Synopsis
In a world where superheroes clash and cosmic threats loom, an ordinary Marvel fan from Earth dies and awakens as Alex Kane—a newborn in the MCU, armed with the ultimate cheat: the power to analyze any DNA and selectively replicate the abilities, talents, and traits of heroes, villains, and anyone he encounters. No overpowered system handouts. No instant godhood. Just smart, calculated collection—starting small with empathy from his struggling single mother, subtle intellect boosts from teachers, and fractional super-soldier enhancements stolen in secret. He grinds like the web novel protagonists he once read about: investing in future tech trends he remembers, building a shadowy tech empire from humble game prototypes, and forging an advanced AI that evolves into something rivaling JARVIS. Alex isn't a reckless savior. He's a good man who puts family and true friends first—extending his mother's life with copied resilience, shielding his childhood crew from danger, and quietly reducing civilian deaths in every major battle he influences. He helps the Avengers carry their burdens: easing Tony's guilt, supporting Wanda through her grief, grounding Peter in friendship, and offering Black Widow a rare space of genuine trust. As powers stack—Stark's genius sharpening his mind, Cap's durability hardening his body, Asgardian longevity promising centuries, glimpses of chaos magic and speed—he navigates the timeline with meta-knowledge and ruthless pragmatism. He builds Kane Tech, a company that delivers real-world innovations to help Earth while quietly amassing wealth during Stark's dips and Ultron's chaos. Romances bloom slowly and authentically: deep emotional bonds with Wanda Maximoff (shared understanding of loss and power), Gwen Stacy (intellectual equals navigating hero life), and Natasha Romanoff (mutual respect forged in shadows and missions). No conquests for power—just real connections that grow amid the chaos. Even Nick Fury hesitates to approach him. Alex reads people like open books, exposes Hydra spies worldwide through his AI, and offers advice that cuts too close—making him an invaluable, yet unnerving, ally in the shadows. In a universe racing toward Thanos and beyond, Alex doesn't seek the spotlight. He seeks control, longevity for those he loves, and a world where fewer innocents pay the price for heroes' wars. But as he collects the DNA of gods, monsters, and multiversal threats, one question lingers: How long before the power changes the man who once just wanted to survive—and protect his own? DNA Replication — Smart progression. Genuine bonds. A shadow guardian rewriting the MCU, one copied trait at a time. (Perfect for fans of progression fantasy, careful power scaling, emotional depth, light harem elements, and MCU canon with smart twists!) Written using AI

Chapter 1 - Chapter 1: Baby Steps and DNA Discoveries

*(Approximately 1000 words)*

The first thing Alex Kane truly remembered—beyond the instinctive blur of warmth, milk, and muffled voices—was the sensation of *knowing* something was different.

He was six months old, cradled in his mother's arms after a twelve-hour shift at Queens General Hospital. Elena Kane smelled of antiseptic soap and faint lavender from the cheap body wash she used to feel human again. Her heartbeat was steady but tired, a rhythm Alex could almost map in his mind like lines on a screen. When his tiny fingers wrapped around her index finger, something flickered inside his consciousness.

A translucent panel appeared in his vision, floating like an augmented reality overlay only he could see:

*[DNA Sample Acquired: Elena Kane (Maternal Human Baseline)]* 

*[Analysis: 99.7% standard Homo sapiens genome. Detected traits – Enhanced Empathy (occupational adaptation from nursing), Moderate Physical Resilience (survivor of early hardship), Minor Metabolic Efficiency.]* 

*[Selective Replication Available. Copy? Y/N]*

Alex's baby brain processed it with startling clarity. He didn't have words yet, but he had intent. *Yes. Empathy. Just a little.* He focused, and a gentle warmth spread through his chest like sinking into a warm bath. The exhaustion radiating from his mother sharpened into something he could name: bone-deep fatigue mixed with quiet pride, worry about bills, fierce love for the squirming infant in her arms.

He stopped fussing so much after that. When Elena came home shattered, he would reach up, pat her cheek with surprising gentleness for a baby, and stare into her eyes until she smiled despite herself. "You're such a good boy, Alex," she'd whisper, kissing his forehead. "Mommy's little helper."

He wasn't trying to be a saint. He simply understood, earlier than any child should, that keeping her happy and healthy meant keeping his only anchor in this dangerous new world stable. Family first. Always.

By age two, the interface had become second nature. He tested it obsessively in secret.

At the playground near their cramped one-bedroom apartment, another toddler shoved him off the slide. Alex hit the mulch, scraped his knee, and—while the other boy's mother rushed over—managed to snag a single blond hair from the kid's sweater.

*[DNA Sample: Michael Torres, age 3. Analysis: Standard human. No notable enhancements. Minor traits – Early coordination development. Copy?]*

Useless. He discarded it mentally. But the next week, when Michael fell and started wailing, Alex toddled over, patted his back, and said his first full sentence: "It okay. Mommy come."

The other boy stopped crying almost instantly. Alex felt the shift in emotion like turning a dial. Empathy wasn't just copied; it was refined.

Elena noticed. "You're so sweet with the other kids, mijo. Where'd you learn that?"

Alex just smiled his gap-toothed smile and hugged her leg. He couldn't say, *From you. And from every person I touch.*

Age four brought kindergarten. Public school in Queens was loud, chaotic, full of opportunity.

His teacher, Mrs. Ramirez, had beautiful cursive handwriting and endless patience. One day Alex "accidentally" tugged a long black hair from her cardigan when she bent to tie his shoe.

*[DNA Sample: Maria Ramirez, age 34. Analysis: Above-average verbal intelligence, strong emotional regulation, pedagogical aptitude. Minor linguistic talent (bilingual fluency).]* 

*[Selective Copy Options: Emotional Regulation +0.4σ, Verbal Reasoning +0.7σ. Copy?]*

He took both, selectively. His sentences grew more complex overnight. Teachers started calling him "gifted." Classmates gravitated toward him because fights seemed to dissolve when he was around—he could sense rising anger and defuse it with a well-timed question or joke.

He wasn't a peacemaker for the greater good. He did it because bullies disrupted his focus, and he liked the calm circle of friends that formed around him. Tommy Chen, fat and bespectacled; Sofia Alvarez, fast-talking and fearless; little Jamal who drew superheroes on every scrap of paper. They were his people now. Protecting them meant protecting his slice of normalcy.

Money came next.

By age five (2000), Alex remembered the dot-com bubble, 9/11 (still three years away), the iPod launch, Google going public. Small things, but compoundable.

He started "playing investor" with Elena. She thought it was adorable when he pointed at the newspaper and said, "Mommy, buy that one. Apple make music player soon."

She laughed, but she listened—just a little. Twenty dollars here, fifty there, funneled into index funds and a few individual stocks he insisted on. When the 2000 crash hit, he told her calmly, "Don't sell. It come back. Wait."

Elena stared at her eerily prescient five-year-old. "How do you know these things, baby?"

"TV," he lied, hugging her. Inside: *Because I watched eleven movies about the future.*

The account grew slowly—nothing dramatic yet. Enough for new shoes, a better TV, an extra twenty in the emergency jar each month. He wasn't building an empire at five. He was planting seeds.

Longevity was the real obsession.

He read every children's science book the library had, then begged Elena to borrow adult ones on genetics and aging. Telomeres. Oxidative stress. Caloric restriction. He copied minor resilience traits from anyone who looked unusually healthy—an old man at the park who still jogged, a nurse coworker of Elena's who never got sick.

Each copy was tiny, fractional. But stacked over time? He felt his own small body recovering from colds faster, scrapes healing cleaner. He shared the subtle resilience with Elena too—slipping traits during hugs, during story time. She started looking less haggard, laughing more easily.

One night, age six, Elena tucked him in and whispered, "I don't know what I did to deserve such a special boy."

Alex reached up, touched her cheek, and copied one more sliver of her stubborn strength.

"You deserve everything, Mom," he said seriously. "I'm gonna make sure you live a long, long time."

She kissed his forehead, thinking it was childish sweetness.

Alex stared at the ceiling after she left, interface glowing faintly in his mind.

*[Current Status: Cumulative enhancements – IQ +1.1σ, EQ +1.4σ, Physical Resilience +0.8σ, Projected Lifespan Extension: +4–7 years (baseline human).]*

*Not enough,* he thought. *Not nearly enough.*

Outside, Queens hummed with distant sirens and late-night arguments. Somewhere in the city—maybe the world—people with real power were living their lives. Tony Stark was probably building his next weapon in a cave somewhere (no, wait—timeline check: still weapons phase). Mutants were hiding. Gods walked among men, unaware or uncaring.

Alex closed his eyes.

*One step at a time. Collect. Grow. Protect what's mine.*

He drifted to sleep dreaming of glowing interfaces, blood samples, and a future where no one he loved ever had to die too soon.
