A frequent theme is the exploration of identity. The OC may have to re - evaluate who she is when she gets involved with Damon. For example, she might become part of the supernatural community, which changes her self - perception. Also, loyalty is a big theme. Damon and the OC have to show loyalty to each other, especially when facing external pressures. For instance, when other vampires or supernaturals might not approve of their relationship. And of course, there's the theme of family. They create a new family unit through their marriage, which includes not only themselves but also the friends and allies they gather along the way.
One common theme is love triangles. Since it involves Damon, Stefan and an OC, often there's a complex love situation. For example, the OC might be attracted to both brothers in different ways.
Love and passion are very common themes. Since it's often about Damon, there's usually a strong sense of attraction and a complex relationship. For example, in many of these fanfictions, the OC might be initially hesitant about getting involved with Damon because of his reputation, but then they can't resist the pull towards each other.
A common theme is the forbidden love aspect. Since Damon has his own complex history and often behaves in a morally ambiguous way, a relationship with an OC is often portrayed as something that goes against the norm or is difficult to accept. Another theme is redemption. The OC might be the catalyst for Damon to seek some form of redemption in his life.
One common theme is the power struggle. Damon's possessiveness often leads to a tug - of - war between his desires and the OC's independence. Another theme is the idea of protection. His possessive nature can be seen as a form of protecting the OC from other threats in the supernatural world.
One common theme is redemption. Damon has a dark past, and in many OC fanfictions, his love for the OC character leads him to seek redemption. For example, he might try to make up for his past wrongdoings to be worthy of the OC's love. Another theme is the power of love to change. The OC's love can make Damon more empathetic and less ruthless. Also, the theme of forbidden love often comes up. Since Damon is a vampire and there are usually some rules or conflicts in the supernatural world, their love is often seen as forbidden, which adds to the allure and drama of the story.
One possible story could be that Damon, a mysterious and charming character, meets an ordinary girl (the OC). They initially clash but gradually fall in love. When they get married, their wedding is a mix of the supernatural world Damon is from and the normal world of the OC. Their friends and family, both from different sides, come together. Damon vows to protect the OC from all the dangers that lurk in his world, and they start a new life full of adventures and love.
Well, a popular trope is the 'domestic bliss vs. supernatural chaos' one. They might be happily married at home, but then have to deal with all the craziness of the supernatural world outside. Also, the 'jealousy' trope can come into play, either from other characters being jealous of their relationship or Klaus and Damon being jealous of each other's past relationships.
One common theme is love and romance. Many fanfictions revolve around a female character falling in love with Damon, despite his flaws. Another theme is redemption. The female character might be the catalyst for Damon to become a better person. And there's also the theme of adventure, where they go on some sort of journey together.
Another theme is the power of friendship turning into love. They start as friends or reluctant allies and then slowly develop deeper feelings. This is seen in a lot of fanfics where they initially work together against a common foe and then realize they have more than just a friendly connection.
A major theme is the clash of different worlds. Bella's more human - centered world in Twilight and Damon's vampire - filled world in The Vampire Diaries. Their relationship has to navigate this divide. Also, power dynamics play a role. Damon is a powerful vampire, and Bella is often portrayed as having a certain power over him, like with her love, which is another common theme.
