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.
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.
One idea could be a story where Knuckles and Rouge have to team up to protect a hidden ancient relic from a new villain in the Sonic universe. They start off distrusting each other as usual, but as they face challenges, they gradually learn to work together better.
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.
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.
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.
Many of these fanfictions play with the idea of them being on opposite sides but finding common ground. They might start out as rivals or even enemies but gradually develop feelings for each other. The best ones also incorporate elements from the Sonic universe, like references to other characters or locations. For instance, they could meet in a hidden temple on Angel Island, which adds an extra layer of authenticity to the story. Another characteristic is the development of their relationship. It's not just about them falling in love immediately. It's a slow - burn process where they learn to trust and respect each other.
There could be a theme of sacrifice as well. They might have to sacrifice some of their previous ways of life, like their solo adventures or their more carefree attitudes. And also, how they come to terms with the fact that their lives are now centered around this new family they are creating.
