One common theme is Ash achieving his ultimate Pokémon Master goal. In grown - up fanfics, he might finally win all the major championships. Another theme could be his relationships. Maybe he starts a family or has a more mature relationship with his friends like Brock and Misty. Also, there could be themes about him passing on his knowledge to a new generation of trainers.
Overcoming challenges together is a theme as well. Just like in the original series where Ash faces various Pokemon - related challenges, in these fanfics, he and his love interest face challenges related to their relationship, such as dealing with other people's opinions or finding time for each other while on their respective Pokemon journeys.
A common theme is friendship. Ash forms many bonds with his Pokémon and fellow trainers during his Kanto journey, and fanfics often explore these relationships further. Another theme is growth. Fans like to write about how Ash develops as a trainer in Kanto, learning new battle strategies and becoming more confident.
Well, often there might be themes related to vulnerability. Since diapers are associated with a more infant - like state, Ash could be in a situation where he's more vulnerable than usual. This might lead to scenarios where he has to rely on others more, which could be a central theme in the fanfic. Another theme could be about acceptance, with his friends accepting him in this different state.
Ash's appearance in a grown - up fanfic could change quite a bit. He could have a more mature look in his eyes, showing the experiences he's had. His clothing style might also be different. Instead of his usual cap and backpack, he could be wearing something more grown - up like a jacket and boots. And his skin tone might be a bit darker from all the time he's spent outdoors on his Pokémon adventures.
One common theme is the struggle between Ash's human - like nature and his new vampire instincts. For example, he might struggle with the urge to drink blood while still wanting to be kind to his Pokemon friends.
One common theme is family love. Delia is Ash's mother, so fanfictions often explore the deep love and support she gives to Ash. Another theme is Ash's growth, and how Delia has influenced that growth over the years.
Friendship is a very common theme. Ash and Joy often form a strong bond in these fanfictions, relying on each other in different situations. Another common theme is adventure. They might go on quests together, exploring new places and encountering new Pokémon.
One common theme is Ash's strategic brilliance in Pokémon battles. Instead of relying solely on his Pokémon's strength, he uses his intelligence to create battle plans that surprise his opponents.
One common theme could be Ash being betrayed by his friends in the Pokémon world. For example, they might leave him for a more powerful trainer or because of a misunderstanding. Another theme could be betrayal by the Pokémon League, like being wrongly disqualified from a major tournament. Also, some fanfictions may explore Ash being betrayed by a new character who has ulterior motives and tries to undermine his journey.
Adventure is also a popular theme. They could embark on a journey together to discover a new type of Pokémon or a hidden place in the Pokémon world. Along the way, they face various challenges and obstacles, which they overcome with their combined skills and the bond between them.
