Perhaps a story where Cosmic Spider - Man has to deal with the consequences of his actions in the cosmic realm affecting his life on Earth.

A plot where Cosmic Spider - Man teams up with other cosmic entities to fight a powerful, universe - threatening villain. It could involve complex power dynamics and epic battles across galaxies.

In some fanfictions, Spider - Man might gain the ability to teleport across the cosmos. This could lead to him exploring different galaxies and encountering alien species that are both friendly and hostile. He could use his spider - sense in new ways, like detecting threats from across the universe.
One idea could be exploring the different Spider - People's home universes in more detail. For example, showing what Miles Morales' daily life in his universe was like before becoming Spider - Man.

Perhaps there's a fanfiction where Spider Man and Spider Gwen accidentally swap powers. They have to learn how to use each other's abilities to fight crime. This would lead to some really funny and also challenging situations as they get used to different ways of web - slinging and sensing danger.
One plot idea could be that Spider Man and Spider Woman team up to fight a new supervillain who has the power to manipulate time.

Another could be a story where they get trapped in an alternate dimension and have to find a way back home while facing strange new enemies. Maybe there's a plot where they start to have feelings for each other but are afraid it will interfere with their superhero duties.
Maybe in the fanfiction, Spider - Gwen gets lost in the future where Spider - Man 2099 exists. He has to help her get back to her own time while also protecting his own version of New York from the chaos her presence might bring. They could learn from each other's fighting styles and develop a unique bond in the process.
Perhaps in a fanfiction, the Raft is under a siege by an unknown force. Spider - Man, despite being a prisoner, decides to help defend it. He teams up with some of the more morally ambiguous inmates. Together, they have to overcome their differences and fight off the attackers while also dealing with the internal power struggles and security issues within the Raft.
One idea could be exploring the relationship between Spider - Man 2099 and other superheroes in the future. Maybe he teams up with a new group of heroes to fight a powerful villain who threatens the entire city.
One plot idea could be Spider Man having to face a powerful new villain all by himself in a post - apocalyptic New York. The city is in ruins, and he has no backup from the Avengers or other heroes. He has to rely on his wits and his web - slinging skills more than ever.
Well, a cool plot could be that there's a scientific experiment gone wrong that fuses Venom and Spider - Man's powers in an unexpected way. They have to figure out how to control these new combined abilities while also dealing with villains who want to steal their power source.

There could also be a story where Venom's offspring has a different relationship with Spider - Man, like it's more of an anti - hero sidekick.
One idea could be Spider Man having to team up with his greatest villains to fight a common enemy from another dimension. This would force him to put aside his differences and find a way to work with the likes of Green Goblin and Doctor Octopus.
