Summer Upstate (Avengers x Male OC)

Nicholas Daniels gets dusted. After being blipped and disappearing for 5 years, he spends a month in a shelter before authorities could track down one of his parents.
Turns out his dad moved upstate and started a whole new family with a woman who's like 10 years younger than him.
The summer before he goes back to school is spent avoiding his resentful father, uncomfortable new step mom and new younger siblings.

Its in the woods near a secluded cabin where he meets Peter Parker and the Stark family. They start becoming friends and maybe there's more to Nicholas Daniels then anyone's letting on.

(Basically the Avengers take in a struggling super-kid in while recovering from the events of endgame but this time around Tony and Natasha are still alive because I can't cope)
