There might be some fanfics that are relatively well - known within the subset of fans who are interested in this kind of story. However, in the broader scope of all Pokémon fanfics, it's hard to single out one as 'popular'. Fanfic popularity often depends on how well it's promoted within its specific community, the uniqueness of the story, and the writing quality. Since this is a rather specific and niche topic, it may not have a fanfic that has broken out into mainstream popularity among all Pokémon fans.
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.
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.
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.
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.
It's not one of the most mainstream genres in fanfiction. However, within certain niche communities that are interested in gay - themed stories with a particular focus on light - hearted and somewhat unique interactions like tickling, it can be popular.
One idea could be that Ash sacrifices himself to save his Pokémon during a really intense battle against an extremely powerful and evil Pokémon. Another might be related to a disease spreading in the Pokémon world that Ash contracts and unfortunately doesn't survive. Maybe in a fanfic, he gets caught in a natural disaster in a far - off region while on a journey and perishes.
I'm not aware of any specific 'Ash Ketchum impregnation fanfic' stories as such content often goes against the family - friendly nature of the Pokémon franchise. Fanfics usually focus on adventures, friendships and Pokémon battles in the Pokémon world.
One popular 'Ash Ketchum and Serena fanfic' story could be about their adventures in a new region that wasn't shown in the original series. Maybe they discover a new type of Pokémon together and their relationship deepens as they face challenges in taming it.
In a fanfic, Ash could be turned into a vampire by an ancient, powerful Pokemon with vampiric abilities. This would completely change his relationship with his other Pokemon. Some might be scared of him, while others would stay by his side. He would then have to learn to control his vampire powers and instincts in order to continue his journey. For example, he'd need to figure out how to be in the sunlight without getting burned as he travels from place to place.
