In a fanfic about Ash as the Kalos champion, we could see him facing new challenges. Even though he's the champion, there could be powerful trainers from other regions who come to Kalos to challenge him. Ash has to constantly train and adapt his Pokémon team to defend his title, while also dealing with the pressure of being a role model for the young trainers in Kalos.
One possible fanfic could be about Ash's journey to become the Kalos champion. It might start with his arrival in Kalos, full of excitement and determination. He meets new Pokémon and friends along the way. His battles are intense, with him using unique strategies to defeat his opponents and gradually climb the ranks to the championship.
A fanfic centered around Ash as the Kalos champion could explore his post - victory life. He could be traveling across Kalos, sharing his knowledge and experiences with new trainers. Maybe he's involved in some special Pokémon conservation projects in Kalos, using his status as champion to make a positive impact on the region's Pokémon ecosystem.
One key element is the battles. Since it's about Ash as the Kalos champion, the battles need to be exciting and well - described. His Pokémon's moves, the strategies he uses, and the reactions of the opponents are all important. Another element is the relationships. His friendship with his Pokémon, his human friends in Kalos like Serena, Clemont, and Bonnie. And also his relationship with the Kalos region itself, how he explores and falls in love with the place.
A great plot twist could be that the Kalos champion turns out to be an impostor. Ash discovers this during his journey towards the championship. This would mean that all the battles leading up to the championship were based on a false premise. Ash then has to not only expose the impostor but also face the real champion in a series of unforeseen challenges. Also, there could be a twist where Ash's Pikachu loses its ability to use electricity temporarily, forcing Ash to rely on his other Pokémon in new and creative ways.
One idea could be Ash facing off against old rivals who are jealous of his new Kalos champion status. They challenge him in unique battles that test his skills in new ways.
A great 'Ash becomes Kalos Champion' fanfiction would have a strong sense of progression. Ash should start at a certain level and gradually become more powerful as he overcomes various obstacles in Kalos. The fanfiction could also explore the backstories of his Pokémon in more detail, like how they came to be with Ash and what their own goals are. Additionally, the way Ash interacts with the local Pokémon and trainers in Kalos can add depth and authenticity to the story.
One possible plotline could be Ash facing off against his toughest opponents in Kalos. He might have to battle against the Elite Four, each with their unique Pokémon and battle styles. Another aspect could be his relationship with his Pokémon evolving, like Pikachu learning a new powerful move just for these crucial battles. And of course, his friendship with his Kalos - based friends like Serena could play a big role, with them cheering him on and providing support in different ways.
His team might gain some new Kalos Pokémon. For instance, he could catch a Fennekin which later evolves into Delphox. This new addition would bring in new moves and abilities. Maybe he would also trade one of his existing Pokémon for a unique Kalos Pokémon that has a special advantage in the Kalos battles.
It could be a local Kalos trainer who has been training specifically to become the Kalos champion for years. This trainer might have a team of rare and powerful Kalos Pokémon and a very strategic battle style. He or she could see Ash as an outsider and a threat to their long - held dream of being the champion.
One likely betrayer could be Serena. Maybe she has some hidden motives that are revealed when Ash becomes champion. For example, she might be jealous of his success and the attention he gets as champion, and so she betrays him.
One possible plot could be that Ash's so - called friends in the Kalos region turn on him out of jealousy. Maybe they can't handle the fact that he has become the champion. They start spreading false rumors about him, which makes the public turn against Ash. This betrayal could lead Ash to question his own journey and the relationships he has formed.
One idea could be Ash facing a new, extremely powerful and mysterious Pokémon in the Kalos region that no one has ever seen before. This Pokémon could be the key to a hidden power within the Kalos champion title. Another plot could involve Ash having to team up with a former rival from his past travels to overcome a threat to the Kalos Pokémon ecosystem. Maybe there's a dark organization trying to disrupt the balance, and Ash's unique bond with his Pokémon is what's needed to stop them.
