One popular Buffy and Vampire Diaries fanfiction might be those that explore a crossover between the two universes. For example, a story where Buffy Summers meets the Salvatore brothers. It could be interesting to see how their different vampire - slaying and vampire - being concepts interact.
One popular theme is the relationship between the characters. In both shows, there are complex love triangles and friendships that fanfiction often explores further. For example, in The Vampire Diaries, the relationship between Elena, Stefan, and Damon is a huge draw for fanfiction writers. Another theme is the battle between good and evil. Buffy's slayer duties and the vampires in The Vampire Diaries provide ample material for stories centered around fighting the forces of darkness. Also, character backstories are often delved into. Writers might create stories about how a character became a vampire or how Buffy got her slayer powers in the first place.
Perhaps a spell gone wrong in the Buffy universe causes some of the main characters from there to swap bodies with characters from The Vampire Diaries. This could lead to humorous and tense situations as they try to figure out how to reverse the spell while still dealing with the threats in each other's worlds.
Tumblr can be another source. There are often fanfiction writers who post snippets or links to their full - length Buffy and Vampire Diaries fanfictions on their blogs. You can search relevant hashtags to discover new and interesting stories.
I think Klaus from The Vampire Diaries would also be a very powerful character in a crossover. He's an original vampire - werewolf hybrid with incredible strength and a very cunning mind. But Buffy has the power of the slayer, which gives her enhanced physical abilities and a sort of sixth sense for the supernatural. If they were to face off, Buffy's slayer instincts might give her an edge, but Klaus's raw power and immortality would make it a tough fight.
In The Vampire Diaries, Elena and the Salvatore brothers, Stefan and Damon, are extremely popular. Elena because she is the central female character and her relationships with the two vampire brothers are so complex. Stefan is often written about because of his brooding nature and his struggle with his vampire side. Damon, with his bad - boy charm, is a favorite too. In Buffy, Buffy herself is a very common character in fanfiction. Her role as the slayer and her relationships with her friends like Willow and Xander make her a prime choice. Spike is also very popular, especially his relationship with Buffy which is full of tension and emotion.
One popular theme is alternative universes (AUs). For example, stories where the characters are in a modern - day high school but with a supernatural twist different from the show. Another is character relationships. Fans often explore different pairings, like Damon and Bonnie, which might not be as prominent in the original series. And there are also time - travel themed fanfics, where characters go back in time to change certain events in the Vampire Diaries timeline.
Goodreads also has a section for fanfiction sometimes. Although it's not as well - known for fanfiction as the other sites, it can still be a source. Look for groups related to The Vampire Diaries and see if anyone has recommended or shared fanfictions. Also, keep an eye on Reddit. There are subreddits dedicated to fanfiction in general and The Vampire Diaries specifically where people post and discuss their favorite stories.
A must - read vampire Buffy fanfiction is 'Shadows of the Night'. This one shows Buffy dealing with a new breed of vampires that are much more cunning and powerful. The author does an excellent job of building the tension throughout the story.
Well, it depends. While some fanfiction can be really great for exploring more of the 'Vampire Diaries' universe, there's also a lot of poorly written stuff out there. But if you find good quality fanfiction, it can offer new perspectives on the characters and their relationships. For example, you might get to see different pairings or how a character would react in a completely different situation than in the show.
