It could be about how they first realized their feelings for each other. Maybe during an adventure, they find themselves relying on each other more and more, which eventually leads to their marriage.
You can try looking on fanfiction websites such as Archive of Our Own or FanFiction.net. They usually have a large collection of fan - created stories including ones about Rouge and Knuckles getting married.
In fanfiction, Knuckles is often depicted as a strong and stoic character. He's known for his loyalty to his duties, like guarding the Master Emerald. Rouge, on the other hand, is usually portrayed as a sly and cunning character, with her thieving skills being a prominent part of her character. Their interactions can range from friendly banter to tense rivalries, depending on the plot of the fanfiction.
In Knuckles and Rouge kiss fanfiction, a common plot is the discovery plot. They discover something about each other that makes them see each other in a new light, leading to a kiss. Another plot is the adventure - induced - love plot. They go on an adventure together, face many challenges, and their shared experiences bring them closer until they kiss. There is also the self - discovery plot. Through their relationship with each other, they learn more about themselves, and the kiss is a moment of realization and connection.
The fanfic could be centered around a powerful Halloween artifact that is said to grant great power. Rouge wants it for her collection and power - up, Knuckles wants to protect it as it might be dangerous in the wrong hands, and Shadow wants to study it. This leads to a complex situation where they initially fight over it. However, as they start to understand the true nature of the artifact and the real threat behind it (maybe an ancient evil that awakens on Halloween), they join forces to deal with it and prevent disaster.
One popular type is adventure - based fanfiction. For example, there could be a story where Knuckles and Rouge team up to find a lost ancient relic. They have to overcome various obstacles and enemies in their path.
The potential for growth in their relationship. Knuckles is a bit of a stoic character, and Rouge is full of charm and guile. In fanfiction, writers can explore how Knuckles learns to open up and show his softer side because of Rouge. And Rouge can find a sense of loyalty and true connection with Knuckles that she may not have had before. Their relationship can be a journey of self - discovery for both of them, which is really appealing in fanfiction.
A sense of isolation is sometimes a theme. Rouge may feel isolated as a vampire, different from her previous self and those around her. And Knuckles may also feel a sense of isolation in trying to deal with Rouge's situation on his own, without fully understanding the vampire world. This creates a complex emotional landscape in the fanfictions.
A common theme is the clash of their personalities. Rouge is sly and often self - interested while Knuckles is noble and duty - bound. Their relationship development is also a big theme, whether it's friendship or something more romantic.
One common theme could be the adjustment to the new situation. Both Rouge and Knuckles would need to adapt to the idea of becoming parents. Another theme might be the protection of the unborn child. Since they are often in a world full of action and danger in their original stories, this would be an important aspect.
One common theme could be conflict. Given that Knuckles is hurting Rouge, there might be a story of betrayal or misunderstanding between them.
