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.
Maybe she's more curious than Vegeta. In fanfiction, she might be the one who is always eager to learn about new planets and cultures. For example, when she arrives on Earth, she's not just there to fight but also to understand how Earthlings live. This makes her a more well - rounded character compared to the battle - focused Saiyans we usually see.
One great fanfiction could be where Vegeta's sister is introduced into the Saiyan saga. She might be a powerful Saiyan herself, trained alongside Vegeta and Nappa. In this fanfic, she could have a unique power that sets her apart, like the ability to control time on a small scale during battles.
The plot could start with Vegeta's sister being sent on a mission to Earth. Goku, being the protector of Earth, initially sees her as a threat. But as they interact more, they realize they have a lot in common. They start to explore their feelings for each other secretly. However, Vegeta discovers their relationship and is furious. He challenges Goku to a fight, thinking Goku has betrayed him. In the end, Goku and Vegeta's sister have to prove to Vegeta that their love is real and that it won't harm their relationship as comrades.
It could be about Tenten's sister's adventures in the ninja world. Maybe she discovers a new jutsu or goes on a mission with Tenten and their friends.
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.
Harry would probably be more aggressive in his personality. Vegeta's Saiyan nature is often associated with a certain level of aggression and competitiveness. So, Harry might show these traits more, not shying away from a fight and always striving to be the best in any magical situation.
Well, one possible plot could be that Thor and Loki's little sister has some special powers that are a mix of their own. She might be caught in the middle of their feuds, trying to bring peace between them. For example, she could use her powers to stop Loki from his mischievous plans that would anger Thor, while also making Thor understand Loki's motives better.
Another possibility is that the fanfiction is set in an alternate universe. In this universe, the little sister has some special powers related to the Duel Monsters world that no one else has. She uses these powers to help Jaden and his friends save the world from an evil force that wants to misuse the power of the Duel Monsters cards. This could involve a lot of action - filled duels and exciting adventures.
Perhaps the fanfiction could focus on the little sister's own journey of self - discovery. Growing up in the shadow of her two powerful brothers, she might strive to find her own identity and power. She could train secretly and then surprise everyone with her newfound abilities. And in the process, Sasuke and Itachi might have to deal with their own feelings about their sister growing up and becoming independent.
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.
She could have the power of super - speed. Just like her father, she has trained hard and developed the ability to move at incredible speeds. This would make her a formidable opponent in battle as she can quickly dodge attacks and launch counter - attacks.
