One idea could be to create an OC who has a unique ability that no other Pokemon trainer has. For example, the ability to communicate telepathically with all Pokemon types. This could lead to all kinds of interesting interactions and storylines, like befriending a wild and usually hostile Pokemon easily. Another idea is to have an OC SI from a different world or dimension where the rules of Pokemon are different, and they have to adapt to the new world while also sharing their own knowledge.
An interesting concept for a Pokemon OC SI fanfic is to have an OC who is reincarnated as a Pokemon. This OC would then have to figure out how to live as a Pokemon, deal with Pokemon society, and perhaps even find a way to transform back into a human. They could also have memories of their human life and use that knowledge to their advantage, like knowing which berries are poisonous to humans but not Pokemon, and using that to help other Pokemon in need.
You could base your Pokemon OC SI fanfic on an OC who has a special goal. For instance, an OC that wants to create a Pokemon sanctuary for all the endangered or mistreated Pokemon. They would travel around the Pokemon world, facing various challenges like poachers and natural disasters, all while trying to rescue and rehabilitate Pokemon. It would make for an exciting and heart - warming story.
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.
An interesting OC for a Pokemon Kalos fanfic could be a young artist who uses their Pokemon as models for their art. They travel around Kalos in search of inspiration and different Pokemon species to paint. Along the way, they meet other trainers and get involved in battles not just for victory but also to observe how Pokemon move and interact, which helps them in their art. This OC could also have a Pokemon with a unique coloration that they discovered during their travels.
One idea could be to create a story where two female Pokemon trainers from different regions meet during a big Pokemon tournament. They start off as rivals but gradually develop a deep bond as they discover they have more in common than they thought. For example, they both might have a special connection with a certain type of Pokemon, like Eevee. This shared interest could be the starting point of their relationship.
One idea could be an SI (self - insert) as a sidekick to a well - known super hero. They could start off with no powers but gradually develop unique abilities through their adventures. For example, they might gain the power to manipulate energy after being exposed to a strange alien device during a battle.
You could create an OC that is a trainer from a small village in Kalos who has a special bond with a Furfrou. Maybe their family has been breeding Furfrou for generations, and this OC's goal is to show the unique styles of Furfrou in Pokemon contests.
Maybe Lemon is a Pokemon OC who is part - Pokemon herself. For example, she could have the features of a Pikachu, like the cute cheeks that can store electricity. The fanfic could explore how she tries to fit into both the human and Pokemon worlds, facing challenges such as being accepted by other humans and Pokemon alike. It could also involve a plot where she has to use her unique abilities to save her friends from an evil organization.
A really interesting plot might be that the Eevee is actually a reincarnation of a great Pokemon hero from the past. The trainer discovers this as they journey together and face various challenges. This knowledge makes them a target for an evil organization that wants to use the Eevee's power for their own malicious purposes. Along the way, the Eevee and the trainer meet other Pokemon and trainers who either help or hinder them in their quest to protect the Eevee's secret and fulfill its destiny.
One idea could be that the OC male is a trainer who discovers a rare female Pokemon with special powers. He decides to train her and they form a strong bond as they face various challenges together. Another could be a story where the female Pokemon is in danger and the OC male has to go on a quest to save her, encountering other Pokemon and trainers along the way.
One idea could be creating an OC that is a hybrid of two different Pokemon types. For example, a half - water, half - electric type with unique abilities. Another idea is to make an OC that has a special bond with a legendary Pokemon, perhaps they are the chosen one to help the legendary in a time of crisis. Also, you could have an OC from a different region with a completely new set of Pokemon not seen before in the main series.
One idea could be to create an OC that has a unique typing combination not commonly seen, like a Ghost/Grass type. This could lead to interesting storylines in the fanfiction, such as how they interact with other Pokemon and trainers. Another idea is to give the OC a special ability that sets them apart. For example, an ability that allows it to communicate with wild Pokemon more effectively, which could be useful in various fanfiction scenarios.
