Character development is key. A good fanfiction should show how Ash and Leaf grow as individuals and as friends. For example, they might start as rivals and gradually become reliable partners.
One common theme is friendship. Ash and Leaf are often depicted as very good friends who support each other through thick and thin. For example, in many fanfictions, Leaf will help Ash when he's facing a tough Pokémon battle.
In these fanfictions, Gary Oak can be a significant supporting character. He might be a rival to Ash in different ways, like in Pokemon battles or in winning Leaf's attention. Professor Oak is also important as he provides knowledge and resources for Ash and Leaf's Pokemon - related activities. There could also be some original characters created specifically for the fanfiction, like a young trainer who looks up to Ash and helps him and Leaf on their journey.
One common plotline is Ash and Leaf going on adventures together with a group of Pokemon that are unique to their story. Another could be Ash having to protect Leaf from various threats in the Pokemon world while their relationship deepens. And sometimes, they might encounter rare and powerful Pokemon that change the course of their journey.
Perhaps Leaf betrays Ash because she becomes jealous of his friendship with Pikachu. She might feel like Pikachu gets all of Ash's attention and decides to side with a group that wants to separate them. This could lead to Ash having to fight not only to save Pikachu but also to win Leaf back.
It could be a new and powerful trainer who has a vendetta against Ash. This trainer might see Ash as a threat to their own rise to the top in the Pokemon world. They could manipulate Leaf into betraying Ash to further their own goals.
Ash could also have Charizard. It's a powerful and well - loved Pokemon of his. It could provide a lot of firepower in battles. For Gray, a Glaceon would be great. Glaceon's ice - type moves could complement Gray's more strategic style. It could freeze opponents and give Gray time to plan his next move.
