Well, in fanfiction, it can be made to work. Imagine Bella Swan's world of vampires and werewolves colliding with Michael Myers' world. Bella, being a strong - willed character, might initially be repelled by Michael Myers but then find herself drawn to him in a strange way. The plot could revolve around her trying to figure out if there is a way to stop his killing spree without having to destroy him. She could use her knowledge of the supernatural from her own story to try and find a solution, all while being in a very dangerous and unpredictable relationship with him.
One major challenge would be their completely different natures. Bella is a relatively normal human turned vampire - adjacent being with a sense of morality. Michael Myers is a pure - bred killer. Their values are so different that it would be hard for them to co - exist. Another challenge would be the reaction of the other characters in their respective universes. The Cullens from Twilight would surely oppose Bella's relationship with such a malevolent figure, and the people in the Halloween universe would be horrified.
Obviously, Bella Swan is one of the main characters. And the Creeper Mates, though it's not clear exactly who they are as individuals yet. They are likely to be a group or species that Bella interacts with in a significant way.
Yes, there are some. You can start by looking on fanfiction websites like Archive of Our Own. There are often unique takes on this pairing, exploring their relationship in different scenarios within the Twilight universe.
One common theme is the clash of different vampire cultures. Godric has his own set of values from the True Blood universe, and Bella has her experiences with the Twilight vampires. Another theme could be the power dynamic, as Godric is an ancient vampire and Bella is a young, newly turned vampire in some versions. Also, love against all odds is often explored.
In this fanfiction, it could be that the god has been observing Bella Swan from afar. He decides to make himself known to her when she is in a moment of great danger. He saves her and from that moment on, they form a connection. As they become mates, they discover that their union has the power to bring balance to the supernatural world. However, there are forces that oppose their relationship, like other gods or powerful vampires who don't want the status quo to change.
Maybe it's Loki. Loki is known for his mischief and cunning. His complex personality would add a lot of drama to the relationship with Bella. He could bring a whole new level of chaos to the Twilight universe.
Yes, there are quite a few. Some popular ones can be found on fanfiction.net. You can search using the tags 'Bella Swan' and 'Caius Volturi' to narrow down the results. They often explore unique relationships and storylines within the Twilight universe.
One key element is often the exploration of a new relationship dynamic. Since they are not a canon pairing, it's interesting to see how they interact. Another element can be the alteration of the existing story's setting to fit their relationship.
A fanfiction that stands out is 'Parallel Paths'. This story takes Bella Swan and David Mates on parallel but intertwined paths. It starts with them having their own separate lives but then circumstances bring them together in a very unexpected way. The author does a great job of building their relationship gradually. There are also elements of mystery and adventure in it which add to the overall appeal.
