Well, a big theme is cultural clashes. When Bender crosses over into a different fictional world, there are often differences in values and norms that create conflict and humor. Also, redemption arcs can be a theme. Maybe Bender has done something bad in the crossover world and has to make up for it. And the theme of exploration is there too, as he explores new places and meets new characters.
One popular theme is alternate universes. For example, Bender could be in a universe where he's a detective, which creates really interesting storylines. Another theme is friendship crossovers, like Bender teaming up with characters from other shows or movies to go on an adventure. There's also the theme of technology gone wrong in different settings. It adds a lot of drama and action to the fanfiction.
One popular theme is exploring how Ash's relationships change. For example, his friendships with Brock and Misty might take on a different dynamic as a female. Another theme could be the way she approaches Pokémon battles. Maybe she'd use more strategy based on her new perspective. Also, the story could focus on how the Pokémon world reacts to this gender - bended Ash. Do they notice a difference in her leadership style or the way she interacts with them? It can be really interesting to see how the fanfiction writers play with these ideas.
One example could be a crossover between 'Harry Potter' and 'Supernatural' where Hermione is gender - bent into a male character in a story that involves hunting demons in Hogwarts. Another might be a 'Star Trek' and 'Buffy the Vampire Slayer' crossover with Captain Kirk being a female in a world full of vampires and space travel combined. There's also often 'Marvel' and 'DC' crossovers in this genre where, for example, Superman could be gender - bent and interact with the female - dominated world of the X - Men.
One popular theme is Sabrina crossing over with other magical universes. For example, a crossover with Harry Potter could involve Sabrina attending Hogwarts and interacting with the students there. Another theme is a crossover with fairy - tale characters. Sabrina might meet Cinderella or Snow White and get involved in their stories. Also, a modern - day crossover where Sabrina enters the world of a popular TV show like 'Stranger Things' can be really interesting, with her magic causing chaos in the Upside - Down.
A common theme is the exploration of their relationship in different scenarios. In some fanfictions, they might be in a post - apocalyptic world where they have to rely on each other even more than in the original story. This intensifies their bond and shows different aspects of their love and loyalty. There are also fanfictions that focus on the 'what ifs'. What if Eren had made different choices? How would that affect his relationship with Mikasa? This kind of theme allows for a lot of creativity and speculation.
One popular theme is Naruto characters crossing over into other anime worlds like One Piece or Bleach. For example, Naruto might end up on the Grand Line in One Piece and have to deal with pirates and Devil Fruits. Another theme could be Naruto characters in a modern - day setting, like going to a high school in the real world. It's also common to see crossovers with superhero universes, where Naruto characters gain superpowers similar to those of Marvel or DC heroes.
One popular theme is adventure. Haku might be combined with characters from other stories and embark on epic quests. For example, a crossover with a fantasy adventure series could see Haku exploring new magical realms.
One popular theme is characters from different Disney movies teaming up for an adventure. For example, characters from 'Frozen' and 'Moana' might join forces to save their kingdoms from a common threat. Another theme could be romantic crossovers, like a love story between a character from 'Beauty and the Beast' and one from 'Aladdin'.
Some popular themes include adaptation. The soldier has to quickly adapt to the new rules, cultures, and technologies of the crossed - over world. Another is the clash of ideologies. A military - minded soldier might have different views compared to the characters in a more peaceful or magically - based world. And there's the theme of discovery. The soldier discovers new things about themselves, like hidden strengths or weaknesses, as they face the challenges of the crossover world.
One popular theme is the clash of different cultural elements from the various source materials in the crossover. For example, if it's a harem crossover between a Japanese anime and a Western fantasy series, there might be a contrast between the Japanese concepts of honor and the Western ideas of chivalry. Another theme could be the power dynamics within the harem. Different characters from different universes may have different levels of power, and how they interact and compete or cooperate in the harem setting can create interesting storylines. Also, the exploration of love in a multi - character context is a big theme. Each member of the harem may have a unique relationship with the main character, and the story could focus on how these relationships develop and evolve over time.
Friendship and alliance themes can also be found. Characters from different fandoms might form unexpected alliances in order to combat Slender Man. In some cases, they might learn about each other's strengths and weaknesses during this process. Additionally, the theme of discovery is important. As characters enter the world of Slender Man in the crossover, they discover new things about themselves and the nature of the horror they are facing.
