Gotham has always been Y/N Wayne's world - a city of shadows where he is known as Dark Avian, protector and predator. But when a villain from another universe invades, Gotham's streets are no longer safe. Cornered and outmatched, Y/N makes the ultimate choice: to sacrifice himself to save his city.
He expects death. What he gets instead is something far stranger. Pulled from his home universe, Y/N awakens in the Marvel Universe, a world of chaos, power, and danger unlike anything he's known. Alone, armed only with his skills and wits, he must survive, adapt, and confront the question that now haunts him: is a hero still a hero when he has no home?
