It could be a rival trainer. Rival trainers are often very competitive in the Pokémon world. Maybe this rival is jealous of Ash and May's progress and decides to betray them to slow them down. They might spread false rumors about Ash and May, causing other trainers to be distrustful of them.
Sure, in a fanfic, the author has the creative freedom to envision such a situation. Maybe May could accidentally or intentionally cause harm to Ash due to various plot twists and conflicts.
May would probably look up to Ash even more. Since Ash has a lot of Pokemon - related knowledge and experience, as her'mom', he could pass on some unique skills and wisdom. Their relationship might also have some emotional depth added to it, like when May is feeling down, Ash would be there to comfort her like a mother would, which is different from their usual trainer - to - trainer relationship.
One way is to focus on their friendship. For example, write about how they support each other during Pokémon battles. They can exchange tips on training Pokémon or strategies for winning competitions.
Definitely not. May Parker is a beloved character and pornographic comics featuring her would be highly inappropriate and against ethical and legal standards.
May could be considered a good match for Ash in fanfiction. She has a tomboyish charm and her own set of Pokémon skills. Their journey together in the anime provides a lot of material for fanfiction writers. They've had moments of competition and cooperation, which can be explored more deeply in fanfiction. However, Dawn also has her own appeal. She's elegant and has a passion for contests, and her relationship with Ash can add a different flavor to the fanfiction, like a more refined kind of partnership.
No. Writing erotic fanfic involving characters is inappropriate as it goes against the original intention of the characters and can be considered unethical and violate various community standards.
