Obviously, the main characters are usually Pikachu. But sometimes, there could be other Pokémon that play important supporting roles. For instance, a Pichu could be a sidekick or a younger Pokémon that the Pikachus are protecting.
One interesting plot could be two Pikachus from different regions meeting and learning about each other's unique electric attacks. For example, one Pikachu might know a special move that the other has never seen before. They could then teach each other and become stronger together.
Well, it depends on the popularity of this particular pairing within the fan community. There might be some fanfics, but it could also be a relatively niche pairing. You could also try reaching out to Pokemon fan groups on social media platforms to ask if anyone knows of such fanfics.
I'm not sure if there is an exact 'ash x pikachu lemon fanfic' available. Fanfics can be quite diverse, but this combination seems rather strange as Pikachu is a Pokémon. Most Pokémon fanfics focus on more common relationships within the Pokémon universe, like trainer - Pokémon partnerships in a non - strange way.
Perhaps in some fanfics, Pikachu and Sparky could be from different regions and they meet by chance. Their different backgrounds and abilities could lead to an interesting story as they learn from each other and overcome difficulties. For example, Sparky might be from a region with different types of electric - type Pokémon techniques that Pikachu has never seen before, and they could exchange knowledge. This could also lead to a deeper emotional connection between them as they grow to respect and care for one another.
The main characters are Ashchu and Pikachu. In the fanfic, Ashchu might be a unique character with his own set of skills and personality traits. Pikachu, on the other hand, is the iconic Pokémon we all know. Their relationship forms the core of the fanfic, whether it's a story of friendship, adventure, or discovery.
One common theme is growth. Since Raichu is an evolved form of Pikachu, fanfics might explore Pikachu's journey towards evolving and how Raichu plays a role in that.
One common theme is friendship. Since Pikachu and Buneary are both Pokemon, they can form a strong bond in the fanfics, much like how Pokemon form bonds with their trainers in the actual games and anime. They might help each other out in difficult situations.
I know that Archive of Our Own (AO3) also has a wide variety of fanfics. It has a great tagging system. So you can search for Pikachu and Buneary tags, and then sort through the results to find ones that seem appealing to you. Some of the fanfics might have unique storylines, like Pikachu and Buneary going on an adventure together in a different region of the Pokemon world.
