Another possible main character could be a rival or a competitor. If the sister is into music or some other field, there could be someone who is constantly trying to outdo her. This person could create conflict in the story, making the sister work harder to prove herself. It could also lead to some interesting character development as she learns to deal with jealousy and competition.
Jungkook himself would definitely be a major character. His presence would shape a lot of the story, whether it's through his influence on his sister or their interactions. Their parents could also be important characters. They might play a role in how the sister is raised and how she views her relationship with Jungkook. For example, if they are very strict, it could add a different dynamic to the story.
Her friends could be main characters too. They could be from different backgrounds, some who are fans of Jungkook and some who have no idea who he is. Their reactions to her being Jungkook's sister would add interesting twists. And also, other members of BTS could be in the story. They could act as mentors or just friends to the sister, like giving her tips on fashion or how to handle the media.
There could be some new characters introduced, like a young apprentice from another candy factory who is initially a rival but later becomes a friend. And of course, the customers or kids who visit the factory could also be main characters. They might interact with Willy Wonka's daughter in different ways, for example, a group of kids who get lost in the factory and she has to help them find their way out while also showing them the coolest parts of the factory.
Rock Lee could be one of the main characters. He's Tenten's friend, and he might interact with the little sister, teaching her some of his unique ninja philosophies or training techniques.
Well, it could be about her growing up in the shadow of her famous brother. Maybe she's trying to find her own identity and talents, different from Jungkook's. She might face challenges like dealing with over - protective family members who are used to taking care of a superstar. And she could also have her own group of friends who don't really care that she's related to Jungkook at first, but then start to notice the differences in her life because of it.
Danzo could be a main antagonist. He might see Orochimaru's interest in Naruto as a threat to his own plans for Konoha. He could try to eliminate Naruto or use him as a pawn against Orochimaru, all while hiding his true intentions from the rest of the village.
His friends like Annabeth would surely be main characters. She is smart and resourceful, so she would be leading the search for Percy. Grover could also be a major character. He has a strong sense of loyalty and his connection to nature could be useful in tracking Percy down.
There could be a wise old man who acts as a guide for the girl. He might have been in the puzzle world for a long time and knows many of its secrets. He gives the girl hints on how to solve the more difficult puzzles.
There could be a mysterious old neighbor. This neighbor might have some knowledge about magic or strange phenomena. When the little sister shrinks, the neighbor could offer some clues or tools to help her return to her normal size. Maybe the neighbor has had a similar experience in the past and can guide the little sister through her ordeal.
The parents would be important characters. They could have different reactions. Maybe the father is more accepting and tries to teach the giantess little sister how to use her new power for good, while the mother is initially worried about how society will view their daughter. Their relationship with the little sister and how they deal with the situation can be a big part of the story.
The sender of the howler could also be a main character, even if they are initially anonymous. As the story unfolds, their identity and motives become a central part of the plot. They could be a rival, a teacher, or someone with a grudge against Molly.
Superman could also be a main character. He might be the one to first discover the oc after their rebirth. Superman's moral compass would lead him to either protect the oc or keep an eye on them depending on how the oc behaves. And his super strength would be a factor in any interactions with the oc.
