Obviously, Dean and Sam are main characters. They are the protective older brothers. And then there's the baby sister, who is likely a central figure as well, with her own personality and role in the fanfiction. There might also be other recurring characters from the 'Supernatural' universe like Castiel who could play important parts in the story.
Dean and Sam Winchester are the mainstay characters as they are the well - known figures from 'Supernatural'. Their baby sister is a main character too. She might be written as someone with hidden depths and abilities. Additionally, characters such as Crowley could potentially be involved in the fanfiction, either as an antagonist or an unexpected ally in relation to the baby sister's story.
One interesting storyline could be the baby sister having special powers that she has to learn to control. Maybe she can communicate with spirits in a unique way, different from Sam and Dean, which adds a new dynamic to their hunting adventures.
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.
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.
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.
The main reason is that it adds a new dynamic to the existing relationship between Sam and Dean. A sister character can bring in a whole new set of emotions and storylines. For example, it could be about protecting their sister, or the sister protecting them in a different way than they are used to.
It could be demons. Demons are often the main antagonists in the Supernatural universe, and they might target Bella because she is related to the Winchesters. They could try to use her as a bargaining chip or a way to get to the brothers.
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.
Some fanfictions focus on the baby sister's relationship with other characters like Castiel. Maybe she has a special bond with him, and they work together to protect Sam and Dean. This kind of story explores different character interactions and can be really engaging.
