Fighting against me || Peter Parker
summary: Peter is on iron man’s side, your on captain americas side, yet you both don’t know this. You both don’t know each other identities until your phone falls out and slides towards peter….
The airport had already turned into chaos.
Cracked concrete. Smoke drifting through the air. The sharp clang of metal against metal echoed as teams clashed—Iron Man firing repulsors while Captain America blocked with his shield, the tension between them heavier than the fight itself.
And swinging in—late, slightly breathless, and trying very hard to look like he knew what he was doing—was Spider-Man.
“Okay, wow—this is… this is a lot bigger than YouTube clips,” Peter muttered under his mask, landing awkwardly before immediately trying to play it cool. “I mean—hi everyone! Big fan of—well, not this, but—”
A blast shot past his head.
“Right. Focus.”
Across the battlefield, another figure moved with precision and force—fast, sharp, relentless.
Y/N.
Masked. Anonymous. Just another fighter in the chaos.
Peter didn’t recognize her.
She didn’t recognize him.
They collided without warning.
A sudden impact—THWACK—
Her strike caught him clean across the jaw, snapping his head to the side.
“Woah—okay!” Peter stumbled back, hands up. “You hit hard! Like—really hard. Is that, like, a gym thing or—”
She didn’t answer. She came at him again.
Fast.
A kick aimed at his ribs—he flipped backward just in time, barely avoiding it.
“Alright, alright, I get it,” he said, webbing the ground and yanking himself sideways. “We’re doing the whole ‘no talking, just punching’ thing. That’s cool. Not my favorite, but cool.”
Y/N lunged again, this time catching his shoulder. He winced.
“Okay—ow—that one counted.”
He shot a web toward her wrist—she twisted, dodging, grabbing it mid-air and using it to yank him forward.
Their bodies collided again, both hitting the ground hard.
For a moment, they froze—faces inches apart behind their masks.
Neither spoke.
Then—
She headbutted him.
“OW—okay, wow! Definitely not pulling punches!”
He rolled away, flipping back onto his feet. She followed instantly.
Their fight turned sharper—faster. More personal, somehow, even without knowing why.
He landed a light hit to her side.
She retaliated with a brutal sweep, knocking his legs out from under him.
“Alright—rude,” he groaned, flipping back up. “You’re really committed to this.”
“I don’t go easy,” she snapped, voice strained but fierce.
Something about her voice made him hesitate—just for a fraction of a second.
But before he could think—
A blast from behind—one of Tony’s allies—hit near y/n.
The explosion sent her flying.
She hit the ground hard, skidding across broken concrete.
Peter froze.
“Hey—!”
He rushed toward her immediately, landing beside her.
“Hey, hey—are you okay?” he said quickly, kneeling. “That looked bad. I mean—really bad. I’ve seen bad, that was—like, top ten bad—”
She groaned, trying to push herself up.
“Don’t touch me—”
“Whoa, okay, sorry—just—” he held his hands up, panicked. “Look, I know we’re fighting, but you’re hurt, and—and my girlfriend—she always says, you know, ‘help people who need it,’ so—”
That was a mistake.
Y/N’s fist drove straight into his face.
He reeled back.
“OW—! Okay—message received!”
She forced herself up despite the pain—but her leg buckled.
Peter noticed immediately.
“Hey—no, seriously, you shouldn’t—”
She swung again.
This time, instinct took over.
He blocked it. Twisted. Knocked her back down.
“Stop—just—stop moving!” he snapped, more forcefully than before. “You’re going to make it worse!”
“I don’t need your help!” she shot back, breath shaky.
He moved in again, trying to restrain her—pinning her arms.
“Yeah, well, I’m helping anyway! That’s kind of my whole thing!”
She struggled—harder than before.
And then—
He saw it.
Blood.
Dark, spreading from her leg.
His grip loosened slightly.
“Wait… you’re bleeding.”
For a split second, everything slowed.
Then—
A blur of black.
Black Panther struck, slamming into Y/N and sending her flying again.
“HEY—!” Peter shouted, spinning toward him.
Y/n hit the ground, unmoving for a moment.
Something small skidded across the concrete near Peter’s feet.
A phone.
Peter hesitated.
Then picked it up.
The screen lit up.
And everything inside him dropped.
The lock screen photo—
Her.
And him.
Smiling.
Close.
Happy.
“...y/n…?” his voice cracked under the mask.
His head snapped up.
“STOP!”
Black Panther paused mid-step, turning slightly.
“Don’t touch her!” Peter shouted, voice breaking. “Please—just—don’t—!”
He ran to her side again, dropping to his knees.
“Baby—hey—hey, can you hear me?” His hands hovered, afraid to touch her now. “It’s—it’s me—well, you don’t—just—please wake up.”
She stirred faintly, breathing uneven.
Peter looked back at Black Panther, desperation bleeding through every word.
“She’s not—she’s not part of this, okay? She—she’s just—”
He stopped.
Because that wasn’t true.
She was part of this.
Just like him.
And neither of them knew.
He looked back down at her, voice softer now.
“We… we had a fight,” he whispered. “Last time I saw you… I didn’t even fix it.”
His hands trembled.
“I didn’t even say sorry.”
Around them, the battle still raged—but for Peter, everything had narrowed to this one moment.
“Please wake up,” he said quietly. “Please… I can’t—”
Her hand twitched.
Just slightly.
Enough to make him freeze.
“y/n/n…?”
The fight wasn’t over.
But something had changed.
Peter barely registered the noise of the battle anymore.
Explosions, shouting, metal clashing—it all faded into the background as he knelt beside her, heart pounding so hard it hurt.
“Y/n… hey… hey, come on,” he said, voice unsteady, both hands gently cupping her face through the mask. “Please wake up. Please.”
She groaned.
Her head shifted slightly in his hands.
Relief hit him all at once. “Yeah—yeah, that’s it, you’re okay, just—just stay with me—”
Her eyes snapped open behind the mask.
For a split second, confusion.
Then instinct.
Her hands shot up, shoving against his chest.
“Get the fuck off me!” she snapped, trying to push him away despite the pain. “I have a boyfriend—what is wrong with you?!”
The words hit harder than any punch she’d thrown.
Peter froze.
His grip loosened immediately, hands lifting like he’d been burned. “I—no, I wasn’t—I mean—I wasn’t trying to—”
“Back off!” she snapped again, trying to sit up, wincing sharply as her injured leg protested.
“I’m not—look, you’re hurt, okay? I was just trying to help—”
A metallic thud landed behind them.
“Kid, what are you doing?”
Tony stepped forward, armor gleaming even through the dust, his gaze flicking between Peter and the girl on the ground.
“This isn’t a charity event.”
Peter turned quickly. “Mr. Stark, wait—she’s—”
Tony didn’t hesitate. A gauntleted hand reached down, grabbing y/n by the arm and pulling her up roughly.
She gasped in pain.
“Hey!” Peter lunged forward instantly, grabbing Tony’s arm. “Stop—stop, you’re hurting her!”
Tony tilted his helmet slightly. “She’s on the other side, kid.”
“I don’t care!” Peter shot back, voice rising. “She’s injured—can’t you see that?!”
y/n struggled weakly in Tony’s grip, trying to pull away.
“Let go of me—!”
“Not happening,” Tony replied flatly, tightening his hold. “You don’t get to tap out when things go sideways.”
“Mr. Stark, seriously—just let her go!” Peter insisted, stepping closer, more desperate now. “She’s not—she’s not a threat right now!”
Tony’s attention shifted back to Peter, something sharper in his tone. “You’re getting distracted.”
Peter shook his head immediately, stepping forward again. “No—I’m not—”
“She’s on the other side,” Tony added, firmer now. “You don’t stop in the middle of a fight to play medic.”
Peter’s chest rose and fell quickly under the suit.
Then, before he could stop himself—
“She’s my girlfriend!”
The words came out louder than he meant. Raw. Unfiltered.
Everything froze.
Even through the mask, y/n went completely still.
Her breathing hitched.
“…what?”
Her voice was quieter now. Shaken.
Peter didn’t move. Didn’t breathe.
“y/n , I—”
Her head snapped up toward him, eyes wide behind the mask.
That voice.
She knew that voice.
“…Peter?”
It came out almost like a whisper.
A disbelieving one.
Peter’s stomach dropped.
Slowly, hesitantly, he reached up—just enough to peel his mask back halfway.
“Yeah…”
For a moment, the battlefield disappeared for both of them.
There was no Captain America, no explosions, no divided sides—
Just them.
Her expression shifted—shock, confusion, something deeper, something hurt.
“You—?” she shook her head slightly, trying to process it. “You’re… Spider-Man?”
“And you’re—” his voice cracked as he gestured weakly toward her suit. “You’re here. Fighting. Against me.”
A bitter, breathless laugh escaped her.
“Wow… so this is what you’ve been doing?” she said, pain threading through her words. “Disappearing. Ignoring me. Lying.”
“I wasn’t lying—I just—couldn’t tell you—”
“So you just pick fights instead?” she shot back, anger flaring despite the situation. “You don’t call, you don’t text, and then the next time I see you—you’re attacking me?”
“I didn’t know it was you!” he said quickly. “I swear, if I had known—”
“Well, you didn’t,” she cut in.
Silence fell between them again, heavier this time.
Behind them, Tony shifted slightly.
“…Okay,” he muttered, more to himself than anything. “That’s new.”
Peter didn’t even look back.
His attention stayed on her—on the way she was trying to stay strong despite the pain, despite everything.
“I was trying to protect you,” he said more quietly now. “Even before I knew it was you.”
She let out a shaky breath.
“You don’t get to say that,” she replied. “Not after everything.”
Another explosion echoed somewhere in the distance, snapping reality back into place.
This wasn’t over.
Not the fight.
Not them.
Peter hesitated, torn apart by it.
“…Your leg’s still bleeding,” he said softly, like that was the only thing he could hold onto right now. “You need to—”
“I’ll handle it,” she said, though her voice wasn’t as steady as before.
A pause.
Then, quieter—
“…You really meant that?”
He blinked. “What?”
“What you said,” she replied, not quite meeting his eyes. “Before. That I’m your girlfriend.”
Peter didn’t hesitate this time.
“Yeah,” he said simply. “I did.”
Something in her expression shifted again—still hurt, still conflicted… but softer, just barely.
Before either of them could say anything else—
“Kid,” Tony called out again, more urgent now. “We’re not done here.”
Peter clenched his jaw.
Then looked back at her one last time.
“Stay down. Please.”
She didn’t argue this time.
And as he pulled his mask back down and turned toward the fight again, one thing was painfully clear—
Nothing between them would ever be the same.
Guys I need some request ideas!!!
