by, each unleashing their own powers.
Emperor 1 desperately fired lasers into the fray.
The entire pirate alliance was ganging up on a single Seraphim, which met their assault with its own devastating counterattacks.
"Good opportunity!" Blackbeard, seeing his chance in the chaos, quickly released many of the legendary criminals from their cells.
"Corrupt King" Avalo Pizarro, "Crescent Moon Hunter" Catarina Devon, Shiryu of the Rain... one vicious criminal after another walked free.
"Zehahaha! If you want to escape, then fight Leon with us!" Blackbeard laughed.
He knew Leon's purpose was to stop the Emperors from escaping and freeing more prisoners.
Therefore, to gain their freedom, they had no choice but to strike first and defeat the Overlord.
"Brothers, this is a once-in-a-lifetime opportunity! For freedom, let's go!"
The newly freed prisoners took one look at the situation and spontaneously took action.
"KILL! Defeat Leon and escape Impel Down!"
Suddenly, a massive group of legendary pirates joined the assault.
Seeing this, Kaido and Big Mom were delighted.
Although the Overlord was powerful, they were confident that with so many top-tier fighters joining in, they could finally defeat it and capture Leon.
"Get the boy first!" some of the prisoners from the lower levels shouted, making a direct dash for Leon.
But the Overlord stood like an immovable wall, firmly protecting him.
Behind his guardian, Leon frowned and sneered.
"In that case... Overlord, release your Devil Fruit power!"
As soon as the words fell, raging flames and dazzling light burst forth from the Overlord.
An extremely scorching aura washed over them, so intense that the very air began to distort from the heat.
"What?!!"
Seeing this, Kaido and Big Mom's faces instantly twisted in terror.
Their pupils contracted, and their bodies began to tremble involuntarily.
"So it's... that Devil Fruit ability!" Big Mom's face went pale, and she couldn't help but scream, obviously terrified.
Kaido wore a similar expression, as if he had seen a ghost.
He gritted his teeth, looking at Leon with shock and anger.
"How did you create that devil fruit power?! Impossible!"
Seeing the two Emperors lose their composure, Bullet and Redfield realized something was terribly wrong.
"Kaido! Big Mom! Calm down!" Bullet shouted. "You are both Emperors! What could possibly make you lose your composure like this?"
"You don't understand," Kaido stared intently at the Overlord, his face full of fear.
"This Seraphim... it's using our former captain's Devil Fruit ability!"
Big Mom bit her lip and nodded with a hint of panic in her voice.
"That's right! This is the 'Sun Fruit,' a fruit whose real name the World Government covered up... a fruit so powerful they fear its very existence!" (not luffy fruit)
With these words, Bullet, Redfield and all the surrounding criminals were shocked.
They had never heard of such a fruit.
"The terror and power that even the World Government fears..." Big Mom whispered.
It was too late to say more.
Dazzling light shone from the Overlord's body, as bright as the blazing sun.
Moving at the speed of light, it instantly appeared before them.
With an aura of absolute destruction, it threw a single punch.
BOOM!
Kaido was hit and he violently coughed up blood as he was sent flying backward.
His eyes rolled back, as he was almost passing out instantly.
"KAIDO!"
Seeing this, Big Mom, Bullet, and Redfield were horrified.
They knew that in terms of pure physical defense, Kaido was the strongest among them.
If even he couldn't withstand a single hit...
Before they could react, a flash of light appeared and the Overlord was already in front of them.
'Oh no', was their only thought before lightning-fast fists struck.
BOOM! BOOM! BOOM!
In an instant, Big Mom, Bullet, and Redfield were all sent flying.
They were no match for it at all.
Dozens of the newly freed criminals were obliterated by stray beams of light before they even knew what was happening, their faces frozen in terror.
"Such terrifying power..." Bullet struggled to stand, wiping blood from his mouth.
He watched the Overlord slaughtering the other criminals and felt a terror he hadn't even felt when he faced Gol D. Roger.
"How on earth did you invent such an .... abomination?"
"Kaido!" Redfield shouted, now understanding their earlier panic.
"Does this monster have any weaknesses? How did your Captain Rocks lose back then?"
"Captain Rocks..." Big Mom said, her voice trembling with lingering fear.
"In the battle at God Valley... he was ultimately defeated by Im."
"Im? Who's that?" Redfield frowned.
"Im is the true sovereign of the World Government, the master of the Five Elders," Kaido explained.
"A hidden king who has existed for 800 years."
With these words, all the surrounding prisoners froze in shock.
They had just learned a top-secret truth that the World Government would kill to protect.
"Damn you, Kaido! Why did you say that?!"
"Hurry! Let's team up to defeat this monster and get out of here!"
The remaining prisoners roared and charged at the Overlord.
"Hmph," Leon's brows furrowed. "Overlord. End this."
"Yes."
The Overlord's body began to shine with an extreme light, like a bomb about to detonate.
An aura of absolute annihilation instantly spread out.
'Not good!'
In that instant, all the pirates felt an unparalleled energy rolling towards them.
The next moment, a circle of all-destroying flame and light exploded outward from the Overlord's body, peeling up the very ground layer by layer.
"AHHH!"
The air was filled with shrill screams that were abruptly cut off.
Countless criminals were instantly annihilated upon contact with the light.
Only the top-tier figures like "Evil King" Pizarro and Shiryu of the Rain barely survived.
Most of the executives from the Kaido and Big Mom crews were still standing but were severely injured and bleeding profusely.
"Seraphim, surround them!" Leon ordered.
His Warlord-class guards sprang into action, moving to capture the wounded.
"Damn it!" Katakuri swung his trident, Mogura, desperately resisting.
"Brother, save me!"
Hearing his sister's cry, Katakuri tried to go to her aid, but the Seraphim before him entangled him, giving him no chance to help her.
He could only watch helplessly as his siblings were captured.
In the Beast Pirates' ranks, the Three Disasters desperately fought back.
The recently freed Jack was captured again.
Among the Tobi Roppo, Black Maria, Page One, and Ulti were also taken down.
Among the Sweet Commanders, Smoothie and Snack were killed in the blast.
The two Emperor crews had suffered catastrophic losses.
The scene was completely one-sided.
"No! The enemy is too strong! Retreat immediately!" Kaido roared, his face pale.
"He's right!" Big Mom nodded, trembling.
"If we stay here, we will be anihilated! We have to retreat!"
Bullet and Redfield agreed.
The four of them unleashed terrifying techniques, knocking away the Seraphim that were capturing their subordinates and clearing a path.
"All crews, RETREAT!" Kaido shouted.
"Quickly, Brulee, open the Mirror World!" Big Mom urged.
This had been their escape plan all along; the anywhere door was kept safe within Brulee's dimension.
"Let's run too!" Bullet and Redfield followed the two Emperors.
Blackbeard, seeing the remaining criminals he freed, quickly gathered them and fled behind the main group.
At that moment, every pirate had only one thought: escape.
"Hmph. Still want to go?" A cold glint flashed in Leon's eyes.
"All Seraphim, including the Overlord, open fire. These people are extremely vicious criminals. Show no mercy."
