Well, first of all, many writers create a backstory for the twin sister. This could involve her early childhood, how she discovered her quirk, and how it affected her relationship with Izuku and their family. Her character is also developed through her interactions with other characters in the My Hero Academia universe. If she has a mentor, that relationship can be a big part of her growth. Additionally, her values and beliefs play a role. For instance, she might have a strong sense of justice that drives her actions, or she could be more focused on helping the underdog. This all combines to form a well - rounded character.

Additionally, 'Twin Heroes' is a story that portrays their shared dreams and how they strive to achieve them together, with some great plot twists along the way.
You can start by giving her a distinct personality. If Twilight is studious and a bit reserved, make the sister more carefree and impulsive.

Also, give her some unique hobbies or interests, like she's really into ancient runes or potion - making. This will make her a more well - rounded character.
First, give her a distinct personality. If Naruto is all about determination and Sasuke is brooding, she could be the calm and wise one. Then, give her a backstory. Maybe she was separated from Sasuke at a young age and grew up in a different part of the ninja world. This would shape her view of things. Another way is to show her relationships. For example, how she interacts with Naruto's friends like Sakura and Kakashi. This will help to flesh out her character more.
They could both develop their teamwork skills. In fanfiction, they might be put in various dangerous situations that require them to rely on each other. Izuku learns to better incorporate Melissa's support items into his fighting style, and Melissa learns how to adjust her items based on Izuku's needs and fighting style at the moment. This back - and - forth development makes their characters more well - rounded.
For Tinkerbell, emphasize her kind - hearted and curious nature. She should be determined to save her sister. As for the vampire twin sister, give her a conflicted personality. She's a vampire but still has some of the fairy traits like a love for nature, but it's overshadowed by her new thirst. You can show her internal struggle through her actions and dialogues.
At first, the relationship might be strained. Naruto could be jealous of his sister's favored status. However, as the story progresses, his sister might start to see the injustice Naruto faces and try to bridge the gap. They could gradually develop a more understanding and loving relationship.
In these fanfictions, Izuku often develops more confidence in his relationships. For example, he may start off shy around the girls in his harem but gradually become more assertive. This is because the support and love from his harem give him an extra boost.
One popular fanfiction with this concept might be 'Twin Flames' (this is a made - up title for example). In it, Izuku being Todoroki's twin sister adds an interesting dynamic to the story. It often explores how their different upbringings, with Izuku in a more normal environment initially compared to Todoroki, shape their personalities and relationships within the UA world.
