Goku slammed into the wreckage of what used to be a gas giant, chunks of frozen methane and rock spinning away in every direction like shrapnel. His body screamed, ribs cracked, one eye swelling shut, but that wild Saiyan grin never left his face. Blood floated in tiny spheres around him as he pushed off a drifting moon fragment and shot forward again.
Saitama was already there waiting, arms crossed, looking bored even with his suit half shredded and a few bruises darkening his bald head. "You done yet? I felt that last one. Kinda."
"Not even close!" Goku roared. The blue-silver aura around him flickered, unstable, like it was fighting to contain something bigger. He'd pushed Ultra Instinct past its limit, and the backlash was tearing at his muscles, but he didn't care. This bald guy was the real deal. The first opponent in forever who made his blood boil like this.
They clashed again in the empty blackness between systems. Fists met fists. The shockwave erased a small planetary ring in the distance—millions of ice rocks turned to glittering dust in an instant. Goku spun mid-air and drove a knee into Saitama's gut, then followed with an elbow that sent the hero tumbling straight into a red dwarf star. The star wobbled, its surface rippling like water before Saitama punched clean through the core. The star collapsed behind him with a silent flash, going supernova and swallowing three nearby planets whole.
Goku laughed through the pain. "You're holding back, aren't you? Stop playing around and show me everything!"
Saitama landed on a barren rocky world, cracking the entire crust. "I don't do 'everything.' This is already more trouble than my sale on eggs." He leaped off the planet just as Goku fired a point-blank God Kamehameha. The beam punched straight through the world, splitting it down the middle. The two halves drifted apart slowly as the warriors shot past them, trading blows so fast the light bent around their fists.
They tore through another solar system. Goku's punches started landing heavier, each one carrying the weight of divine ki amplified by raw Saiyan rage. Saitama blocked most, but one uppercut caught him under the chin and launched him through a blue supergiant. The star exploded outward in a brilliant blue flash, its outer layers peeling away like an onion as Saitama burst out the other side, coughing once.
"Alright," Saitama muttered, wiping his mouth. "That one was actually annoying."
He vanished. Goku's instincts screamed, but even Ultra Instinct barely let him twitch before Saitama's serious punch connected with his back. The impact sent Goku hurtling across light-minutes, smashing through asteroid fields, two more planets—one icy, one volcanic—and straight into the heart of a binary star pair. The twin suns destabilized instantly, spiraling into each other in a violent merger that lit up the sector like the birth of a new galaxy. Goku screamed as the cosmic fire burned his skin, but he used the explosion to propel himself back at Saitama like a living bullet.
Their next collision was cataclysmic. Space itself seemed to groan. A shockwave rolled out that shattered a distant nebula, turning glowing gas clouds into scattered debris. Goku felt something inside him snap—not breaking, but unlocking. A new heat, deeper than anything he'd felt before. His hair started shifting again, the silver-blue bleeding into pure white with streaks of gold and black. Energy unlike anything he'd ever touched flooded his body.
"What the—?" Goku gasped, eyes wide. Power surged through him in waves, endless, boundless. Omni God. The name flashed in his mind like it had always been there, waiting. Every cell burned with infinite potential, growth without limit, the peak of divine Saiyan might mixed with something even the Gods of Destruction feared.
His aura exploded outward in a blinding white-gold pillar that pierced through galaxies. Nearby stars flickered and died under the pressure. A whole cluster of planets cracked and crumbled just from the aftershock.
Saitama's eyes narrowed for the first time. "Huh. That's new."
Goku didn't give him time to think. He moved—faster than thought, faster than instinct. One second he was there, the next his fist was buried in Saitama's stomach. The bald hero's eyes widened as the air was driven out of him. Goku followed with a barrage: left, right, knee, elbow, spinning heel kick that sent Saitama crashing through the remnants of three destroyed planets in a straight line. Chunks of molten rock and ice trailed after him like a broken comet tail.
"You're strong, Saitama!" Goku shouted, voice echoing across the void. "But I've been looking for this my whole life! This power… it just keeps growing!"
Saitama righted himself, spitting a glob of blood that froze instantly in space. He clenched his fists, that rare serious glare settling on his face. "Fine. One serious punch."
He threw it. The punch that could end anything.
Goku met it head-on with an open palm. The collision created a sphere of pure destruction between them—space ripping open, time stuttering. A black hole bloomed for a split second before their combined power shredded it apart. The backlash erased an entire arm of a nearby galaxy, stars winking out by the thousands.
But this time… Goku didn't budge.
He grabbed Saitama's wrist, twisted, and drove his forehead straight into the hero's face. Bone cracked. Saitama actually staggered. Goku didn't stop. He unleashed a furious assault, each hit heavier than the last, his Omni God energy multiplying with every second. Planets in far-off systems felt the tremors. Stars went dark as their light was sucked into the growing storm of power around the two fighters.
Saitama tried to counter, throwing punch after punch, but Goku flowed around them like he was made of liquid light. A devastating kick to the side sent Saitama flying into a massive yellow star. Goku chased him in, both of them burning alive inside the plasma, and slammed both fists down on Saitama's back. The star detonated instantly, a hypernova that lit half the universe for a brief, terrifying moment.
When the light faded, Saitama was drifting, suit in tatters, blood leaking from his nose and mouth, breathing hard. Goku hovered above him, white-gold hair flowing, eyes glowing with calm fury and joy at the same time.
"You're incredible, man. Really. But I can't stop now. Not when I finally feel this alive."
Saitama looked up, a tired smirk tugging at his lips. "Heh… guess the noodles are definitely cold."
Goku brought his hands together, gathering every ounce of Omni God energy into one final attack. The sphere between his palms swallowed the light of dying stars around them. "This is for everything you gave me. Kame… hame… HA!!!!"
The beam engulfed Saitama completely. The hero raised one last fist, trying to punch through it, but the infinite power behind the wave was too much. It carried him away, deeper into the cosmos, slamming through system after system, shattering planets and extinguishing stars in its path until he disappeared into the blinding distance, the beam fading only after carving a scar across the galaxy itself.
Goku floated there alone amid the wreckage—hundreds of planets gone, dozens of stars reduced to glowing embers or black holes. His new form slowly powered down, hair fading back to black as exhaustion hit him like a truck. He laughed weakly, coughing up blood.
Lord Zeno, we have enough energy now — don't we Goku stood alone in the void of space.
A white sphere appeared, Zeno materialized.
Yes, your battle was awesome — sadly that Saitama guy is not yet finished.
You both will have to play another time, Zeno snapped his fingers.
A void appeared.
They vanished.
