For years, I was the silent architect behind the hero, the strategist who guided the power of the watch, only to have victory snatched away by a blinding flash of white light that tore me from my world. Now, I am an anomaly stranded in a realm of stagnant, structured magic... AND NOW... I'm CURRENTLY forced to navigate this medieval realm alongside a legendary, airheaded elf, a goofball warrior, and a human mage who communicates mostly through pouting... what can go wrong?

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.

So I lied about my Ultimate Spider-Man x Randy Cunningham 9th Grade Ninja story being my last story. It's just that I was looking through Wattpad and all I saw was one thing... Ben. FUCKING. 10!!! Keep in mind I damn well loved the show since I was a kid to now. Even the reboot and hopefully the next one is better. So I saw all these Ben 10 fics and thought why not. Anyway, on with the description. 12 year old Y/N L/N has been friends with 10 year old Ben Tennyson for forever and so was their parents. And they had the idea to send them along with Ben's know it all cousin Gwen on a trip in their Grandpa Max's RV. On their trip the boys stumbled upon two powerful watches one flashing green and the other pink. Read my version of how it started with two alien devices did what they did.
