Behind the mask of Central City's feline vigilante, Chat Noir, lies Alina Agreste—a reserved and calculating teenager, bound by the expectations of her father, billionaire fashion designer, Alexander Agreste. While Chat Noir is bold, charming, and effortlessly carefree, Alina's real life is anything but that. Raised in a world where love felt conditional and her worth was measured by perfection, she learned to downplay her emotions, suppress her desires, and accept the disappointment in her father's eyes as inevitable.

But beneath the charm and sharp wit, Alina longed for something real untainted by wealth or reputation. She never truly found that until she met Barry Allen and Kara Danvers, two heroes who not only saw her for who she was but embraced her like family. And if anyone saw the three of them together, they might mistake them for an actual family—an assumption none of them ever denied. Barry and Kara became the guiding forces in her life, protective and unwavering, filling the void her father never could.

One day, in the middle of a mission gone wrong, everything changes. A rift in space-time hurls them into another universe-a world where the Avengers reign as Earth's mightiest heroes. With no way home and no hope of ever returning, Alina, Barry, and Kara are forced to adjust to this new reality, learning to navigate a world that isn't theirs while grappling with the lives they left behind.

And if there was one thing the three were obliviously unaware of throughout the years, it was that wherever they went, trouble was always bound to follow.

★彡[ important author's note ]彡★

hello, everyone! what a surprise, i know. me reviving after two years, and actually writing this fic again. i hope this app isn't as dead anymore. but anyway, welcome to this crossover fic or welcome back for fellow returning readers.

this crossover fic will be a mix of an au and will kind of loosely follow through the mcu timeline. alina is inspired by chat noir from miraculous if it wasn't quite obvious already. it'll be a slow burn between alina, barry, kara and their romantic love interests, so just a lil heads up. we locking in for the long run.

i'm actually dedicated on focusing on this fic, which will most definitely be long since i'm planning on it spreading through phase two to phase four of the mcu timeline so i'm hoping there won't be slow updates.

barry and kara are literally platonic soulmates trying to co-parent their daughter, alina, through this whole madness. that's merely the plot lol.

anyway, i'm super excited to be back and write this fic fr. i hope you all will love it, and please don't be ghost reader. i love reading all your comments and they really motivate me to continue writing. no votes or comments are ever too many for me <3
