In Pokemon Sun New Story, it's possible that there will be a group of characters who are part of a Pokemon conservation organization. They could play an important role in the story, perhaps helping the main character understand the importance of protecting Pokemon and their habitats. There could also be some characters related to the lore of the Alola region, like an elder who knows ancient stories about the Pokemon in the area and helps the main character in their journey by sharing this knowledge.
There might be a professor character who gives the main trainer their first Pokemon and provides guidance throughout the story. And of course, there will probably be some rival trainers. These rivals could have different goals and personalities, some might be friendly while others are more competitive.
The main character is the player - controlled trainer. There's also Professor Kukui who is important as he provides guidance. Lillie is another main character. She has her own story arc related to the mysterious Pokemon she's associated with. And then there's Hau, who is like a friendly rival to the player. These characters play crucial roles in driving the story forward in the Pokemon Sun and Moon anime game.
Some of the main characters include Red, the classic Pokemon trainer. He is known for his strong Pikachu. There's also Misty, a skilled water - type Pokemon trainer.
Lillie is also a main character. She has her own story arc, especially regarding her relationship with Pokemon and her growth from being initially afraid of them to becoming more confident. And her family's secrets might also play a role in the fanfic.
I don't know yet as I haven't read it. But typically in a sci - fi novel, there could be a brave explorer, a brilliant scientist, or a strong - willed leader as main characters.
Obviously, Greninja is one of the main characters as the title suggests its return. The trainer who was associated with Greninja before would also be a main character. They are likely to be central to the story's development.
Ash is the central character for sure. Then there could be some new characters created specifically for the fanfiction. They might be the ones who instigate the betrayal. For example, a mysterious trainer who has a grudge against Ash. His friends in the Alola region play a big role too. They are the ones whose reactions to the so - called betrayal by Ash form a major part of the story. Pikachu, as Ash's most loyal pokemon, is also a key character as it has to deal with the situation where Ash is being betrayed.
The new story in Pokemon Ultra Sun can bring a fresh perspective to the Pokemon world. It might introduce new friendships between characters. There could be a new tournament or competition added to the plot. Also, the story may have elements that connect the Alola region more closely to other Pokemon regions, like through some ancient artifacts or a traveling trainer from another place who brings new challenges and knowledge to the Alola region.
In Pokemon Sun New Story, it may introduce new character arcs. For example, a new villain might emerge with a unique plan that threatens the peace of the Alola region. The protagonist would then have to go on a quest to stop this villain, all while evolving their Pokemon and making new friends along the way. There could also be new types of Pokemon contests or challenges specific to this new story.
I'm not sure as it depends on the specific fanfic. It could be a new trainer starting out.
There could also be villains as main characters in some stories. They might be trying to steal powerful Pokemon or disrupt the balance in the Pokemon world. Their actions create the conflict that the other characters have to resolve.
