In some fanfictions, Peter could be hurt physically during battles. For example, he might take more severe hits from villains than in the movie. This could be because the writers want to explore his vulnerability and the limits of his powers.
Well, often in 'Spider - Man: Homecoming' fanfiction, Peter's Spider - Sense is used in creative ways. It could be tied to his growing up process. As he matures, he learns to better control and interpret his Spider - Sense. Maybe it starts to work differently around his friends, like it gives a softer signal when they playfully surprise him compared to a full - on danger alert.
The superfamily could interact with Spider - Man in a more helpful way. For instance, if Spider - Man is injured during a fight, Peter's family in the superfamily could offer him shelter and medical help. They might also use their own unique skills (maybe one is good at making gadgets) to help Spider - Man improve his suit or his web - slinging abilities.
Well, it happened when Peter was on a school field trip. A radioactive spider bit him, and that's what triggered the transformation. His newfound powers led him to take on the identity of Spider-Man to fight crime and protect the innocent.
Probably not. Most fans love to see Spider - Man in his heroic element, swinging around and saving the day. Fanfictions that involve him getting beaten up go against the typical image of him being a strong and capable hero. So, it's less likely that there are popular ones with this theme.
One great fanfiction idea could be that Gwen discovers Peter's secret identity in a really unexpected way. Maybe she stumbles upon his Spider - Man suit while looking for something in his room. This would create a lot of drama and tension between them as she has to decide what to do with this knowledge.
