Surtur's immense form loomed over Asgard, a dark shadow cast across the realm as the fire demon fully regained his primordial power. His colossal figure towered above the city, his molten eyes burning with centuries of rage and fury. With a feral grin, Surtur pulled a massive sword from the seething flames, the weapon crackling with fiery energy, its surface shimmering like the heart of a star. The fiery blade spun in a wide arc, the immense weight of the weapon seemingly no obstacle for its master, who reveled in the completion of his task, his destiny fulfilled.
Beneath him, the battle between Hela and Thor came to an abrupt halt as the ground trembled beneath the fire giant's arrival. The air crackled with overwhelming energy, a wave of heat emanating from Surtur's presence, pushing against the gods below. Thor and Hela, both frozen in the face of Surtur's terror, instinctively knew that the stakes had changed. They were no longer fighting each other, they were fighting for survival.
Hela, ever relentless, raised her hand and summoned an unending storm of necroswords. The ethereal blades cut through the air like a deadly hailstorm, crashing into Surtur's burning body with sickening thuds. Each strike caused the giant to flinch, but it was clear, his resistance was beyond the power of her weapons.
"YOUR RESISTANCE MEANS NOTHING, ASGARDIANS!" Surtur's voice boomed, resonating across the heavens, his words tinged with an ancient, unyielding wrath. "WITNESS RAGNAROK!"
With a mighty roar, he lifted his massive sword high above his head, the fiery blade trailing sparks and embers as it descended toward the heart of Asgard. The ground itself seemed to tremble in anticipation, the very air thick with the promise of annihilation.
Thor's eyes widened in horror as the sword's trajectory became clear. Without hesitation, he poured every ounce of his strength into Gungnir. The spear crackled with violent arcs of divine lightning, the air around it crackling with raw power.
"BZZZT!"
A supercharged bolt of godly lightning shot forth from Gungnir, racing toward the descending blade with blinding speed. The instant the two forces collided, the very air seemed to implode, creating a vacuum of swirling winds and crackling energy. The lightning met the blade of fire in midair, a violent clash of opposing powers, and for a moment, neither gave ground. But Thor's lightning began to slow the descent of Surtur's sword, the fiery blade grinding against the force of the thunder.
But Hela, ever the pragmatist, did not hesitate. She joined the assault, unleashing an unrelenting barrage of necroswords into the fiery blade, each one striking with brutal precision, further stalling its fall. The combined efforts of the two gods were enough to hold back the blade, at least for a moment.
But then, Surtur's aura flared like a supernova, his immense strength surging as he summoned the full force of his eternal flame. The air grew unbearably hot, the very earth beneath them cracking and groaning in agony. The sword began to slice through the thunderbolt with terrifying speed, pushing through Thor's lightning with an unstoppable force. The ground beneath them trembled violently, and both Thor and Hela's eyes widened in realization.
The tip of the sword, burning with the intensity of a thousand suns, loomed ever closer, its fiery edge only inches from the heart of Asgard. It was clear, if the sword struck, the end of the realm would be sealed.
But just as the fiery blade inched closer, a loud CLANG rang out through the air, a shockwave of force that knocked both Thor and Hela off balance. William appeared between them, his duel-bladed spear held firm against the flaming sword. He thrust it forward, the weapon seeming to lengthen in response to his will, its gleaming shaft catching the fiery blade. The spear slowed the blade's descent, halting it just enough for the gods to catch their breath.
"SKKKKTTT!"
William's feet dug into the earth, carving deep trenches into the stone streets of Asgard as he braced against the overwhelming force of Surtur's sword. His muscles strained with the effort, but the spear held its ground. His aura flickered to life, a verdant green light rippling across his form. But as his power surged, it shifted, his energy rising to new heights, glowing with a golden hue as he activated his Super Saiyanite form.
The fiery sword began to slow, just barely, its descent grinding to a crawl under William's intense pressure. Surtur's eyes flared with fury, his molten gaze locking onto the warrior who had dared to challenge him. With a primal roar, the fire giant unleashed the full fury of his eternal flame, applying more force into the sword. William's teeth gritted as the blade began to push forward once more, his feet carving deeper into Asgard's streets with every inch the weapon gained.
But William held firm, his aura shimmering with a golden brilliance, his resolve unbreakable. The battle between their powers raged on, a struggle for the fate of the realm.
And then, from the distance, a figure emerged, a woman with flaming red hair, her fiery locks glowing like molten fire. She stepped gracefully out of William's ship, her gaze immediately falling upon the towering form of Surtur. Her lips curled into a smirk, a dangerous glint in her eyes as she surveyed the battlefield.
She licked her lips, a glimmer of excitement flashing across her face, before a pulse of energy surrounded her. In a burst of flames, a mystical bird materialized around her, wrapping her in a cocoon of fire. The bird took flight, its wings stretching wide and soaring into the sky as the woman's form merged with it, becoming the embodiment of the Phoenix.
"KAAAA!" A shrill cry echoed through Asgard as the massive Phoenix took flight and approached the currently ongoing fight with a hunger clearly visible in its eyes.
Surtur, the embodiment of flame and destruction, sensed a sudden shift in the air, a potential threat approaching. His fiery gaze snapped toward the source, and as he turned his massive, horned head, his molten eyes locked with the blazing orbs of the Phoenix. The clash of their fiery stares was like the meeting of two ancient forces, each vying for dominion over the flames.
For a brief moment, Surtur's control over his eternal flames faltered. A part of his domain began to slip beyond his reach, as the Phoenix's flames seeped into his territory. Rage swelled within him, and his power exploded outward in a fiery crescendo.
"YOU DARE?!" His voice rumbled like an infernal earthquake, filled with venomous fury. With a roar of hatred, Surtur swung his colossal blade, the fiery sword igniting the air around it as it streaked toward the Phoenix.
The mystical bird, unfazed by the towering giant's strike, darted with fluid grace, narrowly avoiding the deadly edge. Instead, it soared along the length of Surtur's massive sword, its mouth opening wide.
"SHUUUU!"
Flames from the sword poured into the Phoenix's gaping maw, an infernal energy feeding the bird's own flames. As the fire entered the Phoenix, its form grew larger, its flames intensifying as it absorbed the fiery essence.
But Surtur, his rage only building, was far from finished. His massive fist swung toward the Phoenix, and with a deafening CRACK, the blow landed, sending the Phoenix spiraling through the air like a ragdoll. It crashed into the charred remnants of Asgard's palace, its body slamming into what little of the structure remained.
"KAA!" The Phoenix screeched, its cry echoing across the heavens, as its fiery form collided with the shattered ruins, scattering flames in every direction.
Surtur, now advancing toward the downed Phoenix, raised his sword high, intent on finishing what he had started. But just as the fire giant began to close the distance, he felt a surge of energy behind him.
"WHOOSH!"
A massive blast of ki tore through the air, striking Surtur square in the back. The colossal fire giant staggered, his flaming body faltering as the blast sent him crashing to one knee. His flame-choked breath echoed through the air, but the fiery rage in his eyes only intensified as he slowly rose back to his feet, shaking off the hit with an angry growl.
"Ka... me..." Surtur began, his voice grating with fury. The flames around him darkened, shifting to an even more furious red as his power surged. "Ha... me..."
He twisted his head toward the source of the attack, William, standing defiantly at a distance. With an almost disdainful expression, Surtur angled his sword for a vertical slash, intent on cleaving William in two with one fell swing.
"HAAAAA!"
Surtur's sword descended with the force of a collapsing star, but William, unshaken, reacted in an instant. With a fierce grunt, he launched a concentrated blast of ki from his off-hand. The beam shot toward the descending sword with pinpoint precision, crashing into it with the force of a thunderstrike.
"BOOOM!"
An explosion of energy erupted, creating a shockwave that flattened the surrounding area, turning the ground into a wasteland of scorched earth. The two forces clashed, and the blade of Surtur's sword began to slice through the concentrated ki beam, steadily cutting through the massive wave of energy, inch by inch, as though it were a mere paper.
William stood unfazed, his body small in comparison to the towering behemoth before him. The sword's fiery edge inched closer to him, its burning heat warping the air around it. But William's resolve was ironclad. He clenched his teeth, his expression unwavering, as his aura swelled in intensity.
"Crackle!"
Dense arcs of lightning spiraled around William, his already upright hair standing on end as his energy surged. The very air around him seemed to hum with static, charged with an overwhelming force that pulsed through his body like an electrical storm.
A confident grin spread across his face as he saw the sword slow. Surtur, struggling to push the blade further, was now visibly exerting all his strength, his flames flickering with frustration. But William's own energy exploded outward in a tidal wave of ki.
"HAAAA!"
A deafening roar tore from William's chest, the sheer force of his energy shattering the very ground beneath him. His aura erupted, golden and verdant, expanding outward as he pushed against the fire giant's blade. The beam of ki intensified, widening and growing in size, dwarfing the sword in comparison.
Surtur's fiery body was bathed in the radiant energy, the blast surrounding him in a storm of pure force. The fire giant's expression twisted in a mix of fury and surprise as he was overwhelmed by the explosion of power. With an ear-splitting crash, he was sent hurtling backward, his massive form crashing into the ground, creating a vast crater that swallowed him whole.
The flames that once consumed him flickered and sputtered, and the ground beneath Asgard trembled as Surtur's flaming body was buried beneath a blanket of energy, leaving a massive hole in his chest.
Surtr, still reeling from the force of William's attack, began to rise once more, the flames around him flickering erratically. His massive body groaned as it moved, but before he could fully regain his footing, a sudden, searing pain shot through his arms.
Flames erupted from the air as a pair of sharp, blazing talons locked around his limbs, gripping him with an intensity that sent waves of agony through his fiery form. Surtr roared in fury, but the grip only tightened, each claw sinking deeper into his molten flesh.
"GET OFF ME, DAMNED BIRD!" His voice trembled with pure rage, and the very air seemed to quiver with the force of his fury. Surtr's gargantuan strength surged as he attempted to break free, but the Phoenix was relentless. It pressed its talons deeper, shredding his skin, tearing through the fire giant's body with an unyielding power that only intensified his torment.
With a sharp, predatory screech, the Phoenix opened its beak wide, its fiery eyes alight with the hunger of the hunt. It dove down, striking with the precision of a killer, and sank its beak deep into Surtr's neck.
"SNAP!"
The sound was sickening, a crack of divine bone as the Phoenix's beak tore through the fire giant's throat. A jet of lava-like blood erupted from the gaping wound, splattering the surrounding ruins in molten crimson. Surtr howled in pain, his massive frame writhing, but the Phoenix held firm, its talons unrelenting as it squeezed harder, draining the life from him.
Surtr's struggles grew weaker, each movement slower as the fire that had once surged within him began to dim. The Phoenix, unphased, continued to rip and tear, and with one final, decisive motion, it yanked out Surtr's divine core.
The core, glowing with the essence of an ancient and terrible power, was swallowed whole by the Phoenix.
"GULP!"
As the core passed into the Phoenix's flames, a wave of energy cascaded over Surtr. His massive body trembled, his flames sputtering and dying as his essence was ripped from him. The divine fire that had once fueled his existence began to drain away, leaving him an ashen husk.
Surtr's roars turned to desperate gasps, but it was too late. The weight of the Phoenix's talons pressed down upon him as he began to lose his flame-like color, his body turning from molten orange to a lifeless grey. His once-mighty form began to crack, his edges crumbling like charred remnants of a dying fire.
The Phoenix's gaze remained cold and unfeeling as it held him in place, watching as the fire giant's divine essence was consumed. Slowly, Surtr's form began to disintegrate, turning to ash as his divine power flickered out. The fire that had once made him a living force of destruction now withered away, and his body crumbled to nothingness, leaving only a pile of burnt, smoldering remains.
