Omnitrix in Marvel

Adam was just an ordinary guy with a love for movies, web novels, and anything that could make life feel less boring. Then, without warning, he is ripped out of his room and dropped into New York City at the worst possible moment, right before the Battle of New York begins. Armed with a limited Omnitrix that can unlock only ten aliens, Adam is forced to survive inside the Marvel Cinematic Universe. Unlike the real Ben Tennyson, Adam does not fully transform. Instead, the Omnitrix keeps his human appearance and pushes alien powers into his body. With Chitauri descending from the sky, heroes fighting across Manhattan, and canon events unfolding around him, Adam has only one advantage: he knows what is coming. But in a world like Marvel, knowledge alone is not enough. To stay alive, protect himself, and maybe even change the future. This is the story of a sarcastic outsider thrown into the MCU, where every fight can rewrite destiny and every unlocked alien can change the balance of the world. — Description from novelcodex.org
