Ben Tennyson in the MCU

INT. HELICARRIER – MESS HALL

Hill remained seated, watching as Ben's figure disappeared down the corridor. Their conversation had been brief, yet it had given her much to consider. The idea that Ben was from a parallel universe was absurd—too far-fetched to be true. And yet, she couldn't entirely dismiss it. He hadn't provided proof, but his tone and body language suggested he had a way to do so—just not yet.

Her impression of Tennyson so far? Pragmatic. Intelligent. Fiercely determined. Yet, despite his confidence, there was something else—an undercurrent of inexperience. He was still finding his footing, learning as he went. For now, the best course of action was to observe.

She had already placed Tennyson in the same category as Thor and the Hulk—powerful individuals with unknown limits, and, more importantly, not from this world. The array of transformations he had revealed—Wildmutt, Rath, Diamondhead, XLR8, Big Chill, Jetray, Brainstorm, Swampfire as he called them. Each hinted at a staggering potential. And she suspected there were others. Unrevealed and possibly even more formidable.

Her comms buzzed in her ear, and Fury's voice came through, sharp and commanding.

"Hill, I need you back on the bridge. ASAP."

She responded without hesitation. "Copy that."

The call ended abruptly, and Hill sighed. She could tell Fury wasn't in the best mood. Shaking her head, she rose from her seat and headed back to her post.

INT. HELICARRIER – HALLWAY

Ben strode toward the lab, his mind racing. So far, things had been going according to plan—more or less. SHIELD hadn't made any major moves against him, despite the leak of his secret identity. That leak had been intentional—a way to test the waters. Maintaining a long-term secret identity had never been his goal. It would only make things more complicated down the line.

Remaining in the shadows, influencing events from behind the scenes, was still possible. But this world was in a much earlier stage than he had anticipated. The Fantastic Four hadn't gained their abilities. Spider-Man was just an eleven-year-old kid. The X-Men and other mutants were practically nonexistent in the public eye.

For now, mutants were seen as rare genetic anomalies—people with an extra appendage or minor physical mutations. No documented reports of true superhuman abilities existed, at least none that weren't buried deep in classified SHIELD files. Even scouring the internet had turned up next to nothing. This Marvel Universe was just beginning.

Ben's thoughts drifted to his unrevealed transformations—Goop and Upgrade. Keeping them under wraps for now was wise, a strategic advantage. And then there was the Frost Giant and Asgardian DNA he'd collected, a testament to his adaptability and foresight.

If figures like Spider-Man and the Fantastic Four hadn't yet emerged, then Ben had an opportunity—a chance to establish himself as a key player in ushering in the New Age of Heroes. He was determined to make the most of it, to carve out a place not just as a hero, but as a leader.

Then—

Raised voices.

His thoughts were abruptly shattered by the sound of heated arguing echoing from the lab, an unsettling cacophony that pierced through the usual hum of machinery.

Ben frowned, his brow furrowing deeply.

What the hell is going on?

As he approached the heavy door, the voices crescendoed, a mix of frustration and urgency that made his heart race.

When he finally stepped inside, the scene before him was chaotic—Fury, Thor, Natasha, Stark, and Steve were caught in a fervent debate, their faces flushed with intensity and palpable tension.

INT. HELICARRIER – LAB

"HEY! What the hell is going on?!"

Ben's voice sliced through the din like a blade, commanding immediate silence. The room fell still as all eyes turned toward him, surprise etched on their features.

His gaze darted around, taking in the frantic energy of the room before landing on Bruce. Ben's breath caught in his throat as he noticed Banner's right hand hovering perilously close to Loki's scepter, the artifact pulsating with a faint, eerie glow that seemed to throb in time with the tension.

Ben's expression darkened, a sense of dread washing over him.

Something is wrong.

"Bruce. Step away from the scepter. Now."

Banner blinked, as if awakening from a deep trance. Slowly, his gaze drifted downward, and he finally registered the dangerous proximity of his hand to the weapon, his expression shifting from confusion to horror.

A chilling silence enveloped the room, the air thick with unspoken fears. Everyone else followed his gaze, their eyes widening as the scepter gleamed ominously, a sinister warning in its glow.

Thor was the first to break the suffocating silence, his voice booming with authority. "This is one of Loki's tricks. He means to ensnare us!"

Before Ben could process Thor's words, a series of beeps interrupted the tension. His bracelet and computer chirped in unison, an urgent signal demanding his attention.

Instinctively, he turned his wrist, and a holographic feed flickered to life, a global map materializing before him. The map zoomed in, revealing multiple hotspots lighting up with alarming speed.

Everyone's eyes widened in horror, realization dawning.

"Oh my God—"

EXT. HELICARRIER – SKY ABOVE THE OCEAN

Barton steadied himself, pulling back his bowstring with practiced precision. The air was thick with anticipation.

With a swift release, the arrow flew from his fingertips.

BOOM!

The arrow struck true, and in a blinding flash, an engine erupted in a violent explosion—ripped clean off the Helicarrier, sending debris spiraling into the sky.

INT. HELICARRIER – LAB

Suddenly, a massive explosion tore through the Helicarrier, the shockwave crashing through the lab like a tsunami of chaos. Stark, Fury, and Steve were flung backward, their bodies colliding with the walls, the force of the blast sending them sprawling.

Ben barely had time to react as the blastwave surged forward, hurling him through the lab doors. He collided painfully with the steel guardrail, the impact jarring his bones and sending him tumbling to the second floor.

His back slammed into the unforgiving metal floor, the shock rattling his skull and leaving him momentarily dazed. The world spun around him, a dizzying blur of colors and sounds.

Somewhere in the distance, alarms blared, their wailing a stark reminder of the chaos unfolding.

The battle had begun.

INT. BANNER'S LAB

Fury sits up, clutching his ribs. He puts on his EARPIECE.

Nick Fury's voice cut through the chaos. "Hill?!"

The helicarrier bridge was a scene of pandemonium. Emergency alarms blared, fire extinguishers sprang to life, and agents scrambled for their positions and armaments. In the midst of the upheaval, Agent Maria Hill maintained her composure, striving to keep the bridge as calm as possible.

"Turn up that engine!" she commanded. "Number 3 engine is down! Can we get a run in?" She hurried over to an agent who was glued to a monitor. "Talk to me," she urged.

The agent, known for his penchant for playing Galaga when things were quiet, pointed to the screen. "Turbine's loose. Mostly intact, but it's impossible to get out there and make repairs while we're in the air."

Hill's expression hardened. "We lose one more engine, we won't be in the air for long. Somebody's got to get inside and patch that engine."

EXT. HELICARRIER DECK � DAY

Barton leads his men into the air ducts of the ship. They rappel down into a corridor.

Meanwhile, in Banner's lab, Nick Fury's voice echoed through the comms. "Stark! You copy that?!"

Tony's voice crackled back, decisive and focused. "I'm on it!"

Fury didn't waste a moment. "Coulson! Initiate official lockdown in the detention section, then get to the armory! Move out!"

Back on the helicarrier bridge, Agent Coulson sprinted out, his mission clear.

In the lower equipment room of the carrier, Natasha glanced over at Banner. He was breathing heavily, having landed hard. His grip on the grated floor was tight as he fought for control, his eyes glowing an ominous green, his face taut with intensity.

Quietly, almost as if reassuring herself, she whispered, "I'm okay. We're okay, right?"

Ben groaned, trying to get his bearings, but his head throbbing from the impact. His Matte-black compression shirt with hexagonal texture absorbed most of the impact.

Both his pants and top were made out of Carbon-Neoweave Fabric: A graphene-infused polymer composite (lightweight, slash-resistant, breathable).

A long with Impact Gel Lining: Shock-absorbing pads at joints, ribs, and spine (activated on impact, like *Arkham*'s armor system).

However, he was wearing his helmet when the explosion occurred and he'd barely managed to adjust his fall to protect his head.

"Tennyson? You alright?"

Steve's voice cut through the ringing, and then—strong hands grabbed Ben, hauling him up.

"Come on, shake it off," Steve urged.

Ben staggered, head pounding. He felt Steve's grip tighten on his face, forcing eye contact.

"Deep breaths. Focus. Come on."

Ben gritted his teeth, forcing himself to concentrate. His blurry vision slowly began to clear.

"Yeah… yeah, I'm good," Ben muttered, though his ears were still ringing.

Steve nodded, satisfied.

"Good. Suit up. Stark and I will handle the engine. You find Natasha and the others."

Ben nodded, forcing himself to stand. "Don't worry, I got this. Go."

Steve gave him a curt nod before limping away, as he ran to support Tony at the damaged engine.

Then he turned and ran.

Ben exhaled sharply, shaking his head as his focus returned. A sharp pain shot through his skull—his first time experiencing an explosion up close. Something told him it wouldn't be the last. He pushed through the pain.

Ben winced as another wave of pain pulsed through his head. Gritting his teeth, he forced himself forward, bending his knees before launching himself upward—his boots' hydraulic springs propelling him nearly twenty feet in the air. He landed on the upper platform, gripping the guardrail for balance before vaulting over and rushing back into the lab to grab his equipment.

The room was a mess—shattered glass, overturned workstations, and the gaping hole in the floor where the explosion had torn through the structure. His helmet and jacket were near his workstation, miraculously intact. He spotted his gauntlets half-buried under debris.

Ben moved swiftly, grabbing his jacket first and slipping it on. Then, he reached for his helmet—only to pause as a voice cut through the blaring alarms.

"I've been looking forward to chatting with you properly for quite some time, Mr. Tennyson."

Ben's fingers tightened around his helmet before he slowly turned toward the voice.

Loki stood just a few feet away, his scepter in hand, gazing down into the hole where Natasha and Bruce had fallen. A pleased smirk graced his lips. "A shame you weren't here to witness the little show your new allies put on for me."

Ben immediately linked his comms through his helmet, ensuring everyone on the Helicarrier could hear the conversation. Loki, unaware of this, continued speaking.

"I must say, you arrived late to the party." He sighed dramatically, his fingers idly tracing the curve of his scepter.

Ben finished securing his helmet before crossing his arms. "Aren't you supposed to be in your cell? Let me guess—it's just an illusion. Call me impressed you're even able to fake your thermal and pulse readings."

INT. HELICARRIER BRIDGE

Maria Hill stood alone, gripping the console as she struggled to stabilize the situation. Red warning lights bathed the bridge in an eerie glow, alarms blaring as crew members scrambled at their stations.

The Helicarrier was in crisis.

Losing one engine had thrown the entire ship into chaos. They were listing, altitude dropping, and unless Stark and Rogers could get things under control, they were looking at a catastrophic failure.

Then, Loki's voice crackled through the comms.

A chilling silence followed as the words sank in.

On the bridge, Hill's stomach twisted as she frantically pulled up the security feed. Loki was still sitting in his cell—or so it seemed. A quick thermal scan confirmed the horrifying truth: Just an illusion. There was clearly a thermal reading but, Ben wasn't in the room and there was only one place Hill could think off where this conversation was taking place.

She inhaled sharply, fingers flying across the console. Loki had never been contained.

Fury, still en route to the bridge, stopped mid-stride, his expression darkening. His mind raced—if Loki had been free this whole time, then everything they thought they had under control was a lie. Clenching his jaw, he picked up the pace.

Out on the port side, Steve barely broke his stride but his grip on the shield tightened. He exchanged a quick glance with Tony, both men processing the implications.

Tony, half-suited up, froze for just a second before muttering under his breath. "Oh, great. Magic bullshit." His mind immediately shifted to worst-case scenarios—if Loki had been roaming free, who else had he manipulated?

INT. HELICARRIER – LOWER DECK

Natasha's breath hitched as she heard Ben's words through her comm. Her pulse quickened—not from fear, but from cold, sharp realization. Loki had never been locked up.

She lifted her head slightly, her gaze locking onto Loki, who stood above her, smiling. He knew that she knew. And he was enjoying it.

Beside her, Bruce's breathing grew more erratic, his fingers twitching against the metal floor. He was fighting it, but barely.

Loki chuckled, amused by the unfolding chaos. "Now, let's see how long you can keep up the act, Doctor."

Natasha gritted her teeth, her leg trapped under a heavy piece of debris. She wasn't badly injured, but she wasn't getting out of this without help.

Bruce knelt beside her, his hands shaking slightly, his breathing uneven. She could see the tension in his body—the barely restrained rage.

"Banner, stay with me," she murmured, trying to keep him calm.

Then, they heard the voice.

Loki.

Standing directly above them.

The god of mischief peered down into the hole, his expression one of detached amusement. "Ah, Romanoff. A most unfortunate position you've found yourself in." His gaze shifted to Banner, a knowing glint in his eyes. "And the good doctor… trying so hard to suppress his true nature."

Natasha clenched her jaw. "You son of a—"

Loki merely chuckled. "Now, now. No need for hostility. I'm merely enjoying the spectacle."

Loki's scepter hums softly as he stood up and approaches Ben, its glow pulsing like a predator sensing prey. Ben's Omnitrix responds with a defensive chime, its green light flickering.

"You're not just some mortal playing hero, are you, Mr. Tennyson?" Loki says, a smirk playing on his lips. "I've sensed it since we met—a wrongness in the air. Like a song out of tune."

Ben tenses, his hand hovering over the Omnitrix. Loki chuckles, twirling the scepter.

"Oh, don't feel so surprised," Loki continues. "The All-Father taught me to sense disruptions in Yggdrasil's branches… and you, little mortal, are a splinter wedged deep in its roots."

"Yeah? Well, pull me out, and you'll regret it," Ben retorts, his voice steady.

Loki tilts his head, feigning innocence.

"Regret? Hardly," Loki muses. "Men like you are opportunities. A wanderer from beyond the stars, beyond...this reality wielding a device even my Father couldn't fathom… What price would you pay to return home?"

Ben's jaw tightens, struck by Loki's words.

"Well, I don't necessarily want to go back. And you're going to find out just how stubborn this thing off my wrist. You're pettiness," Ben declares firmly. A playing smirk under his helmet.

Loki laughs softly.

"Such fire! But you misunderstand," Loki says. "I don't want your toy… I want to see what happens when you break."

The scepter's glow flares, and for a moment, Ben's shadow twists unnaturally—stretching into an inhuman silhouette. Loki's grin turns feral.

"When your walls crumble and your allies forsake you… then we'll chat properly," Loki finishes, his eyes gleaming.

The dim emergency lights flickered as Bruce clenched his fists, his face contorted in struggle. The rage boiled beneath his skin, his features beginning to shift, muscles tightening as his breathing grew uneven.

Across from him, Natasha gritted her teeth, dragging herself free from the debris trapping her leg. Despite the pain, her voice remained steady, urgent.

"Bruce... you gotta fight it. This is exactly what Loki wants. Listen to me—we're gonna be okay."

Standing tall, his hands behind his back, fingers working discreetly on the Omnitrix. Ben counted in his head, preparing to select a heavy hitter. His voice cut through the tension.

"You're not going to win, we know where the Tesseract is. This ends now—peacefully, if you stop here."

Loki smirked, amusement dancing in his cold eyes. "Oh, I know. But I believe you have... bigger problems, don't you?"

Below them, two SHIELD agents rushed toward Natasha's position, but she snapped her head up and waved them off with a sharp, furious gesture. They hesitated before retreating, recognizing the volatility of the situation.

She turned back to Banner, her voice softer now. "We're gonna be okay. I swear on my life, I will get you out of this. You will walk away, and never—"

Banner let out a rough chuckle, his voice shifting—deeper, guttural. "Your life?"

Another explosion rocked the carrier. The lights flickered out. And as Bruce lifted his head toward her, the transformation overtook him.

"Bruce," Natasha whispered, fear creeping into her voice.

Loki stood, stretching leisurely before glancing back at Ben.

"I'd love to stay and watch the show," he mused, "but I'm afraid I have a world to conquer."

As he turned to leave, Ben spoke again.

"Hey. Aren't you going to say goodbye to your big brother?"

Loki barely had time to react before Ben suddenly ducked as a blur of silver and blue shot past. Mjölnir passing over head as Ben slide down towards the hole and into the lower equipment room.

The enchanted hammer hurtled toward Loki's skull—only for him to lift his scepter at the last second, deflecting the strike. The impact sent a crackling shockwave through the room as Thor limped into view, his face bruised, his fury unmistakable. He summoned Mjölnir back into his grasp, gripping it tightly.

"Loki, this game of yours ends here," Thor's voice boomed, his stance unwavering despite his injuries.

Loki only sighed, tilting his head. "Oh, brother... you never learn, do you?"

A flash of blue energy erupted from Loki's scepter, hurtling toward Thor.

A deafening, inhuman roar filled the space, rattling the walls. The Hulk had arrived.

Ben landed lightly behind the green behemoth, his gaze traveling up the massive frame towering over him.

"Okay... Hulk?"

The Hulk turned, nostrils flaring as he glared down at yet another puny human daring to stand behind him.

Ben exhaled slowly, raising his hands in a non-threatening gesture. "Hey, we haven't met yet. I'm Ben Tennyson. Big fan—though, uh, this isn't really how I imagined we'd meet."

The Hulk narrowed his eyes, barely registering the words. Above them, the distant sounds of battle—Thor and Loki clashing—echoed through the carrier.

Natasha, still crouched behind Hulk, tensed. She had been ready to run, but now she stood frozen, watching.

Ben took a careful step forward, then another, keeping his voice even. "Let's take this nice and easy, yeah?"

Hulk didn't move. His breathing was ragged, shoulders heaving. But he hadn't attacked.

Yet.

Natasha shifted slightly. Hulk's ear twitched. Ben clocked the movement immediately.

This could go very, very badly.
