Ash is that energetic trainer we all know from Pokemon, always eager to take on new challenges and befriend more Pokemon. Astrid in Pokemon fanfiction can be seen as a fresh addition to Ash's world. She may be designed to add new dynamics to the story. Maybe she has a different approach to Pokemon training compared to Ash, like focusing more on Pokemon's natural instincts rather than just battle strategies. And she and Ash could start off not getting along but then gradually become good friends as they share experiences in the Pokemon world.
One interesting storyline could be Ash and Astrid teaming up to compete in a special Pokemon tournament. They might face tough opponents and have to come up with unique strategies using their Pokemon's skills. Another could be a story where they explore a mysterious new region together, discovering new Pokemon species along the way. And they could also be involved in a plot where they have to save a group of endangered Pokemon from an evil organization.
You can develop Ash by highlighting his bond with his Pikachu in new ways. Maybe Pikachu gets sick and Ash has to find a rare cure, and Astrid helps him. This shows his caring side. For Astrid, give her a signature Pokemon that has a special bond with her. Describe how she trains it and how it reflects her character. You can also include how she and Ash learn from each other's training methods, which would develop both characters.
A more complex plot could be set in a world where there is a threat to all Pokemon. Ash and Astrid, along with their Pokemon friends, have to gather a set of ancient artifacts to save the Pokemon world. Along the journey, they have to overcome their own personal doubts and differences to succeed.
One common theme is friendship. Astrid often forms strong bonds with her Pokemon and other trainers. Another theme is adventure, as she travels through different areas in the Pokemon world. Growth is also a theme, as Astrid develops as a trainer throughout the story.
Pikachu is a very likely candidate. It's Ash's most iconic Pokemon and has a deep bond with him. Whenever Ash is in trouble, Pikachu often steps up to protect him.
Ash could be a Pokémon trainer with a different starting point in this fanfiction. Born in 1987, by 1997 he might have already made a name for himself in local Pokémon battles. He could have a team of Pokémon that he rescued from difficult situations, like a Charmander that was abandoned by its trainer. His story could revolve around giving these Pokémon a second chance and proving that Pokémon don't need to be 'perfect' to be strong.
The impact of Ash's loss in the fanfiction could extend beyond just himself. His Pokémon might also feel demoralized. However, this could also be an opportunity for them to grow stronger together. Ash could start training more intensively, seek new training methods, or even try to catch new Pokémon to strengthen his team.
One popular type of Pokemon Ash and Pikachu fanfiction might be adventure - based. For example, Ash and Pikachu could embark on a journey to a new and mysterious region filled with undiscovered Pokemon species. They might face challenges like difficult terrains and powerful, previously - unseen Pokemon. In this fanfiction, Pikachu's electric powers could be enhanced in some unique way, and Ash would have to strategize differently to overcome the obstacles.
Well, in certain fanfictions, Ash's inexperience in handling different Pokémon species can make him seem like a bad trainer. He may not be aware of the specific training methods required for some Pokémon. For instance, he might treat a very delicate and rare Pokémon the same way he treats his more common ones, which could lead to the Pokémon not reaching its full potential.
