**Tony Stark always has a backup plan.**
When the Avengers spend hours stuck on a problem that refuses to cooperate, Tony casually mentions that he has someone who might be able to help.
Naturally, everyone assumes he's talking about another scientist.
They are very, very wrong.
Because Tony's backup isn't another genius billionaire, a government specialist, or even an adult.
It's a barely-thirteen-year-old boy who appears downstairs in the middle of the night, still half-asleep, clutching a teddy bear-and completely comfortable being carried in Tony Stark's arms.
Peter Parker is Tony's secret little genius, his trusted backup, and, apparently, someone Tony has been quietly raising for the past two years.
The Avengers just never knew.
Now they have to figure out how to process the fact that Tony Stark has a kid, Peter can solve problems they've been struggling with for hours, and Tony turns into the softest, most protective dad imaginable the second Peter is around.
What starts as one desperate call for backup becomes something none of them expected:
**a family.**
And Peter?
He's not just Tony's backup.
He's Tony's kid. ❤️
