For Snow White, instead of just being the sweet and gentle character, she could have a hidden feisty side. Maybe she has been suppressing it because of her royal upbringing. When she meets Emma Lemon, Emma's boldness encourages her to show this side more. For Emma, she could start off as a bit of a loner but as she gets closer to Snow White, she learns the value of friendship and becomes more open and caring.
They could start a magical training school together. Snow White has her own knowledge of magic from her long life in the fairy - tale world, and Emma has her unique brand of modern - day magic. By teaching others, they would also be learning from each other. They would have to work together to design the curriculum, deal with difficult students, and face any magical threats that come their way. This would create a partnership that goes beyond just friendship, as they are building something important together and depending on each other's skills and knowledge.
We could also develop their relationship in a unique way. Instead of the typical hero - villain dynamic, they could become mentor - mentee. Ursula, with all her knowledge of magic and the ocean, could teach Ariel things that she wouldn't learn from her own kind. And Ariel could teach Ursula about forgiveness and second chances. This would completely change the way we see both characters and their interactions.
For Emma, you could explore her insecurities more deeply. Maybe she doubts her role as a hero because she's made mistakes in the past. Snow White could help her see that everyone makes mistakes and it's how you grow from them that matters. For Snow White, you could show her dealing with modern - day concepts she doesn't understand, which Emma could introduce to her. This would make her character more complex as she tries to adapt.
Their relationship could develop uniquely if they start sharing a secret hobby. For example, they both discover a love for painting or astronomy. This shared interest would give them something special to bond over, away from the drama of the lying game.
For the white tiger, you can start by giving it a distinct personality. For example, it could be proud but also have a soft side. Show its growth by making it face situations where it has to put aside its pride, like when it needs to ask for help from the lemon. The lemon can be developed as a curious and brave character. It may seem small and insignificant at first, but as the story progresses, it shows great courage in the face of danger.
Their relationship could develop uniquely if Charlie starts teaching Renesmee about human history and culture. Since she has a vampire side, she might view things from a different perspective, and this exchange of ideas could deepen their bond.
One way is to put them in a situation where they have to rely on non - verbal communication. Maybe they are in a place where sound is not possible. They would have to learn to read each other's expressions and body language more deeply. This would force them to understand each other on a different level and strengthen their relationship. Also, they could be given a shared power that they can only use when they are in complete harmony. This would require them to work on their relationship constantly to be able to access this power.
For Hermione, you could develop her character by having her be more conflicted about the use of magic. Meeting Gellert, who has such extreme views on magic and power, could make her question her own Hogwarts - taught values. For Gellert, instead of just being the 'evil' character, show his more human side. Maybe he has regrets deep down. For example, Hermione could find a way to communicate with his past self and see his early dreams that were not so dark.
To develop Roseline uniquely, you could give her an unusual hobby like collecting antique keys. This hobby could tie into the story in some way, like leading to a mystery she and Bella have to solve. For Bella, you could make her really good at parkour, which gives her a different kind of physicality and confidence. When they face challenges, their skills can play important roles.
For Percy, you could explore his insecurities more deeply. Maybe he's worried about living up to his reputation as a hero. With Emma, give her unique traits. For example, she could be really good at deciphering ancient languages. Then, put them in situations where they have to rely on each other. Like when they're trapped in an ancient maze.
