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.
Friendship is a very common theme. Pikachu and Ash have a special bond that is often explored in these fanfics. Their loyalty to each other and how they support one another through different situations.
One common theme is friendship. Ash and Pikachu have a very strong bond, and this is often explored in fanfiction. Another theme could be adventure. They are always on a journey in the Pokemon world, so many stories are about their new adventures.
The main appeal is the deep bond between Ash and Pikachu. In fanfics, this bond can be explored in different ways. For example, in some, they might face a great danger together that tests their relationship.
Friendship is a very common theme. The unbreakable bond between Ash and Pikachu is often explored. Another theme is adventure, as they are always going on quests in the Pokemon world. Trust is also a big theme, as they rely on each other completely.
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.
Well, if such a fanfic existed, it would be very wrong. Ash and Pikachu have a pure friendship - like relationship in the Pokémon world. A 'lemon' fanfic usually implies sexual or inappropriate content, which has no place in the Pokémon universe.
For Ash, you can develop his character by showing how his views on Pikachu change or expand because of the female fan. Maybe he starts to see new aspects of Pikachu that he hadn't noticed before. For the female Pikachu fan, you could give her a backstory of how she became such a big fan. For example, she had a sick Pikachu as a child that was healed by a mysterious Pokémon trainer, and that's what sparked her love.
One possible storyline could be that Ash and a female Pikachu fan meet at a Pokémon convention. They start talking about their love for Pikachu and then embark on an adventure together to find a rare Pikachu - colored stone that is said to have special powers. Along the way, they face challenges and grow closer as friends, with a hint of potential romance in the air.
One possible plot could be that the female Pikachu is a lost Pokémon. Ash finds her and decides to help her find her way back home. Along the way, they face various obstacles and make new friends. Another plot could be that the female Pikachu has a prophecy related to Ash. She is destined to be by his side during a great battle against an evil force. So they team up and train hard for this upcoming battle.
