Work Text:
The world was quieter now, but not peaceful.
Ash drifted through the air like gray snow as the small band of survivors—Avengers, soldiers, and one little boy—moved through the city’s bones. Buildings leaned on each other for support. Cars lay flipped and rusted, like toys dropped and forgotten by giants. The faint hum of wind through shattered windows filled the silence between them.
Peter clung to Bucky’s side, his small hand hooked in the strap of Bucky’s vest. His stuffed dinosaur, Sleepy, dirt-streaked and missing a button eye, peeked out from the backpack slung across his shoulders.
“Where are we going?” he asked softly, stepping carefully over a chunk of broken concrete.
“Home,” Tony said from ahead, voice rough but steady. “Stark Tower. If the backup generators held, there’s still power there. Food. Shelter. Maybe even some working tech.”
Peter blinked up at him. “It’s safe?”
Tony’s lips twitched, almost into a smile. “It’s safer than out here, kid.”
The ground rumbled faintly beneath them. Instinctively, every Avenger froze. Natasha lifted her rifle, eyes scanning the hazy street ahead. Sam tensed, ready to take off at the first sign of trouble.
That’s when they heard it—an echoing, wet clicking sound.
It came from somewhere to their right. Then another joined it. Then two more.
Out of the alley’s gloom crawled something that might’ve once been human, if you squinted and ignored the claws, the wrong angles of its limbs, and the way its head unfurled like a grotesque flower, layered with rows of teeth instead of petals. Its skin was slick and pale, pulsing faintly with veins that glowed icy blue beneath the surface. Blue blood dripped from its mouth, sizzling where it hit the pavement.
Peter’s breath hitched. He instinctively pressed closer to Bucky, who lowered his metal arm protectively in front of him.
“Eyes up,” Steve ordered quietly. “We’ve got movement at three o’clock—no, make that 10.”
More creatures slithered from the fog. Their clicking built into a chorus, low and awful, like a broken lullaby.
Tony raised his repulsors. “They’re hunting.”
“Then let’s make sure they don’t catch anything,” Natasha muttered.
The creatures lunged.
The air exploded into chaos—gunfire, repulsor blasts, metal clashing against bone. Sam swooped low, drawing two off the ground. Yelena was a blur of motion, flipping her knife into one’s open maw before kicking it away. Steve’s shield sang through the air, slamming into another creature’s chest with a wet crunch.
Peter was ducked behind a burnt-out car, covering his ears. He knew he wasn’t supposed to move—but when a creature broke through the line, scuttling toward him on long, jointed arms, he screamed.
Bucky was there before it could reach him. The Winter Soldier moved with brutal precision—three shots, one swing of his metal arm, and blue blood splattered across the pavement. He grabbed Peter and held him tight for just a second.
“You okay, kid?”
Peter nodded shakily, eyes wide. “You told me to stay put.”
Bucky managed a strained smile. “You did good.”
They fought until the last one fell, blue blood seeping into the cracks of the road, glowing faintly like dying embers.
Silence reclaimed the street, broken only by the ragged breaths of the living.
Tony surveyed the carnage, jaw tight. “They’re getting bolder,” he said. “Last time, we only saw 7 or 8.”
“They’re migrating,” Natasha said grimly, wiping her blade clean. “Something’s driving them north.”
Steve looked down at Peter, who was clinging to Bucky’s sleeve again. “Then we move faster. The Tower’s eight miles away—we make it by nightfall, or we don’t make it at all.”
Peter swallowed, small but determined. “We’ll make it.”
And somehow, when he said it, everyone wanted to believe him.
By mid-afternoon, the world was a furnace. The sun, filtered through the perpetual haze of smoke, glowed dull red—more like a warning light than a star.
They walked through what had once been a street and was now just a graveyard of metal and dust. Crumbled buildings leaned at impossible angles, their shadows stretching long and crooked across the road.
Peter’s small hand was swallowed in Bucky’s gloved one. His Sleepy bounced lightly against his back, and every so often he’d mumble something under his breath—counting steps, maybe, or whispering to the toy to keep it brave.
It was quiet. Too quiet. Even the wind seemed to hold its breath.
Then, from under a half-collapsed overhang, something red caught Peter’s eye.
A toy fire truck.
Its paint was chipped, one wheel missing, but when the light hit it just right, it gleamed. The kind of red that looked alive in a world gone gray.
Peter blinked and stopped walking. “Mr. Bucky?”
Bucky hummed, still scanning the horizon. “Yeah, kid?”
“There’s—” Peter slipped free of his grasp before Bucky could react. “—a truck!”
He scampered a few feet ahead, sneakers crunching on debris.
“Peter!” Sam’s voice barked out from above, his wings half-deployed even before anyone else could move.
Bucky lunged forward, but Sam got there first—swooping down in a gust of wind and scooping Peter clean off the ground just as the boy’s hand reached toward the toy.
“Hey!” Peter squeaked, kicking his legs as Sam held him tight. “I just wanted it! It’s a fire truck!”
“Yeah, well,” Sam said, voice sharp with nerves, “this one’s not for playtime, little man.”
He backed up a few feet, setting Peter down near the others, keeping a firm grip on Peter’s shoulder. Tony and Natasha both crouched next to the toy, that’s when Tony saw it. Tiny flecks—blue, almost luminescent—glowing faintly on the truck’s surface. They shimmered like dust motes, but when the wind shifted, the particles seemed to crawl.
“Blue spores,” Tony muttered grimly. “Good catch, Wilson.”
Natasha nodded, face set. “That’s what they come from. Humans touched with the spores don’t die—they change.”
Peter’s eyes went wide. “Change like… into the monsters?”
Bucky crouched beside him, meeting his gaze. “Exactly like that, buddy.”
Peter’s lower lip wobbled. “I didn’t know.”
“I know,” Bucky said softly. “That’s why you stay close, okay? You see anything glowing blue, you stay away.”
Peter nodded, but his voice was tiny when he whispered, “It was just a toy.”
Sam sighed, rubbing the back of his neck. “I know, kid. But trust me—you don’t wanna play with that one.”
Yelena stepped forward and flicked a small piece of metal toward the toy. The second it hit, the fire truck crumbled into ash, blue embers flickering before dying out.
Peter flinched. His hand crept into Bucky’s again, gripping tight.
Bucky squeezed back. “You’re okay,” he murmured. “That’s all that matters.”
They kept walking.
The wind picked up again, carrying whispers of static and the faint, wet clicks of distant creatures. Peter stayed close this time, eyes darting from shadow to shadow—but every once in a while, his gaze drifted back to where the fire truck had been.
It was gone now, just like everything else.
But the lesson stayed.
The city stretched on forever.
Even with the sun dipping low behind the broken skyline, it felt like they hadn’t made any progress at all. Every street looked the same—cracked pavement, overturned cars, windows gaping like empty eyes. The air tasted of metal and smoke, and even the wind seemed too tired to blow.
Peter’s legs hurt. His knees ached, and the strap of his backpack dug into his shoulder. He’d tried not to complain (after all he begged Bucky to let him walk)—he really had—but his feet kept dragging more and more with each step.
Bucky noticed first. “Hey, bud,” he murmured, slowing his pace, “you okay?”
Peter nodded, even though tears prickled in the corners of his eyes. “M’fine.”
“You’re limping,” Bucky said gently. “You trip?”
Peter shrugged, then stumbled over a loose chunk of asphalt as if to prove the point. He caught himself on Bucky’s arm, and his voice cracked as he whispered, “I don’t wanna walk anymore.”
The words were so small. So heartbreakingly honest.
Bucky stopped, glancing at the others. Tony and Steve exchanged a look—they were all exhausted—but before anyone could speak, Clint dropped to one knee beside Peter.
“Hey, little man,” Clint said, his tone soft and warm despite the weariness in his face. “I’ve got two shoulders and a full tank of awesome. Wanna ride?”
Peter blinked at him, surprised. “You’d carry me?”
“Sure,” Clint said, smiling faintly. “But only if you promise not to drool on me.”
A tiny, tired giggle escaped Peter before he nodded. “’Kay.”
Bucky helped lift him up, settling Peter on Clint’s back. The boy’s arms automatically looped around the archer’s neck, his head resting against Clint’s shoulder.
Rhodey stepped up then, crouching to grab Peter’s small backpack. “I’ve got this, buddy,” he said, clipping it to his own gear. “You just focus on hanging tight.”
Peter mumbled something—half thanks, half sleepy hum—and the group began to move again.
The pace slowed, but no one minded. The sound of Peter’s soft breathing against Clint’s shoulder felt like something fragile and sacred in the silence. Every so often, Clint would shift his grip or crack a quiet joke under his breath, and Peter’s drowsy laughter would float through the air like a spark of warmth in the cold.
When they reached a stretch of road lined with shattered streetlights, the group paused for water. Steve took first watch, scanning the rooftops. Bucky leaned against a car, eyes flicking between the shadows and Peter.
Tony exhaled, voice low. “He’s holding up better than most adults I’ve encountered.”
Bucky nodded, watching Peter’s small form curled sleepily against Clint’s back. “He’s stronger than he knows.”
Rhodey looked toward the horizon, where the faint outline of Stark Tower shimmered through the smoke. “Then let’s make sure he gets there to find out.”
They started walking again, slower, quieter—but together. And for the first time in a long time, it felt like maybe that was enough.
They stopped when the sun began to melt into the horizon, its dying light spilling gold over the wreckage. The street they’d found was quiet—abandoned storefronts and a collapsed overpass offering just enough cover for the night.
For the first time all day, Tony called for a rest.
Pepper immediately took charge, finding a dry patch of pavement between two walls and spreading out a tarp. Natasha helped her unpack what little food they had—mostly ration bars, a few sealed cans, and a half-crushed bag of rice that Tony had miraculously kept dry.
“This isn’t exactly five-star dining,” Pepper murmured, turning a dented can over in her hand.
Natasha smirked. “We’ll call it rustic.”
“Rustic apocalypse chic,” Tony muttered from where he was tinkering with a broken power cell.
Bucky crouched beside Peter, helping him out of Clint’s makeshift carrier. The boy wobbled a little, bleary-eyed from his nap, before blinking at the small, improvised camp forming around him.
“Are we staying here?” he asked, rubbing one eye.
“For now,” Bucky said. “Gotta rest these legs.”
Peter looked down at his sneakers, which were more gray than red now, coated in dust. “They hurt,” he admitted.
“Yeah, mine too,” Clint said as he dropped beside him with a grunt. “We’re starting a club. First rule—complaining is mandatory.”
That got a little giggle out of Peter.
When the scent of warm food finally drifted through the air, his head perked up instantly.
Pepper and Natasha had worked small miracles—somehow turning the meager supplies into a thick rice-and-vegetable stew. The smell wasn’t fancy, but to Peter it was the best thing in the world.
His stomach growled audibly, and Tony chuckled. “Someone’s ready to eat.”
“I’m really hungry,” Peter said earnestly, eyes wide as Pepper handed him a steaming bowl.
“Careful—it’s hot,” she said, smiling softly. “Blow on it first.”
Peter nodded, puffing little breaths over the bowl like he was on a mission. When he finally took a bite, his whole face lit up.
“It’s so good!”
Pepper’s heart twisted in her chest. “I’m glad, sweetheart.”
The others gathered in a loose circle around the fire—what little of one Tony dared to make. Rhodey passed out ration bars, Clint told some nonsense story about “prehistoric monster pigeons,” and for a fleeting few minutes, the world didn’t feel so broken.
Even Natasha smiled faintly when Peter offered her the last spoonful from his bowl, insisting she take it because “you cooked it, so you deserve it.”
Bucky sat back, watching the scene unfold. Peter leaned against his arm, content and sleepy, clutching Sleepy against his chest. The little boy’s lashes fluttered as he murmured, “It feels like home again.”
Bucky swallowed hard. “Yeah, kid,” he said quietly. “Kinda does.”
For the first time in days, the night didn’t seem quite so cold.
The fire had burned down to glowing coals.
Most of the group slept in shifts—Steve propped against a wall, shield resting at his side; Natasha and Yelena perched on watch, silent and still as stone. The only sounds were the faint crackle of embers and the soft rustle of breathing.
Peter had fallen asleep curled beside Bucky, his head tucked against the soldier’s shoulder. His stuffed Dino was caught between them, one paw resting over Peter’s small hand like it was standing guard too.
But sometime past midnight, the quiet changed.
A low clicking sound echoed from somewhere beyond the street—faint at first, like dripping water. Then another. Then a third.
Peter stirred. His eyes blinked open to the dark, and for a moment, he forgot where he was. The shadows loomed too big. The silence felt too heavy. He sat up quickly, heart hammering.
“Bucky?” he whispered.
The man didn’t stir. His breathing was steady—finally deep, finally resting after days without it.
Peter bit his lip. The noises outside grew louder. Wet clicks, followed by a soft scraping sound. Like claws on pavement.
He clutched Sleepy tighter and looked toward the firelight. Across the camp, Tony was awake, tinkering quietly with a repulsor gauntlet—his only working one. The faint blue glow illuminated his face.
Peter shuffled closer, trying not to make a sound. When he reached Tony’s side, he tugged lightly on the man’s sleeve.
Tony glanced down instantly. “Hey, kiddo. Shouldn’t you be in dreamland?”
Peter’s voice shook. “Something’s out there.”
Tony’s expression softened, the exhaustion fading from his eyes. He set the gauntlet down carefully and crouched to meet Peter’s gaze. “Where?”
Peter pointed toward the edge of the street, where the dark swallowed everything, worry in his eyes. “It’s clicking.”
Tony didn’t dismiss him. He turned his head, listening—and sure enough, the sound came again. Low, distant, but real.
He stood quietly, moving to grab his repulsor. “Okay,” he whispered. “Back to your spot, champ. I’ll check it out.”
Was it stupid to go out alone at night? Yes, yes it was. But this is Tony we’re talking about.
Peter hesitated, fingers twisting in the hem of Tony’s jacket. “Don’t go far.”
Tony knelt again, gently tapping Peter’s nose. “Hey—look at me. You see that light?” He pointed toward the faint, steady glow of the fire. “If anything happens, you go right there, got it? That’s our safe zone.”
Peter nodded, swallowing hard. “Promise you’ll come back?”
Tony gave him a faint smile that didn’t quite hide the fear behind it. “I’ve got a pretty good track record with that, kid.”
He moved toward the edge of the street, repulsor primed. The clicking stopped—then, after a beat, there was silence again. Too much silence.
When Tony returned, Natasha was awake, rifle slung and eyes scanning the rooftops. “They’re moving again,” she said quietly. “Not close, but close enough.”
Tony sighed. “We’ll keep the fire low. Rotate watch. If we’re lucky, they’ll pass.”
Bucky stirred at that, blinking awake just as Peter crawled back into his side. He wrapped an arm around the boy automatically.
“Couldn’t sleep,” Peter whispered.
“I know,” Bucky murmured, voice rough with fatigue. “You’re safe, kid. I got you.”
Peter rested his head against Bucky’s chest, listening to the slow thump of his heartbeat until the sounds outside faded to nothing.
The monsters moved on. The night stayed whole.
And when dawn finally bled across the sky—soft and gray and trembling—Peter was still curled up safe in Bucky’s arms.
