A fanfiction could explore what would happen if Spider - Man joined the Avengers right after the events of Homecoming. It could detail his struggles to fit in with the more experienced heroes, deal with their different personalities, and still maintain his own identity as a friendly neighborhood Spider - Man.
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.
Perhaps a fanfiction where a technology from the Avengers gets into the wrong hands in Spider - Man's world. He then has to figure out how to stop the chaos it causes, while also trying to keep his secret identity intact. This would create a lot of interesting scenarios as he tries to solve the problem without getting too much attention from the Avengers.
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.
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.
One idea could be a crossover with the X - Men. Spider - Man could find himself in the middle of a battle between the X - Men and some common enemy, like the Sinister Six. He'd have to figure out how to work with mutants, which is a whole new experience for him. Another idea is a crossover with the Fantastic Four. Maybe Spider - Man gets caught up in one of their space - related adventures. Reed Richards could be fascinated by his web - shooters and try to study them, while Spider - Man would be in awe of their super - scientific gadgets.
There could be a fanfiction where the Avengers are watching Spider - Man: Homecoming as a team - building exercise. As they watch, they start to discuss how they can incorporate some of Peter's methods into their own teamwork. Thor might be a bit clueless about some of the high - tech aspects of Peter's suit, but he's still entertained by the action. And Bruce Banner could be making scientific speculations about the web - shooters in between popcorn bites.
A great plot idea could be that the symbiote actually has a mind of its own and it's trying to find a way back to its home planet. It uses Spider - Man as a host to build a device to communicate with its home. Meanwhile, Spider - Man is struggling to keep his identity and life in order while dealing with the symbiote's demands. Also, the symbiote could infect other people in the city, creating a group of symbiote - controlled minions that Spider - Man has to fight. This would add a whole new level of danger to the story.
In a fanfiction, Gwen Stacy could be a time - traveler who ends up in the 'Spider - Man Homecoming' era. She meets Peter Parker and realizes that he's on a path that could lead to a very dark future for the city. So, she decides to use her knowledge from the future to change things. This would involve her teaching Peter new combat techniques and helping him make better decisions as Spider - Man.
One idea could be exploring Peter Parker's struggle to balance his normal high school life with his increased responsibilities as Spider - Man. Maybe he starts to get distracted in class more often because he's up all night patrolling the city.
One idea could be an OC who is a new student at Peter's school and has a hidden power related to technology. They end up helping Spider - Man with a villain who is hacking into all the city's tech systems.
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.
Perhaps in a fanfiction, Venom is actually a creation of one of the villains in Homecoming who wants to use it to defeat Spider - Man. But the symbiote has a mind of its own and instead starts to have an odd connection with Spider - Man, leading to a complex relationship where they have to figure out if they can trust each other.
