In this fanfiction, Ash could be developed by making him more of a mentor. Since he's the champion, he has a lot to offer to younger trainers in Kanto. By teaching them, he would also learn more about himself and his own journey. He could also be shown struggling with the pressure of being a role model. Every move he makes is watched by others, and this could lead to some interesting character development. For example, he might make a mistake in a battle and then have to deal with the public's reaction, which would make him more self - aware and stronger in the long run.
Ash can be developed further by showing his insecurities as a champion. Maybe he starts to doubt if he really is worthy of the title, and this makes him train even harder. He could also develop new relationships with other trainers in Kanto, learning from them and teaching them in return. Another way is to show his growth in handling the political side of being a champion, like dealing with the Pokémon League's bureaucracy.
It could be about Ash achieving the ultimate goal of becoming the Kanto champion. Maybe it details his journey, the battles he had to overcome, and the growth he experiences along the way to claim the title.
I think Brock and Misty could be main characters too. They travel with Ash in Kanto. Brock with his knowledge of Pokémon care and Misty with her own skills as a trainer could play important roles in Ash's journey to become the champion in this fanfiction. Maybe they offer advice, support, or even join in some of the battles.
One plot idea could be Ash facing a new and powerful villain who has a vendetta against all the previous Kanto champions. This villain could be trying to rewrite the history of the Kanto region's Pokémon battles. Another idea is Ash having to defend his champion title against trainers from other regions who believe he doesn't deserve it because he's from a relatively small town. A third plot could involve Ash finding a rare and mysterious Pokémon in Kanto that has the power to either greatly enhance his team or put them in great danger, and he has to figure out how to handle it while still being the champion.
In the fanfiction, Ash's character development might be shown through his newfound patience. He used to be impulsive in battles sometimes, but after winning the league, he has learned to wait for the right moment to make his moves. His understanding of different Pokémon types and their abilities has also expanded significantly. He starts to see the bigger picture in Pokémon battles and not just focus on winning individual fights. This broader perspective helps him in planning his long - term training and battle strategies.
The unknown champion could be a reclusive hermit - like character who has been living in seclusion in a forest. They have trained their Pokémon in harmony with nature and have a very different approach compared to the more mainstream trainers. Maybe they are an old - timer who has seen different eras of Pokémon training.
Well, in an 'ash unknown champion' fanfiction, the plot might involve Ash getting lost in a mysterious region. There, he stumbles upon an unknown champion who is facing some sort of problem, like a group of poachers targeting their rare Pokémon. Ash decides to help the champion, and in the process, they exchange their Pokémon training techniques. As they work together, Ash realizes that there are so many new ways to approach Pokémon battles that he hadn't known before.
Ash can be developed by having him gradually notice Serena's yandere tendencies. At first, he might just think she's being a bit overprotective. But as it becomes more extreme, he could start to feel conflicted. For example, he loves Serena as a friend but is starting to be uncomfortable with her actions. This forces him to grow and become more assertive in setting boundaries.
It really depends on the specific fanfiction. Some might have them meeting early on, while others could have it happen later in the story.
A common theme is friendship. Ash and May's relationship as friends growing and evolving during their time in Kanto. Another theme is growth. Both of them grow as trainers, Ash in his battles and May in her coordinating skills.
Ash would likely be shocked at first. He's so used to seeing the good in people, especially fellow trainers. But then he'd probably get angry and determined to set things right. He has a strong sense of justice, so he wouldn't let the betrayal go unpunished.
