In this fanfiction, Peter Parker doing the snap could be a very different scenario compared to what we saw in the movies. He could be tricked into doing it by a villain who wants to cause chaos. Once he snaps, it might not have the expected results. Instead of simply eradicating half of the life in the universe, it could create some sort of rift or imbalance. Peter then has to find a way to fix this new problem, all while dealing with the guilt of what he has done.
Peter Parker would be central. Additionally, Doctor Strange could play a role. Since he has knowledge of the future and different timelines, he might try to intervene and prevent Peter from doing the snap. Then there are the villains. Maybe Mysterio, who has a grudge against Peter, could try to manipulate the situation to make Peter snap in a way that benefits him. And of course, Aunt May would be there in some capacity, perhaps as the voice of reason for Peter.
One possible plot could be that Peter discovers he has Asgardian blood through some magical accident. He then starts to have visions of Asgard and is eventually drawn there. Once in Asgard, he has to prove himself worthy, just like Thor did with Mjolnir, but with his own unique set of skills as Spider - Man.
Well, it could be about Peter Parker getting trapped in subspace while on a mission. He might encounter strange entities there that he has to outwit to find his way back. Maybe he discovers some new powers or abilities while in subspace that help him in future battles in the normal world.
A plot could involve Peter going on a long - distance mission with the Avengers. They're in a quinjet or some other vehicle. Peter starts feeling carsick because of the unfamiliar motion. His carsickness becomes a bit of a problem during the mission as it affects his performance. So, the other Avengers have to figure out how to deal with it while also handling the mission at hand. It could add a touch of humor and a new dynamic to the story.
Well, the plot could involve Peter Parker using his scientific knowledge to create a revolutionary product that makes him extremely wealthy overnight. With his new wealth, he decides to fund various projects in New York to fight crime more effectively. He might also face new enemies who are after his money or try to use his wealth for their own evil purposes. And his personal life would change too, as he'd be living a more luxurious lifestyle while still trying to keep his identity as Spider - Man a secret.
In this type of fanfiction, the plot could start with Peter discovering his immortality after a near - death experience. He realizes that he can't die no matter what. This makes him question his own identity and his role as Spider - Man. He decides to travel the world, learning different fighting techniques and knowledge. Along the way, he still tries to protect the innocent. But he also has to deal with the fact that he will outlive everyone he loves. He might even try to find a way to reverse his immortality at some point.
One possible plot could be that Peter Parker, while on a school trip or some scientific research in space (maybe with Stark tech), accidentally stumbles upon Peter Quill and the Guardians of the Galaxy. They initially have a bit of a misunderstanding as their ways of doing things are quite different. Parker is used to the more down - to - earth (literally) problems in New York, while Quill is dealing with intergalactic threats. But they soon realize they can learn from each other. Parker could teach Quill about the latest Earth - based technology, and Quill could show Parker the wonders of the galaxy.
One possible plot could be that Peter Parker is sent on a school exchange program to Korea. There, he has to use his Korean skills to communicate with his host family, make new friends, and also fight crime as Spider - Man in a new environment. Maybe he discovers a new villain who has some connection to Korean mythology or technology.
Well, it could be a really wacky plot. Maybe some sort of strange scientific experiment gone wrong that gives Peter Parker the ability to lay eggs. And then he has to figure out how to deal with this new and unexpected situation while still being Spider - Man. He might have to hide it from his friends and enemies alike.
Well, it could be about the challenges and joys of Peter Parker dealing with a pregnant situation. Maybe it focuses on how he prepares for fatherhood while still being Spider - Man.
