I really like 'The Bond Between Slayers'. It's a fanfiction that focuses on the unspoken connection between Buffy and Faith. It has some great action scenes as well as emotional moments that really bring out the depth of their relationship. There are also some interesting plot twists that keep you hooked throughout.
One common theme is love and sacrifice. Since their relationship in the show is complex and full of obstacles, many fanfictions explore how much they are willing to sacrifice for each other. For example, Angel's struggle with his vampire nature and Buffy's duty as the Slayer often lead to situations where they have to make difficult choices for the sake of their love.
One common theme is the clash of different power systems. Naruto has his chakra and jutsu, while Buffy has her slayer strength and combat skills. Writers often explore how these powers interact when the two characters meet. Another theme could be the idea of two heroes from different worlds coming together to fight a greater evil that might be a threat to both their universes.
I really like 'The Lemon Grove Encounter' in the Buffy x Faith fanfic world. It's set in a unique location and shows how their relationship can be both tense and tender at the same time. The writing style is quite vivid, making it easy to picture the scenes in your head.
Sure. Some fanfiction delves into the idea of them being in a relationship. It's an interesting concept as they both have such strong personalities. Writers often play with how they would interact romantically, how they would support each other in different situations, and how their different backgrounds would either clash or blend together in a relationship.
One of the main themes is the exploration of power. As Slayers, they both have power, and fanfics often deal with how they handle it, whether they compete or collaborate. Also, self - discovery is a big theme. They both are on a journey to figure out who they are, especially in relation to each other. For example, Faith might be trying to find out if she can be more like Buffy in some good ways, and Buffy might be learning from Faith's more reckless nature at times. It's a complex interplay of identities.
A common theme is self - discovery. The oc often has to figure out their place in the Buffy - filled world, which is full of danger and magic. Another theme is friendship. They form bonds with Buffy and the Scooby Gang, learning to trust and rely on each other.
One common theme is the exploration of an unexpected relationship. Since Buffy and Marty are from different 'worlds' in a sense, their relationship is full of surprises.
One common theme is the combination of their hunting/slaying skills. Since both are used to fighting the supernatural, fanfics often explore how they work together to take on bigger threats.
Fanfiction.net is also a good place. There are many Buffy - related fanfics there, and you can use the search function to specifically look for Buffy x Willow ones. Just be aware that the quality may vary.
