One possible fanfiction could involve Team Rocket using a new device to hypnotize Ash Ketchum. They might make him do silly things like singing a Pokémon theme song in a really strange voice or making Pikachu do a little dance. But of course, his friends would eventually figure out what's going on and try to break the hypnosis.
One possible fanfiction could be where a powerful Pokémon trainer with psychic abilities hypnotizes Ash Ketchum. In this story, the trainer might have an evil plan to use Ash to steal rare Pokémon. Ash, under the hypnosis, starts to obey commands against his will. However, his Pikachu senses something is wrong and tries to break the hypnosis by using its electric shocks on Ash at just the right moment. Eventually, Ash breaks free and battles the evil trainer.
At first, Ash would be in shock. But then, he would likely turn his focus on finding out the truth. He's not one to give up easily. He'd start investigating what led to his betrayal. He might even go on a journey within the RWBY world to find evidence to clear his name and expose those who really are at fault. He'd still hold out hope that his former friends would see the truth and come back to his side.
Maybe a new, mysterious villain who has a grudge against Ash or wants to use his skills for their own evil purposes. This villain might be from a far - off region and has special powers that allow them to hypnotize people. They see Ash as a useful tool to carry out their plans in the Pokémon world.
His rival, Gary, could be a likely candidate. Gary has always been competitive with Ash, and in this fanfiction, his jealousy could reach a boiling point, causing him to betray Ash for his own gain, like trying to steal his Pokémon or get credit for his achievements.
Ash could become more confident and wise as a Dragon Master. His decision - making skills would improve as he deals with powerful and often unpredictable dragon Pokémon.
There are many family - friendly Ash Ketchum fanfics. Some might focus on his adventures in different regions, like his journey in the Alola region where he forms new friendships with Pokémon and trainers. These fanfics can be about his growth as a trainer, how he overcomes challenges in battles, and his bond with Pikachu in new and exciting scenarios.
One possible plot could be that Ash, being from a different world, is initially welcomed into the RWBY universe. But then, he might be betrayed when his Pokémon powers are seen as a threat. Maybe the RWBY characters fear that his abilities could disrupt the balance of their world. For example, if his Pikachu's electricity causes unexpected power surges in a world that has its own unique energy sources like Dust.
