Well, in the fanfiction, perhaps Ash catches Meowth to try and reform it. He might see that Meowth is not really a bad Pokémon at heart, just following the wrong crowd in Team Rocket. So he takes it under his wing, and they start to develop an unlikely friendship which changes both of them for the better.
Meowth joining Ash in a fanfiction could also lead to some interesting character development for both. Ash might learn more about the Pokémon world from Meowth's perspective, especially the seedy side that Meowth has been a part of with Team Rocket. And Meowth could learn about friendship and loyalty in a new way, different from what he's experienced with Jessie and James.
If Ash catches Meowth in the fanfiction, it would be a huge blow to Team Rocket. Meowth is the translator for their Pokémon, so without it, they would have a hard time communicating their plans to their Pokémon. This could lead to a lot of failed missions.
The storyline would likely become more complex. With Meowth around, there would be a new dynamic. His loyalty would be split between Ash and his old Team Rocket pals at first. This internal conflict could drive parts of the story.
Meowth's origin story is quite interesting. He grew up in an alley where he had to fight for food. He was often bullied by other Pokémon. But one day, he saw a human using money to buy things. That's when he decided he wanted to be part of the human world. So he started learning human ways, which included learning to speak and walk like them. His journey wasn't easy, but his strong will led him to become the Meowth we know today.
Well, perhaps it's a story that focuses on the friendship between Meowth and Bonnie. They might help each other out in their respective dreams. For example, Bonnie might be trying to become a better Pokemon trainer with Meowth's street - smart knowledge of the Pokemon world.
Another plot could be a time - travel story. Meowth and Bonnie somehow get sent back in time to a crucial moment in Pokemon history. They have to figure out how to get back to their own time while also making sure they don't disrupt the past too much. During this adventure, they rely on each other's unique skills and form a strong friendship.
One great meowth x pikachu fanfic is 'Adventures of Meowth and Pikachu'. It shows their unique friendship in a really interesting way. They go on quests together and face challenges side by side.
He might meet Pikachu first. Since Pikachu is his closest and most loyal Pokemon friend, it would be likely that Pikachu would be by his side when he wakes up. Pikachu could be really confused at first but still show concern for Ash in his new state.
One idea could be to explore Ash's first encounter with Pikachu from Pikachu's perspective. Maybe Pikachu was initially scared of Ash but then grew to trust him over time. Another idea is to write about Ash's first gym battle in a more detailed and dramatic way, like adding some internal thoughts of Ash during the battle.
