Maybe Peter Parker has his own distinct view of Steve. He might feel that fanfiction often distorts Steve's real character or the relationships in the original story, so he doesn't like it.
Maybe Peter doesn't like the way Steve is portrayed in fanfiction. Some fanfictions might deviate too much from the original character, and Peter prefers the official version of Steve.
Peter might not be a fan of the genre of fanfiction in general. He could prefer original works and find fanfiction, especially about Steve, to be unoriginal or too derivative. Also, it could be that he has had some bad experiences reading poorly - written Steve fanfiction in the past that has put him off completely.
Perhaps Steve in the fanfiction was involved in a cover - up of some sort that affected Peter. Say, Steve knew about a threat coming towards Peter but didn't tell him in time because he thought Peter couldn't handle it. When Peter found out, he felt betrayed and thus couldn't forgive Steve. Also, if Steve accidentally caused harm to one of Peter's friends or allies while on a mission, that could be a major factor in Peter's unforgiveness.
It might start with a small incident where Steve dismisses Peter's ideas or concerns. This initial rift then grows as more events unfold. For example, Steve might take credit for something Peter did, which makes Peter angry and less likely to forgive.
Yes, there are likely fanfictions with this concept. Fanfiction writers often come up with creative and unexpected family relationships between characters. They might explore how Peter Parker, with his intelligence and spidey - sense, could be related to Steve Rogers, the paragon of virtue. This could involve a complex backstory about how their family lines connected over the years, perhaps with some time - travel or alternate universe elements.
Sure. Fanfiction is a vast world full of all kinds of wild ideas. In a 'Peter Parker is Steve Rogers son' fanfic, it could show Steve as a father figure guiding Peter in both his normal life and superhero duties. Maybe Steve has to deal with Peter's teenage angst while also training him to be a better hero, like passing on his values of justice and self - sacrifice.
Another good one is 'Mentorship and Beyond'. This fanfic delves deep into how Steve's values influence Peter. It also shows Peter's growth under Steve's guidance.
The theme of friendship also often emerges. Despite the mentor - mentee relationship, Steve and Peter develop a deep friendship. They bond over shared experiences of having to keep their identities secret, of fighting bad guys, and of trying to do the right thing in a complex world. This friendship is often explored in different ways, such as through them having heart - to - heart conversations or going on adventures together.
