The theme of sacrifice is also quite prevalent. For example, they might sacrifice their own desires or opportunities for the sake of their relationship. Also, the theme of family acceptance. Sometimes their relationship is not initially accepted by their families, and they have to work through that.
Another plot could be that they are on opposite sides of a conflict initially. But as they realize they are mates, they have to find a way to reconcile their differences and work together. This could involve a lot of internal struggle for both of them as they deal with loyalty to their respective sides and their new - found bond.
Well, in such a fanfiction, Bella and Marcus are usually depicted as mates, which often means they have a special, deep connection. It could involve a lot of romantic and emotional elements. Maybe they go through various adventures together, facing challenges that test their relationship. It might also explore their individual personalities and how they complement each other.
I've also come across 'Marcus & Bella: Mates for Life'. This one is interesting because it not only focuses on their romantic relationship but also on how they grow as individuals within the context of being mates. It shows their development from the moment they realize they are mates to building a life together.
First, do some research on the characters. Know their personalities, powers and backstories from the original source material. For Bella, her tenacity and self - sacrifice are important traits. Aro is power - hungry, Marcus is more introspective, and Caius is hot - tempered. Start with a strong concept, like Bella being a bridge between different vampire factions and the Volturi. Then, build a plot around how their relationships as mates would develop, including any conflicts that might arise due to their different natures.
One idea could be a story where Bella is somehow connected to all three - Aro, Marcus and Caius. Maybe she has a special power that intrigues them all. For example, her ability to resist mental powers in the Twilight universe could be a factor. She could be a key to some sort of vampire - related mystery that they are all trying to solve.
One key element is the unique relationship dynamics. Bella's relationships with Marcus and Alistair are different from the normal vampire - human relationships. It's often about exploring new kinds of love and loyalty.
One popular 'Bella Swan Marcus and Alistair mates fanfiction' is 'The Unlikely Bond'. It explores the unique relationships that form between them in an interesting way.
In some fanfictions, Bella and Emmett might be considered true mates because of their shared experiences within the Twilight universe's unique supernatural context. For example, they both are part of the Cullen family, which could lead to a deeper connection in the eyes of some fanfiction writers. Also, their personalities could be seen as complementary, with Emmett's boldness and Bella's determination.
Yes, there are quite a few. You can check out fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'bella and demetri true mates' on their search bars and you'll find a variety of stories with different plotlines and writing styles.
