An interesting OC for a Pokemon XY fanfiction could be a Pokemon chef. This OC could travel around the XY region, looking for rare ingredients that can be used to make special Pokemon food. The food they make could have various effects on the Pokemon, like increasing their speed or enhancing their special abilities. Another idea is an OC who is a time - traveler from the future. They come to the XY region to prevent a great disaster that will happen to the Pokemon in the future. And, an OC that's a Pokemon psychic, but not in the typical sense. Instead of just reading minds, they can enter the dreams of Pokemon and help them overcome their fears or traumas.
Well, you could have an OC that is a Pokemon breeder with a special talent for breeding rare and powerful Pokemon. This OC could be on a quest to find the perfect combination of Pokemon in the XY region to create a new and unique species. Or, an OC who is a Pokemon ranger but with a twist - they can transform into a Pokemon - like form for a short time, which gives them an edge in protecting the wild Pokemon in the XY region. Also, an OC that's a Pokemon artist, who travels around the XY region painting pictures of different Pokemon. Their art has a magical effect on the Pokemon, making them stronger or more friendly.
One idea could be a story where the protagonist's starter Pokemon has a rare hidden ability that they discover during a crucial battle. This ability gives them an edge and changes the course of the battle and the overall story. Another idea is a fanfic that focuses on the relationship between the Pokemon and their trainers in the 'pokemon xy' game world, exploring how they communicate and support each other on their journey.
One idea could be Sonic getting transported to the Pokemon XY world. He could use his speed to help trainers catch fast - moving Pokemon. For example, he could outrun a Pikachu and lead it towards a trainer's Pokeball.
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.
Another interesting crossover could be the appearance of Chaos Emeralds in the Pokemon XY world. Pokemon might be attracted to the powerful energy of the Chaos Emeralds. This could lead to a situation where both Sonic and Pokemon trainers have to protect the Chaos Emeralds from an evil force that wants to use their power to control both the Sonic universe and the Pokemon XY world.
One interesting plotline could be a unique take on the relationship between Ash and his Pokémon in this abridged fanfiction. Maybe his Pokémon develop some unexpected abilities or personalities. Another could be a new rivalry for Ash that is more complex and engaging than in the original. For example, the rival might have a hidden agenda that slowly unfolds throughout the story.
There are many great ones. Some focus on the unique abilities of Kyle and how an original character (OC) might interact with him. For example, an OC could be a new student at the school Kyle attends, and their relationship could start with curiosity and grow into a deep friendship. They might help each other understand different aspects of the human world that Kyle is still learning about.
Perhaps an OC who is a Pokemon researcher. Instead of focusing on battles, they study Pokemon behavior and evolution. They encounter a rare Pokemon that seems to be evolving in an unexpected way. The OC then devotes their time to understanding this phenomenon, traveling across different regions, and meeting other trainers and Pokemon along the way.
An interesting Pokemon evil OC could be a wealthy heir who uses their resources to create an underground Pokemon fighting ring where Pokemon are forced to fight to the death. They believe that only the strongest Pokemon should survive and see regular Pokemon training as weak. This OC could have a group of enforcers made up of powerful and intimidating Pokemon that keep the other trainers in line.
You could write an OC fanfiction where the OC is a Pokemon scientist in the Insurgence world. They are researching a new form of Pokemon evolution that has been triggered by the strange events in the game. The OC could face challenges like lack of resources, opposition from other Pokemon communities, and the danger of the evolving Pokemon going out of control. This would allow for a lot of exploration of the scientific aspects as well as the social and political ones in the Insurgence universe.
