You could write about a group of friends in the Pokemon White world who embark on a journey to find a legendary Pokemon that is said to have the power to heal the land. Along the way, they face various challenges and grow as trainers.
One idea could be to focus on a trainer who discovers a rare and powerful Pokemon that no one has ever seen before in the Unova region. They then have to protect it from evil organizations who want to use it for their own gain.
One idea could be a story about a trainer who discovers a rare and powerful Pokemon in an unexpected place in the Unova region. This Pokemon has unique abilities that no one has ever seen before.
You could create a fanfic where the main character is a Pokemon Ranger working in Unova. Their mission could be to stop an illegal Pokemon trading ring that is stealing rare Pokemon from the wild. Along the way, they form bonds with different Pokemon and trainers, and they have to use their Ranger skills, like using the Capture Styler, to solve problems and catch the bad guys.
Another interesting concept is to write a fanfic from the perspective of a Pokemon in the Black and White world. For example, a Patrat that is part of a group trying to protect their territory from human encroachment. This would give a unique view into the Pokemon - human relationship and how Pokemon live in their natural habitats.
For a Pokemon Black and White fanfiction, you could write about a group of friends who all start their Pokemon journeys together. They each have different goals and Pokemon teams. As they progress, they face rivalries not only from other trainers but also from a mysterious new organization that is trying to disrupt the balance in the Unova region. This organization could be trying to control certain types of Pokemon for their own gain. The friends then have to work together, using their unique Pokemon skills and strategies, to stop this organization and protect the Unova region and its Pokemon. This type of story would allow for a lot of character development and exciting battles.
One idea could be exploring an alternate ending where the main villain has a change of heart before the final battle. Another could be a story centered around a new Pokemon species discovered in the Unova region post - game events. Maybe a fanfiction about a trainer who has to team up with a former rival to face a new, unexpected threat in Unova.
Well, a plot could revolve around Janine being involved in a Pokemon tournament where she uses her unique Poison - type Pokemon in unexpected ways. She might face some opponents who underestimate her because of her small stature but she proves them wrong with her brilliant strategies. Or perhaps a story where Janine discovers an ancient Pokemon artifact that has the power to control all Poison - type Pokemon and she has to protect it from evil forces.
A great plot could involve a world where Skin Pokemon are the outcasts because their changing abilities are seen as untrustworthy. A group of trainers decides to prove that Skin Pokemon are just as loyal and worthy as any other type. They form a sort of rescue team for Skin Pokemon in danger and work towards changing the perception of these unique creatures in the Pokemon world.
Maybe a fanfic where a trainer gets transported into the Pokemon world from our own world. They have to quickly learn the rules and make friends with Pokemon to find a way back home while also exploring the different regions and their unique Pokemon.
One idea could be a Pokemon scientist discovers a new type of Pokemon evolution that is triggered by an unusual environmental factor. For example, a certain type of rare crystal found deep in a cave that causes a Pokemon to evolve into a form never seen before. Another plot could involve a scientist trying to find a way to communicate with Pokemon on a deeper level, perhaps by creating a device that can translate their thoughts. Or, a Pokemon scientist might be on a quest to understand why some Pokemon have unique abilities that seem to go against the known laws of Pokemon biology.
A great plot could involve a group of friends in Alola who enter a Pokemon tournament with their underdog team. They face tough opponents but through their bond with their Pokemon and some clever strategies, they start to make a name for themselves in the tournament. Along the way, they also learn more about the different Alola Pokemon species and their habitats.
