Family and relationship themes are often present. For example, how the character's family and friends react to the pregnancy in the context of a crossover. Maybe in a crossover with a magical world, there could be magical elements related to the pregnancy like special powers for the unborn child.
Another theme could be the cultural clash if the crossover is with a world from a different cultural background. The Ranma 1/2 characters may have different values and beliefs about pregnancy, and when combined with the other world's ideas, it can create interesting storylines. Also, the growth and development of the pregnant character both physically and emotionally can be a major theme, as they navigate through this new phase of life in a crossover setting.
One common theme could be the challenges of the female Ranma dealing with pregnancy in a crossover universe. Maybe she has to adapt to different cultures or magical elements from the crossover.
One common theme could be Hermione's strength and resilience in a difficult situation. Despite being imprisoned, she might show her intelligence and determination, especially when dealing with the challenges of being pregnant.
One common theme could be friendship. When characters from Harry Potter cross over into another universe, they often form new friendships. For example, if they cross over into a superhero universe, they might team up with the heroes there and learn about different kinds of heroism. Another theme is the exploration of different magic systems. If it's a crossover with a different fantasy world, comparing and contrasting the magic in Harry Potter with that of the other world can be really fascinating.
A third theme could be self - discovery. 'Futa' characters in Naruto fanfics may embark on a journey of self - discovery, learning about their own strengths, weaknesses, and place in the ninja world. This could involve exploring their unique identity within the context of the Naruto universe and how they can contribute to their village or group.
Friendship is a big theme. Team RWBY's bond is central in the RWBY series, and in fanfics, this can be further explored. They might face challenges that test their friendship, like disagreements over battle strategies or misunderstandings. But through communication and mutual understanding, their friendship becomes stronger. This is a great theme that can be found in many RWBY fanfics, whether they are 'naughty' or not in an inappropriate sense.
Another theme could be the shared experiences that bring them closer. Despite their rivalry, they may have gone through similar hardships or challenges. In the fanfic, this could be explored as a way to bridge the gap between them. They might start to see each other in a new light and form a deeper connection.
Perhaps in some comical anime fanfic, there could be themes where characters accidentally get wet in a humorous way. This could lead to funny situations like their clothes getting all soggy and them having to deal with the embarrassment, which is a much more light - hearted and family - friendly take on the idea of 'wetting' compared to what might be in inappropriate fanfic.
Another theme could be the relationships Naruto forms in this 'playboy' - like scenario. It could be about how he manages multiple friendships or potential romantic interests. He might be portrayed as a bit of a heartbreaker or someone who is just exploring different relationships without really settling down right away.
One common theme could be Katara's journey of self - discovery. As she grows in her bending abilities and her understanding of the world around her, fanfics can focus on how she matures. Additionally, her cultural identity as a Water Tribe member can be a theme, exploring how she upholds and passes on the traditions of her tribe while also adapting to the changing world of the Avatar.
Friendship is also a big theme. Since both Ranma and Naruto value friendship highly in their original series, in the crossovers, they usually form a strong bond. They learn from each other's strengths and support each other in facing various challenges.
