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.
There would be a shift in power dynamics too. Ash as the'mom' would have more authority over May. He would be able to make decisions for her in certain situations, like which Pokemon training camps she should attend. However, at the same time, he would also be nurturing her independence, teaching her how to make good decisions on her own as she grows up in the world of Pokemon.
Ash and May's relationship would deepen in many ways. With a baby on the way, they would start seeing each other in a new light. Ash, who was always adventurous, would now also think about the safety and well - being of his family. May would find Ash more reliable and loving. They would have to work together to create a stable home environment for the baby. For example, they might argue a bit about which Pokémon should be around the baby when it's born, but through these discussions, their relationship would grow stronger.
It could be that in an alternate universe, Ash is born as a much older person and becomes May's mother in a more traditional sense. He might have different Pokemon knowledge and experiences which he passes on to May. He could be strict about some things like safety during Pokemon battles and lenient about others, like letting May choose her own first Pokemon even if it's not the most common or powerful choice.
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.
Sure. There are fanfictions where they are just good friends and they help each other out in Pokemon battles or in exploring new regions. Their relationship can be shown as a strong bond based on mutual respect and support without any romantic or inappropriate content.
Their relationship would become more mature. They would have to rely on each other more than ever. With a baby, they'd have to share responsibilities, which could lead to a deeper understanding and respect for each other.
Their relationship would likely become more domestic. They would have to rely on each other more for the care of the baby. There would be more shared responsibilities, which could strengthen their bond.
His relationship could change in terms of training. Ash might start to incorporate some of Giovanni's more strategic training methods (assuming he learns about them). However, his Pokémon might be resistant at first, as they are used to Ash's traditional and more friendly training style. But over time, they could adapt and become even stronger. Also, Ash's Pokémon might have to deal with new rivals associated with Giovanni, which would test their loyalty and determination to stay with Ash.
If there was a fanfiction where Ash becomes May's mom, it could be a story full of growth and discovery. Ash would have to learn about the responsibilities of motherhood. He might start to understand May's struggles better from a mother's point of view. This could lead to a stronger bond between them. There could also be elements of mystery as to how and why this transformation occurred, and perhaps a quest to reverse it while still learning important life lessons along the way.
His relationship with Pikachu would become quite different. Pikachu might have to take on a more protective role. Instead of Ash being the one in charge, Pikachu would be looking out for Eevee - Ash. They would still have a strong bond, but it would be based more on Pikachu's guardianship now.
One possible fanfiction could be about Ash's adventures in Hoenn during the month of May. Maybe he discovers a new Pokémon species that is only active during this time of the year. He could be traveling with his usual companions and facing challenges specific to the Hoenn region.
