Obviously, Hilda is one of the main characters. Since she is the one being hypnotized, the story likely revolves around her experiences and how she copes with the situation.
One interesting aspect could be how Hilda's character is developed in a unique way under hypnosis. Maybe she gains new abilities or perspectives that she didn't have before. For example, she might be able to communicate with Pokemon in a different way, like understanding their deepest emotions and thoughts. This could lead to her forming stronger bonds with her Pokemon and achieving greater feats in battles.
There could also be a mysterious pokemon trainer who has a special ability to hypnotize pokemon. This character might be a bit of an enigma, with motives that are not clear at first. They could be either a villain trying to use hypnosis for their own gain or a misunderstood character who is actually trying to help pokemon in a different way through hypnosis.
Often, the main characters are trainers. Since they are the ones most closely associated with Pokemon, they are likely to be the ones affected by the hypnotic events. For example, a young trainer might be hypnotized by a Pokemon's special ability.
I don't know for sure, but I assume Hilda is one of the main characters. There might be other characters like her friends or family members as well.
The main character is Hilda herself. She is a brave and curious girl who is always exploring the magical world around her. Then there's Twig, her loyal deer - fox friend who accompanies her on her adventures. Another important character is Johanna, Hilda's mother.
Well, there could be an evil scientist in the fanfiction. This scientist might be researching the power of hypnosis on Pokemon trainers and sees Iris as a perfect test subject. They would use their advanced technology and knowledge of Pokemon behavior to hypnotize her. Also, a powerful psychic - type Pokemon that has gone rogue could be an antagonist. It might hypnotize Iris to do its bidding, like stealing other powerful Pokemon or causing chaos in Pokemon battles. And don't forget about a group of treasure hunters who want to use Iris's hypnotized state to find a hidden treasure that only she knows the location of through her adventures.
The main characters are usually the Power Rangers themselves. They are the focus as they are the ones being hypnotized. This includes characters like the Red Ranger, who is often seen as the leader and has to find a way to break the hypnosis not just for himself but for the whole team.
The main characters are clearly Rias and Issei. Rias is often a strong and important character in the series, and Issei is the one who hypnotizes her in this fanfiction.
If the 'hilda doll graphic novel' is about the doll's adventures, then Hilda herself is likely a main character. There might also be other characters like the people who own or interact with the doll. For example, a little girl who takes care of the Hilda doll could be another main character. There could also be some sort of magical or talking animal friends that the doll has in the story.
The main character is Hilda. She is likely the central figure who drives the story forward. And the troll is another main character. It's their interactions and the relationship between Hilda and the troll that might form the core of the story in the graphic novel.
