A plot could be that there is a powerful dark force threatening the Pokémon world. Ash, Cynthia, and Diantha are chosen as the ones who can stop it. They start by gathering information in different regions. Ash uses his experience from traveling around, Cynthia taps into her research, and Diantha uses her connections. As they come together, they face many challenges like battles with the minions of the dark force, solving puzzles related to ancient Pokémon powers, and finally, they combine their efforts to defeat the dark force and save the Pokémon world.
Maybe the plot is about a lost Pokémon species that is said to have the power to heal any Pokémon. Ash, Cynthia, and Diantha hear about it and set out on a quest to find it. Along the journey, they face rival trainers who also want to find the Pokémon for their own reasons. They have to outwit these rivals, brave difficult terrains, and finally, when they find the Pokémon, they have to decide what to do with its power. Ash might want to use it to help all Pokémon, Cynthia might want to study it more, and Diantha might want to protect it from those who would misuse it.
One idea could be a story where Ash, Cynthia, and Diantha team up for a special Pokémon tournament. They each bring their unique skills and Pokémon teams. Ash's determination, Cynthia's strategic mind, and Diantha's grace would make for an interesting dynamic as they face tough opponents together.
