Well, aside from the emperor, there could be rival leaders from other regions or kingdoms who try to oppose him. There may also be some young and upcoming Pokemon trainers within the Johto kingdom who look up to the emperor and strive to be like him, and their journey might be part of the story as well.
There could be trainers who are loyal to the emperor. They might play important roles, like being his advisors or leading his Pokemon army. And of course, there might be some Pokemon that are closely associated with the emperor, such as his personal Pokemon which could be a very powerful and rare one.
The main character is likely to be the emperor himself. He would be at the center of the story, making decisions and ruling the kingdom.
It might be about an emperor in the Johto kingdom in the Pokemon universe. It could involve power struggles, as perhaps other regions or powerful trainers are vying for control of the Johto kingdom. It may also explore the local Pokemon species that are unique to this area and how they interact with the emperor and his subjects.
I think Aqua would be an interesting character to be paired with in Pokemon fanfiction. Given her strong will and combat skills, she could be a great trainer. She might be particularly interested in Water - type Pokemon and train them to be extremely powerful. Roxas could also be a likely character. His connection to Sora and his own unique fighting style could make for an exciting story. He could be on a journey to discover more about himself while also exploring the Pokemon world. And of course, King Mickey. His leadership and magical abilities would make him a formidable ally in the Pokemon world. He could lead a group of trainers and Pokemon against a great threat, like a new type of Heartless - like Pokemon.
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, Nyssa is a main character. She is likely to be the central focus of the story, driving the plot forward with her actions and decisions. Another main character could be her first Pokemon, which she has a special bond with. This Pokemon might be her constant companion throughout her adventures.
There might be other trainers in the fanfiction. They could be friends or rivals to Elaine. A rival trainer could constantly challenge Elaine to battles, pushing her to improve. And her friends could join her on adventures and offer support when she faces difficulties.
Obviously, Sawyer is a main character. But there could also be his Pokemon as important characters. Depending on the story, other trainers he meets during his journey might also be main characters. For example, if it's a story about a big tournament, the opponents he faces could be main characters too.
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.
