What are the common themes in 'Buffy and Spike captured baby' fanfics?

I'm not sure of specific 'Buffy and Spike captured baby' fanfics off - hand. You could try searching on fanfic - specific websites like Archive of Our Own. They have a large collection of Buffy - the - Vampire - Slayer fanfics, and you might be able to find ones related to this rather unique scenario there.

Love and family are common themes. The stories often revolve around how Spike and Buffy's love for each other is strengthened by their love for their child. It's about building a family in the midst of their dangerous and chaotic world.

One common theme could be a role - reversal in their relationship dynamic. Instead of Spike being the more 'evil' or morally ambiguous one, Buffy takes on that role. Another theme might be how Spike reacts to this new, evil Buffy. It could be about his struggle between his love for her and his sense of right and wrong.

Another theme is the battle between good and evil within Spike. Given that he's a vampire, there's always that struggle, and Buffy's influence on his choices is a big part of many fanfics. For example, some fanfics might show how Spike's love for Buffy makes him question his vampiric nature and strive to be more 'human' in his actions.

Well, the theme of forbidden love is quite common. Given their different natures (Buffy being a slayer and Spike being a vampire), their relationship is often seen as something that shouldn't be. Another theme is the power dynamic. Buffy is strong and powerful as a slayer, and Spike has his own vampiric powers. How these powers interact and how they balance their relationship around it is a recurring theme. And, of course, there's the theme of sacrifice. They are both characters who are willing to sacrifice for the greater good or for each other in many fanfictions.

One common theme is redemption. Spike's journey towards redemption and how Buffy fits into that is often explored. Another is the idea of forbidden love, as their relationship has always had elements of being something not quite accepted. Also, the theme of sacrifice comes up a lot, like one of them sacrificing for the other's well - being or for the greater good.

One common theme is the exploration of their forbidden love. Buffy and Spike's relationship was always a bit taboo in the original series, and in fanfiction, this is often magnified. Another theme is the power struggle between them, which adds an extra layer of tension to their passionate encounters.

One common theme could be the relationship transformation. The idea of impregnation often changes the dynamic between Buffy and Spike in these fanfics.

One common theme is the struggle with their identities. Buffy is a slayer and Spike is a vampire, so having a baby challenges their usual roles. Another theme could be the reactions of their friends and enemies. Their friends might be shocked or supportive, while their enemies could see it as a weakness to exploit.

A common theme is the exploration of their forbidden love. Since Spike is a vampire and Buffy is a slayer, their relationship is taboo in the Buffyverse, and fanfictions often play on this aspect. Another theme is passion and desire, which is where the 'lemon' part comes in.
