There could be a fanfiction where Ash is magically bound to obey a mysterious force. This changes his whole approach to Pokémon battles. Instead of his usual impulsive style, he has to carefully plan and execute his moves according to the commands of this force. It makes for a really different and exciting take on his character.
Well, the concept of Ash having to obey is interesting because it can completely change the dynamics of his relationships. His Pokémon, his friends, and his rivals will all interact with him differently. It also allows the author to explore different plotlines and scenarios that wouldn't be possible in the normal Pokémon storyline where Ash is more independent.
One common theme is the struggle between the hypnotized Ash and his true self. His friends often play a crucial role in trying to break the hypnosis and bring him back to normal. Another theme could be the power struggle between the one who hypnotizes Ash and those who want to free him.
One possible plotline could be that a villain uses a new type of Poké - ball technology to control Ash's mind and make him do their bidding, like stealing Pokémon from other trainers. Another could be a strange psychic Pokémon that accidentally takes over Ash's mind while trying to communicate, leading to some chaotic and comical situations as his friends try to figure out what's wrong and break the control.
