Spiderman is the key, of course. In addition to the well - known female characters from the Spider - Man universe, there might be other characters from the Marvel world who cross paths with him and end up in the harem. For instance, Black Cat could be a likely candidate. She has that alluring and mysterious personality that would fit well in this kind of scenario. Also, characters from different dimensions or alternate universes could be brought in, adding an element of the unexpected to the harem and the overall story.
One interesting plotline could be Spiderman having to balance his superhero duties with the complex relationships in the harem. Maybe he has to keep his identity secret from some of the harem members while also protecting them from villains.
There are quite a few out there. Some might focus on how Spider - Man interacts with different DC characters in a harem - like setting. For example, he could be in a world where he meets various female DC characters and forms unique relationships with them. You might find some really creative stories if you dig deep enough into the fanfiction community.
One common theme is the clash of universes. Since Spider - Man is from Marvel and DC characters are from a different universe, there's often exploration of how their different powers and personalities interact in a harem setting.
Spiderman's sense of responsibility may expand. If he's in a harem with Avengers like Iron Man or Captain America, he might take on more global - scale threats. His character also becomes more adaptable as he has to juggle different personalities and powers within the harem. He might learn new ways to use his own powers from his partners. For instance, if he's with Scarlet Witch, he could learn about different dimensions of power that he hadn't considered before. And he has to be more empathetic to understand the needs and feelings of all his partners in the harem.
In some fanfictions, there could be other supporting characters as well. For example, Mary Jane might make an appearance in the Spiderman x 23 fanfiction. She could be a source of emotional support for Spiderman or even get involved in the action in some way. Also, characters from X - 23's world like Wolverine could potentially show up and add more depth to the story.
A plot could revolve around a new villain that targets the Justice League, especially because of Spiderman's presence in the harem. The villain might see Spiderman as a weak link or an interesting addition to their plans. So, the story would be about the Justice League, including Spiderman, coming together to defeat this threat. Along the way, Spiderman's relationships with the harem members like Hawkgirl and Cyborg could evolve, with some characters growing closer and others having some misunderstandings.
One popular storyline might involve Spiderman having to balance his relationships with different Avengers while also dealing with his superhero duties. For example, he could be in a relationship with Black Widow, who helps him understand the darker side of the superhero world, and at the same time be friends - with - benefits with Scarlet Witch, who adds a magical and mysterious element to his life. Another could be where he forms a polyamorous relationship with some of the younger Avengers like Shuri and Kate Bishop, and they all work together to take on new threats in the Marvel universe.
One popular example could be those where Spiderman has a harem consisting of Mary Jane, Gwen Stacy, and Black Cat. In these fanfictions, the author often weaves different storylines around how Spiderman manages his relationships with these different characters at the same time. They might show his superhero duties interfering with his love life, and how the women in his harem support or are frustrated by his double - life.
It could be really interesting. Spiderman in the Justice League setting would bring a different dynamic. In a harem scenario, there could be various relationships with other Justice League members. Maybe he'd have a close bond with Wonder Woman, sharing his street - level hero insights with her more high - concept heroism. And with Flash, they could have some fun, friendly rivalries while also being part of this harem - like group.
