IRON MAN: BROTHER DON'T CAUSE TROUBLE

The Leviathan roared, its enormous, grotesque form plummeting toward the shattered city below. Each beat of its biomechanical wings sent shockwaves through the air, shattering windows and hurling debris in all directions. Its glowing, soulless eyes locked onto John as if recognizing him as a true threat.

Hovering in the air, John met its gaze with unwavering determination. The raw power radiating from the beast was far beyond what he had expected—stronger, more resilient.

"Why does it seem stronger than in the movie?" John thought. "This thing is a living force of destruction."

His instincts screamed at him to move as the Leviathan opened its monstrous maw, revealing rows of jagged, burning-hot fangs. A deep, guttural growl built in its throat before—

BOOM!

A torrent of energy erupted from its mouth, a beam of plasma-hot destruction. John barely had time to react, twisting his body midair as the blast seared past him, melting a building into molten slag. The heat washed over him like an inferno, his hooded cloak whipping wildly in the wind.

"That was close."

John narrowed his eyes at the Leviathan and activated the Wind Rune. With a flick of his wrist, a violent gale erupted beneath him. The air bent to his will, forming jagged tendrils that lashed out at the Leviathan.

The beast screeched as the wind coiled around it like an unbreakable cage.

John clenched his fists. "Let's see you get out of this."

In his spiritual sea, the Wind Rune flared brighter, and the air solidified. The invisible prison tightened around the Leviathan, its biomechanical plates creaking under the pressure as it thrashed violently.

Inside the Helicarrier

Nick Fury and Maria Hill stared at the screen in stunned silence.

"Sir…" Maria whispered. "Did he just—?"

"Yes," Fury muttered, his one eye narrowing. He had seen many things in his life, but this? A single man wielding multiple powers? That wasn't just superhuman—it was something else entirely.

"Keep recording," he ordered, his voice calm but laced with curiosity.

---

John wasn't done yet.

With a flick of his wrist, he summoned fire butterflies. Tiny embers flitted through the air before landing on the trapped Leviathan's armored hide. It roared, thrashing violently, but the wind cage held firm. Within seconds, the flames spread like wildfire, licking across its plated exoskeleton.

But after a moment, the flames extinguished, leaving the Leviathan still intact.

John wasn't discouraged.

A flaming fireball the size of a boulder ignited in his right hand, while a sharp, glimmering ice arrow formed in his left. Above him, the storm churned as lightning bolts crackled.

John didn't hesitate.

The fireball came first, smashing into the Leviathan's head in an explosion of scorching flames. The beast screeched in agony, its plated armor turning blackened and brittle from the intense heat.

Before it could recover, he fired the ice arrow. The frigid projectile pierced through its scales, freezing everything in its path. Frost spread rapidly, coating parts of the Leviathan's body in an unbreakable layer of ice.

Then came the lightning.

John thrust his hand forward, summoning a blinding bolt from the storm above. The air split with a deafening boom as the bolt struck the frozen part of the Leviathan, shattering the ice and sending cracks rippling through its armor.

Little further away, Clint Barton let out a low whistle. "Damn, he's not holding back."

"_____" Natasha reloaded her pistols in a daze, unable to look away from the battle.

The Leviathan thrashed inside the wind cage, its glowing eyes filled with rage and desperation. Every attempt to break free was met with resistance—the powerful gales constricted its movements, stealing its momentum.

But despite its struggle, John could tell… this thing was tougher than it looked.

He had expected his attacks to cripple the creature, but even after enduring fire, ice, and lightning, it still moved, still resisted. Its plated armor, though scorched and cracked, remained intact, and its roars only grew more furious.

"Alright then," John narrowed his eyes. "Let's take this up a notch."

Summoning a vortex of burning embers, John combined fire and wind, forming a devastating flame cyclone. The fiery vortex twisted violently, its heat distorting the air around it.

With a flick of his wrist, he hurled it at the Leviathan.

The moment the inferno struck, the beast let out a spine-chilling screech as flames crawled over its body, eating through its armor. The ice from John's previous attack reacted violently with the heat, causing an explosion of superheated steam—pressure building inside the Leviathan itself.

The beast lurched, its movements becoming erratic.

Hawkeye watched the battle unfold, shaking his head. "Okay, seriously. Are we sure he's human?"

Thor, gripping Mjolnir, nodded approvingly. "Perhaps not. But he fights like a warrior."

Inside the S.H.I.E.L.D. Helicarrier, Nick Fury continued watching in silence.

"Wind power, fire control, lightning strikes, and now... an storm?" Maria Hill muttered, shaking her head in disbelief. "Sir, this is beyond what we thought."

Fury's jaw tightened. His instincts had been screaming at him ever since John's arrival. A man with this much power, and we barely know anything about him.

That wasn't a comforting thought.

"Just what the hell are you, Arcanist?" Fury thought, tapping his fingers against the console.

High above, hidden within a crumbling skyscraper, Loki clenched his jaw. His once-confident smirk had long vanished.

This was not how things were supposed to go.

The Chitauri were losing—badly.

The Avengers weren't just holding their ground; they were winning.

Steve Rogers fought bravely, directing his allies while deflecting energy blasts with his shield. Thor was a living storm, lightning cascading around him as he tore through enemies. Tony Stark, ever the showman, weaved through the sky, raining down precise repulsor blasts. Even Banner, the mindless brute, was a nightmare, tearing through Chitauri like paper.

And then there was him—

Loki's fingers tightened into a fist.

The so-called "Arcanist" was unlike anything he had expected. A single mortal, wielding elemental forces like a god. Fire. Ice. Wind. Lightning. Was there any limit to his power?

Loki's pride refused to let him admit it, but deep down, a cold dread coiled in his gut.

The Avengers weren't just winning. They were breaking his army.

"Damn you, Avengers. Damn all of you!"

His hand trembled with fury.

But he wasn't beaten yet. No, he had one last trick.

Reaching into the void, he whispered an incantation. A swirl of cold energy surrounded his fingers before something materialized in his grasp.

An artifact—a staff with a round crystal on top.

This was the real Destroyer Summoner Artifact.

Asgard's previous Destroyer was merely a copy, a failed imitation controlled by Gungnir, his father's weapon.

Loki's lips curled into a slow, wicked grin.

"Father never thought of this."

"If the Chitauri aren't enough… then I will summon something far worse."

The real Destroyer.

As icy power surged through his veins, Loki's pulse quickened.

"This war isn't over."

Not yet.
