One idea could be a story where the vampires from 'True Blood' and 'The Vampire Diaries' have to team up to fight a common enemy, like a powerful ancient vampire or a new type of supernatural threat. Another could be a love story between a character from 'True Blood' and one from 'The Vampire Diaries', exploring how their different vampire cultures affect their relationship.
Imagine if Elena Gilbert was somehow connected to an Infinity Stone. This would draw the attention of Thanos, but also the Avengers. The Vampire Diaries characters would have to protect Elena while also dealing with the fact that the Avengers are now in their small town. There could be a lot of mistrust at first, but as they learn more about each other's motives and capabilities, they form an alliance to keep the Infinity Stone out of Thanos' hands.
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.
A popular one is 'A New Alliance'. In this fanfiction, the plot brings together the different supernatural elements from 'The Vampire Diaries' and 'The Originals' in a unique way. The author does a great job of maintaining the personalities of the original characters while also creating new and exciting storylines. It's a must - read for fans of the two shows.
One great 'Vampire Diaries' crossover fanfiction is 'The Vampire Diaries and Supernatural: The Crossover'. It combines the dark, supernatural elements of both shows really well. The characters from each show interact in a believable way, and the plot keeps you hooked from start to finish.
Maybe Caroline. Caroline is strong - willed and has a positive attitude. Hermione, with her determination and intelligence, could bond with Caroline. They could support each other through the different challenges in the 'Vampire Diaries' world, whether it's dealing with vampires or other supernatural creatures. Plus, Caroline's social skills could help Hermione navigate the complex social dynamics of the show's characters.
Klaus Mikaelson is definitely one of the most popular. His complex and often villainous nature in The Originals makes him a fascinating character to bring into the world of The Vampire Diaries. He can stir up all kinds of trouble and create new dynamics among the characters in Mystic Falls.
One idea could be that the Pretty Little Liars characters find themselves in Mystic Falls. Maybe A is somehow related to the supernatural threats in The Vampire Diaries. The liars could team up with the Salvatore brothers to figure out the mystery behind A while also dealing with vampires and witches.
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.
Themes that resonate with the original shows are important. Since both 'The Vampire Diaries' and 'The Originals' deal with themes like family, loyalty, and power, a good crossover fanfiction should explore these themes further. It could show how the different characters from both shows view and handle these themes when they interact with each other.
