Well, she could be rebellious. Tired of the family's expectations and the way things are done in the Todoroki household. She might have a fiery side (pun intended) that makes her stand up against the traditional ways. And she could also be very empathetic, having seen the pain in her family members and wanting to heal those wounds. For example, she could be the one to try and reconcile her father and Shoto. Another trait could be that she's extremely creative. Since she has these unique powers, she might use them in ways that are different from the typical hero - like applications. She could create ice - based art or use fire to tell stories through dancing flames.
She could be very reserved, like Shoto. Maybe she's quiet because of the family drama she's witnessed. She might also be highly competitive, constantly trying to prove herself in a family full of strong - willed individuals.
Once upon a time, there was a Todoroki sister OC named Hana. She had the same white and red hair as her brother Shoto. Hana was often in the shadow of her powerful siblings. But she had a unique power of her own - the ability to manipulate ice and fire separately, not just together like Shoto. One day, she decided to prove herself. She entered a hero competition at school. At first, everyone underestimated her. But as the challenges went on, she showed her true strength, impressing everyone with her precise control over her powers.
In this OC fanfiction, Snape's husband could have a strong sense of justice. This would be important as Snape has also been involved in battles between good and evil. He might be creative, coming up with unique solutions to problems that Snape might face. His personality could also be one of perseverance. Given that Snape has a complex and often difficult life, his husband would need to persevere through tough times with him. And he could be a bit of a free spirit, adding some lightness to Snape's rather serious and often dark world.
Perhaps she is very determined. If she decides to break away from her mother's shadow and the world of the Death Eaters, she would need to be. She would face many obstacles, including the wrath of her mother and the other Death Eaters. But her determination could drive her to seek a new life, maybe even one where she helps to reform the wizarding world's view on things like blood purity and the use of dark magic.
She could be rebellious. Tired of her mother's dark ways, she might rebel against the pure - blood supremacist ideology Bellatrix adhered to. For example, she could befriend Muggle - borns openly.
Perhaps she's a bit rebellious. Tired of always following Ezekiel's rules, she might want to explore on her own and prove herself. This could lead to her getting into some dangerous situations, but also show her independence. She could also be resourceful, knowing how to find food and supplies in the most unlikely places.
She could be brooding like Snape. Since she's his niece, she might have inherited that moody and introspective nature. For example, she could often be found alone in the library, lost in her thoughts.
One popular type is the 'Todoroki and the Newcomer' story, where an original character enters U.A. High and forms a special bond with Todoroki. It often involves them going through training together and overcoming challenges. Another could be the 'OC's Hidden Power' fanfic, where the OC has a unique quirk that Todoroki helps them understand and control. And there are also stories about an OC who is from Todoroki's past, like they were childhood friends and are reunited in a surprising way at U.A.
The baby might inherit Sasuke's brooding and determined nature. It could be very focused on achieving its goals, just like Sasuke was on his revenge mission. At the same time, from Sakura, it could get a sense of compassion. So it might be a complex character who is tough - minded but also caring towards others.
Lyra may possess a strong sense of justice, which she gets from Hermione's Gryffindor side. However, she may also have a certain elegance and poise, similar to Draco. In social situations, she could be very observant, a skill she inherits from both parents. She may use this to her advantage, whether it's in the classroom or in dealing with the complex politics of the wizarding world. Also, she might be a bit of a loner at first, trying to figure out her place in a world that doesn't quite understand her unique heritage.
She could be really proud, just like Vegeta. Since they are from the Saiyan race, pride in their power and heritage would be a big part of her personality.
