Stark - Civil War (MCU) - MC x Peter Parker

Everyone knows Tony Stark.

Genius. Billionaire. Avenger.

But almost no one knows about his daughter.

Sixteen-year-old Sienna Stark has spent her life surrounded by superheroes, sarcastic AI assistants, late-night lab experiments, and the world's most overprotective father. Training alongside the Avengers has always been her normal-even if her mysterious gravity powers are anything but.

She never expected the family she'd grown up with to turn against itself.

When the Sokovia Accords divide the Avengers, Sienna is forced to choose between the people she loves most. Every decision comes with consequences, every battle leaves another crack in the only home she's ever known, and for the first time, being Tony Stark's daughter isn't enough to protect her.

Then a witty kid from Queens swings into her life. Spiderman.

He's awkward, brilliant, and somehow manages to make her laugh in the middle of a war.

She has no idea that one meeting is about to change both of their lives forever.

As loyalties shatter and heroes become enemies, Sienna must discover who she wants to be-not just as Tony Stark's daughter, but as a hero in her own right.

Because sometimes the hardest battles aren't fought against villains...

They're fought against the people you call family.
