This is heavy AU so some characters will be stronger than cannon and the story will not strictly follow canon plot line.

Earth-15986
New York
It was a normal sunny day in New York. It had only been a few years since superheroes started to appear—and with them, villains. But even so, the general public felt safer than ever before. From Iron Man fighting terrorists across the world to the new hero Spider-Man patrolling the streets, it seemed like things were finally looking up.
Until today.
Everyone in the city saw it. The sky, once bright and clear, was suddenly overshadowed by a massive portal. Silence fell over the streets as people stared, holding their breath. Then, chaos erupted.
From the swirling void came thousands of beings, their forms twisted between organic and mechanical. They moved with terrifying coordination, their reptilian bodies enhanced by cybernetic implants. Without warning, they attacked. Buildings crumbled under their assault, cars exploded, and terrified screams filled the air as the city fell into panic.
Before the destruction could spread further, the Avengers arrived. Iron Man, Captain America, Thor, and the others wasted no time, charging into battle. But it quickly became clear that even Earth's mightiest heroes wouldn't be enough to stop this invasion alone. The enemy was too many, too strong.
Then, reinforcements arrived.
Some were well-known—Spider-Man swung into action, the Fantastic Four emerged from the Baxter Building—but others were new, stepping into the light for the first time. Heroes that had yet to make a name for themselves took a stand, defending their home with everything they had. The tide of battle shifted. What would later be known as The Battle of New York had truly begun.
But amidst the chaos, something else happened—something no one noticed. For just a brief moment, the very fabric of reality trembled, ripples spreading through the universe itself.
Something big was coming. Something that would change everything.

Runeterra
Demacia
The rhythmic clash of swords rang through the air as young cadets trained under the watchful eyes of their mentors. Garen Crownguard, the Might of Demacia, stood with arms crossed, his expression firm yet approving. Beside him, Fiora Laurent, the Grand Duelist, observed with sharp, calculating eyes, her posture poised like a blade ready to strike.
"They're slow," Fiora remarked, barely concealing her disapproval. "Their footwork is sloppy. If this were a real duel, half of them would already be dead."
Garen exhaled through his nose. "They're learning, Fiora. Not everyone is born with a blade in hand."
"Then they should train harder," she replied, folding her arms. "Weakness is not something Noxians will forgive."
Before Garen could respond, the sound of approaching footsteps drew their attention. From the entrance of the training grounds, Prince Jarvan IV strode forward, clad in his regal armor, his golden lance resting against his shoulder. Beside him walked Shyvana, the half-dragon warrior who had fought countless battles by his side. Her presence, as always, was both intimidating and reassuring. Walking just a step behind was Luxanna Crownguard, Garen's younger sister, her usual cheerful energy dimmed by the serious atmosphere.
Jarvan nodded to Garen and Fiora. "How are the recruits?"
"Some show promise," Garen said. "Most still have much to learn."
Fiora scoffed. "That's putting it lightly."
Lux gave a small smile but quickly turned her gaze to the trainees, as if lost in thought.
Before the conversation could continue, the ground beneath them trembled. It wasn't an ordinary quake—it was something else. Something unnatural. The tremor passed through them like a ripple, leaving a strange hum in the air. The five exchanged uneasy glances.
"What was that?" Shyvana asked, her grip tightening on her weapon.
"I don't know," Jarvan said, his voice wary.
Suddenly, a glowing blue circle appeared beneath their feet, pulsating with energy. There was no time to react. Before any of them could move, the magic surged upward, engulfing them in blinding light—
And then they were gone.

Noxus
In the heart of Noxus, deep within the Immortal Bastion, the ruling figures of the empire gathered. At the head of the grand war table stood Jericho Swain, the visionary Grand General, his crimson eyes glowing faintly beneath the dim torchlight. His expression, as always, was unreadable, his mind constantly three steps ahead of everyone else in the room.
To his right, Darius, the Hand of Noxus, stood with his arms crossed, his axe resting beside him. His mere presence radiated strength, his scowl deepening as he surveyed the battle plans before them.
Further down the table, the enigmatic LeBlanc sat with an amused smile playing on her lips. She rarely spoke unless necessary, but her influence in the empire was undeniable. Next to her stood Rell, the young iron-wielding warrior who had recently carved her own path into the ranks of Noxus. Unlike the others, her expression was one of barely contained frustration.
Across from them, Vladimir lounged with a casual smirk, his fingers idly tracing the rim of a goblet filled with a dark red liquid. His eyes gleamed with amusement, as if entertained by whatever political machinations were unfolding.
"The war in the west progresses," Swain said, his voice measured. "Demacia grows complacent. Their borders are secure, but their people grow too comfortable."
Darius grunted. "We should strike before they recover their strength."
LeBlanc chuckled softly. "And yet, there is something in the air, is there not? A shift. Something… unnatural."
Before anyone could respond, the same tremor that shook Demacia coursed through the room. The torches flickered, shadows stretching unnaturally against the stone walls. The war table trembled, goblets clattering against the surface.
Swain narrowed his glowing eyes. "This… is not normal."
As if to answer him, a blue circle of energy flared to life beneath them. The room erupted in a burst of blinding light—
And the leaders of Noxus vanished.

Mount Targon
Far above the world, where the stars touched the peak of the mountain, Soraka gazed down at the land below. Her celestial eyes shimmered as she watched the blue flashes erupt across Runeterra, one after another.
She closed her eyes, placing a hand over her heart. "So… it has begun."
