harry potter is sam and dean's sister fanfiction

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 plot could be that Harry discovers her relation to Sam and Dean early on. She then tries to balance her wizarding education at Hogwarts with the hunting life of her brothers. Maybe she uses her magic to fight off the same demons that Sam and Dean are hunting, but in a different, more magical way.

The main characters are Harry, who is the focus as Sam and Dean's sister. Sam, who is good at research and understanding the deeper aspects of the supernatural. And Dean, who is more hands - on and ready to fight. Their different personalities and how they interact with Harry form the core of the story in this fanfiction.

One possible plotline could be Harry going on hunts with Sam and Dean. She might use her own unique skills, perhaps some magic - like in the Harry Potter world - to help them out in a way that surprises the brothers. Another could be her trying to fit into their world of hunting while also dealing with the typical sibling rivalries and protectiveness.

There's a fanfic called 'Sister's Bond'. In this story, the sister is brought into their lives in a rather mysterious way. It shows how she struggles to adapt to the life of hunting monsters while also trying to understand her new - found brothers. It's full of action and some really heartfelt moments between the siblings.

In a fanfiction, their sister could be a prophet. She starts having visions that lead the boys to new cases. But there are forces that want to use her for their own gain. Sam and Dean would have to fight not only the regular demons and ghosts but also those who are after their sister.

Well, it's possible that such a fanfiction exists. However, this would be a very strange crossover considering that 'Dean and Sam' are from 'Supernatural' and 'Harry' is from the 'Harry Potter' series. It might be a very niche or even a dark and edgy take on combining these two universes. But again, without a proper search on the relevant fanfiction platforms, it's difficult to say for sure.

She could be a nephilim, half - angel and half - human. This would put her in great danger as both angels and demons would be after her. Sam and Dean would have to constantly protect her and figure out a way to keep her powers in check.

The little sister herself can be a great character. She often brings a fresh perspective to Sam and Dean's world. She might be brave but also have a vulnerability that makes her relatable. For example, she could be hesitant about the hunting life at first but then grow into a strong fighter.

One way it could work is by having Hermione's magical abilities blend with the hunting skills of Sam and Dean. For example, she could use spells to help them in their battles against supernatural beings. Maybe she could create protective charms around their hideouts or use her knowledge of potions to create antidotes for the various toxins they encounter. Also, her intelligence and quick - thinking would be an asset during their investigations, just like how she solves mysteries in the wizarding world.
