What could be a good plot for a Harry has a sister Chloe fanfiction?

Chloe's character can be developed by giving her a flaw. Let's say she is overly curious and sometimes gets into trouble because of it. One time she might open a forbidden book in the library without realizing the danger, and this leads to a series of events that teach her to be more cautious while still maintaining her curious nature. As she faces the consequences of her actions, she becomes more mature and well - rounded.

The plot might revolve around the older sister being a part of a prophecy too. Just like Harry, she has a special destiny. But instead of being in the spotlight like Harry, she works behind the scenes to ensure Harry's success in the fight against Voldemort. She could be the one who finds out about Horcruxes first and guides Harry in that direction, all while dealing with her own challenges at Hogwarts, like trying to keep her identity as Harry's sister a secret from the wrong people.

Perhaps they go on an adventure to find a lost family heirloom. Chloe might use her unique skills, like being really good at deciphering ancient runes, and Harry uses his bravery. They travel to different magical places, like a forgotten castle where the heirloom is hidden. And they have to outwit various magical traps.

Perhaps the sister gets kidnapped by an enemy of Percy's. Percy then has to embark on a dangerous quest to rescue her. Along the way, he discovers more about his sister's true nature and their family's past that was previously unknown to him. This could involve meeting old friends and making new allies.

She could be a half - blood like Harry. Maybe her mother was a muggle - born witch and her father was a pure - blood wizard. This mixed heritage could give her a unique perspective on the wizarding world's issues regarding blood purity.

Well, perhaps the older sister could be a powerful witch. She might protect Harry from the Dursleys' mistreatment in a more forceful way than in the original story. For example, she could use magic to make sure Harry has enough food and a proper room.

One possible plot could be that Naruto's little sister is also a ninja in training. She might struggle with the same kind of ostracism Naruto faced because of the Nine - Tails inside him. However, she could also be a source of great support for Naruto, helping him through his toughest times and together they could train to become stronger. Maybe she has a unique ninja ability that even Naruto is in awe of.

Well, perhaps the story could be about Naruto finding out he has a sister who was hidden away for her own safety. Maybe she has some unique powers that the villains are after, and Naruto has to protect her while also learning about his family's past.

One possible plot could be that Draco's older sister, let's call her Astoria for example, starts to develop feelings for Harry while trying to bridge the gap between the Slytherin and Gryffindor houses. She might see the good in Harry that Draco refuses to acknowledge at first. This could lead to a series of events where she has to choose between her family's traditional views and her new - found respect and love for Harry.

The fanfiction could also be about the challenges Chloe faces during her pregnancy. For example, she might have health problems during the pregnancy. She could also face social issues, like dealing with people who judge her for being pregnant at a certain age or in a certain situation. The story could show how she overcomes these difficulties and grows as a person.
