In a fanfiction, Spider - Man could get lost in an alternate dimension during a mission. The Avengers then have to find a way to bring him back. While in the alternate dimension, Spider - Man meets different versions of the Avengers and has to fight his way through various challenges to return home.
Well, Tony Stark might be amused and a bit proud. He'd probably see the fanfiction as a testament to how much Spider - Man has grown under his mentorship. Steve Rogers might be a bit confused at first, but then he'd appreciate the creativity and the way it shows the bond within the team. Thor would likely find it all very entertaining and might even want to hear more stories about Spider - Man's adventures in this fictional take.
He could be a new recruit. The Avengers are always looking for new talent, and Spider - Man's abilities would be a great addition. He could start off as a bit of an outsider, trying to fit in with the more experienced heroes.
One idea could be a fanfiction where Spider - Man has to team up with the Avengers to stop a new villain that is specifically targeting his neighborhood in Queens. This would combine the street - level heroics of Spider - Man with the big - scale action of the Avengers.
One popular trope is the mentorship. Since Spider - Man has a connection with Tony Stark in the movie, fanfictions often expand on this. Another is the 'fish out of water' trope where Spider - Man is out of his comfort zone when dealing with the Avengers' big - scale operations.
Fanfictions sometimes create scenarios where Spider - Man from 'Homecoming' has to prove himself to the established Avengers. His youth and inexperience contrast with the more seasoned heroes. This can lead to interesting character development arcs, such as him learning from the Avengers' combat strategies and they in turn learning from his unique approach to fighting crime on a smaller scale.
Obviously, Spider - Man himself is a very popular character to focus on. His relatable character, with his high - school problems and superhero duties, makes for great fanfiction material.
A great fanfiction in this genre is 'Avengers' Movie Night'. In it, the Avengers gather to watch Spider - Man: Homecoming. It's full of humorous exchanges as they react to the movie. For instance, Clint Barton keeps making jokes about Peter's youthfulness.
One idea could be Spider - Man joining the Avengers on a mission to a far - off planet. He uses his agility and quick thinking to help the team out of tricky situations. Another could be a story where Spider - Man has to prove himself to the Avengers in a training exercise set up by Iron Man.
There might be a fanfiction where the Avengers turn the viewing of 'Spider - Man: Homecoming' into a training session for Peter. They pause the movie at different points to discuss what he could have done better and how to handle various situations. For example, Black Widow could be teaching him about stealth during a scene where Peter is sneaking around in the movie.
