The theme of good vs. evil in different contexts is also common. In Smallville, Clark is growing up and learning about his role in fighting evil, while Buffy is already in the thick of it. In the crossovers, they might compare notes on how to handle demons, vampires, and other threats. Also, the idea of protecting the innocent is central in both shows, and in the fanfics, they may join forces to do so in new and exciting ways. This can involve not only physical battles but also moral dilemmas and decisions that test the characters' beliefs and values.
A common theme is the clash of two different worlds. Smallville is more of a small - town superhero origin story, while Buffy deals with the supernatural in a more urban and 'chosen one' kind of way. So, the fanfics often explore how these two concepts collide.
Another theme is the power struggle. Smallville often focused on Clark's journey to control his powers, and Supergirl has her own power - related challenges. In crossovers, they might face a common enemy where their combined powers are needed, and this creates a power struggle dynamic as they figure out how to work together effectively.
A common theme is the rekindling of their relationship. Whether it's a romantic or a platonic bond, it often focuses on how they reconnect. Another theme is the fight against a greater evil. Since both are from the Buffyverse which is full of demons and dark forces, this is a natural theme.
Love and sacrifice are common themes. Their relationship has always been about love in different forms and often one has to sacrifice for the other. So in crossovers, this is often explored further.
One common theme is the clash of different worlds. Buffy's world of demons and magic and Stargate's world of aliens and advanced technology. Another theme could be the exploration of power. How the powers of the Buffy characters like slayers compare to the military might and technology in Stargate.
One common theme is the clash of different cultures. Buffy's world has a lot of supernatural elements and a modern - day Earth - like setting in some ways, while Firefly has a more space - western feel. So when the two worlds collide, there's often exploration of how these different cultures interact.
A common theme is the clash of different supernatural rules. Buffy has her own set of vampire and demon lore, and Anita has a very different set in her world. Fanfictions often explore how these different systems interact.
One common theme is the clash of different cultures. Buffy comes from a modern world with a certain set of values and fighting styles, while Middle - earth has its own ancient and more traditional ways. So, the stories often explore how these differences play out when she arrives there.
There's a fanfic called 'The Buffy - Smallville Connection'. In this story, the writers manage to bring the different elements of both shows together. It has some great character development, especially for characters who cross over from one world to the other. They face new challenges and it makes for an exciting read.
One common theme is the exploration of their unrequited love. Often, in the show, there were hints of something more between Clark and Chloe, and fanfiction delves into that unfulfilled potential.
The theme of secrecy also pops up a lot. The vampire has to keep their true identity a secret in Smallville. This leads to situations where they have to lie and deceive the people around them, which adds to the tension in the story.
