Reborn as a Saiyan in marvel

Myrina stood firm against the relentless waves of energy rippling across the battlefield, her black plate armor absorbing the residual heat and force from the combat raging before her. Yet, despite her resolute stance, Barda was steadily losing ground. Each new pulse of power forced her backward, her boots carving deep trenches into the ice as she struggled to resist the sheer force battering her.

"CRUNCH!"

With a desperate thrust, she drove her Mega-Rod into the frozen ground, anchoring herself just before she lost all control. Steam hissed from the rod's superheated surface as it clashed against the permafrost, sending cracks spiderwebbing outward. Panting slightly, she turned toward Myrina, her voice edged with urgency.

"What in the hells is going on?" Barda demanded, her breath visible in the frigid air.

Myrina did not answer immediately. Her sharp gaze remained locked onto the battlefield, unwavering. Only the slow, deliberate tapping of her dagger against her armor broke the stillness around her. The rhythmic clink, clink, clink against the black plate was a steady metronome amidst the chaos.

"We need to find an opening," she finally said, her tone measured. "But do we go after the new one… or Superman?"

Barda followed Myrina's gaze just in time to witness a moment of sheer brutality.

Darkseid loomed behind William, his enormous hand reaching to seize the back of the young warrior's head, prepared to grind him into the ice with the same merciless force he had inflicted on Superman. But William, sensing the movement, reacted in an instant. With a sudden, bone-crushing heave—

"WHOOM!"

He swung Superman like a living weapon, slamming the Kryptonian into Darkseid with the force of a meteor.

"GHHH-KA!"

The impact sent both titans reeling, their bodies crashing into the snow-covered battlefield. Blood splattered across the ice, steaming against the frozen wasteland. Darkseid gritted his teeth, an ember of rage igniting in his crimson eyes, while Superman staggered to his feet, his expression twisted in both pain and fury.

Then, an unspoken understanding passed between them.

They turned to William, their gazes burning with pure, incandescent rage. Their bodies crackled with energy as they both prepared their signature attacks, raw power coalescing at their fingertips.

William, undeterred, responded in kind.

Cupping his hands together, a brilliant blue sphere of energy flared to life in his palms, crackling and pulsating with raw Ki. "WENG!" The air itself vibrated as the attack built in intensity, a growing star of condensed destruction. But he didn't stop there.

A green construct, an almost mechanical projection resembling Iron Man's repulsor gauntlets, formed over his hands, lacing the Ki sphere with intricate energy threads woven from pure willpower.

The ground beneath them trembled violently.

"RUMBLE!"

The very foundations of the Fortress of Solitude began to crack and shudder as the power of three cataclysmic forces readied for release.

Then—

"BOOM!"

Superman fired first, his heat vision erupting in a searing beam of condensed solar fury. A heartbeat later, Darkseid's Omega Beams followed, twin streams of pure devastation laced with chaotic, entropic energy. Finally, William unleashed his own attack, the sheer force of his Ki-enhanced blast splitting the air with a deafening roar.

For a split second, there was silence, a terrifying pause before all three beams collided in a collision of apocalyptic proportions.

"BOOOOOOM!"

The explosion was instant and overwhelming. The sheer pressure of the impact shattered glaciers, sent avalanches cascading from nearby peaks, and obliterated the remaining structure of the Fortress. A shockwave of blinding light and concussive force tore across the battlefield, forcing Myrina and Barda to take immediate cover.

With swift instincts, they dove behind a thick ice wall, bracing as the storm of destruction washed over them.

At the epicenter of the blast, William found himself struggling against the combined might of both titans. Their beams pushed against his own, forcing him back inch by inch. His muscles burned, his skin blistered under the sheer intensity of the clash.

His golden aura wavered, flickering as he reached deep within himself.

His veins bulged. His body trembled. And then—

"KAIO-KEN x3!"

His roar split the sky.

A violent crimson hue overtook his golden aura, interlaced with dazzling streaks of radiant gold. His hair, once shining with the brilliance of a Super Saiyan, darkened to a pale red, streaked with lingering traces of blonde. His already bulked-up frame swelled further, every fiber of his being pushed to its absolute limit.

The gauntlets around his hands whined under the pressure, and in an instant, his energy beam tripled in size.

The balance of power shifted.

The once-overwhelming might of Superman and Darkseid now faced an unrelenting surge from William, forcing their combined attack to a precarious standstill. A high-pitched hum filled the air as the three energies fought for dominance, the very fabric of reality distorting around them.

The battlefield was no longer just a place of combat, it was a storm of sheer, unfiltered power.

"CRACKLE!"

Lightning crackled wildly around the collision point, streaking through the sky like veins of pure energy as the very atmosphere struggled to contain the sheer force being unleashed. The beams, once distinct in their individual power, began to falter—losing their structure, their cohesion unraveling.

Suddenly, a deep rumble echoed across the battlefield.

The three beams, unable to maintain their singular integrity, fused into a monstrous, chaotic mass of pure destruction. The energies—Superman's solar might, Darkseid's entropic Omega power, and William's volatile Ki—whirled together like a primordial storm, spiraling in on itself as it became increasingly unstable.

"CRACK!"

A shudder ran through the very fabric of space. Thick black fractures, jagged and ominous, split through the air like shattered plexiglass, forming an abyssal void that led to… somewhere else. A dark nothingness loomed on the other side, yawning wide like the maw of a cosmic predator. The swirling mass of unstable energy, drawn by an irresistible force, was sucked into the abyss, distorting as it funneled through.

Then—

"SNAP!"

The cracks in reality sealed shut with an audible snap, as if the universe itself had slammed a door to prevent further catastrophe.

For a moment, all three warriors simply stood in silent awe, staring at the space where the energy had vanished. Each of them, battle-hardened and powerful beyond measure, found themselves momentarily at a loss. The sheer unnaturalness of what had just occurred sent a ripple of unease through them.

Superman's crimson gaze flicked to Darkseid. Darkseid's burning eyes darted to William. William's own piercing stare shifted between the two of them.

Each thought the other was responsible for what had just transpired.

Then, without warning—

Darkseid moved.

A Boom Tube flared open beside him, its swirling portal warping the air around it. Without hesitation, the tyrant reached into its depths and withdrew a weapon that made even Superman's hardened expression shift to one of caution.

The Godslayer Spear.

Forged in the fires of Apokolips and bathed in Omega energy for over a millennium, the spear pulsed with malevolent life. Red lightning arced violently across its surface, crackling with enough entropic force to reduce even the most indestructible of beings to dust. Its jagged edges shimmered, exuding a sinister glow that twisted the air around it like a mirage.

Darkseid was done playing games.

His massive arm coiled back like a tightened spring, muscles rippling with godly might. Then—

"FWOOOSH!"

The spear rocketed toward William, a crimson comet slicing through the icy air.

Reacting instantly, William's hands flashed out as green energy flared to life. "CLANK! CLANK! CLANK!" A rapid series of massive construct walls materialized before him, shaped like thick vibranium plates, reinforced to withstand even the most powerful of forces.

He thought it would be enough.

He was wrong.

"HISSSS!"

The spear slithered.

Like a living thing, it wormed its way through the construct, twisting and contorting like a predatory serpent. It evaded the walls as though it possessed a will of its own, finding microscopic gaps between them as it carved an unerring path toward its target.

William's eyes widened. "A sentient weapon?"

His instincts flared, and he reacted immediately.

With a flick of his wrist, he summoned his own weapon from his system space—a staff, simple in form but dense with will energy. The staff morphed, its structure shifting as he willed it into a gleaming golden spear, its tip glowing with a sharp, unwavering resolve.

Then, with a fierce cry, he thrust his spear forward to meet Darkseid's demonic weapon.

"CLANG! CLANG! CLANG! CLANG!"

The two spears clashed in a furious sequence of brutal collisions, sparks of Omega energy and willpower erupting with every impact. The air screamed as shockwaves rippled outward, their sheer force carving deep trenches into the battlefield.

But something was wrong.

Cracks formed.

Not on Darkseid's spear, on William's.

The golden construct, despite its immense density and reinforcement, was buckling under the relentless strikes. Fractures spread like veins of failure, crawling across its surface with alarming speed.

Then, just as William prepared to reinforce his weapon—

SHWOOP!

Darkseid's spear abruptly disengaged, snapping back through the air and returning flawlessly to its master's waiting hand.

And then, without missing a beat, Darkseid charged.

Like a force of nature, he rushed toward William, his burning eyes locked onto his prey. His massive hands gripped the spear with lethal intent, each stride shaking the battlefield beneath him.

As Darkseid charged toward William, Superman attacked from the opposite side, his body a red-and-blue blur slicing through the icy battlefield. His fist was cocked back, trembling with restrained fury, glowing faintly with the raw energy of his Kryptonian might. His target, William's skull.

The sheer velocity of Superman's approach sent cracks rippling through the ice beneath him. He wasn't just aiming to hurt William. He was aiming to break him.

Darkseid struck first.

"WHOOSH!"

His Godslayer Spear shot forward, an extension of his indomitable will. The jagged, Omega-infused weapon burned the air itself, screaming toward William's chest with an unavoidable promise of death.

But William moved.

With a precise, fluid motion, he twisted his body, spinning like a coiled tempest. The spearhead barely missed his torso, slicing through the empty space where his heart had been mere milliseconds ago. The cold steel hummed as it passed, vibrating with lethal energy.

Yet—

"BOOM!"

Superman's fist connected.

William's world snapped sideways as a sickening crack rang out through the battlefield. The punch slammed directly into his ribs, its force catastrophic. A sonic boom erupted from the impact, sending shockwaves through the frozen terrain, splintering glaciers in the distance.

"CRACK!"

The unmistakable sound of fractured bone echoed in the air.

William's body was sent rocketing backward, a golden comet streaking through the sky, smashing through pillars of ice and sending debris flying in all directions. Snow and dust whipped into the air in his wake, obscuring the battlefield in a swirling white haze.

Superman exhaled sharply, a smirk tugging at the corners of his mouth. He had landed a direct hit. A solid one. A punch meant to shatter mountains had crushed William's ribs. Satisfaction flickered in his crimson gaze.

But then—

"THWACK!"

A colossal kick slammed into his side.

Superman barely had time to process what had happened before he was sent tumbling through the air, a blur of blue and red twisting uncontrollably before smashing into the icy ground, carving a deep trench through the battlefield.

Darkseid loomed over him for only a moment, but he had no interest in toying with the Kryptonian. He turned his burning gaze back toward William, his real prey.

Darkseid lunged.

His spear gleamed ominously as he closed the distance in a single, godly stride. The air screamed in protest as he brought the weapon down, a killing strike aimed directly at William's chest.

"WENG!"

The spear struck home.

Or, so it seemed.

As the dust settled, William wasn't dead. He wasn't even down.

The spear had stopped.

It had stopped in his grasp.

William lay on his back, one hand gripping the deadly spearhead mere inches from his heart. His fingers, encased in a thick, unnatural layer of bone armor, clamped down on the weapon's lethal tip. The Omega energy poured from the blade, hissing as it scorched his flesh. The bones covering his hands blackened, turning to ash, but still—

He held firm.

Darkseid's glowing red eyes narrowed. Impossible.

Then—

William moved.

A pulse of power radiated from his body, like the beating of a primordial war drum. His red aura flickered, its once-violent energy now burning away like embers in the wind.

And then—

Gold.

Blinding, furious, untamed gold.

The moment was instantaneous, yet eternal.

William stood up.

His body swelled with raw power. His muscles expanded, thick cords of strength flexing beneath his battle-worn suit, forcing the fabric to shift, rearrange, and mold itself to his ever-growing frame.

He was taller now.

For the first time, he loomed over Darkseid.

Not by much, but enough.

And then, his hair.

It grew.

What was once spiky and wild now extended past his waist, flowing in a golden cascade of pure, concentrated energy. His features sharpened, not with mere rage, but with primal focus. His eyes, now slitted like a predator's, burned with an eerie yellow glow, almost like twin suns.

Darkseid felt it immediately.

This was not the same man.

Not anymore.

The battlefield, which had been an arena of destruction and chaos, suddenly became still. As if the very world itself had paused to acknowledge what had just awakened.

William's aura roared around him, a golden inferno so bright that the ice at his feet melted into steaming pools. The storm clouds above parted, as though the heavens dared not obstruct the sight of what had just emerged.

This wasn't just power.

It was ascension.
