I'm not aware of any one particular fanfic that is extremely popular in this very specific category. Fanfic popularity can vary a great deal among different groups of readers.
Overcoming challenges together is a theme as well. Just like in the original series where Ash faces various Pokemon - related challenges, in these fanfics, he and his love interest face challenges related to their relationship, such as dealing with other people's opinions or finding time for each other while on their respective Pokemon journeys.
A possible storyline could be that Ash has a gay friend who is struggling with coming out to his family. Ash, being the kind - hearted person he is, encourages his friend and helps him find the courage to be true to himself. Along the way, they also have Pokémon battles and adventures together.
One story could be about Ash Ketchum forming a special bond with a male trainer during his journey. They might team up for a tough Pokémon battle and support each other in a way that shows deep friendship and camaraderie. Another could be Ash helping a gay Pokémon trainer overcome some discrimination in the Pokémon world, using his own influence to make the place more inclusive.
I'm not sure specifically which ones are the 'good' ones as it depends on personal taste. However, you can try searching on fanfic platforms like Archive of Our Own. They might have a variety of fanfics related to this theme.
One popular Ash Ketchum gay fanfic might be those that explore his relationship with another male character in a new and interesting way. For example, some might focus on his bond with Gary Oak in a more than just friendly context. However, it's important to note that fanfics can vary greatly in quality and content.
Another one is 'Love in the Pokemon League'. In this fanfic, Ash meets a fellow trainer during a league competition and they gradually develop feelings for each other. It's a heartwarming story that shows how love can develop even in the midst of intense battles.
Some fans are attracted to Ash Ketchum gay fanfics because they enjoy exploring uncharted territories in the Pokémon universe. The original series mainly focuses on Ash's journey as a Pokémon trainer, but these fanfics shift the focus to his personal relationships. By making Ash gay in these stories, it opens up possibilities for different types of character development. It can also lead to exploring different cultural and social aspects within the fictional world. Additionally, it can be a form of self - expression for fans who want to create or consume content that goes against the norm of the mainstream Pokémon narrative.
Maybe a new, mysterious villain who has a grudge against Ash or wants to use his skills for their own evil purposes. This villain might be from a far - off region and has special powers that allow them to hypnotize people. They see Ash as a useful tool to carry out their plans in the Pokémon world.
