Power struggles are another big theme. When characters from different supernatural universes meet in fanfiction, they often compete for power. For instance, if 'The Vampire Diaries' characters cross over with those from 'Supernatural', the vampires might battle the hunters for control over a certain territory or a powerful magical object. This creates a lot of action and tension in the stories.
Love triangles are common. Since 'The Vampire Diaries' already has a lot of love triangle drama, when it's crossed over with other shows, this theme often continues. For example, if crossed with 'Twilight', you might see Bella, Edward, and Damon in a complex love situation.
Redemption is also a frequent theme. Maybe a character from one universe who has done bad things in their own story gets a chance to redeem themselves in the crossover. Like a vampire from 'The Vampire Diaries' who has killed a lot of people, but in the crossover with a more morally upright universe like 'Buffy the Vampire Slayer', they try to change their ways and fight on the side of good.
Well, a frequent theme is the clash of different cultures. In a Vampire Diaries and Harry Potter crossover, you have the magical culture of Hogwarts clashing with the vampire - based culture of Mystic Falls. This can lead to misunderstandings and conflicts that drive the story forward. Also, survival is a big theme. In many crossovers, the characters have to find a way to survive in a new and more dangerous world created by the crossover. For instance, in a Vampire Diaries and Buffy the Vampire Slayer crossover, the vampires from Vampire Diaries might have to adapt to the slayer - filled world of Buffy or face being staked.
The theme of redemption also pops up. Characters who have done wrong in their own series might find a chance to redeem themselves in the fanfiction world. For instance, a villain from 'Bleach' could end up in the 'The Vampire Diaries' universe and try to change their ways by helping the good guys against the vampires or other threats in that world.
One common trope is the 'fish - out - of - water' situation. For example, when the characters from Supernatural first arrive in Mystic Falls, they are confused by the different rules of the vampire society there compared to the monsters they usually hunt. Another trope is the 'power - struggle'. This could be between the powerful vampires like the Originals in Vampire Diaries and the angels or demons from Supernatural. They often have to compete or cooperate depending on the situation in the fanfic.
Themes usually include the struggle with identity. In a world full of supernatural beings, a pregnancy can make a character question who they are and what they want to pass on to their child. Also, there's often a theme of sacrifice. The mother or father might have to sacrifice their own desires or safety for the sake of the baby. It's like in some fanfictions where a character gives up their vampire powers to ensure a normal life for their unborn child.
One common theme is Kol's struggle for acceptance. Since he's often seen as the 'bad boy' in the Vampire Diaries, many fanfictions explore his desire to be understood and accepted by others. Another theme is his relationships, whether it's romantic relationships or his complex family dynamics. For example, his interactions with his siblings are often a big part of the stories.
One common theme is love and relationships. OCs often find themselves falling in love with the main characters from the show or other OCs. It adds a new layer of romantic drama to the already complex world of the Vampire Diaries.
Love and family are also prevalent themes. The mpreg situation usually brings the characters closer together in unexpected ways, forming new family units or strengthening existing ones. For example, a character who was previously a loner might find a new sense of belonging because of the pregnancy. It's also about how love can overcome the challenges presented by this unique situation.
One common theme is friendship. Stiles often forms deep and unexpected friendships with vampire characters. Another theme is the struggle between good and evil, as Stiles tries to navigate the complex moral landscape of the vampire world. Also, self - discovery is a big part. Stiles usually discovers new aspects of himself while interacting with vampires.
The theme of self - discovery is also quite prevalent. In the Vampire Diaries universe, both Jeremy and Tyler are constantly evolving. In Jyler fanfiction, their relationship can be a catalyst for their individual self - discovery. They might learn new things about themselves through their interactions, like Tyler learning to be more open and Jeremy becoming more confident. This exploration of their characters within the context of their relationship makes for some really engaging fanfiction stories.
One common theme is love against all odds. Since it's 'slash' fanfiction, it often features relationships that might not be considered traditional in the original show. Another theme is the struggle between good and evil within the characters, just like in the show but with a different spin because of the new relationships.
