After the battle with the Destroyer, Harry, the scientists and the Asgardians made their way to the site where the Bifrost[RS1[BB2] would open, the scene before them was a field of wrecked SHIELD vehicles, debris scattered across the landscape and fallen agents lying amid the ruins.

Harry's heart tightened as he scanned the devastation. The victory felt hollow, overshadowed by the suffering surrounding them. He knelt beside the wounded, his hands glowing faintly as he channelled his magic into healing them. He moved from one agent to the next, offering aid where he could, his mind distracted by the echoes of his defeat against the Destroyer.

Thor stood nearby, his brow furrowed with concern, gripping Mjolnir tightly as he raised his head to the sky, calling out to Heimdall. "Heimdall, open the bridge!" Thor's call echoed through the air.

For a tense moment, nothing happened. The air grew thick with uncertainty as Thor's call went unanswered. But then, with a rumble that seemed to shake the very ground, the sky above split open. The Bifrost began to swirl, its energy crackling as it prepared to transport them to Asgard.

Before they could leave, a battered Coulson approached Thor, flanked by several equally worn SHIELD agents. Dust clung to his suit, his usual composure just slightly rattled, but his resolve remained firm. Thor turned to face him; Mjolnir still clutched in hand.

"Know this, son of Coul," Thor said, his voice steady yet solemn. "You and I, we fight for the same cause—the protection of this world. From this day forward, count me as your ally. But on one condition..." Thor's gaze flickered toward Jane before landing back on Coulson. "Return the items you have stolen from Jane Foster."

"Not stolen," Coulson quickly interjected. "Borrowed." He glanced at Jane, offering a sheepish smile, but she only crossed her arms, unimpressed. Coulson cleared his throat and pressed on. "You'll get your equipment back, I promise. In fact, SHIELD would like to fully sponsor your research after today's events. If that's agreeable to you."

Jane nodded, but her eyes were not on Coulson; they were locked on Thor, filled with fear of what came next. She couldn't hide the tremble in her hands, the unspoken truth that this might be goodbye. Thor, sensing her fear, gently took her hand and pressed it to his lips.

"Whatever fate lies before me, you are part of it," he murmured softly. His voice, though confident, carried the weight of uncertainty. He didn't know if he would return, but his words were a vow—one that stretched across realms.

Without another word, Thor pulled her into his arms, his lips meeting hers in a kiss that was both tender and fierce, as if it might be their last. Jane melted into him, her heart aching with the knowledge that this moment could slip away, just as he might.

Harry looked at Thor as he approached the Bifrost, the shimmering light casting an ethereal glow on the wreckage and the fallen SHIELD agents. "Wait," Harry called out, stepping forward with a determined look on his face. "I'm coming with you."

Coulson's eyes widened, a mix of surprise and resignation crossing his features. He moved closer to Harry, speaking in a lowered tone. "Harry, you're not seriously thinking about going to another realm, are you? We barely made it through this battle."

Harry shrugged. "Look, I've fought worse things in weirder places. Besides, I can't let Thor, and his friends deal with Loki on their own."

Coulson ran a hand over his face, clearly debating whether he should argue. "You realize SHIELD isn't exactly equipped for... inter-realm diplomacy? We can't just send an owl or something to Asgard when something goes wrong."

Harry smirked. "Good thing I'm not relying on owls."

Coulson sighed, clearly exasperated. "You're a madman, Potter."

Thor, overhearing their conversation, turned to Harry, a mix of hesitation and respect in his eyes. "You wish to follow me to Asgard?"

"I can't let you face your brother alone," Harry said, his voice firm. "I've fought alongside you on Earth. Let me help you in your home."

Thor considered this for a moment. "You fought valiantly against the Destroyer. If you wish to stand by my side in Asgard, then I will not stop you."

Coulson shot Harry a last, resigned look. "Just don't get yourself killed, Potter. I don't want to explain to Fury that we lost our magical wildcard in another realm."

With a grin, Harry clapped Coulson on the shoulder. "I'll be fine. You'll get used to the weird stuff eventually."

Thor nodded in approval, and without further hesitation, Harry, Thor, and the Asgardians leapt into the Bifrost, the rainbow-coloured light engulfing them as they vanished from Earth.

When the Asgardians emerged from the Bifrost, they found Heimdall slumped over his controls, his golden armour dulled with the strain of battle. His sword, still lodged in the mechanism, crackled with residual power.

Thor's expression darkened as he knelt by Heimdall's side. "Get him to the healing room! Leave my brother to me," he commanded. Without another word, Thor bolted toward the exit, summoning the winds to carry him across the vast Rainbow Bridge, towards the golden castle where Loki was housed.

Harry stood there, feeling a sense of unease as the Warriors Three carefully lifted Heimdall, moving him toward the palace's infirmary.

"What am I supposed to do?" Harry asked, glancing at the towering expanse of the Bifrost Observatory and the endless stretch of the shimmering bridge beyond.

Heimdall, though weakened, fixed Harry with a piercing gaze. "The Bridge... it must be defended," he said, each word a strain. "Frost giants... or worse... they may come. I entrust that duty to you."

Harry stepped forward, determination filling his eyes. "But what if more than giants come? What if... Loki?"

Heimdall's gaze softened for a moment. "Loki's trickery knows no bounds, but your strength lies not just in magic, Harry Potter. You have a heart. Stand firm. This is no mere battle of swords and spells. It is one of will." He paused, then added, "Do not let your mind falter, no matter what comes through the Bifrost. Asgard's future may depend on it."

Harry nodded, swallowing the knot of anxiety building in his throat. As Heimdall was carried away to the healing chambers, Harry turned to face the glimmering expanse of the Bridge, knowing that what lay ahead would test him far beyond anything he had faced before.

The Rainbow Bridge shimmered beneath Loki's horse as he galloped toward the Observatory, its glass-like surface reflecting the aurora of Asgard's distant sky. As his eyes fell on the lone figure standing between him and his goal, the god of mischief slowed his steed, dismounting with a leap.

"You again," Loki said with a sneer, his voice laced with contempt. "What are you doing here?"

Harry's heart was pounding in his chest. He did not know what Loki was capable of, but he forced the fear down, channelling it into determination. "I'm here to stop you."

Loki raised an eyebrow, a smirk dancing across his lips. "A mere mortal like you? Stop me? How quaint."

Before Harry could respond, Loki flicked his hand, sending a wave of green energy flying toward him. Harry quickly cast a Protego charm, the magical shield shimmering to life just in time to block the attack. But the force of it sent him stumbling backwards.

"Is that all your primitive magic can do?" Loki taunted, his voice dripping with mockery. "You play with charms like a child with toys."

Harry gritted his teeth, refusing to be cowed. He responded with a barrage of spells—Stupefy, Expelliarmus, Reducto. But it didn't even phase Loki at all, the spells ricocheted off his glowing green shields, barely making him flinch.

"You can't win, mortal," Loki drawled, flicking his wrist to send another blast of magic toward Harry, who barely dodged it in time. "Your magic is pedestrian."

Loki raised both hands, conjuring illusions—dozens of himself, each one smiling wickedly at Harry. The bridge was now filled with copies of Loki, circling Harry like wolves closing in on prey.

Harry spun around, trying to figure out which one was real, his breath coming in short gasps. He fired a hex at one, then another—each disappearing in a puff of smoke. Frustration clawed at him, but he couldn't stop. He couldn't let Loki win.

A spell came from behind, hitting Harry squarely in the back. Agony shot through him like white-hot fire, every nerve in his body screaming in pain. It felt like he was under the cruciatus curse again, but this was more potent. He fell to his knees, as he struggled not to cry out.

Loki's real form stepped forward with a cold and cruel smile. "You see, mortal, you are out of your depth. You may have been something in your world, but here? Here you are nothing."

Harry gritted his teeth, pushing through the pain. With a desperate lunge, fired off a Blasting Curse at Loki. It hit one of the illusions, shattering it, but Loki himself stood unscathed, watching with detached amusement.

"You fight untrained," Loki mocked, stepping closer, his voice soft, almost pitying. "And hope to defeat a God!"

Harry forced himself to his feet, his legs trembling beneath him. "I won't let you win," he said through gritted teeth.

Loki's eyes gleamed with dark amusement. "Let me? You have no choice in the matter." With a simple gesture, he summoned a swirling storm of green energy, enveloping Harry and lifting him off the ground.

Harry fought to break free, his hand slashing through the air as he cast spell after spell—none of them breaking the grip of Loki's magic. He was helpless, suspended in the air like a puppet, his chest tightening as the force constricted around him.

Loki approached his face inches from Harry's, eyes glinting with superiority. "You are brave, mortal. I'll give you that. But bravery alone will not save you."

With a flick of his hand, Loki slammed Harry into the bridge, the impact knocking the wind from his lungs. Dazed, Harry struggled to get back up, his vision blurring. Loki towered over him, his presence suffocating.

"Stay down, mortal," Loki said, his voice soft but menacing. "You're only making this harder for yourself."

Harry, breathing heavily, pushed himself up on shaking arms, defiance burning in his eyes. "I'm not giving up."

Loki's smile vanished, replaced with a look of cold indifference. "Then you will suffer."

With that, Loki unleashed a torrent of magical energy that engulfed Harry, throwing him across the bridge. Harry's body skidded across the smooth surface, coming to rest near the edge, barely conscious. Every part of him ached. His magic—everything he had thrown at Loki—had been useless.

Loki stood tall; his eyes gleaming in victory. "You were never a threat, mortal. You were merely a distraction. And now, you're done."

Harry lay there, breathing shallowly, staring up at the darkening Asgardian sky. He had failed. He had been outmatched, outwitted. As darkness began to cloud his vision, one thought lingered painfully in his mind: He was powerless to stop Loki.

Loki heads to the observatory, starts it, and attacks Jotunheimen.

Thor soared through the air, riding the winds with Mjolnir in hand, the Bifrost's energy crackling beneath him. The Rainbow Bridge stretched out in front, feeding its immense power into the Observatory—a conduit of unimaginable destruction aimed directly at Jotunheim. As he neared the colossal doorway, Thor's eyes narrowed against the blinding light of the Bifrost, the air humming with the dangerous energy that could tear apart an entire realm.

Landing with a thud, he took in the scene before him: the controls of the Bifrost, frozen solid, locked inside a fortress of ice that shimmered menacingly under the energy's glow. The mechanisms were rendered immobile, and useless. And atop that icy prison, stood Loki. His dark armour gleamed in the harsh light, his expression colder than the ice beneath him.

"After all these years," Loki's voice echoed, carried by the power coursing through the Observatory, "and no one's ever dared to use it as a weapon."

Thor's heart clenched as he watched his brother—once a companion, now a threat—twisting the power of the Bifrost for his own ends. Mjolnir felt heavier in his hand as the weight of Loki's betrayal settled over him. The shimmering lights of the Bifrost glinted off his armour, casting long, dramatic shadows around the two brothers.

"You must stop this madness, Loki!" Thor bellowed, taking a step forward, his voice cutting through the din of the roaring energy. But Loki's smirk remained unchanged as if Thor's pleas were nothing more than the wind rustling leaves.

Thor rushed forward, raising Mjolnir high above his head, prepared to shatter the ice imprisoning the controls. But Loki was quicker. With a flick of his wrist, Gungnir—the spear of Odin—glowed with dark energy. Before Thor could bring Mjolnir down, Loki unleashed a devastating blast that struck the ice at Thor's feet.

Boom!

The force of the explosion shook the entire chamber, shattering the floor beneath Thor. The ground splintered, sending him flying backwards, crashing hard against the cold marble. Mjolnir clattered to the ground beside him as he struggled to catch his breath.

Groaning, Thor forced himself to his feet, pain shooting through his body with every movement. His vision blurred momentarily, but he could still see Loki, stepping down from the ice with a dangerous, measured calm.

Loki's green eyes gleamed with triumph, a predatory glint dancing in them as he towered over Thor, the Bifrost's violent hum accentuating the tension. "You always were slow to act, brother," Loki taunted, his voice low and dripping with venom. "While you wield brute strength, I wield power."

Thor staggered, chest heaving. "Loki… it doesn't have to be this way. We can stop this. Together."

Loki's smile vanished, replaced with cold determination. "No, brother. This is where it ends—for you, for Jotunheim, for everything."

With that, Loki raised Gungnir once more, and Thor knew this battle was only just beginning.

"You can't stop it," Loki said, his voice cold with satisfaction. "The Bifrost will tear Jotunheim apart."

Thor's eyes burned with disbelief and fury. "Why? Why would you do this?"

"To accomplish what Father never could," Loki replied, bitterness lacing his words. "To wipe them out forever. He'll understand when he wakes."

Thor's face twisted in anguish. "He won't! You can't murder an entire race!"

Loki's smile darkened. "Spare me. You, who would have slaughtered them all yourself."

"I've changed," Thor said, his voice steady but pained.

Loki's gaze turned icy. "So have I."

With a swift motion, Loki struck Thor across the face with Gungnir, sending him stumbling back. Thor quickly recovered, staring at his brother with sorrow and defiance.

"Fight me," Loki demanded, swinging the spear again. Thor caught it, the force reverberating through his arm, but instead of retaliating, he took to the air, racing toward the frozen controls.

Loki, frustrated, aimed Gungnir at Thor and fired, freezing him mid-flight like a puppet. "Is the throne worth all this, brother? What you've become?"

"I never wanted the throne," Loki sneered. "I only wanted to be your equal. Now fight me!"

With a brutal gesture, Loki flung Thor to the ground. Thor stood again, resolute. "I will not fight you, brother."

Loki's face twisted with rage. "I am not your brother. I never was."

Thor's heart ached. "This is madness, Loki…"

"Is it?" Loki mocked before firing Gungnir once more. Thor dodged, but Loki's venomous taunt followed. "What softened you so, Thor? A woman?"

Thor's silence confirmed it, and Loki's sharp laughter echoed. "It was, wasn't it? Perhaps I'll visit her when we're done here."

That was the final spark that ignited Thor's fury. With a roar, Thor and Loki clashed, their weapons meeting with a resounding crash. The chamber filled with the sounds of their battle—the clash of metal, the crackle of energy, and the shouts of rage and defiance. Lightning flashed around them as Thor raised Mjolnir high, calling forth a storm of epic proportions. Loki retaliated, summoning all the dark magic at his disposal, his eyes gleaming with a twisted sense of superiority.

The battle was fierce. Thunder roared in the sky above as Thor brought Mjolnir crashing down, narrowly missing Loki, who darted away with an agility born of years of trickery. Loki thrust Gungnir forward, unleashing another powerful blast of energy that Thor deflected with his hammer. The ground beneath them cracked and shattered, sending shards of the bridge into the air.

Harry, watching from the sidelines, knew he couldn't just stand by. His mind racing with spells that might turn the tide. As Loki prepared to strike Thor with a killing blow, Harry reacted instinctively.

"Stupefy!" he shouted, aiming at Loki. The red beam of light shot toward the god of mischief, but Loki waved his hand, deflecting it with a flick of his wrist.

"Foolish mortal magic," Loki sneered, his voice dripping with condescension. "You think your parlour tricks can match the power of a god?"

Undeterred, Harry fired off another spell, transfiguring a chunk of the bridge into a wall of stone that shot up between Loki and Thor. It bought Thor just enough time to regain his footing, but Loki easily shattered the barrier with a single blast from Gungnir.

"You're out of your depth, boy," Loki snarled as he sent another wave of energy toward Harry. Harry barely had time to raise a shield charm, the force of the blow knocking him back.

"Stay back, Harry!" Thor warned, his voice booming through the storm.

But Harry wasn't about to give up. Despite being outmatched, he pushed himself up from the ground, his heart pounding with determination. "I'm not letting him win, Thor!"

Loki chuckled darkly; his gaze fixed on Harry. "Ah, such bravery. How utterly pointless." He raised Gungnir again, this time aiming directly at Harry.

Before Loki could strike, Thor hurled Mjolnir, the hammer crashing into Loki's chest, sending him sprawling across the bridge. Thor rushed toward Harry, grabbing him by the shoulder and pulling him behind a nearby pillar of the observatory.

"You've done enough, Harry," Thor said, his voice firm but grateful. "But this is my fight."

Harry, breathing hard, nodded reluctantly. He could feel the magical power radiating from Loki—it was far beyond anything he had ever faced. But even in the face of that overwhelming force, he refused to feel defeated.

The two brothers resumed their battle, the air crackling with energy as Thor and Loki fought with everything they had. Harry watched, knowing this was a battle of gods, a fight he couldn't win. His help, however small, had been enough to tip the scales for Thor.

Thor, weary but unrelenting, finally faced Loki in the centre of the bridge. The two brothers locked eyes, and for a moment, there was a flicker of something—regret, perhaps, or the last remnant of the bond they once shared. Then, with a final surge of energy, Thor charged at Loki, prepared to end the battle once and for all. The two titans crashed through the observatory dome, landing heavily on the Rainbow Bridge.

Thor scrambled to his feet, his gaze scanning the debris-strewn bridge. Loki was perilously close to the edge, dangling over the chasm. His eyes were wide with a mix of fear and desperation as he looked up at Thor.

"Thor! Help me!" Loki's voice was a pleading echo across the Rainbow Bridge.

Thor moved towards the edge, his heart pounding with conflicting emotions. He reached down, his hand outstretched towards Loki's wrist. But as he grasped at his brother's arm, his hand passed through the illusion of Loki.

"Please…" Loki's fingers were slipping.

Just then, the real Loki materialized behind Thor. Before Thor could react, Loki plunged Gungnir into his chest. The spear's tip burst through Thor's armour, lifting him off the ground. Loki hurled Thor across the bridge with a savage throw.

Thor landed heavily, bloodied and dazed, but he pushed himself up to his knees. Loki stalked towards him, ready to deliver the final blow. Thor, with a determined grit, swung Mjolnir around. The hammer passed through Loki, revealing the illusion. Another Loki appeared beside the first, then another, and another. Thor swung wildly, each strike passing through nothing but illusions.

Exhausted, Thor fell back to his knees as the multitude of Loki grinned, their spears raised in a cruel circle around him.

"I was always cleverer than you," one of the Loki taunted.

Thor's eyes burned with a fierce resolve. "Yet still not clever enough."

With a mighty effort, Thor raised Mjolnir high above his head. The clouds above roiled as lightning crackled from the hammer. A massive bolt of lightning struck Mjolnir, which then split and struck each of the Lokis in turn. Each illusion dissipated into nothingness, leaving only the real Loki, who was hurled backwards by the force of the storm, his spear knocked from his grasp.

Thor staggered over to his fallen brother, Loki lying dazed on his back. Loki winced; his gaze filled with apprehension as he braced for Thor's final blow. But Thor merely stood over him, then stepped aside. Confused, Loki tried to rise but found himself pinned down by Mjolnir, which now rested atop his chest. Despite his struggles, Loki could not lift the hammer.

Thor glanced around, the urgency of the situation striking him. The Bifrost was still firing towards Jotunheim, its energy surging through the Bridge. He was at a loss, his heart sinking under the weight of impending disaster.

Loki's voice dripped with smug satisfaction. "Look at you, the Mighty Thor. With all your strength, what good does it do you now?"

Thor's eyes fell to the vibrating Rainbow Bridge, feeling the energy of the Bifrost intensifying. Inspiration struck him, and he realized the drastic action he needed to take.

He extended his hand towards Loki, summoning Mjolnir. The hammer flew back into his grasp. Loki looked on in bewilderment as Thor raised the hammer high, calling forth the storm's fury. Clouds gathered overhead, and thunder rumbled as lightning danced off Mjolnir. With a fierce cry, Thor brought the hammer down upon the Rainbow Bridge.

The impact was cataclysmic. The bridge rumbled violently, shaking the Observatory as if it were caught in an earthquake. A massive crack formed where Mjolnir had struck, and the Bifrost's energy began to escape through the fissure. Loki, panicking, tried to stop Thor.

"Stop! What are you doing?!" Loki's voice was filled with desperation.

Thor lifted Mjolnir again, his resolve unwavering. With a final, devastating blow, he struck the hammer down once more. The Bifrost shattered, its rainbow energy exploding outward in a blinding torrent. The force of the blast hurled both Loki and Thor into the air. The Bridge and Observatory were torn apart by the shockwave, their destruction advancing rapidly.

As they plummeted towards the chasm, Thor grabbed one end of Gungnir, while Loki clung to the other. They were moments away from being engulfed by the destructive wave of Bifrost energy when a powerful hand reached out and caught Thor's leg. He looked up to see Odin All-Father standing on the edge of the broken Bridge, having awoken from his Odin Sleep, his strength fully restored. Loki's eyes met his father's, searching for some sign of approval or redemption, but all he saw was a profound disappointment.

Thor's voice broke into a cry of despair. "No!"

But it was too late. Loki's grip failed, and he was swept away by the surging torrent of Bifrost energy. The debris of the Bridge and Observatory followed, disappearing.

Odin pulled Thor up onto the remnants of the Bridge. Exhausted and broken, Thor fell into his father's arms. Odin's voice was heavy with finality.

"It is over."

Author's Note:

Yes yes I know Harry acted like a pussy in the past two chapters. Like the first time Harry met Loki, I don't want Harry sympathising with Loki just yet. That opportunity will come. But then, how else will I show his progress if he doesn't face a bit of adversity and overcome it? Now that Harry is stuck in Asgard, what better to do than level him up? I had fun with the early chapters but the next ones are the better ones. I know that a lot of you are going to hate the story for such a weak portrayal of Harry, hence why I posted 2 chapters this week. You can hate on it this week so that we can move on from it and focus back on the story.

And that's a wrap for the Thor storyline. Now we start with my story line. Hehe. I can't wait for you guys to read the next lot of these chapters. I get to set up a lot of things for future arcs without having to worry about the movies until avengers start. I think the next few chapters will allow you to see where the story will actually be going.

I have a P. A.T.R.E.O.N with the name Bivz643, if you guys are interested in reading ahead. For now, you can read ahead to chapter 66 of this fanfiction. In that chapter, have Harry meeting Aldrich Killian. There is only one tier for $5 with the benefit being access to the library and that I will be posting 2 chapters per week there. I understand that not everyone can become a Patron and support me monthly. However, if you'd still like to read ahead, you can do so by getting the PDF version of the 4th and 5th arc of "A Wizard in the MCU" for $3 each at P. A.T.R.E.O.N. shop

Anyway, see you all next week. Happy reading.
