At that moment, Kid had already closed in on Bob, aiming his arm directly at him.
"Magnetic Collision!"
As the words fell, the metal fragments scattered in the air seemed to come alive under the pull of a mysterious force, relentlessly surging towards Bob.
Facing the rapidly approaching metal shards, Bob merely smiled faintly.
With a slight tremor, a faint purple aura emanated from his body.
At the same time, Bob stepped on an air current and instantly appeared beside Kid, grabbing him and using him as a shield.
The metal fragments, as if drawn to a delicious meal, relentlessly struck Kid instead.
Within moments, Kid was completely encased in metal, turning into an iron man, while the Mechanical Skeleton beneath him was shredded into scrap by the impossibly fast metal fragments.
With a flick of his wrist, Bob tossed Kid aside.
And as an added "gift" he delivered a kick to Kid's backside.
In the next moment, Kid traced an arc through the air before crashing into the ground, barely alive as he spat blood, hands barely propping himself up.
Though Bob had held back significantly, controlling his strength as much as possible, Kid still couldn't withstand the impact.
"ROOM·Slaughterhouse!!"
Thanks to Luffy's interference, Law managed to seize a brief moment to shout out his attack.
In a flash, Law transformed into a streak of blinding white light, darting across the sky and appearing right beside Bob in the blink of an eye.
"Gamma knife!!"
The moment Law materialized in front of Bob, he vanished again, reappearing behind Law as a bolt of yellow lightning.
In his hand was a blade forged from crackling green electricity.
"Zzzzt!!"
"Let's see if your body can withstand this blade!"
With those words, Law thrust the lightning-clad blade straight toward Bob's back.
"Gone?! How?!"
Law's Gamma knife pierced right through where Bob's spine should have been—yet his hand met no resistance.
Clearly, the Bob before him was nothing but an afterimage.
Just as Law was about to expand his Observation Haki to sense his surroundings—
In an instant.
A terrifying presence locked onto him from behind.
A chill shot up from his feet, freezing him to the core.
Without hesitation, Law's first instinct was to flee.
But it was too late—Bob had already moved.
His hand clamped onto Law's lightning Gamma knife, twisting his wrist downward with an unshakable grip.
No matter how Law struggled, he couldn't break free from the overwhelming force.
"Schlick—"
The sound of flesh being sliced echoed as the knife in Law's own hand plunged into his shoulder, blood spraying from the wound.
Bob then tossed Law aside like a discarded trash.
"Mamamama!"
"These brats can't even take one hit!"
"I havent even started yet and they're already all down!" Big Mom stood atop Prometheus, looking down at the rookie pirates who had been instantly defeated and spoke loudly.
Beside her, Zeus hovered in the air, wearing the same humanized sneer as Prometheus.
"Kaido!"
"Why did Bob personally come here for such small fry?" Big Mom asked Kaido, who stood nearby.
Hearing this, Kaido gripped his kanabo with one hand, his eyes fixed on the darkness ahead.
"The commander must have his reasons!"
"He's clearly holding back against these brats who don't know their limits—giving them enough leeway to fight back!"
Kaido planted his kanabo beside him as he replied.
Even in just these few moments, Bob had already knocked these rookies flat.
But Kaido knew that if Bob had truly gone all out, these so-called "super rookies" wouldn't even have had a chance to lift a finger.
In an instant, they would have become cold corpses.
"The toughest one is getting back up!"
From the darkness Kaido had been watching, Straw Hat Luffy slowly emerged.
His Fourth Gear Bound Man form had been deflated by Bob's earlier strike, reverting him to his base appearance.
Stepping out of the shadows and into the moonlight, Luffy's face beneath his straw hat darkened as he saw his defeated ally scattered across the ground.
The next moment.
A surge of aura erupted from Luffy's body, a purplish-black shockwave instantly sweeping across the battlefield.
His conqueror's haki exploded outward in all directions!!
In an instant.
The rare power possessed by only one in a million flooded the Skull Dome.
Whether it was Kid, Zoro, Law, Killer, or even Big Mom and Kaido— all felt an invisible pressure descend upon the area.
"That Straw Hat Kid's pissed!" Big Mom remarked, her eyes locked on Luffy.
But she wasn't particularly surprised—after all, she possessed the same Haki and hers was even stronger than his.
Meanwhile, Kaido looked at Luffy with a hint of admiration.
Those who wielded Conqueror's Haki were figures who shaped the world's tides.
One could say it was a badge of the world's elite—while not all top-tier fighters had it, those who did were guaranteed to be powerhouses.
"Conqueror's Haki, huh?"
"I can't even remember the last time I used it."
Bob muttered as he observed luffy before him, that invisible pressure radiating outward.
Conqueror's Haki—he hadn't used this power in a long time, not even during the Summit War.
The same went for Armament Haki.
Because at his current level, Armament Haki offered him no meaningful enhancement whatsoever.
"This time, I'll show you what real Haki looks like!" Bob said calmly.
The moment his words fell.
Bob's eyes narrowed slightly.
An overwhelming, domineering aura burst forth from his body—unlike Luffy's reddish-black Conqueror's Haki, Bob's manifested as a transparent, invisible force.
Instantly, this intangible power surged outward in all directions.
The ground shattered under its pressure, rocks flew wildly through the air, and dust and debris filled the battlefield.
The next moment, the domineering aura around Bob rapidly condensed and took form, transforming into an invisible shockwave that shot straight into the sky, scattering all the clouds above.
