Well, there is some. I've seen some really interesting ones where the writers explore their relationship in different ways. Some might focus on a slow - burn love story, while others might put them in alternate universes. You could also try Wattpad, as it also has a collection of Klaus and Davina love fanfictions.
Archive of Our Own (AO3) is a great place. It has a large collection of fanfictions, and you can easily search for Klaus and Davina love stories there.
Well, 'The Redemption of Klaus through Davina' is a fan favorite. In this fanfiction, Davina becomes the key to Klaus's redemption. It's a beautifully written story that shows how love can change even the most hardened of hearts. 'Davina and Klaus: The Unexpected Friendship' is also good. It begins with them being forced into a situation where they have to rely on each other as friends first, and then slowly romantic feelings start to develop.
The popularity of 'davina and klaus fanfiction' comes from the complex and intense nature of their relationship in the original series. Their characters are so different - Davina is young and powerful, while Klaus is old and has a dark past. Writers love to explore how these two could interact, whether it's in a romantic or a more platonic way of power - sharing and mutual respect.
One common theme is the power struggle. Given Klaus's powerful vampire nature and Davina's strong magic, there's often a play of power between them. Another theme is redemption. Klaus is often seen as a villain, and in some fanfictions, Davina helps him find a path to redemption.
One popular klaus and davina fanfiction is 'A New Bond'. It delves into their relationship in a really interesting way, exploring how their different personalities interact. It has some great dialogue that really brings the characters to life.
It's not really appropriate. Kol and Davina are characters from a story, and while fanfiction allows for creative interpretations, focusing on sexual encounters in a fan - created story can overshadow other aspects of their relationship, like their emotional bond, the development of their characters, and the overall plotlines in the original work. Moreover, it may violate the ethics and guidelines of the fan community.
One possibility for a great love interest for Klaus is a human. A human would bring out the more humane side of Klaus. The contrast between his immortal, powerful self and the mortal, fragile human would create a lot of interesting dynamics. The human could be someone who is initially afraid of him but then sees the good in him. Also, an original vampire from another family could be an interesting love interest. This would involve a lot of power plays and political intrigue within the vampire world. They would understand each other's nature and the responsibilities that come with being an original, but at the same time, there could be rivalries between their families that add to the story.
Klaus shows his love by protecting Caroline. He would always be there to save her from any danger, whether it's from other vampires or supernatural threats.
It's very possible. Fanfiction writers often come up with various scenarios for their favorite characters. Since Davina Claire is a character that some fans may be interested in, it's not uncommon for there to be a fanfiction where she is pregnant. You can also try searching on Tumblr, as sometimes users share or recommend fanfictions there.
