Create characters with moral ambiguity. In a Magical Girl Apocalypse, the lines between good and evil can be blurred. A character might start off doing bad things to survive but gradually realizes the importance of helping others. Also, consider adding characters from different species or dimensions that have been affected by the apocalypse. This can add more diversity to your fanfic.
You can start by mixing different magical girl archetypes. For instance, combine the shy, bookish type with a more aggressive, warrior - like personality. Another way is to give them unusual powers related to the apocalyptic setting. Maybe one character can control the rubble and debris left from destroyed cities.
You can give her unique physical features like a special pattern on her scales or different colored eyes. For example, she could have eyes that change color depending on her mood.
You can give them distinct physical features. For example, one monster girl could have wings like a butterfly and be able to pollinate the plants faster. Another could have tentacles instead of arms, which she uses to gather eggs from the hens without breaking them. Also, give them different personalities. One might be super shy and only come out at night to work, while another is really outgoing and loves to sing while she tends to the fields.
Create backstories that involve lemons. For instance, a character was born near a lemon tree that was blessed by a powerful fairy. This made her have special powers related to lemons. She could be a monster girl with fairy powers who uses lemons to make potions to help other monster girls. Her appearance could also be influenced by the lemon tree, like having lemon - colored hair or eyes.
Think about the different cultures in Alola. You could create a character who is a descendant of an ancient Alola tribe and has special knowledge about Pokemon passed down through generations. This would make them unique and add an interesting element to the story.
To create unique characters, start with their backstory. For example, a character could have grown up in a hidden part of the 'game of fate' world, away from the main action, which gives them a different perspective. Give them a distinct personality trait, like being overly superstitious in a world full of calculated risks. Their appearance can also be unique, perhaps having a rare mark on their body that is related to an old legend in the game's lore.
Combine different traits. Maybe a character is both extremely powerful in magic but also has a crippling fear of heights. This kind of contradiction can make a character more complex and unique. They could be the most powerful mage in a battle on the ground but completely useless when they have to fly on a magical broom to reach a high - up tower.
Give them unique appearances. Maybe a trainer has a distinct style of clothing inspired by a certain type of Pokemon. This can also tie into their personality. For instance, a trainer who loves Electric - type Pokemon might have a bright, electrifying color scheme in their clothes. Also, consider their Pokemon teams. A character with a team full of Poison - type Pokemon might be seen as more mysterious or edgy compared to someone with a team of cute Normal - type Pokemon.
You can start by basing them on different aspects of the coral island itself. For example, a character could be inspired by the colorful coral, being very flamboyant and full of life. Or a character could be like the tides, sometimes calm and other times wild and unpredictable.
For her personality, make her super curious. She's always exploring the nooks and crannies of the house she works in, not just because it's her job to clean, but because she's genuinely interested in human things. And she has a sassy side, always making witty remarks when the master is being a bit too bossy.
Look at the existing character traits in the movie and invert them. For example, if most of the characters in Halloween Town love scaring, create a character who is scared of scaring others. This contrast can make for an interesting and unique addition to your fanfic.
