One idea could be exploring a new villain that is created from a scientific experiment gone wrong in Oscorp. This villain could have powers related to electricity and pose a new threat to Spider - Man.
Perhaps a fanfiction could explore an alternate universe where Peter Parker's parents are still alive. This would change his dynamic, as he would have their guidance and support, and might even have different priorities as Spider - Man.
Another interesting concept could be having Spider - Man lose his powers temporarily. This would force him to rely on his intelligence and his relationships with his friends, like Gwen Stacy or Harry Osborn, in new ways to still protect the city.
A crossover with the Avengers is also great. Picture Spider - Man having to prove himself to the more established heroes like Iron Man and Captain America. He could bring his unique street - level hero skills to a big - scale Avengers mission.
A great plot for Amazing Spider - Man fanfiction could be a time - travel story. Spider - Man could be sent back in time to the era when his powers first emerged. He could then use his knowledge of the future to prevent some of the tragedies that occurred in his past, like the death of Uncle Ben. Or, he could be sent to a future where New York has become a dystopia, and he has to find a way to fix it and return to his own time.
Maybe in the fanfiction, Spider - Man discovers a secret connection between his powers and an ancient Asgardian artifact. The Avengers, especially Thor, would be intrigued. They then embark on a journey to figure out how this connection could either save or endanger the world. Spider - Man would have to balance his normal life and this new discovery with the Avengers.
One plot idea could be that Gwen discovers a new superpower that she has to learn to control, and Peter helps her through the process. This could add a new dynamic to their relationship as they both have different powers and ways of handling them.
A plot could involve Harry getting powers as well, not just from the Goblin formula but in a different way related to some Oscorp experiment. He and Peter then have to figure out how to control their powers together and face a new supervillain created by Oscorp's misdeeds. It would add a new dynamic to their relationship as they both struggle with their newfound abilities.
One idea could be Mary Jane starting her own investigative journalism project related to Spider - Man's enemies. This would put her in danger and force Spider - Man to protect her while also trying to keep his identity a secret from her new inquiries.
Maybe Spider - Man discovers a new threat that the Avengers have overlooked. He then tries to convince them of the danger, facing skepticism at first but eventually winning them over with his tenacity and evidence. For example, he could find a hidden group of villains planning to use a new type of technology to take over the world.
One idea could be exploring the backstories of the different Spider - People in more detail. For example, how did Peni Parker really come to terms with her role as Spider - Woman in her own dimension. Another could be a crossover within the Spider - Verse, like what if Miles Morales and Gwen Stacy teamed up to face a new villain that was causing chaos across multiple dimensions.
There could be a lot of drama in the fanfiction related to the spider armor. For example, the public might react differently to this new armored version of Spider - Man. Some might see it as a sign of him becoming too militarized, while others might see it as a necessary upgrade. The armor could also be a target for villains who want to steal its technology for their own evil purposes.
One idea could be exploring the backstories of the different Spider - People more in - depth. For example, Peni Parker's relationship with her father and how it influenced her becoming Spider - Woman. Another could be a story where all the Spider - People have to team up against a new villain that is specifically targeting their multiverse connection. Maybe a villain who can disrupt the portals between their worlds.
