Well, a cool plot might be that Spider - Man's radioactive spider bite was actually a result of some magical experiment gone wrong in the wizarding world. Hermione investigates this and finds out that a dark wizard was trying to create a super - soldier. She and Spider - Man then have to work together to stop the dark wizard from creating more chaos. Also, they could start a friendship where Hermione teaches Spider - Man some basic spells and he shows her how to be more street - smart in his world.
A possible plot is that there is a threat that endangers both the wizarding world and Spider - Man's New York. Hermione and Spider - Man cross paths while trying to solve the mystery behind this threat. They find out that an ancient magical - scientific device has been activated by an evil force. Along the way, they learn from each other's skills. Hermione's vast knowledge of magic and Spider - Man's agility and web - slinging abilities combine to take on the bad guys. They also have to deal with the cultural differences between their two worlds, like Hermione being confused by the modern technology in Spider - Man's world and Spider - Man being amazed by the magic in hers.
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. Another could be a team - up between Miles and an older, more experienced Spider - Person from a different universe to face a new and powerful villain.
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. They have to figure out how to work together while also dealing with the chaos the villain is causing in different timelines. 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. Or perhaps Venom gets amnesia and Spider - Man has to convince him that they were once enemies but now need to work together. 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.
One idea could be that Spider - Man discovers a new villain who has a personal vendetta against him for something he unknowingly did in the past. This villain targets the people Spider - Man cares about, like Aunt May or Mary Jane, forcing him to go on a full - throttle revenge mission to protect them and clear his name.
