The city skyline of New York burned under a bruised twilight — the orange sun bleeding into the darkening sky like a wound that refused to heal. Stark Tower, once a beacon of hope and innovation, now stood battered, its sleek glass facade cracked and scarred. The world had changed. The hero who once lit up the skies with his flying armor and dazzling tech was gone.
And yet, in the shadow of his legacy, something new was stirring.
A pulse of light flickered deep beneath the rubble inside Stark Tower's underground lab. A faint hum, almost like a heartbeat, echoed through the cold concrete corridors. Suddenly, a sharp click pierced the silence, and a hidden door slid open with a hiss.
Inside the dim room, wires hung like tangled vines, screens flickered with static, and in the center, a figure lay motionless. A young woman — her features sharp, yet soft with the hint of inherited genius — slowly opened her eyes.
Her chest glowed with a soft, pulsating light — the unmistakable glow of an arc reactor embedded beneath her skin. The glow illuminated her face, revealing a mixture of confusion and determination.
"Where... am I?" she whispered, voice cracking as if waking from a dream she couldn't fully grasp.
She tried to move but pain shot through her limbs like electric fire. Memories crashed inside her mind — flashes of distant places, of battles, of people she barely recognized but somehow felt connected to. Names whispered in her ears: Stark, Tony, Avengers.
She sat up slowly, her fingertips brushing over the glowing arc reactor, warm and alive beneath her skin. Her breath quickened.
Outside, the world was crumbling.
Across the city, sirens wailed in the distance as a sudden surge of energy ripped the sky open. Cracks of blue and purple lightning fractured reality itself — a tear in the multiverse. Panic erupted in the streets; people ran screaming as buildings shimmered and flickered like mirages, caught between collapsing timelines.
In the ruins of the Avengers compound, Spider-Man swung into view, his suit torn, mask partially ripped, eyes wide with urgency.
"We've got another breach," he muttered through clenched teeth, landing hard beside Captain America, who stood firm, shield raised, scanning the sky.
Cap's jaw was tight, eyes steely but shadowed with doubt.
"This isn't just another attack," Steve said gravely. "It's something bigger — something tearing apart everything we fought to save."
From above, Thor descended, lightning crackling around his hammer. His usually playful grin was gone, replaced by grim determination.
"The skies themselves cry out in pain," he said, voice booming. "This is no mere battle — it is a war for the fate of all realities."
In a darkened corner, Black Widow slipped silently between the chaos, moving like a shadow. Her eyes scanned for threats, but something deeper gnawed at her — the feeling that this war was far from over.
Doctor Strange appeared in a swirl of glowing sigils, his cloak billowing, eyes glowing with mystic energy.
"I've sensed this coming for some time," he said. "The multiverse is unstable. A force is manipulating the timelines — one that could unravel existence itself."
And then came the quietest presence, but the most dangerous: Wanda Maximoff. Her eyes shimmered crimson, her magic flickering like wildfire.
"We don't have much time," she warned, voice low and urgent. "If this continues... if the rifts grow — nothing will survive."
Back in the lab, the young woman—the Stark sister—stood unsteadily. Her eyes met the flickering holo-projection of Tony Stark, frozen mid-speech, a ghost of the man she barely knew.
A voice echoed in her mind, a fragment of Tony's: "We leave legacies... not just for the world, but for the next generation to protect it."
She clenched her fists, feeling the weight of that legacy settle on her shoulders.
But then, her arc reactor flared suddenly — brighter, unstable — sending a shockwave through the room. Screens shattered. The floor trembled beneath her feet.
A voice boomed through the shattered lab's speakers:
"You are not ready. The multiverse will fall unless you choose your path."
Her vision blurred. In the haze, she glimpsed figures — familiar faces, heroes she would soon have to fight alongside... or against.
And then darkness.
