Well, it could be about a lot of things. It might be a story that focuses on the relationship between Caius and his original character (OC) mate. Maybe it's about their adventures together, or how they met and fell in love in the world of fanfiction. It could also involve some sort of conflict they have to face as a couple, like dealing with other characters who oppose their relationship.
Power dynamics is another theme. Caius has a certain power, and the OC may or may not have their own powers. The fanfictions explore how these power levels interact and how they influence the relationship, whether it's through protection or a power struggle.
You could try searching on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just type in 'caius' mate oc fanfiction' in the search bar and see what comes up.
One great Caius Mate OC Fanfiction is 'Caius' Unforeseen Love'. It has a really interesting plot where the original character has a unique connection with Caius. The story is well - written, with great character development for both the OC and Caius.
There's a lesser - known one called 'Fem Harry and Caius: A New Beginning'. It starts off with a very unique take on how fem Harry and Caius meet. Their relationship progresses slowly, which is nice as it allows the reader to really understand the connection between them. The story also has some great side characters that enhance the overall plot.
Many of these fanfictions explore the theme of identity. Harry has his own identity as a wizard, and Caius has his as a vampire. When they become mates, they have to reconcile their identities and find a new combined identity. This exploration of identity makes the stories really interesting.
One common theme is the struggle against the odds. Since Bella and Caius are from different 'worlds' in a sense, they often have to face opposition from other vampires or even Bella's human friends. Another theme is the discovery of a deep, new connection. It's about how they come to realize their bond as mates.
Love triangles are a big part of these fanfictions. Bella is in a unique position with Carlisle and Caius. There's also the theme of self - discovery. As Bella navigates this new relationship, she discovers new sides of herself. And the theme of family is there too, as Carlisle has his own family and Caius has his own group, and Bella has to find her place within these complex family structures.
One popular 'bella is carlisle and caius mate fanfiction' is 'Twilight Reimagined'. It offers a unique take on the relationships, with interesting character developments.
I really like 'Harry and Caius: Unlikely Mates'. It delves deep into their personalities. Harry's courage combined with Caius' old - world charm makes for a great read. It shows how they overcome differences and form a bond.
