One idea could be a world where humans and Pokemon have to compete in a series of challenges to share resources. Another could be a Pokemon rebellion against humans who have been mistreating them.
Well, you could focus on the relationships. Maybe a Charmander - turned - human has a deep friendship with a Squirtle - human. They could be going on adventures together, facing challenges like normal humans but also having some unique Pokemon - related problems. For instance, they might be hunted by an evil organization that wants to use their Pokemon powers for bad things.
A plot could also revolve around a new type of power - enhancing crystal that has been discovered. Kyogre and Groudon both want it to boost their own strength. A group of trainers get caught in the middle of their struggle. They have to figure out a way to either stop the two Legendary Pokemon from fighting over it or find a way to share the crystal's power between them to maintain the balance in the world.
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.
One idea could be a world where humans and pokemon have to compete in a series of challenges for the right to co - exist in a new territory. Another could be a story where a human with special powers is pitted against a powerful pokemon in a battle of wits and strength. Maybe a pokemon trainer who loses their memory and has to rely on the help of their pokemon to figure out who they are while also facing off against other humans who want to take advantage of their situation.
One interesting idea could be exploring the relationships between Pokemon and humans in a more in - depth way, like a human having a telepathic bond with their Pokemon. Another is imagining a world where humans can transform into Pokemon temporarily for certain tasks or battles.
One interesting idea could be the exploration of Pokemon's unique abilities translated into human form. For example, a Pikachu - turned - human might have some sort of electrical power manifestation in a more human - like way. Maybe they can still generate electricity but through a different biological process, like their hands becoming conductors.
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.
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.
Well, you could have a story where a new type of Pokemon is discovered that has vampire - like characteristics, like draining the energy of other Pokemon instead of blood. The main character, a young trainer, has to figure out how to deal with this new threat. Or perhaps there's a vampire Pokemon that was once a normal Pokemon but was cursed. It then tries to find a way to break the curse while befriending a group of trainers.
