There's a fanfiction that focuses on the sister's unique abilities and how she uses them to protect her star brother. In this story, their bond is tested by various challenges in the Lost Boys' universe. It's a really engaging read as it explores their characters more deeply.
One common theme is family loyalty. Despite the strange and often dangerous world of the Lost Boys, the bond between the star and his sister remains strong. Another theme is self - discovery. The sister often has to figure out who she is in this new and wild environment.
There could be a fanfiction where Leo's twin sister is the smarter one and she has to protect Leo when he gets into trouble. For example, she uses her intelligence to outwit a villain who is after them in the lab.
She could also have a different view of the world compared to the Lost Boys. Since she has a connection to the stars, she might see things from a more celestial perspective. This could lead to interesting conflicts and resolutions within the fanfiction. For example, she might think that certain actions the Lost Boys take are wrong according to the stars' 'code' or something similar.
In this type of fanfiction, the star sister might be an outcast like the Lost Boys. They could bond over their shared sense of not belonging. The story could explore how they come together and form a unique family. The Lost Boys might protect the star sister from those who want to use her powers for evil, and in return, she could use her star - related abilities to keep them safe from the sun or other threats.

One interesting fanfiction could be where Hope's twin sister has a different power set. For example, while Hope has her typical witch/vampire/werewolf powers, the sister could have the power to manipulate time.

Maybe she goes back to when Klaus was first turned into a vampire and tries to prevent it, which would change the entire course of the family's future.

There could be a fanfiction where Naruto's twin sister, Lemon, has a different path than Naruto. Maybe she is more interested in the medical side of ninja arts rather than combat. This would lead to her interacting with different characters like Tsunade.

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.
