Chapter 10 – Shadows of The Past

Inside the damaged command center of Plumber HQ, tension thickened as the Avengers gathered around Ben Tennyson. The air was heavy with silence, only broken by the soft hum of the Omnitrix.
Ben slammed the device, twisting the dial. Emerald light erupted around him, transforming his human form into the sleek, bio-mechanical alien—Upgrade. His black-and-green frame merged seamlessly into the Plumber surveillance systems, data flooding his neural pathways as he hacked through encrypted signals.
His vision was a blur of data streams, energy signatures, and video feeds. Finally, the Omnitrix's interface displayed a location, glowing ominously.
"Klaue's facility," Ben murmured, his neon-green optics narrowing.
Natasha Romanoff stepped forward, her tone sharp. "Where?"
Tony Stark exhaled heavily at the mention of the name. "Ulysses Klaue. Fantastic. Because dealing with a crazed black-market Vibranium dealer is *exactly* how I wanted to spend my evening."
Thor, gripping Mjolnir tightly, looked toward Steve Rogers. "Then let us not waste time. This one will not bargain."
Steve nodded. "Avengers—let's move."
The Quinjet soared through the clouds, its engines roaring against the night sky. Below, Klaue's Vibranium facility loomed like a massive industrial fortress, its shipping containers stacked like mountains. Inside, the facility buzzed with illegal activity—workers smuggling, machines grinding, and crates stamped with the unmistakable mark: *VIBRANIUM.*
Deep within the warehouse, Klaue fidgeted nervously. His sweat-soaked hands gripped a datapad as he eyed his new client—Ultron.
The AI's sleek metallic frame gleamed under the dim warehouse lights, each movement deliberate and precise. Klaue forced a smile, masking the fear evident in his trembling voice.
"Look, uh… Ultron, my friend, you've got the Vibranium, right? So we're good, yeah? No need to complicate things."
Ultron tilted his head, his glowing red optics boring into Klaue. "You think I'm here for your… *friendship*?"
Klaue chuckled uneasily, stepping back. "W-Well, no, but, uh—"
Before he could finish, Ultron reached forward, grabbing Klaue's wrist and inspecting the branding seared into his skin—a mark of his black-market dealings.
Ultron's tone turned cold. "You are a parasite. Feeding on the chaos of others."
Klaue's unease turned to panic. "Wait, no—I can help you! I can—"
Ultron didn't let him finish.
With a sudden, brutal motion, he struck. Klaue crumpled to the ground, lifeless. The datapad fell from his hand, clattering on the cold concrete.
Ultron barely acknowledged the act, turning instead to oversee the final preparations for his next plan.
Then—
An explosion ripped through the facility's entrance.
The Avengers arrived, weapons ready.
Ben, already transformed into Buzzshock—a diminutive alien of pure electrical energy—buzzed in anticipation. Natasha rolled into cover, pistols raised and ready. Thor's lightning crackled as Mjolnir twirled in his grasp. Tony hovered overhead, his repulsors glowing. Steve raised his shield, his determined gaze fixed on Ultron.
"Alright, metal man," Tony growled, landing with a thud. "End of the line."
Ultron turned slowly, his expression unreadable. Then, with unsettling calm, he grinned. "Oh," he murmured. "I think you've only just begun."
Before the Avengers could move, a blur of silver darted through the battlefield—Pietro Maximoff. The speedster collided with Steve, sending him skidding across the floor.
Wanda followed close behind, her red mist swirling ominously as it filled the air, weaving illusions around the Avengers.
Thor halted mid-charge, his eyes glazing over as the mist clouded his mind. He stumbled back, gripping his head as visions overtook him.
He was back in Asgard.
But it wasn't the Asgard he knew. It was burning—its towers crumbling, its people screaming as a shadow loomed over the throne. Thor reached for Mjolnir, but the hammer disintegrated in his hand, leaving him powerless.
Natasha froze in place, her pistols trembling in her hands. The red mist pulled her into a haunting vision of the Red Room—the harsh training ground of her past. The faces of those she had hurt stared back at her, accusing and unrelenting.
Clint Barton collapsed to his knees, his bow slipping from his grasp. He was surrounded by the lifeless bodies of his family, their silence deafening, their faces void of blame—but filled with loss.
Steve staggered to his feet, gripping his shield tightly. But he wasn't in the facility anymore. He was back in the 1940s, a lone soldier on a battlefield surrounded by the corpses of his fallen comrades. Peggy's voice called out faintly, but when he turned, there was nothing but emptiness.
Ben and Tony, still unaffected, darted through the chaos, trying to snap the others out of their trances.
Buzzshock zipped toward Natasha, releasing a jolt of electricity near her, breaking the illusion. Natasha blinked, her vision clearing. She exhaled sharply, nodding to Ben in thanks.
Tony, meanwhile, blasted a repulsor beam toward Thor, disrupting Wanda's spell. Thor shook his head, regaining clarity. "Enough tricks!" he bellowed, lightning surging around him.
But before they could regroup, Wanda turned her attention to Bruce Banner.
Still in the Quinjet, Bruce had been monitoring the battle from afar, reluctant to join. But Wanda's mist seeped into his mind, pulling him into a nightmare of destruction and rage.
Bruce tensed, his hands trembling. His breath grew ragged, his pupils shrinking.
Then—he roared.
The Hulk exploded from the Quinjet, landing with earth-shattering force. His eyes burned with fury as he let out another deafening roar, charging toward friend and foe alike.
Tony muttered under his breath, "Oh, great. Not again."
Ben, now shifting into Humungousaur, braced himself as the Hulk barreled toward him. "Okay, big guy—let's dance."
Meanwhile, Albedo emerged from the shadows, his Ultimatrix glowing. He smirked coldly, activating Ultimate Humungousaur—his armored form towering over Ben's.
"Ready for a rematch?" Albedo sneered.
Ben didn't hesitate. "Bring it."
The two massive aliens clashed, their blows shaking the facility. Albedo's armored fists collided with Ben's brute strength, each impact echoing through the warehouse.
Thor swung Mjolnir, sending arcs of lightning toward Ultron, who dodged with mechanical precision. "You cannot stop evolution," Ultron taunted, deflecting the hammer with a vibranium-infused blade.
Natasha and Clint worked in tandem, taking down waves of Iron Legion drones as they closed in with Wanda.
Steve, snapping out of his nightmare, hurled his shield with pinpoint accuracy, knocking Pietro off course as the speedster charged again.
The battle raged, chaos engulfing the facility. Vibranium crates shattered, explosions ripping through the docks as the Avengers fought desperately to contain the threat.
But through it all, Ultron's smirk never wavered.
The Vibranium was gone—already sent away hours earlier.
And as Hulk's rampage grew uncontrollable, Wanda disappeared into the smoke, her laughter echoing hauntingly.
This battle was far from over.
