Well, in some Emma Frost lemon fanfiction, the writers may create alternate universes where she has different roles. Maybe she's a leader in a world where mutants are the dominant species, and the story could revolve around her leadership challenges and how her character evolves. Also, her relationship with the younger mutants she sometimes mentors can be a central theme, showing her as a more nurturing figure than we might expect from her normal portrayal.
Well, one interesting story could be about their unexpected alliance. They might start off as rivals but then find common ground in protecting a young mutant. In this fanfiction, their relationship could be filled with witty banter and slowly evolving feelings. Another could focus on a time - travel scenario where they meet in a different era and have to work together to change the course of mutant history. There's also a possibility of a story where they are forced to team up against a powerful common enemy and during the process, discover new aspects of each other's personalities.
One interesting fanfiction could be about their relationship development in a post - apocalyptic world. In this story, they might have to rely on each other more than ever to survive, which could bring out new aspects of their characters and their bond.
Well, there might be a fanfiction where Emma Frost attends Hogwarts as an exchange student of sorts. She could introduce new ways of thinking and using mental abilities among the students. For example, she might teach some of the students how to better protect their minds from Legilimency, which is somewhat similar to her own telepathic defenses in her own universe. And Harry Potter could learn a great deal from her about mental strength.
A fanfiction with these two characters could be really creative. Spiderman's sense of responsibility and Emma Frost's leadership qualities could be in contrast or complement each other. In the story, they might team up to save a city or even the world. And the 'lemon' aspect could just be a way to add some emotional and romantic depth to their relationship, showing their more vulnerable and passionate sides.
The appeal might lie in the combination of two very different characters. Spiderman is the friendly neighborhood hero, while Emma Frost is a complex and often morally ambiguous character. In a lemon fanfiction, it could be exciting to see how their relationship develops romantically. Their different backgrounds and power sets make for an interesting mix.
I'm not sure specifically about 'lemon' fanfiction (which often implies inappropriate or adult - themed content). However, there are many regular Superman and Emma Frost fanfictions that can be found on popular fanfiction websites like Archive of Our Own. You can search for their crossovers there.
A common theme could be her relationship with other X - Men characters. For example, her interactions with Cyclops or Wolverine. Another theme might be her struggle with her powers and how she uses them in different situations in the fan - created stories. Also, her backstory as a rich and powerful mutant often plays a role in the fanfic themes.
A plot could involve Wolverine and Emma Frost in a time - travel adventure. They go back in time to prevent a catastrophic event that would wipe out mutants in the future. During this journey, they face challenges that test their loyalty to each other and their mutant kind. Or perhaps a story where Wolverine's healing factor is somehow linked to Emma Frost's diamond form, and they have to figure out how to control this new connection for the greater good. Also, a plot where they are on opposite sides at first in a mutant civil war but then realize they have more in common than they thought and switch sides together.
One great Emma Frost and Tony Stark fanfiction could be where they team up to face a common threat. Maybe a new mutant - technology hybrid villain. In such a story, their different powers and personalities would clash and then find a way to work together effectively.
One great 'oc x emma frost fanfiction' could be where the OC is a new mutant at the school.
