One common theme is friendship. Since they are two different Pokémon, their journey to becoming friends is often explored. For example, they might start off not understanding each other but then learn to appreciate each other's strengths.
The contrast between their types makes it interesting. Pikachu is an Electric - type and Snivy is a Grass - type. Their interactions can lead to unique storylines, like how they deal with different terrains. Electric - type Pokémon are often associated with speed and energy, while Grass - types are more about calmness and growth. When combined in a story, it can create a great dynamic.
The setting is also important. It could be in a bustling Pokémon city, a quiet rural area, or a dangerous wilderness. The setting affects the kind of challenges they face. For instance, in a city, they might have to deal with human - Pokémon relations, while in the wilderness, it could be about surviving against wild Pokémon.
One great snivy x pikachu fanfiction is 'The Unlikely Bond' which focuses on how Snivy and Pikachu, despite their different natures, form a strong friendship. It has some really cute interactions between them as they face challenges in the Pokémon world together.
Their interaction can be portrayed as a classic case of an energetic and friendly Pikachu trying to get the usually calm and collected Snivy to loosen up. For example, Pikachu could be constantly jumping around Snivy, trying to get it to play, while Snivy is initially reluctant but gradually warms up.
One interesting plot could be Pikachu and Snivy teaming up to explore a mysterious new region in the Pokemon world. They encounter new Pokemon species and have to work together to overcome various obstacles like difficult terrains and powerful wild Pokemon.
One possible plot could be that Pikachu and Snivy get separated from their trainers during a storm. They then have to rely on each other to find their way back. Along the way, they learn about each other's strengths and weaknesses and form a strong bond.
I'm sorry, but 'lemon' in fanfiction often refers to adult - themed content. I can't recommend such works. However, you can look for general Pikachu and Snivy friendship or adventure - themed fanfictions on platforms like FanFiction.net.
There could be a fanfiction where Pikachu and Snivy participate in a Pokémon tournament together. They train hard and develop new strategies. Snivy might learn some new moves by observing Pikachu's fighting style, and Pikachu could gain better control over his electric attacks with Snivy's advice. Their bond grows stronger as they progress through the tournament, facing tough opponents and making new friends along the way.
In a 'ash and pikachu snivy betrayed' fanfiction, the betrayal could stem from a misunderstanding. Maybe Snivy overhears Ash making a plan that it misinterprets as something harmful to the Pokémon world. As a result, Snivy feels it has no choice but to betray Ash and Pikachu to protect what it believes in. It could then side with a group of anti - human Pokémon who are also misinformed about Ash's intentions.
