One plot idea could be Peter and Live Wire facing a new supervillain together as a married couple. They'd have to combine their powers and their relationship skills to defeat the foe. Another could be them trying to keep their identities secret from the public while also dealing with the normal married life things like bills and family visits.
A possible plot for this fanfiction could involve Peter Parker and Live Wire starting a family. Since they both have superpowers, they would need to figure out how to raise their children with powers in a world that may not be fully accepting. They could also face challenges within their marriage due to their different backgrounds and responsibilities as superheroes. Maybe Peter is more used to working alone, while Live Wire is part of a team, and they have to learn to compromise and support each other in their superhero endeavors while being a married couple.
Well, a really cool plot might be that they are married but come from different dimensions. They then have to deal with the challenges of living in a new world while also maintaining their relationship. For example, Live Wire might have trouble adjusting to the more low - key lifestyle in Peter's world at first. Or perhaps they discover a threat that could destroy both their dimensions and they must work together, using their unique powers and the strength of their marriage, to save both worlds.
A new supervillain created specifically for this fanfiction could be the main antagonist. This villain could have the power to disrupt the electrical signals that Live Wire uses, and also have some way to counter Peter's spider - sense. Maybe this villain has a vendetta against superheroes in general and sees their marriage as a symbol of superheroes getting too comfortable and powerful.
A possible plot is that an old enemy of Peter discovers his relationship with Mystic and tries to use her to get to him. This could lead to a race against time for Peter to save her. Also, their marriage could be a source of strength for both of them. Mystic could use her powers to create illusions to help Peter in his crime - fighting, and in return, Peter protects her from the dark forces that are interested in her powers. They could also go on adventures together, exploring different dimensions where Mystic's powers are enhanced or different versions of Peter exist.
Some fanfictions might focus on the cultural differences between them. Peter is from a more normal human upbringing in terms of family and society, while Laura has a very different experience. Their marriage could be a journey of understanding and accepting each other's cultures. For example, how they celebrate holidays or deal with family traditions. This can create a lot of interesting character interactions and story development.
Maybe Peter discovers Marinette's Ladybug identity when he's in Paris on a mission. He initially mistakes her for a threat but then realizes she's a hero too. They start training together and sharing their experiences of being young superheroes. Marinette helps Peter with his stealth skills, which are useful for his Spider - Man activities, and Peter shows Marinette some new ways to use her yoyo in combat. This could lead to a romantic relationship as they grow closer through their shared superheroics.
One possible plot idea could be that Peter Parker meets a superfan who he ends up marrying in an unexpected turn of events. Maybe they initially bond over his superhero adventures and as they get to know each other better, love blossoms. Their relationship could then face challenges like keeping his identity a secret from the public while being in a high - profile relationship.

One plot idea could be them facing a new supervillain together while also dealing with the typical married issues like who does the dishes or takes out the trash. Another could be that they're trying to keep their relationship a secret from the public eye because of all the attention it would draw.
If we consider Peter Parker and Supergirl. Supergirl is a powerful being from Krypton. Their marriage could involve Peter having to deal with her super - strength and also the fact that she has a different set of values coming from an alien culture. They could work together to protect both Metropolis and New York, combining their powers and intelligence.
One possible plot could be that they meet during a multiverse - related event.
