As a Symbiote in Marvel multiverse

**Earth-199999**

Steve adjusted his gloves as he stood inside the abandoned airport, exhaling slowly. Behind him, the others were suiting up, preparing for what was about to happen. They already knew the plan. Now, it was time to execute it.

But just then Tony's voice echoed through the air, calling Steve out.

With a nod to his allies, he stepped forward alone.

As soon as Steve stepped outside, he heard the familiar hum of repulsors as two armored figures descended from the sky, landing a few feet away.

Tony Stark and James Rhodes descended from the sky, landing a few feet in front of him in their Iron Man and War Machine suits.

"Steve," Tony started as his helmat opened, "I'm trying to give you an out here. Ross gave us 72 hours. That was yesterday. I don't want to do this, but you're forcing my hand."

Steve remained calm with his shield strapped to his arm. "Tony, listen. Someone's pulling the strings. The doctor, the psychiatrist, he's behind all this. He's trying to awaken more Winter Soldiers. This isn't just about Bucky."

Tony exhaled while shaking his head. "Tell it to Ross yourself. Haaa... Listen, We've all got our reasons, Cap. But you don't get to decide for everyone. We keep doing things your way, and the Avengers fall apart. You're splitting us up, not me."

Steve's jaw tightened, and before he could respond, Natasha Romanoff walked into view, standing beside Tony. "Steve… this is your last chance. Come in willingly."

Steve clenched his jaw. "I can't do that, Nat."

Tony exhaled and his patience is running out. "Alright. Have it your way." He looked up and gave a simple order. "Underoos."

A sudden thwip cut through the air as Steve's shield was yanked from his arm by a webline. Before he could react, another web shot out, wrapping around his hands and pinning them to his sides.

A figure in red and blue flipped gracefully through the air, landing on top of a nearby jet. "Hey, Cap!" Peter called out, giving a small wave.

Steve raised an eyebrow. "Seriously? Peter?"

The young masked hero froze for a second before shaking his head quickly. "Uh—no, no, definitely not Peter! Wrong guy!"

While Peter of this universe was confused how Cap knew about him, the others weren't. Thanks to the time spent with the Peter from another universe, the Avengers had already looked into their own world's Peter Parker. He had potential, but at the time, he wasn't powerful enough to be a concern. Now, he was standing in front of them, in a Stark-made suit, trying to take down Captain America.

Steve narrowed his eyes and flexed his arms, tearing the webbing off with raw strength. "That was a mistake, kid."

Before Spider-Man could react, a tiny figure appeared on Steve's shield and punched him in the face.

Peter yelped as he lost balance, his grip on the shield loosening. Scott Lang quickly expanded back to normal size, grabbing the shield midair and running toward Steve.

"Here you go, Cap!" Scott grinned.

Steve took the shield from Scott and strapped it onto his arm."We don't have time for this."

Peter took a step back after recovering. "Okay, that was actually pretty cool."

Tony sighed and motioned toward Spider-Man. "Alright, Underoos, forget Cap. Go after Barnes. Scanner says they're on the top floor."

Spider-Man saluted. "On it!" He shot a webline and swung toward the building.

Just as Natasha moved to engage, a blur of blue shot past, and suddenly, she was wired to a nearby plane.

Pietro Maximoff skidded to a stop while smirking. "Sorry, Agent Romanoff. You're grounded."

Tony's eyes widened, but before he could react, a red glow surrounded him, Rhodey, and Natasha. Suddenly, the three of them were slammed into the ground with a force that rattled the pavement.

Wanda Maximoff stepped forward with her eyes and hands glowing with chaotic energy. Clint walked beside her while smirking.

Tony grunted and is trying to push himself up. "Damn, Wanda. That's a nice trick—using illusions to make it look like you were playing along. Guess Peter's training really paid off."

Wanda tilted her head slightly and her voice is calm but cold. "I don't like being locked up. And for your info, that wasn't me."

....

Inside the abandoned airport terminal, Spider-Man flipped through the air, webbing across steel beams and structures as he dodged Sam Wilson's aerial attacks and Bucky Barnes' powerful strikes.

"You know," Peter quipped while twisting mid-air to avoid Falcon's thrusters, "I was really excited about this internship, but I gotta say—this wasn't on the brochure." He landed on the ground near Bucky.

Bucky lunged forward with his metal arm swinging toward Spider-Man's head in a devastating punch. But before the blow could land, Peter casually caught Bucky's arm mid-swing and held it in place.

Bucky's eyes widened in shock as he struggled to pull free.

Peter tilted his head. "Whoa. Dude, you got a metal arm? That's awesome!"

Bucky yanked back hard, but Peter's grip didn't budge. His fingers tightened slightly, and for the first time, Bucky felt something stronger than himself holding him in place.

Falcon took the opportunity to strike, his wings propelling him forward as he aimed a hard kick at Peter's back. But at the last second, Spider-Man shot a webline, yanking himself out of the way.

"Sorry, Mr. Birdman!" Peter called out, flipping mid-air and landing on a nearby beam. "Wait—can I call you that? Or is that offensive?"

Sam huffed, his visor locking onto Peter. "You talk too much."

Peter shrugged. "I get that a lot!"

Before Sam could respond, Peter shot out two quick weblines—one at Sam's thruster, yanking him downward, and the other at Bucky's legs, pulling them out from under him. Both men went crashing to the floor.

With expert precision, Spider-Man jumped between the two and rapidly webbed them up, pinning their arms to their sides.

"Okay, so I might have gone a little overboard," Peter admitted, taking a step back to admire his work. "I just wanted to impress Mr. Stark, you know?"

Sam, still pinned to the ground, grumbled, "Kid… I don't know if you've been in a real fight before, but usually, there's not this much talking."

Peter scratched the back of his head. "Yeah… my bad."

Suddenly, Sam's wrist flicked, and with a simple command, his drone Redwing whirred to life. The small metal bird shot forward, grabbing onto Peter's webbing and yanking him hard through the air.

"Wait—WHAT?!—" Peter yelped as he was dragged backward with his limbs flailing.

The last thing he heard was Sam chuckling. "I hate you, kid."

Bucky turned to Sam as he broke free from the webbing with a pocket knife. "That kid's annoying."

Sam smirked. "You'll get used to it."

.....

Outside, Wanda's crimson energy swirled around her fingers as she kept Iron Man and War Machine pinned to the ground, their suits struggling to move under the intense force of her telekinesis. She felt them trying to push back, their thrusters flaring against her hold, but she didn't let up.

Natasha, having managed to slip out of her restraints, darted toward Pietro with her Widow's Bite crackling with electricity. She lunged at him, but before she could make contact, Pietro moved—blurring past her in a split second before appearing behind her. He smirked.

"Really, Nat? You thought that would work?" He didn't give her time to react before driving a fist into her stomach, making her double over. "You need to be way faster than that."

Before he could revel in his victory, his instincts flared. Something was wrong.

A shadow loomed behind him, silent and precise. Pietro spun around just in time to see a figure clad in a sleek black cat-like suit. Before he could react, a powerful punch connected with his face.

The world blurred. Pietro hit the ground, out cold.

Wanda's eyes flickered toward him, and she let out an exasperated sigh. "Again? Pietro, you always let your guard down!"

Before she could react further, a searing laser cut through the air, striking dangerously close to her. She barely managed to shield herself with a force field, the impact pushing her back slightly. Slowly, she turned her gaze to the floating figure descending toward them.

Vision.

His cape billowed behind him as he hovered just above the ground, his expression calm yet firm. "Wanda," he said in that unnervingly serene tone of his, "please. Surrender. This has gone on long enough."

Wanda clenched her fists and her power crackling around her as she glared at him. "Not happening."

Above them, Iron Man and War Machine took to the air, breaking free of her hold. Tony's voice rang out through the comms. "Alright, enough talking. Let's end this."

The air was filled with the whine of repulsors as they opened fire.

The battlefield erupted into chaos.

Clint took one look at the approaching Natasha and sighed, twirling his staff. "So, uh… we're still friends, right?"

Nat smirked as she took a fighting stance. "Depends on how hard you hit me."

As Natasha and Clint clashed, Wanda turned her focus back to the most immediate threats—Vision and the Panther.

Black Panther moved with deadly grace, his claws extended as he rushed toward the location of Bucky, intent on taking him down. But before he could reach him, a wall of red energy slammed into his chest, sending him skidding across the tarmac.

Wanda tilted her head slightly, amusement flickering in her eyes. "Not so fast, kitty."

Vision made a move to help, but Wanda turned her attention to him, her eyes glowing a deep crimson. The air around her warped, reality bending under her will. "You're really going to fight me, Vision?" she asked, her voice softer now. "I thought we were past this."

Vision hesitated for the briefest moment—but it was all Wanda needed. With a flick of her fingers, she sent him crashing into a nearby cargo crate.

Soon the battlefield become a chaotic mess. The airport tarmac was littered with wreckage as both sides clashed.

On one side, Natasha and Clint were trading blows, their movements precise and calculated. Clint dodged a roundhouse kick and countered with a sweep, "Are we seriously doing this, Nat?" but Natasha flipped over his attack and landed gracefully, smirking. "You tell me. Still holding back, Barton?" she teased.

Clint huffed. "I like my ribs unbroken, thanks."

A few yards away, Wanda was having no trouble handling Vision and Black Panther. With a flick of her wrist, she threw Vision into a cargo truck, the impact leaving a dent in the metal.

Before he could recover, her red energy surrounded his body, hacking directly into the Mind Stone. His form flickered and turned intangible against his will.

"Let's see how you like being out of control," she muttered before slamming him into the ground—then deeper, burying him beneath the tarmac.

Black Panther lunged at her, his claws slashing through the air. Wanda flicked her wrist, sending him flying into a stack of cargo crates. He groaned as he struggled to rise.

Across the battlefield, Steve was locked in combat with Tony and Rhodey, his shield blocking repulsor blasts as he fought both armored men. Rhodey came in from the side, trying to flank him, but Steve rolled away and countered with a throw that sent the shield slamming into his chest.

Scott, meanwhile, had shrunk down, darting through the battlefield as he pursued Spider-Man. "Alright, web-head! Let's see what you got!"

Wanda turned, scanning the field—and her gaze landed on Peter Parker.

For the first time in the fight, she hesitated.

He reminded her too much of her Peter.

For a second, she saw her Peter—the one from the other universe—the one who trained her, who liked her. The one who made her laugh. The moment passed, but the hesitation remained.

Her grip on her powers faltered slightly.

Shaking off the thought, she turned to Pietro, who was still unconscious on the ground. With a gentle touch, she flooded his body with her energy, jolting him awake.

His eyes snapped open, and he groaned. "Ugh… did someone get the license plate of that truck or should I say suit?"

"Get up," she muttered. "And stop getting knocked out."

Tony, realizing they were losing, gritted his teeth. "Alright, anyone on our side got some big moves? I'm open to suggestions."

Before he got an answer, Wanda blasted him—his suit sparked as she hacked into his systems, causing his arc reactor to flicker on and off.

"Dammit—Wanda, stop messing with my suit!"

Meanwhile, Pietro blurred across the battlefield, sending Steve and Bucky straight into the Quinjet before turning back to mess with the rest of Iron Man's team.

But Spider-Man had been watching.

"Okay, you're fast," Peter said, eyes tracking the speedster. "But even fast guys don't see everything."

Just as Pietro made his next run, Peter webbed the exact spot he was about to step into.

Pietro hit the webbing hard, his momentum flipping him mid-air before he crashed onto the ground, stuck.

Pietro hit the webbing at full speed. Spider man began webbing him up.

"Oh, come on!" he shouted, completely tangled in the sticky mess.

"See, the trick is," Spider-Man quipped, hanging upside down, "you gotta look before you run at full speed."

Before Pietro could free himself, War Machine landed nearby and delivered a powerful punch, knocking him out again.

Wanda's eyes flared.

"Why the hell are you getting knocked out so easily?!" she yelled in frustration. "You're a fucking speedster!"

A massive red wave exploded from her, sending everyone in Tony's team flying backward. She didn't stop there. Her powers surged, lifting nearby debris and using them to trap Iron Man's team beneath broken metal and rubble.

Meanwhile, Steve, Sam, and Bucky had started the Quinjet, preparing for takeoff.

"Not happening!" Rhodey shouted. Breaking free from Wanda's hold, War Machine and Vision who just got out of the underground, took off, flying straight for the jet.

But Wanda wasn't done.

She fired a devastating blast—Vision phased just in time, letting it pass through him—but the energy slammed directly into War Machine's arc reactor.

"Rhodey!" Tony shouted as War Machine's suit short-circuited.

The power cut out, and Rhodey's suit failed mid-air.

He plummeted.

Everything stopped seeing this.

"Shit, shit, shit!" Tony rocketed after him, but he wasn't fast enough.

Panic set in as both teams abandoned their fights to chase after him, but the ground was getting closer.

Rhodey was about to hit the ground—but he stopped mid-air.

Gently, he was lowered to the ground, a soft glow surrounding his form. As his boots touched the pavement, and then the energy faded.

Silence.

Everyone got there and turned.

Peter stood there with his arms crossed and his eyes scanning the battlefield. He let out a tired sigh before glancing at Spider-Man. "Are you guys done with your kid fight?"
