A wolf in Pokemon fanfiction could be introduced as a mythical or legendary creature. It could have a deep connection with the lore of the Pokemon world. For example, it might be related to an ancient prophecy where its appearance signals a great change in the balance of the Pokemon ecosystem. The wolf could have powers that are both feared and respected by trainers and Pokemon alike.
It can fit by exploring Flannery's backstory more deeply. Maybe her 'futa' nature is related to some ancient Pokemon power or prophecy. For instance, she could be the key to unlocking a hidden aspect of the Pokemon world that has been forgotten over time.
I think Pokemon Black fits the story better. In Pokemon Black, the story has a darker and more complex tone. The themes of industrialization and its impact on the Pokemon world are more prominent. The Team Plasma's ideology in Black also seems to be more in line with the overall mood of the game, as they question the relationship between humans and Pokemon in a more profound way compared to Pokemon White.
Perhaps a trainer forces a Pokemon to do something it really doesn't want to do, like making a water - type Pokemon go into a really hot area. So the Pokemon throws a hissy fit, causing chaos in the area. It could start using its attacks randomly, and the trainer has to figure out how to calm it down.
Rachel would probably be paired well with a Fire - type Pokemon. She's passionate and determined, much like the fiery nature of Fire - types. Her ambition could be reflected in a Pokemon like Charizard, which is strong and has a big presence. Finn, on the other hand, might be suited to a Normal - type Pokemon. He's a bit of an all - around guy, like many Normal - types. His reliability could be similar to that of a Pidgeot. Quinn could be associated with an Ice - type. She can be cold and calculating at times, just like how Ice - types can be strategic in battles.
Cynthia could fit into the Pokemon Red world as a visiting expert. Since she's from Sinnoh, she could bring new knowledge about Pokemon training and battling. She might offer tips to the trainers in Kanto on how to better understand their Pokemon's abilities.
The diaper could also be related to a new type of Pokemon care. Maybe in a fan - made region, there are special diapers designed for Pokemon with certain needs. For Arceus, it could be a plot device to show how even the most powerful Pokemon can need special care. It could lead to interesting interactions between trainers and Pokemon, as they have to figure out how to take care of Arceus in this new state.
Pokemon Black fits the story in a way that emphasizes the struggle between different ideals. The presence of Team Plasma with their radical views creates a sense of conflict. In contrast, Pokemon White focuses more on the positive aspects of the Pokemon - human relationship. It shows how they can support and thrive together without the extreme conflict presented in Black.
Meowth from Team Rocket could also be a main character in such a fanfiction. He's always trying to prove himself to his bosses, Jessie and James. If things don't go his way during a mission to steal a powerful Pokemon, he could throw a hissy fit. He might start complaining loudly and making a scene, which could attract unwanted attention from other Pokemon or trainers.
Naruto would be quite the unique addition. He could use his ninja techniques to assist Bonnie in Pokemon battles. For instance, his tree - climbing skills could be useful in exploring areas where Pokemon are hidden. His ability to sense danger could also protect Bonnie and her Pokemon from potential threats in the wild.
