Reborn in Marvel: DNA Replicator

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 mostly by AI, mostly did it for fun, anyone can use it if you like the story and write better, cause i suck at it!
