The battle had dragged on for an indeterminate length of time, yet neither fighter showed the slightest sign of fatigue. On the contrary, their clashes only grew more violent with each exchange.
Kaido, in particular, was completely fired up. He had originally planned to challenge Whitebeard after reclaiming his youth, but Uchiha Madara's strength far surpassed even that expectation. The realization made his blood boil with exhilaration.
After another violent collision, both Kaido and Madara pulled back slightly.
Kaido glanced at the four massive blades of Susanoo and shifted back into his Dragon–Human form. His Azure Dragon form, while powerful, was simply too large and easy to target. Those enormous blades had already grazed his body several times.
Watching Kaido dodge relentlessly, Uchiha Madara laughed loudly."Your strength is impressive," he said, "but it seems you still can't block my Susanoo."
As his words fell, the power of the Rinnegan surged outward without restraint.
The Susanoo beneath him expanded once more. Massive wings unfurled from its back, and the blades in its hands darkened, radiating an even more oppressive aura.
The Perfect Susanoo, now towering at over two hundred meters, instantly shattered the remaining hope held by the Three Calamities.
Jack's face twisted with bitterness."What kind of monster is this? How can it keep growing?"
At this moment, Kaido wasn't even the length of a single finger compared to the Perfect Susanoo. It was no longer a battle between equals—it was an ant standing before an elephant.
The Pirate World was no stranger to colossal creatures. Sea Kings, island-devouring goldfish, and even Zunesha dwarfed mountains themselves.But this was different.
This was human power.
Across the myriad worlds, everyone could feel the terrifying aura pouring off the Perfect Susanoo. Compared to it, they were nothing more than shallow streams before a boundless ocean.
If Kaido were still in his dragon form, he could at least rival it in size. But now, his only option was to find a way to get close to Madara himself.
"Madara's getting serious," Hashirama murmured. "I didn't expect him to use the Perfect Susanoo."
As the only person Madara had ever truly respected, Hashirama knew exactly how terrifying this form was. Even he would have to fight at full strength to face it.
The battle raged on.
Kaido was struck again and again, yet each time he recovered within moments. The regenerative power granted by the Fish-Fish Fruit was absurd. Still, both fighters understood that the outcome would ultimately be decided by Kaido's strongest move.
"What overwhelming pressure…"
Marco stared at the Perfect Susanoo, his expression heavy. His gaze flickered between Madara and Whitebeard. After a long internal struggle, he reluctantly admitted that even Pops, at his current peak, might not be able to stand against Madara.
Sensing Marco's gaze, Whitebeard laughed heartily."Gurarararara! Uchiha Madara, huh? I'd really like to fight him someday."
Seeing Whitebeard so relaxed, the crew slowly calmed down and continued watching.
Naruto World
The battle had already lasted for hours.
Naruto watched in stunned silence, only realizing later that his hands were soaked with sweat."Are those two… even human anymore?"
Sakura swallowed nervously."Forget fighting them. Just watching this is exhausting."
Kakashi instinctively gulped. If he were in that battlefield, his chakra would have been depleted long ago.
Tobirama inhaled deeply through clenched teeth. Even with Guy on their side, if Madara truly decided to destroy Konoha, Instant Transmission wouldn't save them. The moment they engaged him, they would be blown away.
Noticing Sarutobi's anxious expression, Tobirama spoke calmly,"Don't panic too much, Monkey. As long as the Will of Fire remains, Konoha will endure."
They were words his brother often used—but as Hokage, Tobirama understood the need to steady everyone's resolve.
"I hope so," Sarutobi replied quietly.
JOJO World
"Jotaro, look," Joseph said excitedly. "That Kaido's starting to lose ground."
Despite his terrifying recovery, Kaido was being steadily overwhelmed. Each swing of the Perfect Susanoo's hundred-meter blades split mountains and severed rivers. Under such relentless pressure, Kaido was forced back again and again.
Madara stared coldly at Kaido's battered form."I acknowledge your strength," he said. "But this battle ends now."
"Don't end it!" Kaido roared. He hadn't felt this alive in years. Ending the fight now would hurt more than death itself.
Madara's lips curled slightly. He raised all four massive swords.
"Hoo—ah!"
The Perfect Susanoo brought its blades crashing down. The sheer force of the wind howled like a passing train.
"Great Demolishing Wind — Thunder Bagua!"
Kaido roared as both Haoshoku and Armament Haki erupted across his kanabo. White-hot energy poured from his mouth as he swung upward with everything he had.
Crack—
A sharp sound rang out.
One of the chakra giant swords actually began to fracture.
Kaido clenched his kanabo with both hands, veins bulging as he resisted with raw strength.
The collision of two entirely different power systems produced a blue-and-black energy sphere that rapidly expanded between them.
"That is…" Shanks stepped forward. The energies had fused. What followed would be a world-ending blow.
Beckman watched the unstable sphere carefully. Thin cracks began spreading across its surface as it wavered violently between the blades and the kanabo.
"Ha!"
Madara's Rinnegan flared at full power. The blue light covering the four chakra blades suddenly intensified.
Boom!!!
A blue-black beam erupted from the sphere in opposite directions before detonating violently. Trees, mountains—everything within range was annihilated in an instant.
Madara and Kaido were swallowed whole.
The sunlight vanished. The world itself seemed to change color.
What had once been a vast valley was now a flat, lifeless plain stretching endlessly into the distance. Even the river had been completely evaporated.
Both figures were gone.
Silence gripped the myriad worlds.
Ultraman World
Jun stared at the desert that had once been a battlefield, his brows deeply furrowed."That attack… could probably erase an entire country."
Tartarus, now in the Trigga World, rested his chin on his hand."Insignificant to me," he said calmly. "But for humans to reach this level through their own power…"
A rare hint of admiration flickered in his eyes.
