One possible plot could be that Pikachu, as a girl, goes on an adventure to find a special type of berry that is said to have magical powers. Along the way, she meets other Pokémon who initially don't accept her because she's different. But through her kindness and determination, she wins them over and they all help her find the berry in the end.
It could change the way Pokémon interact with each other. For example, male Pokémon might show more chivalrous behavior towards a girl Pikachu. Also, it might inspire other fanfiction writers to create more stories with gender - bent Pokémon, leading to a more diverse range of stories in the Pokémon fanfiction community.
One possible plot could be that Pikachu, after being exposed to a strange form of energy in the Pokémon world, transforms into a girl. She then has to deal with the confusion of her new form while still having her Pikachu memories. She might struggle to fit into the Pokémon society in this new body, but also discovers new abilities or a deeper connection to certain types of Pokémon that she didn't have before.
One possible reason could be that Pikachu is separated from Ash. In many fanfictions, their bond is so strong that being apart would be extremely distressing for Pikachu, leading it to cry.
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, Naruto's chakra-based powers and Pikachu's electric powers can combine in some fanfictions. For instance, Naruto could use his Rasengan and Pikachu could add its electric charge to it, creating a super - charged attack that is more powerful than either of their individual attacks.
Another way is to explore her relationships. If she's a girl, she might have a different dynamic with Ash (assuming it's set in the Pokémon anime universe). Maybe she's more of a confidante to Ash, listening to his problems and offering her own cute, Pokémon - perspective advice. Also, she could interact differently with male Pokémon, perhaps showing a bit of shyness or coyness at times.
Definitely. The idea of Ash and Pikachu's friendship is very popular in fanfiction. Their relationship is iconic. Fanfictions could tell stories of how they first met and how that initial connection grew into an unbreakable bond. It could also include side characters from the Pokémon world who notice and are inspired by their friendship, like Misty or Brock seeing how Ash and Pikachu always have each other's backs.
Brock could be a great addition. He could provide some comic relief and also be the voice of reason. For example, when Ash and Pikachu get into some crazy situations, Brock could be the one to offer practical solutions.
