What are some popular Pokémon fanfiction themes other than something like Ash Ketchum getting Diantha pregnant?

I'm not sure if there is such a specific fanfiction. Fanfiction can cover a wide range of wild and creative ideas, but this one might be quite rare or not in the mainstream. It also might not be in line with the original spirit of the Pokémon series in some ways.

One great theme is Ash's adventures in new and unexplored regions. He could discover rare Pokémon, face new challenges in battles, and form unique bonds with local trainers. Another theme could be the backstories of Pokémon themselves. For example, how a particular Pokémon came to be in the wild or how it was rescued from a difficult situation.

Well, there are themes like Ash and his Pokémon's encounter with legendary Pokémon. This could lead to all kinds of adventures, like having to solve a mystery that the legendary Pokémon is involved in. Another theme is Pokémon rescue. Ash and his team could be on a mission to save Pokémon from poachers or natural disasters. And of course, there are fanfictions about Ash building a Pokémon sanctuary where all kinds of Pokémon can live in harmony.

Well, a common theme is the exploration of different regions. In these fanfictions, Ash and Diantha often visit new and exotic places in the Pokemon universe. Also, the theme of self - discovery is there. As they interact, they learn more about themselves. Romance is a big theme too. It's about how their relationship evolves from just knowing each other to falling in love, with cute and sometimes awkward moments in between.

One popular theme is adventure. Fans love to read about Ash, Cynthia and Diantha going on exciting journeys, exploring new regions and encountering rare Pokémon. Another common theme is competition. Since they are all strong trainers, stories about them competing against each other or teaming up to compete against others are quite popular. For example, in many fanfictions, they enter a big Pokémon tournament together.

Another type of fanfiction could be a time - travel one, where Ash from his present meets a younger Diantha. They then start a journey that changes the course of both their futures, with lots of action and new Pokémon encounters along the way.

One popular Ash Diantha fanfiction could be about their adventures in a new region together. Maybe they team up to face a powerful and mysterious Pokémon. It often involves a lot of character development for both Ash and Diantha, exploring their relationship in different ways.

One popular theme is the growth of Ash's relationships with the different characters in his harem. It often shows how they support him in his Pokemon journey. Another theme could be the unique dynamics between Ash and each member of the harem, like how they interact during battles or in different regions.

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 common theme is adventure. Since both are involved in the Pokémon world, they often embark on exciting journeys together in fanfictions. Another theme is friendship. Writers like to explore how they become friends and support each other.
