Well, the plot could involve Stiles growing up in the shadow of Tony Stark. He might be sent to a high - end school where he has to deal with other kids of famous people. But his love for solving mysteries in Beacon Hills would still be there. Tony, on the other hand, might not understand Stiles' fascination with the supernatural at first. However, as the story progresses, they could learn from each other. Stiles could teach Tony about loyalty and friendship in a small - town way, and Tony could show Stiles how to use his resources more effectively.
The story could start with Stiles finding out that Tony Stark is his father. This revelation would turn his world upside down. He'd be introduced to the world of the Avengers and all the high - tech stuff. But he'd also be worried about leaving his friends behind. In this fanfiction, there could be a plot where an enemy targets Stiles to get to Tony. So, they have to work together to protect each other. Stiles could use his quick thinking and knowledge of the supernatural, while Tony uses his Iron Man technology. This would be a great blend of two different universes.
