There could be a female werewolf character who falls in love with one of the Supernatural characters. This would add a romantic sub - plot to the fanfiction and also create a lot of drama as they try to navigate their different worlds and the prejudices that come with being a werewolf and a hunter.
A popular character could be a half - werewolf, half - hunter. This character would be constantly torn between their two natures, and in a crossover, they could be a bridge between the werewolf community and the hunters in Supernatural.
Another character might be an alpha werewolf who decides to make a deal with the Winchesters. This alpha could have its own motives, like protecting its pack from a greater threat that the Winchesters are also after.
One idea could be a story where a werewolf from the werewolf lore gets caught in the middle of a Supernatural's Winchester brothers' hunt. Maybe the werewolf has information about a powerful demon they are chasing.
Well, obviously Bella herself is a central character. Jacob is also very popular as he is a werewolf in the original story and often has a complex relationship with Bella in the fanfiction. Then there are the other members of the wolf pack like Sam and Seth. They can play important roles in Bella's new werewolf life, either as mentors or as friends who help her adapt to her new identity.
One popular supernatural crossover fanfiction involves 'Supernatural' and 'Doctor Who'. In this type of story, the Winchester brothers might team up with the Doctor to fight against a common supernatural threat that spans across different universes. It combines the dark, monster - hunting world of 'Supernatural' with the time - and - space - traveling adventures of 'Doctor Who'.
One popular character could be the girl who befriends the werewolf boy. She often serves as the connection between the werewolf boy and the human world. Another might be the werewolf boy's mentor or an older werewolf who teaches him about his heritage. And sometimes, there's a villain, like a hunter who is after the werewolf boy, which adds conflict to the story.
Luna Lovegood is often reimagined as a female werewolf in some fanfictions. Her unique personality and the way she views the wizarding world adds an interesting twist when she is given the werewolf trait. Writers explore how she copes with her new identity and how it affects her relationships with other characters like Harry and Hermione.
Leah Clearwater is a very popular one. In the original Twilight series, she's a complex and interesting character, and in fanfictions, she often takes on even more central roles. Another could be a new, original female werewolf character created by the fanfiction authors. These original characters can bring new storylines and relationships to the Twilight universe that involve werewolves.
Lady Ashbury from Vampyr could also be a great character for crossovers. She is powerful and mysterious. In a crossover with Castlevania, she could either be a powerful force against Dracula or perhaps have some hidden connection to him that could be explored. Her knowledge of the vampire world in Vampyr could bring new perspectives to the Castlevania universe.
Some fanfictions might pair Castiel and Cisco Ramon. Castiel's otherworldly nature and Cisco's scientific mind could lead to some really interesting interactions. For example, Cisco could be fascinated by Castiel's angelic powers and try to find a scientific explanation for them, while Castiel could be intrigued by Cisco's tech - savvy ways.
One great 'Twilight werewolf crossover fanfiction' is 'Twilight Meets the Pack from Another World'. It combines the allure of the Twilight werewolves with an exciting new world concept. The story delves into how the Twilight werewolves interact with characters from a different universe where werewolves have different powers and social structures. It's really interesting to see how the Twilight characters adapt to this new situation.
One common theme is the struggle between different species. For example, in a werewolf - vampire crossover, there's often a fight for territory or power. Another theme is love across species. Werewolves might fall in love with humans or other supernatural beings, which creates a lot of drama.
