The Pokemon mother beast itself can be considered a main character. It has its own personality and motives within the fanfiction. For example, it could be a gentle and wise being that guides other Pokemon.
Perhaps a plot where the Pokemon mother beast is in danger. Some evil organization wants to capture it for its powerful abilities. A young trainer then decides to protect it, embarking on a dangerous journey filled with battles and challenges.
Obviously, Ash is one of the main characters. Since it's about him being a legendary Pokemon in this fanfiction, he's central to the story.
Obviously, Nate is a main character. His Pokemon are also important characters in the fanfiction. Depending on the story, there might be other trainers that Nate meets during his journey, like a rival trainer who constantly challenges him.
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'm not sure specifically as it depends on the particular fanfiction. It could be a young trainer with a special dragon - type Pokemon like a Charizard or Dragonite.
Another possible main character in the fanfiction could be a Pokemon that has a special connection with Conway. Let's say it's a Pikachu that has some unique abilities. This Pikachu might have been abandoned by its previous trainer and Conway takes it in. Their relationship then becomes a central part of the story, with the Pikachu helping Conway in battles and Conway protecting the Pikachu from danger.
Obviously, Yancy is a main character. She is usually the central focus of the story. Her Pokemon are also important characters. For example, if she has a Pikachu, that Pikachu would play a role in battles and in her emotional journey. Sometimes, there might be a rival trainer who challenges Yancy and becomes a significant character in the fanfiction.
It's hard to say without reading it, but it could be trainers who are really into evolving Pokémon.
In many Pokemon Anabel fanfictions, her friends or allies can be main characters. They might help her in her quests or battles. Sometimes, a rival trainer can also be a main character. This rival often challenges Anabel, driving the plot forward through their competitive relationship. And let's not forget the Pokemon she befriends or battles against, which play important roles as well.
It could be some well - known Pokémon like Charizard or Mewtwo. They are powerful and could be leaders in the rebellion.
