A fanfic could be centered around Ash exploring a new region where Mimikyu is said to be very common. Ash is eager to add a new and different Pokemon to his team. He meets a local trainer who tells him all about Mimikyu's habits. Ash follows the trainer's advice and goes to a particular meadow where Mimikyu likes to play. He waits patiently until he sees a Mimikyu. Ash then uses his best Pokeball and with a little bit of luck, catches Mimikyu. Once caught, he discovers that Mimikyu has some hidden powers that he's excited to explore and train with.
One common theme is Mimikyu's loneliness. Since it's a Pokemon that disguises itself because it's self - conscious about its appearance, many fanfics focus on its isolation and the longing for connection.
A common theme is friendship. Pikachu and Buneary are often shown as good friends, relying on each other. Another theme could be adventure, as they explore the Pokemon world together.
A very interesting fanfic is 'Mimikyu's Secret World'. This fanfic explores the world from Mimikyu's perspective. It shows how Mimikyu sees other Pokemon and humans. It's a beautifully written piece that gives a lot of depth to the character of Mimikyu.
One popular 'pokemon pikachu x buneary fanfic' could be 'The Adventures of Pikachu and Buneary'. It often shows their unique friendship and how they team up in the Pokemon world. Another one might be 'Pikachu and Buneary: A Special Bond' which delves into their relationship development.
Their relationship can be developed through shared experiences. For example, when they encounter a difficult Pokémon battle together, Pikachu can protect Lillie, and Lillie can in turn use her skills to support Pikachu. This mutual reliance will strengthen their bond.
A plot could revolve around Pikachu getting sick and Lillie using her knowledge of Pokémon care to nurse it back to health. During this time, they develop a deep friendship. Then, they notice some strange behavior in other Pokémon around them. Together, they start to investigate and find out that there is a pollution source affecting the Pokémon. Lillie and Pikachu then try to find a way to clean up the pollution and restore the health of the Pokémon in the area. This would show their caring and adventurous sides.
In fanfics, Pikachu's Force Lightning can be depicted in various ways. Some might show it as an extremely powerful attack that can even take down much larger and stronger Pokemon. It could be a result of Pikachu reaching a new level of power or being in a special state of rage or determination.
I really like the fanfic 'Pikachu and Buneary's Bond'. In this story, Pikachu first meets Buneary when she is injured. He takes it upon himself to help her get better. As they spend time together, they form a deep bond that goes beyond just friendship. It's a heartwarming story that shows how Pokemon from different species can connect on an emotional level.
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.
