The Spider - Man harem fanfiction usually has a focus on character development within the context of the harem. Each female character has her own backstory and motives for being part of Spider - Man's life. It also often plays with different interpretations of the Spider - Man universe, creating new scenarios and storylines that revolve around his harem. For instance, some might change the power dynamics between Spider - Man and the female characters, leading to unique and interesting plot twists.
Gwen Stacy is an obvious choice. In different universes, she has different relationships with Spider - Man. Another could be Mary Jane. She has always been an important part of Spider - Man's life. Black Cat might also be in the harem as she has a complex and flirtatious relationship with Spider - Man in the comics.
One interesting concept could be the different relationships that Spider - Man forms with various characters in the harem. For example, his interactions with different versions of Gwen Stacy or Mary Jane could be explored in unique ways. Maybe there are stories where they all team up to fight villains together while also dealing with their complex feelings for Spider - Man.
Black Cat could be in the harem as well. She has a flirty and complex relationship with Spider - Man. Then there are other characters like Felicia Hardy who might be included. Her cat - burglar persona and her feelings for Spider - Man could make for an exciting addition to the group of characters in the fanfiction.
One common theme is the struggle of Peter Parker to keep his double life as Spider - Man and his relationships in the harem a secret. It's a classic superhero trope that adds a lot of drama.
One popular Spider - Man Marvel harem fanfiction is 'Spider's Web of Love'. It has an interesting take on bringing multiple characters into a romantic relationship with Spider - Man. The story is well - written and the interactions between the characters are engaging.
An anti - hero or a morally grey character might be the antagonist. This character could have a different view on relationships and superhero life. He convinces Spider Man that the harem is holding him back from achieving greater things. And Spider Man, being influenced, betrays the harem.
One possible plotline could be that Spider Man, perhaps due to some mind - control or misunderstanding, turns against the members of his harem. Maybe he starts working with a villain who convinces him that his relationships in the harem are a weakness. Another could be that he accidentally reveals secrets of the harem members, which they see as a betrayal.
Mary Jane Watson is very common. She has a long - standing relationship with Spider Man in the original comics, so she often appears in these fanfictions as part of the harem. Gwen Stacy is another one. Her tragic end in the comics makes her an interesting addition to the harem in fanfiction, as it gives room for different storylines to develop. Black Cat is also frequently included because of her flirty and complex relationship with Spider Man.
One common theme is the power dynamics. Naruto's ninja powers and Spider - Man's superhuman abilities play into how they interact with the characters in the harem. Another theme is the clash of different universes. Since Naruto is from a ninja - based world and Spider - Man from a more modern, superhero - filled one, seeing how these two worlds blend in the context of a harem story is quite common.
