105 Hammer Droids 2.0

The Quinjet descended in near silence as it touched down on the overgrown grass flanking what appeared to be a recently abandoned weapons facility. According to the files from Zola’s archives and what remained of Hydra’s internal communication within SHIELD, this facility belonged to 'Hammer Industries' but had been repurposed as Hydra's weapon cache.

After Justin Hammer’s spectacular fall from grace and imprisonment for his collusion with Ivan Vanko at the Stark Expo, Hydra wasted no time in taking over the company from within. They repurposed its production lines, distribution networks, and R&D departments to churn out weapons and tech tailored to Hydra’s war efforts globally. What was once a flashy vanity project for Hammer to get into the Pentagon had become a hidden artery of terror that supplied warlords, insurgents, and rogue states indiscriminately.

Of all the factories, warehouses, and ghost companies still operating under the Hammer Industries banner, this one stood out like a sore thumb.

On paper, it was listed as Hammer’s flagship distribution centre. The blueprints submitted to federal regulators detailed a sprawling, high-tech weapons depot outfitted with advanced logistics, next-gen automation, and a classified "defence lab" that conveniently escaped further scrutiny due to national security red tape. It had cost nearly triple what any of Hammer’s other facilities had, with millions funnelled through layers of shadow accounting to hide how absurd the numbers were.

And yet, a flyover visual scan showed nothing to justify the expense.

From above, the facility looked unremarkable. A bland industrial shell. And that contradiction was exactly why they were here.

The Avengers agreed on one hypothesis: the surface-level warehouse was a front. The real secrets were buried underground. That would explain the inflated construction budgets and the suspicious lack of shipping activity logged in or out.

The Avengers disembarked to find a massive, featureless slab of blackened steel and reinforced alloy, squatting in the middle of a field like a forgotten bunker from a war no one won.

The grass was freshly trimmed. The pavement showed no signs of weathering. The outer walls had no vines, no dirt streaks, not even the stray leaves one might expect in spring. And yet, there wasn’t a single light. No motion sensors flicked on as they approached. No hum of electrical equipment. No flickering overhead bulbs or static from comms towers. No guards patrolled the perimeter. No service vehicles. No drones overhead. The main entrance was shut tight, as if sealed long ago. But the air still smelled like oil and ozone. Like something had been working here not long ago.

Around them, the trees stood still. The wind refused to blow. Not even insects dared to hum.

A dimly glowing Hammer Industries logo gleamed faintly above the doorway. It was the only splash of colour on an otherwise shadow-drenched building.

From their aerial scans and Tony’s infrared sweeps, they knew the compound held no signs of active life. No heat signatures, no energy readings beyond standby-level static. Everything pointed to an empty shell.

But empty things didn’t feel like this.

They approached the monolithic main entrance. It had no handles, no visible access panel, just seamless alloy designed to keep people out… or something in.

Without a word, Harry stepped forward, and with a wave of his hands, the door opened with a deep groan. The sound was terrible, metal grinding against metal in a slow, teeth-rattling scrape, echoing through the courtyard like the groan of some great beast roused from slumber. The gap widened inch by inch, revealing a yawning black void beyond. No light inside. Just a wide, empty corridor stretching into absolute darkness.

All of them stepped inside at once, to find stacks upon stacks of black weapon cases around them like silent sentinels, stretching up into the shadows above. Massive industrial racks crisscrossed the space in tight corridors, each shelf loaded with carefully organised, unmarked boxes.

Tony swept the room with his scanner. He shook his head. “No heat signatures. No electrical activity. Not even a mouse,” he muttered under his breath.

Harry raised his right hand as magic began to ripple from his fingertips. Tiny points of white light sparked to life in his palm like fireflies drawn to his presence. They swirled together into a sphere of silvery-white luminescence, slowly growing larger until it hovered just above his open hand, glowing like a miniature star.

With a flick of his wrist, Harry tossed it skyward.

The orb shot upward and exploded silently at the warehouse’s towering ceiling, releasing a cloud of radiant fragments. Tiny floating motes of light drifted outward in all directions. Like luminous pollen, they settled gently over everything: boxes, racks, crates, and corners.

The room was illuminated in ghostly silver light, allowing the Avengers to continue their investigation. 

The tension in the air began to ebb once the sight before them settled into something all too familiar: a warehouse full of guns. Deadly, but ordinary. There were no monsters waiting in the dark, no triggered defences or hostile ambushes, just row upon row of military-grade crates stacked upon themselves. With a silent nod from Steve, the team split off in different directions to look for the underground facility.

Natasha moved along the western wall, eyes scanning for seams, drafts, anything that might suggest a hidden doorway. Clint hoisted himself up a nearby rack, peering across the warehouse from above. Thor, unimpressed by human hiding spots, simply started knocking on the floor with Mjolnir like he was testing stonework in an ancient cave. Bruce drifted toward the control panels lining a far wall.

Harry stood at the centre, turning slowly, his magical senses reaching for something amiss. And everywhere the Avengers looked, they only found weapons. Crates stamped with Hammer Industries branding were filled with meticulously packed firearms from pistols to rocket launchers, with logistics tags and delivery schedules mapping out a vast grid of destinations across North America. Cities big and small. Coordinates ranging from inner-city warehouses to obscure rural outposts.

This wasn’t just a cache. It was a supply chain. Hydra had used Hammer Industries not simply to build weapons but to flood entire continents with them.

While the rest of the team continued to scour the warehouse floor, Tony had slipped away toward the narrow stairwell at the far end of the building, ascending to a small, glass-panelled office that overlooked the entire facility. With a blast from his gauntlets, the door hissed open.

Once inside, he directly approached the main console. “JARVIS, you’re up,” Tony muttered, plugging a portable drive into the system. The AI uploaded itself in a matter of seconds.

“Interface established, sir,” JARVIS confirmed. “Hammer Industries’ encryption is… insultingly weak.”

“Good. Let’s turn on the lights before someone stubs a toe.”

Across the warehouse, panels along the ceiling blinked awake one by one, bathing the entire compound in sterile white light. The rows of crates and towering shelves now looked less like the domain of horror and more like a hyper-militarised Costco.

But Tony wasn’t done.

“Alright, show me something juicy…” He scrolled through the access logs and mechanical schematics of the building. The elevator system, hidden beneath layers of obfuscated code, finally revealed itself tied not to a wall or panel, but to a massive hydraulic mechanism built directly into the warehouse floor.

“Bingo.”

He tapped the command.

Suddenly, the entire central platform of the warehouse rumbled. Forklifts shifted. A few crates teetered.

The Avengers froze as an enormous floor section at the heart of the facility began to descend like an enormous industrial stage.

Tony’s eyes widened. “Whoa, that’s not subtle,” he muttered, then quickly hit the kill switch, halting the platform’s descent with a metallic groan.

“I found our secret elevator, guys,” Tony’s voice echoed through the warehouse, tinged with amusement. “It just happens to be… you know, the floor.”

The team gathered atop the massive platform. Harry nodded to Tony, who hovered above them in his suit. Once everyone was in place, Tony restarted the descent, the ground beneath them shuddering as it began to lower into the earth.

It was quiet. Too quiet. So naturally, Tony broke the tension.

From the speakers of his suit came a gentle, jazzy tune, classic elevator music, complete with soft piano and faint saxophone.

Clint groaned audibly. “You’ve got to be kidding me.”

Steve just sighed and shook his head. Thor looked mildly confused. Natasha didn’t even flinch, just eye rolled.

 “Come on,” Tony said cheerfully, “We’re descending into a literal villain lair. Got to set the mood.”

The music echoed through the cavernous shaft as the Avengers slowly vanished into the shadows, heading toward whatever secrets lay buried beneath.

After descending for what felt like an eternity, the platform finally groaned to a halt with a heavy clang, locking into place deep beneath the surface. The light from the warehouse above had shrunk to a distant pinpoint, casting the team in a cone of fading white. Beyond them was nothing but suffocating darkness.

Harry raised his hand, ready to cast a Lumos but then froze.

A soft glow flickered in the dark.

Red.

One dot. Then another. And another.

Like embers flaring to life, they began popping up in every direction, first near them, then higher up, then deeper into the darkness ahead. And the lights kept growing in number. Dozens. Then hundreds.

Instinct took over before thought could. Harry cast a shimmering dome of golden light burst around the team just as the mechanical whirrrr of a Gatling gun spun to life.

BRRRRRRRTTTTTT!

The darkness erupted in muzzle flashes.

A storm of bullets slammed into the barrier from every direction, the sound deafening, like a hailstorm against tempered glass. Sparks danced across the surface of the dome as enchanted magic met unrelenting steel. The ground vibrated beneath their feet with the sheer ferocity of the onslaught.

Steve turned to Tony, his eyes already asking the question. Tony didn’t need to hear it. “JARVIS,” he said grimly, “lights.”

In an instant, the underground facility roared to life. Overhead halogens flickered, buzzed, then fully blazed on—one by one, row by row—stretching out endlessly across the cavernous chamber.

The shadows peeled back to reveal a nightmare. Surrounding them on all sides, standing shoulder to shoulder in tightly packed formation, was an army of hundreds, maybe thousands of Hammer Droids. But these were not the clunky, unstable machines from the Stark Expo. These were newer. Meaner. Deadlier.

Each unit stood over seven feet tall, its armor plates sleeker, matte black and gunmetal gray. Their limbs were bulky, reinforced with thick hydraulics and exposed servos that hissed and clicked in unison. Mounted along their spines and forearms were modular weapons, each one engineered for slaughter.

But it was their faces that chilled the room.

Where once there had been blank, humanoid faceplates, these droids now bore skeletal visors—sharp, angular, predatory. Each one pulsed with twin red optics, glowing like the eyes of the damned. And all of them were staring directly at the Avengers.

As the relentless barrage of bullets continued to ricochet off the golden barrier, several of the droid in the front line halted their fire. From the inner compartments of their arms two whip-like cables unfurled from each limb. The air vibrated as electricity surged along the length of the whips, lighting them up in flickering arcs of blue-white energy.

The whips lashed at the dome mercilessly. Each impact exploded in a burst of lightning and golden ripples. The dome flared with every blow, glowing brighter and thinner, its smooth curve fracturing under the pressure of repeated strikes. Thin cracks of light spiderwebbed across its surface. Harry, though, was unperturbed. He knew that no matter how relentless these attacks were, they wouldn’t break his shield.

Clint glanced around the golden barrier as the constant sound of metal whips and bullets crashed against the magical dome like a war drum. Inside the dome, they were untouchable. Outside, they’d be torn to shreds. But none of them looked concerned.

“So… how exactly do we get out of this?” he asked dryly, not a trace of panic in his voice. Despite the storm raging just inches away, the team chuckled. This wasn’t their first time being outnumbered. It wouldn’t be the last.

Natasha pulled out her pistols and checked the magazines anyway, though her face was more annoyed than anxious. “Should’ve packed grenade launchers,” she muttered. “Or a tank.”

“These will barely tickle them,” Clint added, giving his bow a sceptical look.

Thor smiled, stepping forward as the first traces of lightning began to arc across his shoulders. The soft crackle of electricity danced in the air. “Lady Potter, Barton, Captain,” he said grandly, lifting Mjolnir. “Allow the heavy hitters to stretch their arms today.”

Bruce cracked his neck as his skin began to ripple and shift, his eyes glowing a familiar angry green.

Tony rolled his neck with a click and brought his arms up, repulsors glowing. “Looks like this one’s all sparks and smash. Cap, Romanoff, Legolas, you’re benched.”

Steve gave a wry smirk. “I won’t complain.”

“Don’t break the place too much,” Natasha added, holstering her pistols. “We still need to loot it afterwards.”

Harry extended his hands, and Steve, Natasha, and Clint reached for him without hesitation. With a crack of displaced air, they vanished, reappearing a split second later inside the Quinjet.

The moment their boots hit the floor, the golden dome below shattered like glass under a hammer.

And hell was unleashed.

Tony rocketed upward. He strafed the swarm of droids and started blasting the droids with his repulsor beams. Each shot punched clean through armoured skulls and sent molten circuitry raining down.

Thor let out a triumphant roar as one of the whip-wielding droids lashed at him. He caught the electric tendrils mid-air with a crackle of lightning dancing across his fingers, yanked the droid toward him and brought Mjolnir down like divine judgment. The machine exploded into a shower of twisted shrapnel.

Then the Hulk roared.

He barreled into the sea of droids like a wrecking ball through glass, arms wide and unrelenting. Metal tore, sparks flew, and limbs were flung in every direction. He didn’t pause. Didn’t slow. He smashed.

Harry reappeared on the battlefield, robes whipping behind him like a shadow stitched to fire.

His eyes glowed green as he swept a hand across the torn floor. The broken remains of shattered Hammer-Droids trembled, rising from the dirt with an eerie creak of metal bending to new purpose.

They reassembled golems of steel and smoke, fused by transfiguration. Glowing eyes sparked to life. And with a wave from Harry, they turned on their former comrades shredding them into pieces.

The army of droids advanced like a tidal wave. Rows upon rows of humanoid machines filled the subterranean expanse. Electricity danced along the whips of the frontliners; behind them, shoulder-mounted guns rose from backs like unfolding insect wings.

But the four Avengers stood unmoved. A wizard, a genius, a god, and a force of nature. The storm was coming, and they were the storm.

Iron Man surged forward like a missile, weaving between lines of enemy fire with dancer-like grace, each flick of his hands unleashing blasts that punched through skull casings, disabling command cores in neat, glowing bursts.

Below, Hulk let out a bone-rattling roar that drowned out even the gunfire.

He charged.

The floor trembled under his steps. Then he leapt over the line of droids, crashing into another with the force of a meteor. Steel shattered like porcelain beneath his fists. He grabbed two droids by their legs and slammed them together with a sickening crunch, using them like maces to batter a third. Sparks and oil sprayed in every direction as Hulk plowed forward.

Thor followed close behind, Mjolnir already spinning at his side, a low whine building as static electricity flooded the air. He threw the hammer with a battle cry and the weapon flew in a straight, screaming line, carving a path through the army. When it struck a central droid, the explosion that followed ripped through a dozen more. Thor summoned the hammer back to his hand and took to the air, trailing bolts of blue lightning in his wake. Droids fell like trees in a storm as he rained thunder down upon them, Mjolnir crashing and crackling with every swing.

Harry, conjured jagged spears of steel from the debris around him and sent them flying like arrows into the cores of the droids. With a flick of his wand, vines of glowing runes erupted from the floor, entangling a pack of droids mid-charge and tightening until their limbs snapped like twigs. Then, with a shout of “Incendio Maxima!”, he engulfed the entire knot in a wave of enchanted flame.

Above, Tony’s voice crackled through the comms. “Left flank, Thor! Big boys incoming!”

From one of the shadowed tunnels emerged a new class of Hammer Droids larger, bulkier, with rotating cannons for arms and armor thick enough to deflect even repulsors.

“Let me,” Thor growled.

He landed directly in front of the juggernauts, hammer raised.

They opened fire, but Thor twirled Mjolnir, creating a vortex of pure lightning that incinerated the rounds mid-air. Then he charged, dodging between the lumbering behemoths. Each blow from the hammer sent tremors through the chamber. One droid lost its arm; another crumpled as its chest plate was crushed inward. Thor spun once, twice then unleashed a bolt of lightning so fierce it blew out the central generator of four droids at once, leaving behind only smoking husks.

Meanwhile, Tony zipped through the roof of the underground facility, weaving between gantries and catwalks. He fired down on the horde, picking off any stragglers that slipped past Hulk and Thor. But one particularly agile droid leapt up, magnetic claws attaching to his leg.

“Alright, rude,” Tony muttered and then ejected a micro-missile straight into the droid’s face. It exploded mid-cling, sending Tony into a barrel roll before he righted himself and dived back into the chaos.

On the ground, Harry raised both arms. The remnants of destroyed droids began to shake, then rise. With magic binding metal, he created more golems from the battlefield’s debris. These magical machines turned with perfect obedience, pouncing on the nearest droids and ripping them limb from limb.

In the middle of it all, Hulk was losing himself in the rhythm. He crushed a droid’s head in his palm, then swung its body like a club. Another leapt onto his back, he simply slammed himself backward into a support beam, caving both it and the droid in. A pair of droids aimed their arm-mounted whips at him but Hulk grabbed both, yanked them forward, and smashed their heads together like cymbals.

“Big guy’s doing fine,” Tony quipped, landing beside Harry as he overcharged his repulsors for a blast that vaporized three droids in a row.

Thor landed beside them, armor scorched, Mjolnir humming in his grip. “A glorious challenge. But I believe we are winning.”

The team advanced as one, cutting deeper into the swarm. With every step, they fought as a single, lethal unit. Droids kept coming, slower now, And one by one, they fell.

Until nothing remained but smoke, sparks, and the silence of a failed horde of machines.

As the final droid collapsed in a heap of sparking metal and scorched wires, a strange, synchronized sound echoed across the underground chamber.

Beep.

Then another.

Beep-beep.

Tony’s eyes snapped to the nearest fallen unit and immediately saw the glowing red light pulsing in its chest cavity like a countdown heart.

“Oh, come on,” Tony groaned, scanning the rest of the battlefield. “Self-destruct protocol. Of course. Because why wouldn’t the killer robot army have a failsafe that kills everyone again?”

The remaining Avengers gathered in close as Harry drew a tight arc through the air with his wand and shouted, “Protego Maxima!”

A golden dome erupted outward, it anchored into the cracked stone beneath them, locking into place just as the first explosion hit.

BOOM.

The world outside the dome ignited in violent chaos.

The chain reaction surged across the battlefield like a rising sun of destruction. One by one, the droids detonated in massive bursts of red-hot fire and shockwave energy. The underground facility trembled, pillars cracking and overhead steel creaking dangerously. Chunks of ceiling began to fall. The very earth above them groaned in agony.

The shockwave pounded against them from every direction. Dust filled the air. Lights above shattered. Then, with a final deep CRACK, the cavern’s roof caved in.

Massive slabs of rock and steel crashed down, slamming onto the surface of the shield with thunderous force.

“Hey, big guy…” Harry said gently.

He turned to face Hulk and lifted his wand again.

“Sopor serenus,” he whispered. Soft ribbons of blue light spiralled from the wand and encircled the green behemoth. They shimmered like a lullaby given shape, weaving through the dust and firelight.

The Hulk’s breathing slowed. His massive shoulders relaxed. The snarl faded from his lips. Hulk’s form began to shrink. Bones cracking, muscles retracting, skin lightening from green to pink. Within moments, Bruce Banner stood in the ruin-strewn battlefield, hunched and shirtless.

He sank to one knee, breathing heavily. Harry immediately conjured a soft shirt and offered it to Bruce. Bruce nodded in thanks, too exhausted to speak. He pulled the shirt over his head and sat down among the wreckage.

Harry closed his eyes and placed his hand flat against the broken floor. Magic surged through him like a tide returning to shore. The shattered stone beneath their feet began to tremble then slowly, deliberately, it rose.

The ground itself obeyed Harry’s will, carrying the four Avengers upward like an. They ascended through. As they breached the surface, the ruined roof collapsed outward to make way. The slab of floor carrying the Avengers lifted into the air like a floating platform, drifting over debris and broken scaffolding until it gently came to rest on solid ground.

Waiting nearby was a fleet of SHIELD agents and scientists, led by Agent Coulson. Their heads turned as the Avengers rose from the earth like myth given form.

Coulson walked forward. “I’m guessing by the seismic readings and sudden appearance of a crater that things didn’t go smoothly?”

“You could say that,” Tony replied, stepping off the platform with a huff.

As SHIELD operatives fanned out, Harry and the others made their way to the Quinjet. The jet’s ramp lowered as they approached. Nobody spoke as they stepped inside. The Quinjet lifted off, rising over the battlefield, past the SHIELD teams moving like ants through the wreckage.

Once he was comfortable in his seat, Harry dialled Pepper. It rang once.

“I’m sleeping, Harry,” Pepper mumbled groggily as she picked up.

Harry didn’t miss a beat. “Release the Hammer Industries files. All of it. Every contract, payment trail, and weapons manifest. Dump it to the press, international watchdogs, and our usual whistleblower channels.”

A long pause.

“Can’t we do that tomorrow morning?” she asked, voice muffled as she rolled onto her other side. “Once I get to the office.”

“No. It has to be now,” Harry replied. “If we hit them before the opening bell, their stock will nosedive before their lawyers finish their first cup of coffee. By the time the board tries damage control, they’ll be radioactive.”

With a groggy sigh, Pepper dragged herself out of bed and padded toward the kitchen, phone tucked between her shoulder and ear. “You owe me for this, Potter,” she muttered.

“Hey, I’m tanking Hammer Industries’ stock price into the earth’s mantle and staging a hostile takeover through Marauders Capital as we speak. Once we’ve gutted their value and scooped up the pieces, I’ll pass it all over to Stark Industries, no negotiation, no inflated buyout. Just a gift-wrapped billion-dollar company without the criminal baggage.”

Pepper snorted. “You realise that’s insider trading, right?”

“That’s why I’m letting you do the legal paperwork,” Harry answered.

 “That’s just more work,” Pepper groaned, followed by the familiar sound of the coffee machine sputtering to life in the background.

Harry chuckled. “Come on, Pepper. I think this move is going to push Stark Industries into the trillion-dollar club in five years, tops.”

“Bold claim,” she replied, clearly unimpressed.

“I got to see it firsthand,” Harry said, leaning back in his seat on the Quinjet. “Their robotics division is terrifyingly efficient. They built it off Tony’s and Vanko’s old blueprints, but refined with Hydra’s obsession for scale. It's better than anything else on the market. And now, it’s ours.”

There was a pause. He couldn’t see her expression, but he could practically feel her rolling her eyes through the phone.

“Alright, whatever,” Pepper sighed. “I’ve got work to do and make sure Tony actually shows up for the MIT Innovation Symposium.”

The line went dead before Harry could respond.

Across the Quinjet, Tony groaned audibly. “Do I have to? I’m in the middle of cracking the Ultron Matrix.”

“You need to get out of the tower once in a while,” Natasha chimed in. “Maybe talking to a bunch of bright-eyed engineers will shake loose the brilliance you clearly think you’re missing.”

Tony shot her a look. “I don’t need their ideas. I need quiet.”

“Maybe the kids will debug it faster,” Clint quipped from his seat. “Or at least tell you when your evil robot overlord plan sounds too much like a Bond villain pitch.”

“Not evil,” Tony muttered, fingers twitching like he was already coding in his head. “It’s a peacekeeping program.”

“I think VERONICA does a better job at peace-keeping than your failure of an Ultron Program,” Bruce said gently, arching an eyebrow.

Tony ignored the jab and turned toward Bruce. “Well, if I’m being forced to suffer through this MIT event, so are you, big guy.”

Bruce blinked. “I wasn’t even invited.”

“Doesn’t matter. We’ll both go. Tag team. We suffer together. Brain trust solidarity.”

Harry chuckled quietly as he looked out the Quinjet window, as the stars were just starting to fade behind the rising dawn.
