He could have adventures exploring new regions in the Pokemon Horizons universe that haven't been shown in the main series. Maybe he discovers a hidden island full of rare and unique Pokemon.
Some fanfictions might show Ash becoming a sort of honorary Pokemon Ranger. He would then have to balance his duties as a Trainer and as a Ranger. This could create internal conflict for him as he tries to decide which role is more important at different times. His friends from the Pokemon journey, like Brock and Misty, could also be involved, adding more layers to the story.
Ash could have adventures like exploring a hidden part of the school that has a connection to a rare Pokemon. Maybe there's an old library in the school that holds secrets about legendary Pokemon, and Ash stumbles upon it during a game of hide - and - seek with his new friends.
One great aspect of a fanfiction where Ash starts in Kalos is that the environment is so different from what he's used to. The Kalos region has its own set of challenges, like the mega - evolution phenomenon. Ash could get involved with researching about it early on. He might also form new friendships with characters like Serena right from the beginning, and together they could embark on a journey filled with new discoveries and exciting battles.
Ash might develop a deeper understanding of Pokemon relationships in the fanfiction. He could observe how different trainers in the new setting interact with their Pokemon and apply those lessons to his own relationships. For instance, he might learn about a special bond that a trainer has with a Pokemon that allows them to communicate telepathically. This could inspire Ash to explore different ways of connecting with his own Pokemon, leading to his character growth.
One storyline could be about Ash finding a lost and injured Pokémon as his new partner. For example, if his new partner is a Togepi. He could nurse it back to health and in the process, form a strong bond. As Togepi grows, it could learn new moves and help Ash in gym battles, especially against fairy - type opponents.
He might go on adventures to find different Eevee evolutions. Since Eevee can evolve into many forms like Vaporeon, Jolteon, and Flareon, Ash could search for special stones or places that trigger these evolutions. He could also enter Eevee - only competitions in the fanfiction world.
Well, in an Ash goes to Pokemon school fanfiction, there could be a lot of fun interactions. Ash is used to traveling and learning on the go. At school, he'll likely get into some friendly rivalries. He might also discover new types of Pokemon that he hasn't seen much in his travels. And who knows, he could even start a Pokemon club at school.
In fanfiction, Ash could have many new Pokemon adventures in Kalos. He might meet new Pokemon species unique to Kalos, like Greninja. He could also face off against new trainers with different battle styles. And perhaps make new friends along the way who help him understand the Kalos region better.
Well, imagine a scenario where a dark force is spreading across both their worlds. Ash and Sakura are chosen to be the ones to stop it. Ash brings his team of Pokemon, and Sakura brings her ninja skills. They travel through different regions, from the lush forests of the Pokemon world to the hidden villages of the Naruto world. Along the way, they meet new characters, some of whom join their cause, and others who try to stop them. They have to learn to work together, with Ash teaching Sakura about Pokemon training and Sakura teaching Ash some basic ninja moves.
Begin with Ash's character. Consider his growth and development throughout the Pokemon series. You could write about a time when Ash has to face his biggest fears in a new Pokemon world. It could be a world where the rules of Pokemon battles are different, forcing him to adapt in new ways.
