Bruce Wayne x Selina Kyle (Male!Teenage!Reader is Selina’s kid).
Rain fell softly on Gotham’s rooftops the night Selina Kyle found him. The kind of rain that didn’t cleanse the city, just made it shine a little while it bled. She’d been halfway through a job — diamond necklace, old museum, easy marks — when she heard it. A sharp cough, a groan, then silence.
She turned the corner and saw him — a boy, no older than twelve, bleeding out in an alley. The colors hit her first. The red, green, and black of a torn uniform she thought she vaguely recognized.
“Oh, sweetheart…” she whispered, crouching beside him. His mask was half gone, one eye swollen shut, skin ghostly pale beneath the grime.
“Where’s…” he croaked weakly, “...where’s my parents?”
She looked around — no adults in sight. Just a broken boy left behind by the shadows.
“Don’t worry about them, kid,” she murmured, sliding her coat over his trembling shoulders. “You’ve got someone now.”
He passed out before he could argue.
Sixteen-year-old Y/N Kyle stood at the window of their Gotham penthouse, headphones in, sketching rooftops across the skyline. His hair had grown longer, wilder. He wore black like a comfort blanket, but his smirk — that belonged to Selina.
“Y/N!” Selina called from the kitchen. “If you’re planning to brood, at least brood with breakfast.”
He turned, grinning. “I’m not brooding, I’m observing. Artists don’t brood.”
Selina arched an eyebrow. “You’re my son. You definitely brood.”
He rolled his eyes but padded over, accepting the plate of toast and eggs. “Thanks, Mom.”
That still made her heart flutter. “Any plans today?”
He shrugged. “Maybe patrol later. You know, keep the alley cats safe.”
She smirked. “That’s my boy.”
The grand hall was lit with golden chandeliers. Bruce Wayne stood with his usual composure, though Alfred caught the rare softness in his eyes as Selina entered.
“Selina,” Bruce said, voice warm. “You look radiant.”
She smirked. “Careful, Bruce. You’ll make me think you mean it.”
He smiled — the real kind. They’d been meeting often lately, patching the years with quiet conversation.
“I heard you’ve... settled down a bit,” Bruce teased lightly, pouring her tea. “Word is, you’ve got someone living with you?”
Selina’s expression softened. “Yeah. My son. Y/N. He’s sixteen now. Found him years ago. He’s... everything, Bruce.”
Bruce nodded approvingly. “You’re a mother, huh? I’m happy for you. What’s he like?”
Selina’s lips curved into a proud grin. “Smart. Quick. Bit of a rule-bender — wonder where he got that from.”
Bruce chuckled. “Sounds like someone I’d like to meet.”
“Maybe one day,” she said.
A Week Later — Wedding Planning
Selina sat on the couch beside Bruce, their wedding just months away. Alfred brought tea while they sorted through name lists, decorations, guest invites.
Bruce smiled faintly. “You know, I should probably prepare to be a stepfather. What’s your boy’s name again?”
Selina’s smile widened. “Y/N. Y/N Kyle.”
Bruce froze. The teacup nearly slipped from his hand.
“Y/N Kyle,” she repeated, puzzled. “Why?”
Bruce’s eyes went distant — haunted. “I... I had a son once. My second Robin. His name was Y/N. He... he died years ago.” His voice cracked slightly at the word died.
Selina blinked. “Oh, Bruce… I’m so sorry.”
He reached into his wallet, pulling out a worn photograph — a boy with a bright grin, mask tilted slightly askew, standing beside Batman.
“Bruce,” she whispered, voice trembling. “That’s— that’s my kid.”
“That’s him. That’s Y/N. That’s the boy I found in the alley four years ago.”
They both stared at each other, realization dawning like a sunrise after years of darkness.
The Batmobile rolled to a silent stop outside the penthouse that night. Y/N was sprawled on the couch, watching a crime documentary, when the door opened.
“Mom?” he called. “You’re home early—”
Bruce Wayne.
No — Batman.
His breath caught in his throat.
Selina stood between them, her hand on his shoulder. “Y/N, sweetheart… there’s someone you need to talk to.”
Bruce took a hesitant step forward. His voice was barely above a whisper. “Y/N…?”
(Y/N)’s eyes widened, flickering between shock and disbelief. “No. No, you— you left me.”
Bruce’s jaw clenched, emotion breaking through the stoic mask. “I thought you were gone. We searched for weeks. There was blood, the wreckage— I thought I’d failed you.”
Tears burned behind Y/N’s eyes. “You did.”
Selina squeezed his hand gently. “He didn’t know, baby.”
Silence stretched, then Bruce said quietly, “You’re alive. That’s all that matters.”
Y/N hesitated — then, slowly, stepped forward. His voice cracked. “You really thought I died?”
Bruce’s lip trembled. “Every day since that night.”
And that was enough. Y/N threw his arms around him, burying his face into the Kevlar chest. Bruce held him like he might vanish again if he let go.
Selina stood a few feet away, arms crossed, trying to hide the tears forming in her eyes. “My boys,” she whispered.
Weeks Later — The Wedding
The manor gardens glowed under fairy lights. Gotham’s most elusive pair — Bruce Wayne and Selina Kyle — finally stood hand in hand before their friends and family.
Y/N stood proudly between them, his tux crisp, his smile shy but genuine.
When the vows ended, Bruce looked at him and said, “We’ve both lost enough time. From now on, you’ll never question where you belong.”
Y/N nodded. “I know. I’m a Kyle... and a Wayne.”
Selina chuckled softly. “Perfect mix of trouble and heart.”
As they turned toward the crowd, the new family hand in hand, Gotham’s skyline shimmered behind them — dark, dangerous, and finally, just a little bit brighter.
Later that night, Y/N perched on the balcony, staring out at the city. Bruce approached, resting a hand on his shoulder.
“Thinking about patrolling?” Bruce asked.
Y/N smirked. “You know me too well.”
Selina’s voice called from inside, teasing, “If either of you ruin my wedding night with heroics, I swear—”
Bruce and Y/N exchanged identical grins.
“Like father,” Selina muttered from the doorway, “like son.”
And for the first time in years, Gotham’s dark knight and its cleverest cat finally had a family.
The manor was quieter than usual that morning. Alfred had taken Selina to the city for errands, leaving you and Bruce with a breakfast table far too large for two people who preferred rooftops.
You were halfway through a plate of waffles when Bruce set down his coffee and said, “There’s something I’ve been meaning to do.”
You glanced up, wary. “That sounds like something that’s gonna make me sweat or cry.”
He smirked faintly. “Maybe both.”
You tilted your head. “You’re terrifying when you’re vague.”
He didn’t answer, only stood and motioned for you to follow.
The Training Wing — Wayne Manor
The door opened to the training room — but it wasn’t empty.
A man in a blue suit leaned casually against the wall, twirling his escrima sticks with a grin you didn’t expect to recognize until your heart stopped.
“Hey, kid,” he said softly.
His grin faltered, replaced with something softer — like relief. “It’s really you.”
You froze in place, years of pain and memories colliding at once.
“B...Bruce didn’t tell me you—”
“He didn’t tell anyone,” Dick interrupted gently, setting the sticks down and taking a hesitant step forward. “We thought you were gone. We buried you.”
You swallowed hard, throat tight. “Guess I didn’t stay buried.”
Dick laughed weakly through tears. “No, you never did like following orders.”
That broke the tension. You laughed, and before you knew it, you were hugging — arms tight, tears spilling freely, the kind of reunion that made the years between you dissolve.
“You got taller,” Dick murmured.
“You got old,” you shot back with a grin.
He barked a laugh. “Okay, yeah, fair.”
The door opened again, and a familiar younger voice spoke from behind.
“Wait—what’s going on here? Bruce, why’s Nightwing crying?”
You turned to see Tim Drake — dressed in casual clothes, coffee in hand, confusion written all over his face.
Bruce crossed his arms. “Tim, this is—”
“Y/N,” you interrupted, smiling softly. “Guess that makes me your older brother.”
Tim blinked, eyes darting between you and Bruce. “Wait. What?”
Dick chuckled, wiping his eyes. “Yeah, surprise sibling reveal. Classic Wayne family move.”
Tim’s brain visibly short-circuited. “But—how—where have you been—”
You shrugged. “Long story. Selina found me years ago. Raised me.”
Tim’s eyes widened. “Selina Kyle? As in—Catwoman?!”
You smirked. “The one and only.”
Dick clapped Tim on the shoulder. “Welcome to the family chaos, little brother. We’re gonna need a bigger group chat.”
You were suiting up again for the first time in years. Not as Robin — that costume was gone — but something new. A blend of both worlds: black and deep red, lined with subtle silver stitching that Selina had sewn herself.
You were tightening your gloves when a sharp voice echoed behind you.
“So you’re the miracle child Father can’t stop talking about.”
You turned to see a small boy with piercing green eyes, scowling like he’d been born angry.
“Let me guess,” you said. “Damian.”
He crossed his arms. “You’re my older brother.”
You raised an eyebrow. “You don’t sound thrilled about it.”
“I simply question the necessity of another Wayne in the field,” he said stiffly. “Father already has me.”
You grinned. “Oh, trust me, I’m not trying to steal your spotlight. You seem to have plenty of ego to share.”
His glare sharpened — but then, to your surprise, the faintest smirk crept across his face. “At least you’re not boring.”
He stepped closer, eyes narrowing. “If we spar, I’ll win.”
You shrugged. “Maybe. But you’d have to catch me first.”
Dick’s laughter rang from the balcony above. “Don’t challenge him, Dami — he’s got Selina’s footwork. You’ll be swinging at air.”
Damian groaned. “You’re all insufferable.”
Bruce smiled faintly from the Batcomputer, looking at the four of you — the family he’d once thought broken beyond repair — now together, laughing, alive.
That Night — Rooftop of Wayne Tower
You stood beside Dick, the city lights reflecting off your visor.
“Feels weird being back up here,” you said quietly. “Used to think the rooftops were home.”
Dick nodded. “They still are. But now, you’ve got a few people waiting at the bottom, too.”
You smirked. “Yeah. Mom’s probably tracking me right now.”
He chuckled. “Selina Kyle tracking you? Never thought I’d see the day.”
You grinned. “Guess we both got lucky. You with Bruce. Me with her.”
“Family’s weird like that,” Dick said softly.
You looked out over Gotham — your city, your family’s city — and felt, for the first time in years, whole.
The next morning, Alfred found a note on the kitchen counter, written in your quick handwriting:
“Out with the boys. Don’t worry, Mom — I’ll bring them home in one piece.
-Love,
Y/N Kyle-Wayne.”
Selina smirked as she read it, sipping her coffee.
Bruce glanced over her shoulder, his faint smile betraying pride.
And somewhere in the skyline, four shadows leapt across the rooftops — one blue, one red, one green, one black — Gotham’s brothers in the night.
