Maybe there's a powerful ancient artifact that has been stolen and is being used for evil purposes. This artifact has the power to disrupt the balance between different realms. Spiderman discovers some strange happenings in the city related to the artifact's power, like buildings randomly changing shape. Wonder Woman is also on the hunt for the artifact as it was stolen from a place under her protection. When they meet, Spiderman is initially in awe of Wonder Woman's strength and beauty. They team up, with Spiderman using his acrobatic skills to navigate through dangerous traps set up by the villains protecting the artifact, and Wonder Woman using her lasso of truth to find out where the artifact is hidden.
Lex Luthor could be a great villain. He could be after some technology in Spiderman's world that he wants to use to enhance his power in his own battles against Superman. At the same time, he might see Wonder Woman as a threat to his plans of world domination. He could use his intelligence to create complex traps and weapons. His corporate power would also allow him to manipulate situations in both the worlds of Spiderman and Wonder Woman.
Another possibility is that there is a villain who is stealing technology from Stark Industries (where Spiderman sometimes gets his tech) and ancient artifacts from Wonder Woman's homeland. They are both independently investigating and then cross paths and decide to work together to stop the thief.
Spiderman's agility and ability to climb walls combined with Wonder Woman's super strength could make them an unstoppable team. For example, Spiderman could use his web - slinging to quickly get Wonder Woman to high vantage points, from where she can use her strength and lasso to take on enemies. Or in a fight, Spiderman can dodge attacks and then Wonder Woman can follow up with her powerful punches.
There could be. Fanfiction writers often come up with creative crossovers. But if it's a 'lemon' fanfic, it might not be suitable for all audiences. There are other fanfics that explore the dynamic between Spiderman's quick - wittedness and Wonder Woman's strength in a more family - friendly way, like them teaming up against a common villain.
One interesting crossover could be a story where Spiderman and Wonder Woman team up to fight a common enemy like Darkseid. Spiderman's agility and web - slinging skills combined with Wonder Woman's strength and lasso of truth would make for an exciting battle.
Maybe in the fanfiction, they are brought together by a common enemy who is a threat to both their worlds. As they team up, they discover they have more in common than they thought. Wonder Woman is impressed by Spiderman's sense of responsibility and his ability to always keep fighting no matter the odds. Spiderman is in awe of Wonder Woman's strength and grace. Their relationship develops, and they decide to get married. After marriage, they balance their personal lives and hero duties, and their union brings a new era of peace and cooperation between their respective hero communities.
One common theme is the 'opposites attract' concept. Spiderman is more of a street - level hero, while Wonder Woman is from a mythological background. Their different origins and powers make for an interesting dynamic. Another theme could be the 'forbidden love' aspect, as they belong to different superhero groups or universes in the original comics.
There is some. Check FanFiction.net as well. However, keep in mind that the quality can vary a great deal. Some stories might be more action - based, where they team up against a common enemy and feelings develop during the adventure. Others could be more about the slow - burn of their relationship, delving into their emotional connection.
A cool scenario would be a battle royale - style crossover where Wonder Woman is brought into the Marvel universe to participate in a tournament. She has to fight against various Marvel heroes and villains, like Thor and Loki. As she progresses, she discovers that the real mastermind behind the tournament is trying to use the chaos to open a portal to another dimension. Along the way, she forms alliances with some of the Marvel characters and together they try to stop the evil plan.
