It could be for a bet or a dare. Peter's friends dared him to wear Tony's clothes to school for a day. Peter, not one to back down from a challenge, takes on the dare. He shows up at school in Tony's clothes, feeling a bit self - conscious at first but then starts to embrace the whole situation and even has some fun with it, like pretending to be Tony for a while.
Peter might get mistaken for Tony. If Tony is popular or has a certain reputation, Peter could find himself getting the same kind of attention. Some people might come up to him thinking he's Tony and ask him about things that only Tony would know. This could lead to some really awkward or hilarious moments as Peter tries to either play along or quickly correct the misunderstanding.
One possible scenario could be that Stiles accidentally grabs Peter's clothes thinking they are his own. Maybe he's in a hurry to get dressed and doesn't notice until he's out and about. It could lead to some comical moments as people react to him wearing Peter's distinct style.
I think Rhodey would be a likely character. He was Tony's close friend, so he would be involved in verifying Peter's claim and guiding him. Also, Aunt May could play an important role. She has raised Peter and now has to come to terms with his new identity. And there could be some other Avengers like Natasha or Clint who knew Tony well and could offer their perspectives on this new family revelation.
There could be. Fanfiction is a vast world full of various creative ideas. Writers might be attracted to the idea of Tony and Pepper being Peter's parents as it can bring new storylines, such as how they would raise Peter in the Stark household, with all the technology and wealth at their disposal. It could also explore how Peter's powers would be incorporated into their family dynamic.
In this fanfiction concept, it could bring a whole new dynamic to the Marvel universe. Peter being their son would mean he has a very different upbringing. He might inherit Tony's genius and Pepper's business acumen. There could be stories about him growing up in the Stark mansion, having access to all of Tony's technology from a young age. And perhaps he'd be trained by Tony in both technology and self - defense much earlier, leading to a Peter who is even more formidable than in the original storylines.
In many fanfictions where Peter is Tony's biological son, it can lead to some really interesting storylines. For example, it might change the dynamic of their relationship in the Marvel universe. Instead of the mentor - mentee relationship we see in the original, it could be a more father - son bond filled with family drama and deeper emotional connections. Maybe Peter would inherit more of Tony's traits and skills in a more direct way, and there could be a whole new set of adventures centered around their family relationship.
There are a great number of fanfictions where Tony Stark is Peter Parker's father. This is because their relationship in the official Marvel universe is already somewhat of a mentor - mentee one. Fanfiction writers take it a step further. For example, in some stories, Tony discovers he has a biological connection to Peter. In others, it's more of an emotional father - son bond that develops over time through shared experiences, like fighting villains together or working on new tech in the Stark labs.
Maybe it's a dare. His friends could have dared him to wear Tony's clothes for a day and he reluctantly agrees. And as he wears them, he realizes there's more to Tony's style than he thought.
Maybe Peter inherits Tony's high - tech gadgets. For example, he could get access to some of Tony's Iron Man tech, which would be a huge deal. This could set him on a new path in his superhero journey, perhaps allowing him to upgrade his own suit or develop new abilities.
