Another idea is a time - travel fanfiction. Spider - Man could be sent back in time to when his Uncle Ben was still alive. He would have the chance to prevent his uncle's death, but he'd also have to deal with the consequences of changing the timeline, like how it might affect his own development as a hero.
A possible plot is that Spider - Man and Spider - Gwen discover that they are related in some unexpected way through a long - lost family connection. This revelation shakes their relationship as they struggle to come to terms with it. They could also be pitted against each other by a powerful enemy who uses mind - control, and they have to break free and remember their true friendship.
One interesting plot idea could be that Spider Girl and Spiderman team up to take on a new supervillain who has the power to control time. They have to figure out how to defeat the villain while also dealing with the chaos caused by the time - warping powers. Another idea is that Spider Girl discovers a secret about Spiderman's past that changes their relationship. Maybe she finds out about an old enemy he had that is now back and they have to face it together.
One idea could be that different versions of Spiderman from across the multiverse team up to fight a common enemy that can travel between dimensions and is threatening all their worlds. For example, a powerful symbiote - like creature that has the ability to absorb the powers of each Spiderman it defeats.
One idea could be that Spiderman 2099 has to team up with a group of rebels from a future dystopia to take down a powerful corporation that controls the city. They might face advanced technology and dangerous enforcers.

One idea could be exploring what would happen if Spider - Man had to team up with a villain to stop a greater threat. For example, partnering with Doctor Octopus to take on an alien invasion.
One idea could be that Spider - Man has to face a new villain who has the power to manipulate his darkest fears and turn them into reality. Another could be a version where Spider - Man is wrongly accused of a major crime and has to clear his name while also dealing with the city turning against him.
A cool plot could be that there is a glitch in the game world that starts causing real - world disasters. Spiderman has to figure out how to fix the glitch by going deeper into the game code, all while still dealing with his regular villains.
For a 'Spiderman into the Spider - Verse fanfic', you could have a plot where the Spot, who has been working on a new super - weapon in secret, manages to open portals to multiple universes all at once and unleashes a horde of minor villains from each. The Spider - People from different universes have to band together not only to fight these villains but also to close the portals. There could be a sub - plot about a relationship developing between two Spider - People from very different universes, like one from a steampunk world and another from a world of magic. This relationship could add an interesting emotional layer to the story as they struggle to save the multiverse.
It's not strange at all. Fanfiction is a form of fan expression, and as the subject of these stories, Spiderman would have a unique perspective. He might be interested in the different interpretations of his powers, relationships, and adventures. It could also be a way for him to understand the hopes and dreams that fans have for his character. Plus, it could be a fun pastime for him, something different from his usual crime - fighting routine.
