Uchiha Madara pressed his lips into a thin line, a dark gleam flickering in his eyes.
If the shinobi of this era had already evolved into monsters on this level… then perhaps his grand resurrection plan could wait a little longer.
At Marine Headquarters in the world of One Piece, Fleet Admiral Sengoku sat frozen in his chair like a clay statue.
Even though he had braced himself—his nerves wound tighter than a drawn bowstring—the destructive force exploding across the screen still shattered the limits of his imagination.
He couldn't track the bald man's fists at all. Not a single trajectory.
But even through the screen, Sengoku could hear them.
Each punch rang out like a verdict from the god of death.
One word only.
Annihilation.
Beside him, "Iron Fist" Monkey D. Garp had long since entered a state beyond shock. His mouth hung open. Drool mixed with spit trailed slowly down his chin. He didn't even notice. He might as well have turned into stone.
Iron Fist?
The nickname suddenly felt absurd.
If his own life-praised fists deserved to be called "iron"… then what word could possibly describe the fists of that godlike bald man on the screen?
Vice Admiral Tsuru frowned deeply. "It's obvious. The peak combat power of that world is on an entirely different level from ours."
Even if this wasn't their war, power capable of destroying civilizations had forced its way into her thoughts.
Sengoku understood what she meant without her saying more.
The navy had to evolve.
He slammed his palm onto the table, the impact echoing through the command room.
"Pass the order! All marines begin hell-level training immediately! We will not remain frogs at the bottom of a well!"
Hero Association Headquarters — One Punch Man
"This… this ordinary-looking bald guy actually beat Boros?!"
S-Class Rank 2 hero Tatsumaki's pupils shrank violently. Her voice trembled with disbelief—and something uglier.
She couldn't accept it.
That bald caped clown she'd always dismissed… had done something even she couldn't.
And pride wouldn't allow her to admit defeat.
Not to him.
Meanwhile, the cyborg Genos looked like he was about to burst with pride.
"I knew it, Sensei! There's no way Boros could ever stand against you!"
But Saitama raised a hand and cut him off.
His expression was rare—serious.
"No, Genos. This fight isn't over yet."
He stared at the shattered remains of Boros on the screen, and something long forgotten flickered in his eyes.
Interest.
Someone destined to be his "future opponent" wouldn't fall to a few Normal Punches.
And sure enough—
On screen, Boros' body, blown into fragments, began reassembling in defiance of all physics.
In an instant, the battered alien stood again. Bloodied. Broken.
But burning with unrelenting battle intent.
Blinding white light shot from his eyes. Blue lightning cracked violently around him.
"You want to win? Then you'll be destroyed by my hands!!"
He rose into the air. Energy surged through him. A pale golden aura wrapped around his form.
"I'll unleash everything! I'll blast you—and the entire surface of this planet—into nothing!"
Lightning lashed outward like mad serpents. The ground split. Molten lava erupted from deep fissures, heat distorting the air itself.
The atmosphere grew suffocating.
Then—
A deep blue beam of absolute annihilation erupted from Boros.
The attack carried the weight of planetary extinction.
Lava rolled at Saitama's feet. His cheap white cape whipped wildly in the shockwave.
"Collapsing Star Roaring Cannon!!"
Thunder and lightning screamed around the beam.
The camera zoomed in.
Saitama's face became solemn.
For once, he acknowledged his opponent.
"Guess I'll get serious."
His voice carried a strange pressure, as if it crossed dimensions.
"Killer Move—Serious Series."
"Serious Punch."
In that single second, Saitama's presence climbed to an unreachable peak.
He threw his fist forward.
No hesitation. No fear.
The world shook.
The planet-destroying beam collided with his knuckles—
—and split in two like paper torn apart by invisible hands.
It roared past him on either side.
But Saitama's punch didn't slow down.
It pierced through the remnants of the beam and smashed directly into Boros.
The explosion swallowed everything.
Behind Saitama, the divided beam detonated into massive mushroom clouds.
In front of him—
Boros vanished.
The camera shot upward, breaking through the atmosphere into the cold silence of space.
The entire blue planet came into view.
And then—
A horrifying sight.
Across the cloud layer stretched an enormous linear scar, as if a god had sliced the sky in half with a blade.
The sky itself had been torn apart.
The camera returned to the battlefield.
Sunset light washed over the ruins. Wind drifted gently across charred earth.
Far away, Boros' broken body lay still.
Saitama stood with his back to the corpse, staring blankly at the distant horizon—at the scar he'd carved into the heavens.
The screen froze on the ruined landscape of City A.
Even with the most advanced technology and intelligence, human civilization looked painfully fragile before such power.
Then the word appeared.
The End.
...
World of Toriko
"This… this is insane! One punch—and he split the sky!"
Toriko stared at the massive crack in the atmosphere, completely dumbfounded.
Just moments ago, he'd been feeling proud of his own future feats.
Now?
They felt like a child's playground scuffle.
"Is that really human strength? That's terrifying…" Komatsu muttered, mind blown.
And yet Coco, shaken though he was, couldn't help laughing in awe.
"Man… that was awesome."
Hero Association
"So the final winner is Saitama?" asked Bang, the Silver Fang.
"Without question," Genos replied firmly. "The video already showed it. The victor is my master."
"But City A was completely devastated…" Atomic Samurai frowned.
The Association president looked thoughtfully at Saitama.
"If the future crisis truly comes… Bald Cape, we'll have to rely on you."
Saitama rested his chin in his hand, staring at the giant "End" on the screen.
Something felt off.
The excitement he'd felt during the fight…
Was gone.
Just like that.
"Too weak…" he muttered quietly. "Not interesting at all."
Five Kage Summit — Naruto World
At the summit, Mei Terumi rubbed her aching temples.
One world-shattering battle after another.
Even if they weren't from her world, the fear lingered.
What if…
What if beings like that one day appeared in the shinobi world?
She looked at the other Kage.
This couldn't be ignored.
"What would we do," she asked gravely, "if those otherworldly monsters suddenly arrived in our world?"
The Fourth Raikage frowned. "That's excessive worry. We're not even in the same dimension."
"But Boros wasn't from Saitama's planet either," Mei shot back. "And he crossed the universe to get there. We can't do anything like that."
Hiruzen Sarutobi exhaled smoke thoughtfully.
"Her concern isn't unreasonable. If Boros could travel between worlds… then perhaps some beings already possess that ability."
Disguised as the Kazekage, Orochimaru spoke softly, eyes glinting.
"What is your proposal, Hokage-sama?"
Hiruzen glanced at him, voice steady.
"Even without outside threats, the future already shows us facing Madara Uchiha. I propose immediate inter-village exchanges and cooperation. We must raise our collective strength."
"I agree," Mei responded instantly. "We must let go of old grudges. Our most certain enemy is Madara."
The Raikage shot a wary glance at Onoki.
Future cooperation or not… that old man was still tied to his father's death.
Ōnoki felt just as displeased.
But survival came first.
"Then let's continue the discussion," someone muttered.
Dragon Ball World
"Goku… do you think you could beat that bald cape guy?" Krillin asked quietly.
Goku grinned.
"I don't know. But he's crazy strong. I really want to fight him!"
The battle between Saitama and Boros had lit a fire in him.
He couldn't wait to test himself against someone like that.
Krillin shook his head helplessly.
"You're hopeless. A total battle maniac."
And Goku just laughed.
"....."
