He might get a hamster. It's small and cute, and Peter could keep it in his room. He would have to make sure it's safe when he's out being Spider - Man. The hamster could provide some light - hearted moments in the fanfiction, like when it runs around in its little wheel while Peter is trying to study.
A spider. Since he has a connection to spiders already, it would be a very symbolic pet. It could be a super - smart spider that helps him in some way, like by spinning special webs that can detect intruders or by giving him clues about where the bad guys are hiding.
Peter could end up with a fish. He would need to take care of its tank, clean it regularly. The fish could have a unique color or pattern that is related to his Spider - Man identity in some way. Maybe the fish glows in the dark like some of his web - shooting devices.
Peter could get a dog. A loyal dog would be a great companion for him, following him around during his daily life and even being a sort of sidekick. It could sense danger and bark to alert Peter when something was wrong.
He might use his spider - powers to outperform in Quidditch. His agility could make him an excellent seeker, zipping through the air to catch the golden snitch much faster than others.
Well, one idea could be a time travel fanfic where May and Peter go back in time to prevent a tragedy. Or maybe a story where May discovers Peter's secret and helps him in a unique way.
If the situation is more serious, Peter Parker would be very respectful. He would listen carefully to the president's requests and do his best to fulfill them. For example, if the president asks him to investigate a strange occurrence that seems to have super - power related elements, Peter would swing into action, reporting back to the president with all the details he has gathered, just like a real - life agent would do.
The Avengers might have a range of reactions. Tony Stark would probably be amused and might make some sarcastic comments about how the fanfiction portrays Peter. Steve Rogers would be a bit more confused at first, not fully understanding the concept but then find the positive portrayals of Peter endearing. Thor would likely think it's a strange Midgardian thing but be entertained by the stories that show Peter as a heroic figure.
Iron Man, on the other hand, might be more direct. He could use his technology to track Peter's actions and confront him. He might threaten to expose Peter's identity if he doesn't stop. And Thor would probably be angry at first. He values his fans a great deal and seeing Peter bully them would make him want to use his hammer to teach Peter a lesson, but then he would also try to understand the situation.
In fanfiction, Peter Parker might experiment on various things. He could be experimenting on new web - shooting formulas to enhance his abilities as Spider - Man. Maybe he's trying out different ways to use his spider - sense in combat situations. It all depends on the creativity of the fanfiction writers.
Slytherin is also a possibility. He has to be resourceful to make his own web - shooters and manage his double life. In Hogwarts, he might use his cunning to get out of tricky situations, like when dealing with the mysteries and politics within the school. However, his moral compass would likely keep him from the more negative aspects of Slytherin. He would probably be a different kind of Slytherin, one who uses his wits for good.
I think Thor could be really excited too. Thor loves a good warrior and Peter, with his spider - like abilities, would be an interesting addition to his view of heroes. Thor might be amused by Peter's small - scale heroics compared to his own grand battles and would enjoy seeing Peter's potential grow.
Maybe Thor. Peter has never seen someone as powerful as Thor with his hammer and god - like abilities. Thor's larger - than - life presence could be really fascinating for Peter.
