Maybe the cityscape is like a funhouse mirror version of New York. Buildings are all distorted and the streets are in strange patterns. Spider - Man would have to relearn how to get around the city. And his enemies could be hiding in places he'd never expect because of the strange layout. It would be a whole new environment for him to adapt to, and it would test his skills in a different way.
There could be a situation where the people he cares about have different personalities. Mary Jane might be really cold and distant instead of her warm and loving self. This would deeply affect Spider - Man on an emotional level. He'd have to figure out how to deal with these changes in the people he loves while also trying to find a way back to his normal world.
One possible aspect could be that in this fanfiction, Spider - Man enters a world 'through the looking glass' which is a distorted version of his own. Maybe the villains have different powers or the city looks completely strange. For example, the skyscrapers could be made of some sort of strange, elastic material that bends and twists, making it difficult for Spider - Man to swing around as he normally does.
In fanfiction, if Spider Man was experimented on, he might gain new powers. For example, the experiment could enhance his existing spider - like abilities to an extreme level, like being able to swing between buildings at supersonic speeds or having a much stronger spider - sense that can predict events hours in advance.
A 'Spider Man disappear' fanfiction could explore many aspects. For example, Peter Parker's friends and family would be deeply affected. MJ might be heartbroken and start her own investigation. Meanwhile, the scientific community in the story could be looking into the strange phenomenon of his disappearance. There could also be a sub - plot where a young fan of Spider Man decides to take matters into his own hands, inspired by the hero, and tries to find out what happened, even though he has no superpowers. This could show the impact Spider Man had on the city not just as a protector but also as an inspiration.
Maybe in the 2018 fanfiction, the 2023 Spider - Man meeting could be a reunion of all the Spider - Man versions from different universes. They might come together to fight a new and powerful villain that threatens all the universes.
They could exchange their experiences of being a superhero. Spider Man has been through a lot in his own world, and Spider Woman would have her own set of challenges. Sharing their stories could help them grow as heroes and also deepen their connection.
They might team up to fight a common enemy. In fanfiction, it's often about them combining their unique skills. Spider Gwen's acrobatic style and Spider Man's quick - wittedness would make for an awesome duo against villains like the Green Goblin or Doctor Octopus.
Perhaps he'd go back to the time when he first got his powers. He could see how his decisions at that time affected his life later on. He might also try to find out more about the origin of his powers, like if there was something more to the spider bite than he initially thought. This could lead to him having an even greater understanding of his abilities and how to use them more effectively.
Well, in such a fanfiction, Spider Man might initially be very suspicious of Loki. After all, Loki has a reputation for being a trickster. Maybe Loki would try to play some mind games with Spider Man, but Spider Man's quick wit and sense of humor would help him see through the tricks. They could end up teaming up against a common enemy, like an alien invasion that threatens both their worlds.
In this fanfiction, Spider Man might struggle to keep his identity a secret at school. He could have to deal with normal school stuff like exams and bullies while also being a superhero.
Well, it might show Spider - Man struggling not only with Venom physically but also with the emotional turmoil of being unmasked. His friends and family might be in danger, and he has to find a way to protect them while dealing with the public knowing who he is. Maybe he tries to convince the public that he's still on their side even though his identity is out.
