Midnight. Guardians' HQ.
The call had come without warning.
One moment, the Guardians of the Globe were scattered across the planet—fighting crime, saving lives, or arguing over pizza toppings—and the next, every single one of them got the same urgent signal: Emergency Protocol Zeta. No explanation. No location data. Just a single directive:
"Get to HQ. Now."
Red Rush arrived first, his crimson blur streaking into the hangar like a comet. Then War Woman, cracking her knuckles. Darkwing dropped from the shadows. Martian Man phased through the wall. Aquarius flopped out of his teleportation pod like a disgruntled salmon.
"Anyone know what's going on?" War Woman asked, adjusting her bracers.
"No clue," Red Rush replied, tapping his foot at impossible speed. "Just said Zeta. Never used that before."
"Where's the Immortal?" Green Ghost asked, forming from green mist beside them.
"He'll be here any second."
And then he was, stomping into the hall with a scowl.
"Who called us?" Immortal growled. "Cecil?"
The room answered with silence.
Then something shifted in the air.
A gust. A blur. A whisper of pressure.
They turned.
Omni-Man hovered above them, arms crossed, cape fluttering in the stale ventilation. His eyes gleamed with quiet, unsettling intensity.
"Why are you here?" Immortal asked, stepping forward.
Omni-Man didn't answer.
Instead, he launched himself at War Woman.
The fight erupted like a bomb.
Elsewhere. Just moments earlier.
Saitama wandered into the hallway of the Guardian HQ, dragging a bag of fast food. He'd been craving curly fries and took a wrong turn somewhere in Kansas. Next thing he knew, he was walking past a giant steel door that said "Authorized Personnel Only," which naturally made him curious.
"Wonder if they've got a microwave," he muttered.
Then, a scream echoed down the corridor.
Another.
And then the unmistakable boom of fists on flesh.
Saitama blinked, then casually walked forward, sipping a soda.
Back in the battle.
Red Rush zipped between punches, landing rapid blows that barely staggered Omni-Man. War Woman landed a hammer strike that cracked the floor. Martian Man wrapped him in psychic coils, while Green Ghost phased through his side, trying to disrupt his organs.
Nothing worked.
Nolan moved like a nightmare—ripping through them with surgical brutality. Red Rush went first, his skull crushed mid-save. Green Ghost barely formed before Omni-Man crushed her core. Martian Man's tendrils splattered against the wall.
War Woman screamed and charged.
"ENOUGH!"
Omni-Man met her in mid-air and drove her into the ground, cracking the floor beneath them. Her mace clattered away.
And then—
A plastic cup bounced off the back of Omni-Man's head.
He turned.
Saitama stood at the door, holding a nearly empty soda and a half-eaten burger.
"Oh," Saitama said. "You again."
Omni-Man stared. "You don't understand what's happening here."
"I'm starting to," Saitama replied, stepping into the room. "You really suck at making friends."
Darkwing crawled across the floor, bloodied. "H-Help…"
Saitama sighed, tossing the burger aside.
"Man. I was gonna eat that."
Omni-Man flew. A sonic boom cracked the air as he shot toward Saitama, fist raised to obliterate him in a single, surprise blow.
But Saitama wasn't there anymore.
He was behind him.
And he casually tapped Nolan on the shoulder.
Nolan turned—only to be rocketed through four walls with a flick.
Dust exploded from the corridor.
Saitama stretched. "Alright. Let's try this again."
What followed was a beatdown the world would never see.
They traded blows through the sub-levels. Omni-Man roared in Viltrumite fury, pummeling with everything he had. He burned through oxygen. Crushed steel. Reduced bulkheads to rubble.
Saitama yawned.
Nolan tried a sonic scream—Saitama shoved a burger into his mouth.
Nolan tried to gut-punch him—Saitama countered with a lazy slap that flipped him like a pancake.
The fight ended when Saitama, now covered in drywall dust and holding a bent straw, sat on Nolan's chest.
"You done?"
Omni-Man didn't answer. His eyes burned with rage—but he didn't move.
Saitama stood. "Thought so."
Moments later.
Cecil arrived at Guardian HQ to find chaos, blood, and broken walls.
And Saitama sipping another soda.
"...You."
"Me."
"Where's Omni-Man?"
"Taking a nap. Bad attitude. Needs to cool off."
Cecil eyed him. "You saved the Guardians?"
Saitama glanced at the survivors — a barely conscious War Woman, a twitching Darkwing, and Aquarius, who had been hiding under a desk.
"Some of 'em," he said. "They fought well. But your Viltrumite guy? He's got issues."
Cecil didn't argue.
Instead, he walked toward the control center, muttering, "God help us. This bald bastard might be our best chance."
Back at the Grayson house.
Mark woke to sirens in the distance.
His mom, Debbie, stood in the hallway, worried. "Something's happened. News is saying the Guardians were attacked."
Mark's heart dropped. "What? Who?"
"They don't know."
Outside, on the lawn, Saitama appeared like a ghost.
He held up a burger bag. "Got you one. Long night."
Mark looked at him, confused. "What happened?"
Saitama handed him the bag.
Then looked up at the stars.
"Let's just say… things are about to get weird."
