In some fanfictions, it could be an original character created by the author. Maybe a witch who was the result of an affair that his father had before he married his mother. However, this is completely against the canon of the original books, but in the world of fanfiction, anything is possible.
There could be various storylines involving Heather as an older sister in Harry Potter fanfiction. Maybe she's a Gryffindor like Harry and helps him out in his adventures, or she could be a Slytherin with her own complex motives.
In such fanfiction, it could lead to a whole new dynamic within the wizarding world. Maybe she'd have her own unique powers or play a crucial role in Harry's adventures.
Yes, there might be. The 'Supernatural' world of Sam and Dean and the 'Harry Potter' universe are both very popular, and fanfiction often likes to cross over different fandoms in creative ways. Some fans might have come up with the idea of making Harry Potter be related to Sam and Dean as their sister in a fan - created story.
One possible reason could be jealousy. Maybe the sister is getting more attention from their parents or at Hogwarts. For example, if she is a star student and Harry feels overshadowed.
The sister's character could be developed as a strong - willed individual. For example, if she was raised in a difficult situation, like in an orphanage in the Muggle world, she could have a tough exterior but a kind heart. She might be initially distrustful of the wizarding world when she discovers it, but as she learns more about her family and the fight against Voldemort, she becomes more open - minded and determined to help.
In many 'Harry Potter sister fanfic' stories, the sister's character is developed through her relationships. She could have a complex relationship with Harry, maybe starting off as jealous of his fame but then growing to support him. Or she might form a really close bond with Hermione, learning from her and becoming a strong female character in her own right. Her character also develops as she faces challenges in the wizarding world, like dealing with discrimination because she's a Potter. These experiences shape her into a more confident and powerful witch.
The twins themselves are often great characters in these fanfics. Their mischievous nature and loyalty to their sister add a lot of fun and heart to the story. The sister, of course, is a central character with her own unique personality and abilities.
One popular 'Harry Potter sister fanfic' is 'The Lost Potter Sister'. It often features a long - lost sister of Harry Potter who discovers her true identity and her connection to the wizarding world. Another one could be 'Potter's Hidden Sister', where the sister has unique magical abilities that set her apart from the other characters in the Harry Potter universe.
Well, it could be that the sister was kidnapped by dark wizards when she was a baby. Years later, Harry discovers some mysterious clues that lead him to believe she might still be alive. He then embarks on a dangerous journey to find her, facing many magical obstacles along the way.
