There might also be a villain who wants to use the power of fennel - influenced Pokemon for their own gain. This character would add conflict to the story and be a major antagonist for the other main characters to face.
Well, obviously Fennel is one of the main characters. She is often the center of the story due to her role as a researcher. Sometimes, the main character from the Pokemon games might also be a main character in the fanfiction, interacting with Fennel and helping her with her research or getting help from her in their own Pokemon journey.
I don't know as I haven't read it. It could be members of the Fennel family.
In some Pokemon fennel fanfic, there might be a story where a researcher discovers a new type of Pokemon evolution that is triggered by fennel. This could lead to all kinds of exciting plot twists as the trainer tries to find enough fennel to make their Pokemon evolve.
Since we don't know the exact details of 'the gathering pokemon fanfic', the main characters could be a group of young and enthusiastic Pokémon trainers. They might be on a journey to become the best and this gathering could be a crucial part of their adventure. It could also feature some Pokémon with special personalities as sort of secondary main characters, like a Pikachu that has a unique ability compared to others. Another possibility is that there are some wise old Pokémon trainers who are the main characters, guiding the younger ones during the gathering.
It could be the challenger themselves. They are usually the central focus, with their own personality, goals and dreams. Maybe they have a rival who is also a main character, constantly competing with them.
The Akatsuki members are the main characters. They bring their own unique abilities and goals. For example, Hidan's immortality could play an interesting role in the Pokemon world. He might be more reckless in battles because he knows he can't die easily. Kisame, with his shark - like appearance, could have an affinity for Water - type Pokemon and be really strong in underwater Pokemon battles. These characters' interactions with the Pokemon and each other are what drive the story in an Akatsuki Pokemon Fanfic.
It could be Pikachu as a main character. Since Pikachu is one of the most popular Pokémon, it would be likely to be involved in the story, perhaps bouncing on the trampoline and having a great time.
Obviously, Cheryl is one of the main characters. She's the center of the fanfic's story. Depending on the plot, her Pokemon would also be important characters. For example, if she has a Pikachu, that Pikachu would play a role in her adventures.
