One idea could be a fanfiction where a girl joins Ash on his journey. She might have a unique Pokemon that helps Ash in a difficult battle. For example, she could have a psychic - type Pokemon that can sense the opponents' next moves and help Ash strategize better.
In a fanfiction, the girl could be from a different region with different Pokemon training methods. She teaches Ash new ways to bond with his Pokemon, like a special training regime that involves music and dance to boost the Pokemon's mood and performance.
In some fanfictions, the girl's clothes are related to her Pokemon evolution journey. Maybe when her starter Pokemon evolves, she gets a new set of clothes that symbolizes their growth together. It could be a more elaborate and powerful - looking outfit. Also, there are often stories where she dresses up to impress Ash or to show her confidence during a difficult battle. This could involve a flashy, battle - ready costume with bright colors and strong - looking boots.
Ash could be a Pokémon trainer with a different starting point in this fanfiction. Born in 1987, by 1997 he might have already made a name for himself in local Pokémon battles. He could have a team of Pokémon that he rescued from difficult situations, like a Charmander that was abandoned by its trainer. His story could revolve around giving these Pokémon a second chance and proving that Pokémon don't need to be 'perfect' to be strong.
In a fanfiction about Ash's reunion in Alola, perhaps he comes back to help with an ecological problem. The Alola region's unique ecosystem is in danger, and his friends call him for his expertise. Ash brings along some of his other Pokemon from his travels, and together they work to save the day while also having a great time catching up.
In this fanfiction, Ash and May could be on separate adventures in Kalos at first. But then, they cross paths when they both get involved in a mystery related to a rare and powerful Pokémon in Kalos. They have to put their heads together, along with their Pokémon, to solve the mystery and protect the Pokémon from those who would use it for bad purposes.
Another possibility is Ash becoming Lugia. Lugia is known as the guardian of the seas. As Lugia, Ash could explore the deep oceans, discover new species of Pokemon, and safeguard the marine ecosystem. He could use his psychic and flying abilities to interact with both water - and flying - type Pokemon, bringing a new era of harmony between different Pokemon types.
One idea could be that Ash discovers a hidden power within himself related to water types. Maybe he has a special connection with a rare water - type Pokemon that helps him unlock this new ability. For example, he meets a mythical water - type Pokemon in a hidden cave. The Pokemon sees Ash's pure heart and decides to bond with him, allowing him to control water in ways he never thought possible.
One idea could be that Ash discovers a Sylveon in a forest. The Sylveon is injured and Ash takes it upon himself to nurse it back to health. This could lead to a strong bond between them, and Sylveon could become a unique addition to his Pokémon team, with new adventures and battles ensuing.
Perhaps in the fanfiction, the baby is born with a unique Pokemon egg that hatches into a never - before - seen Pokemon. Ash and Misty then have to figure out how to raise this new Pokemon along with their child. It could be a Pokemon that combines the characteristics of some of their favorite Pokemon.
One idea is that Ash enters a hidden tournament where the rules are different. To compete, he has to endure intense physical training, which gradually makes him muscular. Another could be that a powerful Pokemon's aura has an impact on Ash's body, causing him to become more muscular as he spends time with it.
One idea could be that Ash discovers a hidden power within himself that allows him to communicate directly with Legendary Pokemon. This power sets him on a journey to understand the secrets of the Legendary Pokemon world. He might start by having an encounter with Mew, who guides him to different places where he can learn more about his new ability.
