One idea could be a person turning into a Pikachu and having to navigate the Pokemon world while still retaining some human memories and emotions. They might struggle with using Pikachu's electric powers at first.
A more complex idea could be a person turning into a Legendary Pokemon, say Mewtwo. They would have to deal with the power and the responsibility that comes with such a powerful form. Also, other Pokemon might either revere or fear them, and they would have to figure out how to interact with both humans and Pokemon in this new state.
One idea could be that a regular pokemon gets exposed to a strange, ancient energy that starts its transformation into a legendary. For example, a Pikachu accidentally stumbles upon an old, forgotten shrine in a forest and absorbs some of the mysterious energy there. Another plot could involve a pokemon trainer who has a special bond with their pokemon, and through that bond, the pokemon begins to evolve into a legendary form to save the trainer from a great danger. Maybe a Charizard turns into a Moltres - like form to battle an extremely powerful enemy threatening its trainer's life.
One idea could be a group of friends on a scientific expedition who accidentally get exposed to a strange energy that starts to turn them into Pokemon. Another could be a single character who wishes so hard to be a Pokemon to escape a difficult human life and slowly begins the transformation. Maybe a whole town gets affected by a magical spell that turns them into Pokemon and they have to figure out how to reverse it while living as Pokemon.
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. Another could be a story about a Pokemon that has unique abilities and how it changes the Pokemon battles in a particular area. Maybe a fanfic that focuses on the friendship between a trainer and a Pokemon that is usually considered difficult to train.
The exploration of the Pokemon - vampire relationship. How do other Pokemon react to those that have been turned? And how do trainers deal with their once - friendly Pokemon now having a thirst for blood? This creates a whole new set of storylines and character interactions within the fanfic.
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. Another idea could be a more in - depth look at the Pokémon society, like their culture and economy. 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.
A 'pokemon pov fanfic' could be about a Charizard that was abandoned by its trainer. The Charizard's POV could show its feelings of betrayal, how it struggles to survive on its own in the wild, and its journey to find a new purpose or a new group of Pokémon to belong to.
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.
One idea could be a story where a trainer is possessed by the spirit of a legendary Pokemon. This possession gives the trainer unique powers and insights into the Pokemon world. They can use these new abilities to face tough challenges and uncover hidden secrets.
