Reborn as a Saiyan in marvel

As Loki was being held below, in a nearby compartment the scepter began glowing briefly as if it received a remote command.

William, still recuperating from the previous battle, found solace in a room provided for his recovery.

Assuming a meditative stance, he focused on amassing his ki in preparation for the challenges ahead. It was during this moment of concentration that a blinking update notification caught his attention at the periphery of his vision, prompting him to mentally access the alert.

[DING... USER COMPLETED QUEST... BATTLE THOR: GOD OF THUNDER...]

[DING... REWARD BASED ON HOW LONG USER LASTS...]

[DING... C - RANK ATTAINED... TWO MINUTES & THIRTY SECONDS...]

[DING... REWARD DISPENSED...]

A light formed in William's lap momentarily blinding him before the light settles, he looks down and notices a capsule.

[Capsule Corp. Training Capsule]

[The Capsule Corp. Training Capsule is a high-tech device designed to enhance the wearer's training efficiency. Developed by the brilliant minds at Capsule Corporation, this capsule provides a controlled environment for intense training sessions.]

[The Training Capsule is a small, portable device that can be easily carried. When activated, it expands into a spacious training chamber equipped with advanced technology and holographic simulations.]

[The capsule includes a healing chamber that can rapidly regenerate the wearer's injuries and restore their stamina, making it ideal for recovery after intense training sessions.]

William was giddy with anticipation so much he accidentally lets off a bit of his aura.

"Whooosh!" 

A flash of ki destroyed his mirror and flattened smaller objects against the walls, before he regained his control and prevented his aura from leaking outside the room!

Glancing at his notification, he noticed he had received a Zenkai boost, elevating his power level to 6000, since he hadn't sustained significant damage from the spar.

William's vision shifted to his system space, where he found himself hovering in the sky above a solitary mountain.

At its peak, within a vast clearing, he placed the capsule and watched as smoke expanded and shrouded a large area, soon the silhouette of a large building that bore a CC logo on the front.

[DING... CONGRATULATIONS USER... CAPSULE CORP; TRAINING ROOM BUILT...]

William opened the large door and stepped inside; the inside was lit up in red and seemed to go on for miles causing him to stare in awe for a moment before a voice filled the silence.

[User please specify training parameters; all functions are voice activated]

As he pondered over a challenge that would be both exhilarating and formidable, his mind inevitably wandered to Thor. The mere idea of confronting the God of Thunder ignited a fiery zeal within him, readying him for an epic clash of might and power.

"Set up the surroundings to look like an uninhabited New York and I'll fight Thor the God of Thunder!"

A cascade of lights danced across the room, transforming the space until it mirrored a bustling city at midday, with towering, majestic skyscrapers reaching for the heavens!

Perched high on a skyscraper, an armored warrior brandished a stout hammer and bellowed his challenge into the wind.

Below, William, his ki flaring to life, nimbly sidestepped a descending bolt of lightning. With a fierce cry, he countered, launching a surge of verdant ki towards his adversary. Thor, unyielding, parried with his hammer, redirecting the energy blast into a neighboring tower with a thunderous impact.

"BOOOOOM!"

The skyscraper crumbled under the blast of green ki causing rubble to fly in every direction and if this place was populated would have caused hundreds of deaths.

Thor swung his hammer in a circle and used it to fly to his adversary with eyes crackling with the power of thunder soon he was right in front of William but when he thought he was about to hit the man Mjolnir went straight through with a ripple before his form vanished!

"BOOOM!" 

A solid kick landed on the back of Thor who was still confused about his attack not working, the unaware god was sent flying face forward and collided with a nearby building.

"RUMBLE!"

With a surge of lightning, Thor cleared the debris from his form, momentarily stunning William. Then, with a mighty throw, he hurled his hammer, propelling William across the sky like a shooting star. William crashed through several structures before landing with a thunderous strike of lightning, valiantly attempting to halt the hammer's relentless advance as it drove him, feet first, into the concrete, gouging a trench with his legs.

Before William had the chance to act, Thor was already on the move, his powerful strides closing the distance rapidly. With each leap, he bounded over entire streets, and then, with a leap propelled by the might of a storm, he landed. The ground shook with the force of his arrival, accompanied by the resounding boom of thunder!

"BOOOOOM!"

William was sent flying with blood flying out of his mouth and electrical burns on his flesh which seared his casual attire and soon he collided with the street in a massive crater with arcs of electricity flowing through the rubble, the dust was covering the crater but soon a powerful wind forced the dust to flow in all directions as a green burst of ki escaped from the crater and crashed into Thor!

"CRACK!"

"WHOOOOSH!"

The emerald flame coated form of William who had supercharged his muscles with ki threw a quick and powerful haymaker to the face of Thor making another crater of near equal size a few blocks away!

William still wreathed in green flames compressed these ki flames into a large overhead ball of energy!

He throws the orb at Thor who is still rising to his feet in the distance!

"BOOOOM!"

"RUMBLE!"

The surroundings shook uncontrollably and many of the buildings began to collapse on themselves around Thor who was sent back into the now deeper crater!

William was waiting, to see the results but it wasn't long before Mjolnir comes flying towards him but seeing as how William was expecting something like this, he had summoned his Power Pole and thrust it forward as he filled the staff with his green ki flames!

"Whooooosh!"

The air breaks as the two objects meet in the middle suddenly creating a vacuum before the mix of green ki flames and lightning reached critical mass at the center!

"BOOOOOOOOM!"

An explosion of green and blue light began to disintegrate the surrounding material, seemingly devouring it, as both objects were repelled back to their wielders. 

The two combatants locked eyes, each preparing a formidable attack. William conjured a sphere of green ki flames, the energy crackling intensely between his palms, while his opponent, Thor, summoned a tumultuous storm of cosmic lightning, its power and momentum building furiously.

"Ebon Burst!" William's voice thundered as he unleashed the ferocious orb of ki towards Thor, who, in the midst of charging his own attack, was only halfway ready. A resounding crackle filled the air as Thor conjured a bolt of lightning, hurling it with a mighty cry, "RAAAAH!" The bolt shot forth like a javelin.

The collision was imminent, the anticipation palpable: "BOOOOOOM!"

The clashing attacks create a spectacle resembling a green sun, with lightning dancing around it, culminating in an explosion that sends both combatants to their knees. 

William's face breaks into a wild grin, the Saiyan blood within him igniting with the thrill of battle.

Meanwhile, Thor, not designed for emotional displays, watches on with a stoic gaze, lightning crackling from his fingertips.

In a decisive moment, William charged at Thor, swiftly extending the Power Pole. It shot out, expanding rapidly towards the deity and slammed into his chest, forcing Thor's feet to carve into the street to halt his momentum. 

Thor, with a stern look etched on his face, seized the staff. He then summoned a surge of lightning into his free hand, sending a fierce bolt down the staff. The electric charge barreled towards William, catching him off guard with its ferocious intensity.

"BZZZZZT!" William is sent flying into a nearby street with a thin ribbon of blood streaking through his lips.

"AAAAHHHHHHHH!" William did his best to stop his momentum, but he was stunned by the lightning that was still coursing through him.

Thor wasn't going to let him off so easy, he summoned Mjolnir and began to chase William with the hammer extended and struck him with his lightning charged hammer smashing William into the ground!

"BOOOOM!" William is struck into the earth with lightning arcs surrounding the massive crater and Thor watching him from above!

William who was coughing up a small amount of blood got up with a struggle and with eyes that were blazing with green flames began to sputter and flicker.

"I believe I have the strength for one final struggle. What do you say, Thor? Shall we conclude with a grand finale?" The flames in William's eyes flared righteously and with his hands placed in that specific position he yells out "KAAAAA!"

Thor noticed his adversary was poised for the final blow and summoned his mightiest lightning, conjuring a tempest of storm clouds over New York, with lightning arcs cavorting within.

A blue orb of ki materialized in William's hands. "MEEEEEEE!" Lightning cascaded onto Thor's hammer and a green hue begins to fill the center of the blue orb.

"HAAAAA!" Thunder bellowed across the heavens and the earth trembled.

"MEEEEE!" An abrupt hush enveloped the area, as though a vacuum had emerged. "HAAAAAAA!"

A colossal beam of blue light, enshrouded by a smoky green aura, surged towards Thor. The God of Thunder, channeling lightning within his hammer and himself, launched into the air, hammer leading the charge into the heart of the energy maelstrom. 

As the two forces met, a cataclysmic explosion of cosmic energy erupted, radiating outwards. The initial shockwave shattered the nearby buildings, sending shockwaves further afield, toppling structures and wreaking havoc in an unstoppable cascade of destruction.

Thor, with his hammer thrust forward, was laboriously advancing through the energy beam. His expression was one of intense effort as he was losing momentum, and even the hammer's inherent power of flight seemed to falter.

Abruptly, the smoky green energy ensconced within the blue energy mass stirred to life, propelling itself forward. It pierced Thor squarely in the stomach and exited through his back, hurling the deity in the reverse direction. The remainder of the beam then engulfed his form, catapulting him through the earth's crust to a depth of several miles, where he came to rest, utterly still.

Legs trembling and arms hanging limply, William collapses to the ground, utterly spent. He had given his all in that final assault and could no longer sustain the ki flames enveloping him as they flickered out. Now, he could do nothing but lie there, panting heavily.

He struggled to his feet and began to walk toward a building where a bench was located and with a groan he sat down and exhaled a hot breath.

As William neared the entrance to the Healing Room, the earth trembled beneath his feet. Above, a thunderstorm of otherworldly scale brewed, its clouds stretching to the very edges of space, sending a shiver down his spine. 

Whirling around, he beheld Thor emerging from a colossal crater. Cloaked in a mantle of lightning, Thor's every step caused the pavement to crater, as though he bore the weight of hundreds of tons.

In the blink of an eye, Thor's hammer was hurtling towards William, propelling him into the building behind. Crashing into the lobby, William lay wounded, a pool of blood forming beneath him as labored breaths wheezed from his lips.

As he fought to stand, the muffled footsteps of Thor neared, only to vanish in a burst of light. The Chamber's emergency mode activated, transforming the area into a sanctuary of recuperation, with William at the heart of a restorative pool of healing waters.

.....

On the outside things were moving along normally with the group of hero's being influenced by the mind stone to increase their aggression towards each other at Loki's behest when a sudden "BOOOOOM!" an explosion rocked the Heli carrier, and it slowly began to fall from the sky which startled everyone on board who wasn't in a pocket dimension!

Iron Man urgently communicated, "Cap, we must reactivate that engine, or we're in a free fall!"

Captain America responded, "Instructions, now."

Iron Man directed, "Do you see that control panel? I need you to grasp the red lever and secure it. Leave the rest to me."

Without hesitation, Steve approached the panel and yanked the lever with formidable force, securing it as Tony ascended towards the malfunctioning engine. Employing the sophisticated instruments of his suit, Tony initiated the repair process, fusing severed components and reestablishing electrical connections.

Iron Man instructed, "Keep it stable, Cap! We're on the verge of success!"

Captain America urged, "Expedite, Stark!"

While Tony labored, the engine's condition began to normalize, yet the physical demand on Steve was colossal. With teeth clenched and resolve unwavering, he maintained his grip, resolute in sustaining the Helicarrier's flight.

Iron Man announced, "Success! The engine is operational again!"

With the engine's function restored, the Helicarrier regained its equilibrium and started to climb. In the aftermath, Tony and Steve exchanged a look of reciprocal esteem, their collaborative effort having deftly prevented a catastrophe.

Yet another blast shook the Heli carrier, propelling Bruce into a desk. This jolt caused him to lose his grip on the raging Hulk within, triggering an unstoppable transformation.

In a frenzied pursuit, he began to chase Natasha through the labyrinth of a server farm, consumed by a murderous rage, until a hammer's forceful descent sent him crashing to the level below.

Thor advances with determination, his grasp on Mjölnir unyielding. The Hulk, a colossus of rage, unleashes a deafening roar and pounds his fists into the ground, creating deep indentations. A tangible tension hangs in the air, emanating from the standoff between these two titans.

"Banner, I know you're in there! Calm yourself before more lives are lost." Thor tried to reason.

Hulk doesn't respond with words, only a guttural growl, and charges like a rampaging bull, Hulk barrels toward Thor, swinging his massive fist in a wide arc. The blow could level a tank.

Thor sidesteps nimbly, spinning Mjölnir in his hand, and delivers an upward strike to Hulk's jaw. The impact sends Hulk staggering but barely fazes him.

Recovering quickly, Hulk grabs Thor by the waist and hurls him through a metal bulkhead. Thor crashes through walls, sparks flying, before landing heavily in a hallway.

Thor pulls himself up, shaking off debris, as Hulk smashes through the hole he created, roaring in anger.

Thor, with a warrior's grace, propels himself forward, unleashing a flurry of mighty punches with Mjölnir. Each thunderous hit sends ripples through the Heli carrier, yet the Hulk withstands the assault, his fury only bolstering his formidable endurance.

Seizing a chunk of wreckage, a hefty segment of a metal door, the Hulk wields it as a makeshift baton, bringing it down on Thor with crushing force. Thor, undaunted, hoists Mjölnir in defense, but the impact forces him down on bended knee.

Channeling the tempest's wrath, Thor commands Mjölnir to call forth a surge of lightning, striking the Hulk with a dazzling flash that momentarily sears the darkness. The Hulk bellows, a primal sound of agony, but recovers with a ground-shattering pound of his fists, sending a tremor that disrupts Thor's stance.

Recognizing that Hulk's immense strength is almost unparalleled, Thor summons the full extent of his Asgardian power. With Mjölnir in hand, he soars into the sky, gaining speed and agility. Circling Hulk, Thor unleashes a barrage of lightning-infused blows upon Hulk's back and shoulders.

Fueled by rage at Thor's aerial advantage, Hulk springs up with an astonishing velocity, seizing Thor in midair. With a powerful throw, he sends Thor crashing down, creating a crater on the deck of the Helicarrier.

As Hulk descends to deliver the final blow, Thor channels his strength and flings Mjölnir forcefully. The mystical hammer strikes Hulk squarely in the chest, propelling him into a wall with such force that the entire structure trembles.

The two warriors, though worn and weary, stand resolute in their confrontation.

With a bellow that echoes through the air, Hulk hoists an enormous piece of machinery and hurls it towards Thor. Thor, quick to react, uses Mjölnir to deflect the projectile, but fails to notice Hulk's swift advance. In a display of raw power, Hulk ensnares Thor, slamming him into the ground repeatedly, each slam leaving a crater in its wake.

In a fervent effort to shift the battle in his favor, Thor calls upon the fury of the storm. Bolts of lightning dance across the Heli carrier, bombarding Hulk with a series of electrifying strikes. Despite the onslaught, hulk wavers but does not fall, his figure emanating steam from the relentless assault.

Before the fight can escalate any further an explosion shook the Heli carrier which opened up the wall and sucked the Hulk out forcefully and all of a sudden, the green goliath was plummeting to the earth in free fall.

Thor, despite his wounds and weariness, remains unyielding as he watches the Hulk fall. Drawing deep, labored breaths, he steels himself for the battle ahead, a determined whisper escaping him, "By Odin's beard, what a formidable adversary he is." he says as he witnesses the hulk slam into a warehouse.

The damage caused by their battle leaves the Heli carrier in even worse shape, but Thor knows the fight was necessary to prevent Hulk from causing more destruction.

In the midst of the chaos unleashed by Hulk's rampage and the concurrent assault by Loki's minions, Loki found the opportune moment to enact his escape. The valiant Agent Coulson, who had earlier wounded Loki with an advanced weapon, fell to Loki's hand. However, Thor quickly confronted Loki during his attempted departure.

To Thor's astonishment, he seemed to phase through Loki as if he were merely an apparition. As Thor regained his stance, he turned to find Loki grinning maliciously at him. With the press of a button, Loki ensnared Thor in a cage designed to withstand even the Hulk's formidable strength.

"LOKI DON..." Thor attempts to say before Loki presses the button and opens the trap door below.

Loki smirks with triumph as he goes to gather the tesseract and recover his staff.

Thor, trapped in a spinning glass cage plummeting through the sky, furiously punched at the walls. As the ground rapidly approached, he realized time was running out. With no other choice, he summoned the power of his mighty hammer and shattered the cage, freeing himself just moments before it smashed into the earth below!

He began to fly back to the Heli carrier that had become stabilized in the sky with billowing smoke flowing from one of the engines that was targeted.

...

William who was resting in the healing room within his training chamber was nearly fully healed but when he opened his eyes, he noticed an aggressively flashing notification in the corner of his vision and activates it as it seemed important.

[DING... 2X ZENKAI BOOST ACHIEVED]

[DING... MILD LIGHTNING RESISTANCE PASSIVE GAINED]

[POWER LEVEL: 12000]

[SYSTEM QUEST: DEFEAT THE CHITAURI INVASION!]

Overwhelmed with amazement at the outcome, William decided to gauge the extent of his newfound power. With a nonchalant flick of his wrist, he conjured a massive sphere of ki energy and hurled it towards a conjured floating target.

The moment it made contact, a thunderous "BOOOOOM!" echoed as the seemingly effortless ki orb detonated, unleashing a tempest of green lightning that danced wildly within the ensuing dust cloud.

With an impressed expression on his face, he noticed the quest notification and nodded, it was nearly time!

William left the chamber and exited his mental space to wake up and notice that half his room wall was smoking rubble and looked around casually, it seemed he had missed the attack, and everyone was running around hectically!

"I'd better go meet up with the rest of the team!" William says with a yawn as he moves down the hallway

As he entered the meeting room everyone turned to face him before returning to the conversation, Stark gets a notification from pepper that a horny guy is on the top of his tower and begins to come to his conclusion that Loki is attempting to open a portal using the tesseract and allowing a chitauri army to flow into earth without having to traverse a great distance through space.

Captain America gathered the team that couldn't fly and began to head to a quin jet to head to the city nearby.

William, Thor and Iron man flew in a delta pattern as they followed closely behind, they were closing in on the city when a large beam of light ascended the sky and opened up a hole in space allowing thousands of chitauri soldiers to flow into earth as they began to open fire on their surroundings!

[THE INVASION HAD BEGUN!]
