"That's one way I can kill you. You can't nullify anything if your abilities don't have the concept of time," Billy said, watching Kaido hang motionless in the air. The massive dragon's form was locked mid-roar, his expression frozen in place. The air around him didn't move, and even the faint sparks from his Haki had stopped.
Haki was powerful and all, but without the mind having the concept of time, or even having the concept of time, what would it do? Time itself has moved away from Kaido, allowing Billy's snaps to affect Kaido without actually touching Kaido.
Billy studied him for a moment longer, then snapped his finger again, undoing the pause and returning everything to motion.
With that one snap, Kaido regained his movement, his eyes wide as he looked down at Billy. But before he could attack, Billy snapped again, and Kaido froze once more. This time, his eyes flickered in confusion, his mind blank. He had forgotten what Haki even was, standing there without the memory or understanding of how to use it.
"That's the second way I can kill you," Billy said as he snapped his finger once more. The memory was a complex thing; just because you had strong Haki, it didn't mean much if, with a snap, and before you could focus your Haki to protect your mind, everything you knew was erased.
Kaido blinked in confusion, and the moment the sound reached him, his memories returned. The knowledge of Haki flowed back into him like a flood, and his aura surged to life again. He growled, ready to attack, but before he could move, his body began to change. The dragon scales faded, his strength drained away, and his form shrank until he stood on the ground in his human state once more.
Kaido stumbled slightly, looking down at his hands in shock. The power that had always been a part of him—his Haki, his strength, everything he had gained since his youth—was gone. He could feel it clearly. The years of growth and battle had been stripped away, leaving him as weak as the day he first began his journey.
"This is the 3rd way I can defeat you," Billy said, his tone calm as he watched Kaido struggle to comprehend what had happened. "What I did was revert you back to your origin point. You can't undo something when you've yet to have the power to undo it."
He lifted his hand slightly, revealing the Devil Fruit resting in his palm. Kaido's eyes widened in shock at the sight, his mind trying to process how his fruit had been taken so easily.
Billy snapped his finger again, and Kaido's body changed instantly. His strength returned, his muscles filled out, and his aura roared back to life. He was restored to his prime, yet the Devil Fruit didn't return. He clenched his fists and tried to summon its power, but nothing happened.
Kaido instantly tried to nullify everything, forcing his Haki to explode outward in every direction. The air cracked from the pressure, and the ground beneath him began to splinter. Yet no matter how hard he pushed, the Devil Fruit's power didn't return. His roar shook the island, echoing through the air, but it was useless. The energy he poured into it faded away like smoke, leaving him standing there, breathing heavily, his face filled with shock.
"Oh? Looks like the nullifying ability has its limit," Billy said quietly, watching Kaido's failed attempt. He lifted his hand and snapped his finger again, and at once, his stomach tightened in hunger. The drain on his body hit him hard, the price of using his power catching up fast. Before Kaido could react, a second Kaido appeared beside Billy, identical in every way, his grin matching the original's perfectly.
"4th, I can just recreate you," Billy said as the second Kaido stepped forward, his massive form identical to the original. The copy's grin matched Kaido's perfectly, the same wild energy burning behind its eyes.
Kaido's expression darkened, and without hesitation, he unleashed his Conqueror's Haki, trying to erase the clone completely. But the recreated Kaido didn't back down. His own Conqueror's Haki surged outward, clashing against the original's with equal strength, their auras locking in a violent struggle that shook the skull beneath them.
The two instantly began fighting while Billy ate a meal he had snapped into existence. He sat there calmly, watching the clash unfold before him. The sound of their strikes echoed across the island, each impact shaking the ground and scattering chunks of debris into the air.
The power between the two Kaidos was terrifying; each blow was strong enough to destroy a mountain. Billy continued eating without concern, only glancing up now and then as the battle raged on.
It didn't take long for the fight to reach its end. The recreated Kaido gave it his all, but the difference between them was clear. He lacked the raw power the original Kaido held. After a final, earth-shaking exchange, the copy was sent crashing to the ground, his form breaking apart as the original stood victorious once more. Billy didn't look surprised; he had expected that outcome from the start.
Billy calmly stood up as the remains of the recreated Kaido faded away. He paid no attention to the destruction around him, focusing instead on the original Kaido, who was still towering above with his weapon raised high.
He was covered in injuries, just because the clone was weaker, thanks to the fact Billy didn't have enough energy to perfectly recreate Kaido, it didn't mean Kaido had an easy win.
Kaido's roar shook the air as he came down with everything he had left, his attack filled with rage and exhaustion. Billy looked up, his face calm, and snapped his finger just before the strike landed.
"5th, I can just do this. I wish I won," Billy said. The moment the words left his mouth, everything froze for a single instant. Then, the world glitched. The overwhelming force from Kaido vanished, replaced by silence. When the world returned to normal, Kaido was on his knees, his massive body battered and bruised, blood running down his arm as he struggled to breathe. His Haki was too weak to be used, his strength completely drained. It was over—Kaido had been defeated.
Kaido shook his head, struggling to keep his eyes open. His vision blurred as he tried to steady his breathing, his body refusing to move.
He looked toward Billy, and for a moment, his mind drifted somewhere far away—to the past, to the day of God Valley. Memories long buried began to surface, faint at first, then clear enough for him to see the faces he had once stood beside.
He remembered the battle against Imu, the desperate alliance that had formed to bring the ruler of the world to their knees. Among those who fought that day was a man in a white suit, using powers exactly like the ones Billy now wielded. How could he have forgotten? That's right, Imu had hit him hard across the face, knocking him out and causing him to forget.
Small Flash Back
"So this is the ruler of the world," Kaido said in his dragon form, his voice rumbling across the battlefield. He stood alongside Rocks and Big Mom, the two radiating power that made the air feel heavy.
Floating beside Big Mom were Zeus and Prometheus, their glowing forms circling her like loyal guardians. Not far from them stood Whitebeard, his massive figure impossible to miss. He had followed Rocks here without hesitation, prepared to face death if it meant standing beside his captain one last time. But they weren't the only ones who had come.
Across from them stood Roger and Garp, two men who had once been enemies but now stood together for the same cause. The battlefield was filled with the strongest beings the world had ever seen, gathered for a single purpose—to face Imu.
The tension in the air was unbearable; every breath was weighed down by the power surrounding them. Then, before anyone could move, a sharp snap echoed across the field. From nowhere, Billy appeared, his figure floating down from above them as he joined their ranks.
"Don't mind if I join you guys. I'm from the future — here to erase this piece of shit from this world," Billy said with a light smile, pushing his glasses up with one hand.
"The future?" Rocks asked, one brow lifting as he looked Billy over, curiosity and suspicion mixing in his tone.
"Yeah. Sucks, but you would most likely die today. But let's try and change that, right?" Billy replied with a grin, glancing aside just in time to avoid Big Mom's massive hand as she lunged to grab him.
"You brat! You forgot your promise—or is this from before we met?" Big Mom asked, glaring at him with clear irritation.
Billy only shrugged, his expression calm. "Never met you before, but since you claim we met, there's a chance I travel further back in time than this point… but let's ignore that for now, since we've got a bigger matter to deal with," he said with a grin.
Big Mom's glare faded, her eyes narrowing in thought. She quickly shut her mouth, realizing it was better not to say anything that might stop him from going back and forming that promise he made with her back then.
"Enough talking!" Garp roared, his voice echoing as he launched himself forward, heading straight for Imu without hesitation. The ground cracked beneath his feet from the sheer force of his takeoff.
Billy raised his hand toward the sky, his body leaning back as if letting himself fall. "This would mess up the future… but who cares?" he said with a faint smirk before snapping his finger. The moment the sound rang out, reality shattered into a sea of colors….
Flashback End.
"It was you," Kaido said, his voice hoarse but certain, realization settling in as his eyes widened. Billy only looked at him in confusion, clearly having no idea what Kaido meant. Kaido tried to speak again, but the strength left his body before he could say another word. His eyes closed, and he fell forward, unconscious.
"Yeah, it was me who defeated you," Billy said with a light shrug. Completely misunderstanding what Kaido meant by his words.
