Well, you could write a fanfiction where the evil team in the X and Y games has a different, more complex motive. Instead of just wanting power or to disrupt things, they believe they are saving the Pokemon world from a future threat that only they know about. And the main character has to decide whether to believe them or stop them, all while exploring the beautiful Kalos region and its unique Pokemon.
A plot could revolve around a Pokemon Contest in the Kalos region. The main character is not just aiming for victory but also trying to use the Contest as a platform to spread awareness about the importance of Pokemon and human relationships. They might face tough competition from other Contestants who have different views on how to present their Pokemon, and there could be some mystery elements related to some rare Pokemon that are said to enhance a Pokemon's performance in the Contest.
One idea could be Serena and Ash getting lost in a mysterious forest in the Kalos region. They have to rely on each other's skills and the Pokemon they have with them to find their way out. Along the way, they might discover a new and rare Pokemon species.
One idea could be Calem's journey after becoming the champion. Maybe he travels to other regions to learn new battle strategies and meet different Pokemon. Another could be a story where Calem has to team up with his old rivals to face a new, powerful threat to the Kalos region.
A great plot for Pokemon Adventures fanfiction could be centered around a Pokemon with amnesia. The trainer then tries to help the Pokemon remember its past, which leads them on a journey filled with various challenges and revelations. It could also involve the discovery of a hidden Pokemon society that has its own rules and customs. This would add an element of mystery and exploration to the story. Additionally, a story about a trainer who is able to communicate with Pokemon in a unique way, like through dreams or telepathy, could be really interesting.
A plot where Shauna participates in a high - stakes Pokemon tournament. She faces off against tough opponents, and each battle teaches her something new about herself and her Pokemon. The fanfiction could focus on her mental and emotional journey during the tournament, from the nerves before the first battle to the elation of victory or the disappointment of defeat.
One idea could be exploring an alternate version of the Gold story where the protagonist teams up with a rare and powerful Pokemon from the start. This would change the power dynamics and how he faces challenges.
One idea could be a story where the main character discovers a new and extremely rare Pokemon in an uncharted region. Another could be a tale of a Pokemon trainer who has to team up with their rival to save a group of endangered Pokemon from an evil organization. Or perhaps a story about a Pokemon with unique abilities that gets separated from its trainer and has to find its way back through various challenges.
A crossover with a superhero universe would be cool. Imagine Pokémon in a city full of superheroes. Charizard could team up with a fire - based superhero to fight a powerful villain. The Pokémon's unique abilities would add a new dynamic to the superhero battles.
One idea could be to focus on a new trainer's journey in the world of Pokemon Yellow. They could start with a Pikachu that has a unique ability not found in the original game.
One idea could be to focus on an underrated Pokemon's journey. For example, a Sentret that has big dreams of becoming a strong protector in the forest. It could face challenges like dealing with a group of mischievous Poochyena.
