Well, Spike is a really popular choice. He's got that bad - boy vampire charm and his history with Buffy makes for some really intense storylines. Another character that gets paired with Buffy when she becomes a vampire is Willow. Their friendship takes on a whole new dimension, especially if Willow tries to find a way to reverse Buffy's vampirism or has to deal with her new vampire friend in a world that's now very different for both of them.
Spike is often paired with Buffy in this type of fanfiction. Since they already had a complex relationship when Buffy was a slayer, it becomes even more interesting when she becomes a vampire. Angel is also a common pairing. Their past relationship and his own experience as a vampire with a soul add a lot of depth to the story.
One of the most common characters paired with Buffy in this kind of fanfiction is Giles. He has been her mentor for so long, and when she becomes a vampire, his role becomes even more complex. He might try to find a way to save her or have to deal with the fact that she's now on the 'other side'. And of course, Spike is also frequently paired with her. Their relationship can range from him trying to take advantage of her new vampire state to actually falling in love with her all over again in a different way.
Definitely Spike. He has his own complex relationship with Buffy. In the fanfiction, he could be a mentor of sorts to Buffy, teaching her how to be a 'better' vampire, or he could see her as a rival in the vampire world. Giles would also be around. He'd be the voice of reason, trying to figure out what caused Buffy's transformation and looking for ways to reverse it while still guiding the Scooby Gang.
Definitely Buffy. She's the one who the whole story revolves around. Her courage and determination make her a fan favorite. Angel is another popular character. He's a vampire with a soul, and his relationship with Buffy is full of drama and emotion. Xander is also popular among readers. He may not have special powers like Buffy or Willow, but his loyalty and humor are endearing.
Buffy and Luke Skywalker could be an interesting pair. Buffy is a strong fighter and leader in her world, and Luke is a key figure in the Star Wars universe. They could learn from each other's combat styles and leadership skills.
Buffy herself is quite popular. Fans like to see how she'd interact with the Twilight characters. Edward also often features prominently as his brooding nature contrasts with Buffy's more action - oriented personality. Another popular character is Spike from Buffy. His edgy vampire persona can create interesting dynamics when paired with the Twilight vampires.
Buffy herself is very interesting. She's a strong, independent girl who has to deal with both high school drama and vampire slaying. Spike is also cool. He's a vampire with a complex personality, sometimes an enemy, sometimes an ally. And Willow, Buffy's friend, is interesting too. She has her own journey with magic.
Well, Angel is really interesting. You can play with his tortured soul concept. There are so many possibilities in fanfiction, like exploring what would have happened if he had made different choices regarding his relationship with Buffy. And Faith is also a great character to write about. Her rebellious nature and her struggle with her slayer identity give a lot of room for creative stories.
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.
Buffy herself is often a very popular character in Wishverse fanfic. Writers like to explore different versions of her, like a more jaded Buffy in a darker Wishverse. Spike is also popular as his complex character can be taken in many new directions in the alternate reality. And Willow, given her powerful magic, can have some really interesting storylines in the Wishverse.
I think Giles is one of the most interesting characters. He's Buffy's Watcher, guiding her in her slayer duties. He has a lot of knowledge about the supernatural. Another interesting character is Faith. She's also a slayer, but she has a much darker side compared to Buffy. And Angel, the vampire with a soul, his inner struggle between his vampire nature and his human side makes him really engaging.
Definitely Spike. He has such a complex character arc in the show. His transformation from a bad - boy vampire to someone with a conscience makes him a really interesting subject for fanfiction. Writers can explore his inner thoughts and feelings more deeply. Another one is Drusilla. Her insanity and her unique relationship with Spike give a lot of room for creative writing.
