In fanfiction where Ash turns into a girl, it could lead to some interesting plot twists. Maybe his relationships with his Pokémon would change in unique ways. For example, some Pokémon might be more protective of him now that he's a girl. Also, his interactions with other trainers, like Misty and Brock, would be different. They might treat him with more chivalry or have different emotional responses to his new form.
A lot could change. His fashion sense might be completely different. Instead of his usual cap and jacket, he could be wearing more feminine outfits. His Pokémon might need to get used to this new look too. Pikachu might be a bit confused at first but then adapt. Also, Ash's rivals might not take him as seriously at first when he's a girl, but he could prove them wrong with his skills.
One possible plot could be that a spell or a magical artifact causes Ash to turn into a girl. Ericka might be involved in the discovery of this transformation. Ash then has to deal with the new physical form while still trying to pursue his Pokemon journey. His Pokemon might initially be confused but still recognize him. And he could face different challenges and reactions from his friends and rivals as a girl.
His best friend Pikachu might be a bit confused at first but would quickly adapt as it still senses Ash's essence. Brock would probably be very surprised and might offer some comical comments or advice on how to handle the new situation. Misty could be a mix of shocked and intrigued. She might be a bit jealous of Ash's new female appearance at first, but then would support him as they are friends.
I haven't come across a fanfiction where Ash turns into May's mom myself. But given the creativity of fanfiction writers, it's entirely possible that someone has written such a story. It could potentially be part of a more complex plot within the Pokémon fanfiction universe, perhaps involving some sort of magic or strange experiment gone wrong that causes this transformation.
Well, in these fanfictions, a frequent theme is identity. Ash has to grapple with his new identity as Arceus. He's no longer just a regular Pokémon trainer. Also, the theme of sacrifice is common. There's usually something that led to his transformation, which might have involved sacrificing something he held dear. Additionally, many of these fanfictions touch on the theme of change. His transformation into Arceus brings about changes in his relationships with his Pokémon friends and other trainers in the world.
