A common theme is the clash of their personalities. Storm is often seen as noble and refined, while Logan is rough and gruff. Their married life might involve a lot of banter and learning to understand each other's differences. Another theme could be them facing threats together as a married couple, using their combined powers and skills.
Sure. A lot of fanfiction writers explore the concept of Storm and Logan being married in different ways. Some fanfics might take a more action - packed route, where their marriage is put to the test during battles or against common enemies. Others could be more character - study - like, delving deep into how their relationship would change after getting married, perhaps exploring their emotional growth and how they support each other in different situations.
Their relationship would likely become more intimate and committed. Having a baby together is a huge step, and they would have to rely on each other more. Logan might become more protective of Storm during her pregnancy, and Storm would probably be more patient with Logan's gruff ways as they both focus on the future of their family.
Another theme is their mutual respect for each other's powers. Logan respects Storm's control over the elements, and Storm respects Logan's healing and fighting abilities. This is often shown when they team up in fanfictions. They trust each other completely in combat situations because of this respect.
Well, one possible plot could be that Storm and Logan discover they're having a baby by accident. Maybe they initially struggle with the idea due to their complex lives as mutants. Logan might be worried about his past and how it could affect the child, while Storm could be concerned about how the X - Men will react. But as the pregnancy progresses, they grow closer and start preparing for the baby's arrival, building a nursery in the X - Mansion and sharing their hopes and fears with their mutant friends.
In some fanfictions, they might be. Fanfiction writers often like to create alternate storylines. It could be an interesting plot twist to have Logan and Rory's parents married. This could lead to all sorts of family dynamics and relationship changes for Logan and Rory.
Another one is 'Storm's Choice with Logan'. In this story, Storm is faced with a difficult decision that involves Logan. It's a more character - driven piece that really digs deep into their personalities and how they interact with each other in a tense situation.
A common theme is domestic bliss. Stories often show them enjoying simple pleasures at home, like cooking together or having movie nights. Another theme is dealing with past traumas. Since both Veronica and Logan have had rough pasts, fanfictions may explore how they support each other in getting over old wounds while being married.
They would become more protective of each other. Wolverine, who is usually a lone wolf, would be more open to relying on Storm, and Storm would be more assertive in keeping Wolverine out of unnecessary danger.
