One popular 'Ash grown up' fanfiction might involve him becoming a world - renowned Pokémon master, traveling to new and unexplored regions with his fully - evolved team. He could be facing new challenges like mega - evolved Pokémon in the hands of powerful trainers.
Some plotlines in Ash - grown - up fanfictions involve him taking on a more leadership role. For example, he could be in charge of a new Pokemon league or organization. This would put him in a position to make important decisions about the future of Pokemon training. He might also have adventures that are more complex and dangerous, like dealing with a powerful villain who threatens the entire Pokemon world. And of course, there could be a love story involved, perhaps with a long - time friend or a new character he meets.
In a grown - up fanfiction, Ash could be developed by giving him new goals. For example, he could aim to not only be the best Pokémon trainer but also to make a positive impact on the Pokémon world through conservation efforts. Misty could be developed by showing her taking on more responsibilities in the Pokémon community. She could be involved in international Pokémon events, representing water - type Pokémon. Their relationship could develop as they support each other in achieving these new goals, and they might also have to overcome misunderstandings and external pressures.
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.
Another idea is that all the characters are now parents themselves. They have to balance their work at Monsters Inc with raising their own little monsters. It could show how they use their experiences as scared kids or scarers to be better parents.
I'm not sure specifically as there could be many novels with this title. But generally, it might be about the journey of characters as they transition from childhood to adulthood, dealing with new responsibilities, relationships, and self - discovery.
First, decide on the direction you want Ash's growth to take. Will he be a more powerful trainer, or perhaps take on a different role? Then, think about the new characters or Pokémon you want to introduce. For example, if he's a trainer, what new and rare Pokémon will he catch? Also, consider the setting. Is it a new region or an evolved version of an existing one?
One idea could be that Ash becomes a world - renowned Pokémon master and Misty is a successful water - type Pokémon gym leader. They reunite after years apart and realize their feelings for each other have deepened. They then embark on a journey together to explore new regions and discover rare Pokémon.
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.
