Gear Second ignited. Luffy's skin took on a faint reddish hue as his blood pumped at superhuman speed, the steam rising from his body in visible waves. To Vegeta's scouter, the power level was no longer just fluctuating; it was climbing. 2,500... 3,000... 3,500.
"A battle power that rises?" Vegeta's sneer became a grin of pure, sadistic pleasure. "Maybe you aren't completely worthless after all. Let's see how high it goes!"
Luffy vanished, a red blur against the grey landscape. Jet Pistol! His fist, moving faster than the eye could track, slammed into Vegeta's guard. This time, it didn't just bounce off. The force of the blow was enough to crack the Ki barrier and send Vegeta skidding back a few feet.
Vegeta's eyes widened in surprise for a fraction of a second. "Tch!" He retaliated with a blast of yellow Ki from his palm. Luffy, in Gear Second, was a master of evasion. He twisted and spun, his rubber body contorting in impossible ways to let the blasts fly past him.
The fight erupted across the plain. It was a blur of red and gold. Luffy's attacks were wild, unpredictable, and fast. Jet Stamp! Jet Bazooka! Vegeta, however, was a prodigy. Every hit Luffy landed was met with a harder counter. A knee to the gut sent Luffy flying. A blast to the chest scorched his vest.
But Luffy kept getting up. He always got up. His grin, though bloodied, never faded. He was having the time of his life.
Vegeta, however, was growing annoyed. The boy's power wasn't just rising; it was adapting. He was learning to read Vegeta's movements mid-fight. It was a talent that only the greatest of warriors possessed.
"Enough of this!" Vegeta roared. He raised a hand, two fingers to his forehead. "You're annoying me, freak! Let's see you dodge this!" A massive sphere of pure, concentrated energy began to form above his head, crackling with destructive potential. The light it cast was blinding, the pressure immense. It was an attack meant to erase an entire city. An attack meant to erase Luffy.
Luffy felt it. His body screamed at him to move, but his legs were tired. Gear Second was wearing him out. He watched the ball of death form, and for the first time since arriving, he felt a genuine pang of fear. Not for himself, but for the promise he made. He couldn't die here. Not before seeing his crew again.
Think. What would Gramps say? What would Rayleigh say?
A whisper. Not a sound, but a feeling. A cool, calm sensation at the back of his mind, like the moment before unleashing a massive attack. It wasn't his Devil Fruit. It wasn't his physical body. It was... the tingly feeling he'd felt since he arrived. The Ki Roshi had tried to teach him about.
He stopped thinking. He stopped panicking. He just... reached for it. He focused on the feeling of his own life, his own indomitable will, and pushed it forward. He cupped his hands at his hip, just as Roshi had shown him.
Vegeta, focusing on his attack, barely noticed. "Say goodbye! FINAL FLASH!"
At the same moment, Luffy yelled. It wasn't a shout of desperation, but of discovery. A torrent of energy, not blue, but a vibrant, sunburst gold, erupted from his palms. It wasn't refined or controlled. It was a messy, wild blast, a perfect reflection of the boy himself.
The two attacks met in the center of the plain. For a moment, they struggled for dominance. Then, Luffy's gold energy began to push back the purple Final Flash. Vegeta's eyes went wide with shock. "IMPOSSIBLE!"
The golden blast overpowered the Final Flash, shooting past a stunned Vegeta and carving a massive trench into the mountains behind him. It was wild, uncontrolled, and completely drained Luffy of all his remaining strength. He fell to his knees, panting.
Vegeta stood frozen, his scouter shattered, his pride wounded more than his body. "You... you're not just a mutant. You're something else entirely." He turned, his face a mask of fury and intrigue. He leapt into his space pod. "This isn't over, freak! I'll be back! And when I do, I'll figure out what makes you tick!"
The pod shot into the sky and vanished.
Luffy tried to stand, but his legs gave out. He fell onto his back, staring at the sky. A huge smile spread across his face. "Shishishi... I did it... I did the thing..."
He passed out, the golden energy fading from his body, leaving behind only the faintest whisper of its presence. And as he slept, the whisper in his mind returned. It wasn't a voice, but a void, a cold and empty place that was somehow... curious. It had felt the anomaly. It had felt the eruption of a foreign power in a universe bound by its own rules. And it was hungry.
