Fanfiction about Harry Potter having younger siblings: What are some interesting storylines?

One popular fanfiction might be where Harry has an older sister who was hidden away to protect her from Voldemort. In this story, she could have been trained in magic secretly and then return to Hogwarts to help Harry in his fight against the Dark Lord.

One interesting storyline could be that Harry discovers his moon powers during a full moon at Hogwarts. Maybe he can communicate with magical creatures that are only active during the full moon. Another could be that his moon powers are linked to a hidden prophecy, and Voldemort wants to steal those powers for himself.

Well, a storyline could revolve around the mystery of her blindness. Maybe it was caused by a dark spell when she was a baby, and as the story progresses, Harry and his friends try to find a way to reverse it. Meanwhile, she is learning to be independent and strong. She could also form a special bond with some magical creatures that are attracted to her unique situation. For instance, a thestral might befriend her because she can sense its presence without seeing it in the normal way.

Perhaps a fanfiction could show Harry's relationship with his professors in a new light. Some professors, like Professor Snape, might initially be unsympathetic, seeing it as a Muggle weakness. But as the story progresses, they could come to understand the gravity of his situation and help him in their own ways. Dumbledore, on the other hand, could use his wisdom to guide Harry in accepting his condition and still being a great wizard.

One possible storyline could be that Harry discovers his angel wings during a dangerous battle at Hogwarts. The wings give him the ability to fly faster and more gracefully than a broomstick, allowing him to outmaneuver the dark forces. He could use them to rescue his friends from precarious situations, like flying them to safety when the castle is under siege.

One possible storyline could be the brother being a Slytherin while James is in Gryffindor, creating a lot of family tension. They could start off at odds but gradually come to understand and support each other. For example, the brother might initially be involved with some not - so - nice Slytherin groups, but through James' influence and some difficult experiences, he realizes the importance of family and loyalty.

Well, in such a fanfiction, the younger siblings could be part of a new generation of Konoha's protectors. They might form a team with Naruto's friends' younger siblings too. This would create a whole new set of adventures. And perhaps, they could help Naruto in his fight against stronger enemies. They could provide support in ways Naruto didn't expect, like using some secret family jutsu.

And there could also be a fanfic where Hermione discovers she has a younger brother who has been held captive by Death Eaters and she embarks on a dangerous mission to rescue him.

A more comical storyline could be Crookshanks accidentally getting into a magical mishap that gives him the ability to talk for a day. He then spends the day criticizing Ron's treatment of him, while also sharing some of the secrets he's learned from prowling around the Gryffindor common room at night. Hermione is both amused and exasperated as she tries to keep Crookshanks out of trouble.
