Well, if Ash turns into a Pikachu in a fanfiction, it would be quite a transformation. Firstly, his communication with Pikachu would become more of an internal dialogue. And he'd have to get used to moving around on all fours and using Pikachu - like movements. His battles would be completely different too. He'd be relying on Pikachu's natural skills rather than his own battle strategies as a human trainer.
Team Rocket could still be the main antagonists. They might see Ash as a Pikachu and try to capture him more than ever, thinking he's a special Pikachu. Maybe they believe he has some sort of new power because of his transformation.

Well, in such a fanfic, a cool plot point might be that Ash, as a Pikachu, has to communicate differently. Since he can't talk like a human anymore, he has to find new ways to convey his thoughts and ideas to his friends. Also, there could be a plot where he discovers new powers that normal Pikachu don't have because he was once human. For example, he might be able to strategize better than a regular Pikachu in battles.
Well, in some 'pokemon ash turns to stone fanfiction', Ash might turn to stone because of a strange magical artifact. His Pikachu refuses to leave his side and tries to find a way to bring him back. This could lead to Pikachu having to communicate with other Pokémon in ways it never has before, like using telepathy or special signals. Maybe there's a part where Pikachu teams up with Misty and Brock, and they discover that the only way to reverse it is by finding a lost temple with a special crystal.

One possible scenario could be that Pikachu is exposed to a strange type of energy. This energy mutates its genetic structure, slowly transforming it into a human form. At first, Pikachu might be confused and scared, not understanding its new body. But as time passes, it starts to learn about human ways, like walking on two legs and using its hands to pick things up.
In this type of fanfiction, Ash is at the core. But it's not just him. His Pokémon are crucial. Pikachu, being his closest partner, will often be the most active in trying to find a solution. Then there are his human friends. Misty, with her knowledge of water Pokémon and her feisty personality, might be the one who comes up with ideas on how to approach the problem. Brock, with his medical knowledge of Pokémon, could be trying to figure out if there's a way to reverse the stoning process from a scientific angle.
Well, Pikachu's popularity in fanfics is no surprise. It's been the face of Pokemon for a long time. In fan-written stories, Pikachu can be depicted in various ways. Sometimes it's a super powerful version of itself, being able to defeat even the toughest of opponents single - handedly. And since it's so well - known, readers are immediately drawn to stories that feature Pikachu, whether it's a story about its origin or its future adventures.
