In Paldea, the interactions could change because of the different cultures and Pokemon battles. For example, if there are new battle styles in Paldea, Ash would be eager to learn and participate. Team Rocket might try to disrupt these battles to steal Pokemon. But as they interact more, they could start to understand each other better. Ash could see that Team Rocket might be more desperate for success in this new region, and Team Rocket could see Ash's determination to adapt and grow.
One possible plotline could be that Ash and Team Rocket accidentally team up in Paldea to face a common enemy. Maybe there's a powerful and mysterious Pokemon in Paldea that's causing chaos and they realize they need to combine their efforts to stop it. Ash could bring his skills and positive attitude, while Team Rocket could use their sneaky tactics in a good way for once.
One idea could be that Ash and Dawn visit Paldea for a special Pokemon exchange event. They meet new Pokemon and trainers, and Ash gets into some friendly battles with the local champions. Dawn, on the other hand, discovers new forms of Pokemon contests in Paldea and decides to participate.
The plot could revolve around Ash and Dawn being chosen to represent their home regions in a big Paldean Pokemon tournament. They train hard together, learning new techniques from Paldean trainers. However, they soon discover that there is a conspiracy to rig the tournament, and they have to expose the plot while still competing.
Yes, in some Team Rocket fanfictions, Ash can be depicted in various ways that might involve him having some sort of connection to Pokémon in a different light. Maybe he could be experimented on by Team Rocket to gain Pokémon - like abilities, or be transformed into a Pokémon - like being in a very creative and out - of - the - box fanfiction concept.
Typically, his old team could include Pikachu, of course. Then there might be Charizard, Bulbasaur, Squirtle, and others like Greninja. These Pokémon have been with Ash through different adventures in various regions.
One possible strongest team could be Pikachu, Charizard, Greninja, Lucario, Sceptile, and Infernape. Pikachu has been with Ash since the start and has a strong bond. Charizard is extremely powerful. Greninja has its unique form and great combat skills. Lucario is a very capable fighter. Sceptile was a strong addition to Ash's team in Hoenn. And Infernape showed great power in Sinnoh.
In fanfiction, Ash's secret Pokémon team could consist of some rare and powerful Pokémon. Maybe he has a shiny Charizard that he's been training in secret. It could have unique moves and a super strong bond with Ash, making it a formidable addition to his team.
In some fanfictions, the team plasma experiments on Ash might be centered around his special powers. For example, if Ash has some latent psychic ability related to Pokémon communication that they want to unlock and control. They could be using all sorts of unethical methods to figure out how his mind works when it comes to Pokémon training and battles. And they might also be looking at his physical endurance and how he can withstand tough Pokémon battles without getting overly tired, perhaps to create super - trainers of their own.
