One common theme is the clash of different worlds. For example, when Stiles crosses into a different universe like the Vampire Diaries' world, his normal life from the Teen Wolf universe clashes with the supernatural politics and rules of the new world.
Friendship and alliance building is often seen. Stiles is a character who can form bonds quickly. In a crossover fanfiction with the Percy Jackson series, he might team up with the demigods. Through these alliances, he not only helps the other characters but also discovers new aspects of himself while facing common enemies.
Character growth is also a big theme. Stiles often has to adapt and learn new skills or ways of thinking in these crossovers. In a crossover with the DC universe, he might have to become more physically capable or learn to deal with the moral gray areas that superheroes face, which helps him grow as a character.
One common theme is friendship. Often, the female character starts as a friend to Stiles and their relationship evolves from there. Another theme is mystery, as they might solve some supernatural mystery together. For example, in many fanfics, they team up to figure out the latest werewolf or banshee problem in Beacon Hills.
A prevalent theme is Stiles' self - doubt and how it gets exacerbated when he's hurt. He might question his own worth, especially if he thinks his being hurt is putting his friends in danger. Fanfictions often show his internal struggle as he tries to come to terms with his situation and regain his confidence. Sometimes, his hurt can also be a catalyst for character growth, where he learns to be more self - reliant or better at communicating his feelings.
One common theme is self - discovery. Stiles often has to figure out his true feelings and identity in these fanfics. Another theme is acceptance, both from himself and from those around him.
In female Stiles Stilinski fanfic, a prevalent theme is empowerment. The female version of Stiles often has to prove herself in a male - dominated supernatural world. Adaptability is another theme, as she has to adapt to new situations and powers. And of course, loyalty. Her loyalty to her friends and the pack is always a central theme, just like in the original Teen Wolf story. These themes help to shape the character and make the fanfics engaging and relatable.
The theme of growth and change is also prevalent. The pregnancy forces both Stiles and the OC to grow up and take on more responsibilities. They have to adapt to their new situation, which can be a source of character development. For example, Stiles might become more serious and focused on building a stable future for his family, while the OC might discover new strengths within herself as she prepares to become a mother.
One common theme is the 'fish out of water' scenario. Since Stiles is from a world with werewolves and magic, and Steve is from a more 'normal' superhero world at first glance, their interactions can create interesting situations where they learn about each other's worlds.
One common trope is the 'unlikely alliance'. Given Peter's often - untrustworthy nature and Stiles' wariness, stories often start with them being forced to work together. Another is the 'protective Peter' trope, where Peter feels a need to protect Stiles for some reason. It could be because he sees Stiles' value to the pack or something more personal.
A plot could involve Stiles' real family crossing over into a world where they are all superheroes. Stiles has to adjust to having powers and his family has to deal with the new responsibilities. There could be a villain that targets Stiles' family specifically because of their newfound powers, and they have to work together to defeat the bad guy.
There's 'Stiles and the Winchester Brothers'. This fanfiction crosses over Stiles with the Supernatural world. Stiles' character really stands out as he tries to navigate the world of hunting and the Winchester family's dynamic. It has some really interesting plot twists and great character interactions. For example, his banter with Dean and Sam is both humorous and engaging.
Lydia Martin would also be a good character to include. She's smart and powerful, and her relationship with Stiles could be further explored in the context of the crossover. Her banshee abilities might come in handy when dealing with any new threats in the crossover world.
