One idea could be a Pokemon that can shapeshift into different legendary Pokemon to gain their powers. For example, it could shift into Mew to use its psychic abilities in unique ways. Another idea is a shapeshifting Pokemon that disguises itself as other common Pokemon to play pranks on trainers. It could be really fun to write about the chaos it causes.
One idea could be a pokemon shapeshifter that is trying to hide its true form in a human - dominated city. It has to constantly adapt and learn human behaviors to avoid detection.
One plot idea could be Ash getting the ability to shapeshift accidentally. For example, he touches a strange Pokemon or an ancient artifact. Then he has to figure out how to control this new power while on his journey to become a Pokemon master.

Another interesting concept is to write a fanfic about a group of Pokemon that form a secret society. They have their own rules and goals, and the story could follow a human or a Pokemon who stumbles upon this society and gets involved in their affairs.
One idea could be a fanfic where a trainer discovers a new and rare Pokemon species in an uncharted region.

One idea could be that Harry uses his shapeshifting ability to spy on the Death Eaters unnoticed. He could transform into a small creature like a mouse and infiltrate their meetings.
One idea could be a dragon shapeshifter who is forced to hide in human form in a modern city. They have to constantly struggle to keep their true identity a secret while also being drawn to other magical beings in the city. Another plot could involve a dragon shapeshifter falling in love with a human, and having to decide whether to reveal their true form or not. Or perhaps a story where a dragon shapeshifter is on a quest to find a lost magical artifact that is crucial for the survival of their dragon clan.
One idea could be a story about a trainer who discovers a rare lemon - colored Pokémon in a hidden grove. The Pokémon has unique abilities related to nature, like making lemon - scented plants grow rapidly. This could lead to an adventure where the trainer has to protect the Pokémon from poachers who want to sell it on the black market.
One interesting idea could be exploring the more scientific aspects of Pokémon. For example, how their powers might be related to real - world physics or biology.

And also, perhaps a different take on the relationship between trainers and Pokémon, such as more equal partnerships rather than just the trainer being in control.

One idea could be creating an OC that is a hybrid of different Pokemon types. For example, a Pokemon with the features of a water - type and an electric - type. This could lead to unique abilities and an interesting backstory about how it came to be. Another idea is to have an OC that is a trainer from a far - off, unexplored region. This trainer could have different training methods and a whole new set of Pokemon not commonly seen in the main Pokemon world. You could also make an OC that is a Pokemon with a special power related to emotions, like it can heal other Pokemon's wounds when they are sad or boost their power when they are happy.
