In this fanfiction, Ash's father might be a trainer who lost his memory. He has been traveling around the Pokémon world without realizing he has a son. One day, Ash might cross paths with him during his own journey, and through a series of events, his father's memory could be restored.
In some Pokemon fanfictions, there could be creative interpretations where Ash is made out to be Red's father. However, in the official Pokemon canon, there is no such relationship between them.
Well, it could be really exciting. Ash already has his Pokémon journey skills, and adding the Force to it would make him super powerful. He could use the Force to sense where rare Pokémon are, or to communicate with them on a deeper level. Maybe he could even use it to enhance his Pokémon's abilities during battles, like giving Pikachu an extra boost of speed or power.
Another idea is that the discovery of Giovanni as his father makes Ash question his own identity and place in the Pokémon world. He might have to reevaluate his goals and his relationships with other characters. Meanwhile, Giovanni could be faced with the challenge of trying to make amends or trying to bring Ash into his world in a more positive way.
One plot idea could be that Ash's father was exiled from their town for a crime he didn't commit. The fanfiction could follow his journey to prove his innocence and his attempts to reunite with his family. Along the way, he could encounter unique Pokémon and make new friends who help him in his quest.
It could be a famous Pokémon trainer. Maybe someone who has traveled to many different regions and has a lot of knowledge about rare Pokémon.
One possible storyline could be that Ash has to go undercover in a dress for a special mission. Maybe he's trying to infiltrate an all - female Pokémon training group where men are not allowed. So, he dons a dress to blend in and learn their secrets.
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.
It could be about Ash encountering Giratina in a strange new region. Maybe Giratina is causing some sort of chaos, and Ash has to figure out how to calm it down and understand its motives.
I'm not entirely sure as I haven't read a specific 'ash ketchum diaper fanfiction' myself. But it could potentially be a fan - created story that involves Ash Ketchum in some sort of situation related to diapers, perhaps in a humorous or out - of - the - ordinary way that fans like to imagine within the context of the Pokémon universe.
I'm not entirely sure as 'ash ketchum slave fanfiction' isn't a mainstream or positive concept. It might be some very unorthodox and inappropriate fan - created story that goes against the normal values associated with the Ash Ketchum character. It's not something that should be promoted.
