The theme of identity also comes up a lot. Clark in Smallville was always trying to figure out who he was as a Kryptonian and a human. Supergirl has her own identity issues, especially as a female superhero. In crossover fanfiction, they often help each other come to terms with their identities, sharing their experiences and growing together.
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 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.
Perhaps a fanfiction where Supergirl arrives in Smallville during a time when Clark is struggling with his identity. She could be a source of inspiration for him, showing him the full potential of his powers. They could also have a friendly competition to see who can save more people in Smallville, which would be a fun and exciting plot.
Another theme is the exploration of different universes. Sometimes the fanfictions will send the characters into alternate realities where they have to adapt and find their way back. This allows for a lot of creativity in terms of world - building and character development. Also, friendship is often a key theme. These heroes come from different shows but in the crossovers, they form strong bonds and support each other through tough situations.
Another theme is the exploration of different universes. In many crossovers, Supergirl might find herself in a different universe where the rules are different. This allows for interesting plot developments as she has to adapt to new situations and new versions of familiar characters. It also gives a chance to explore what makes her character unique compared to others in different universes.
Lois Lane in Smallville could have an interesting relationship with Supergirl. Lois might be initially skeptical of this new superhero in town. But as she sees Supergirl's selfless acts, she could become an ally and even a friend. And Clark would be in the middle, trying to make sure they both get along. Their relationships would be complex and full of growth as they interact more.
One great Smallville Supergirl crossover fanfiction is 'Smallville's Kryptonian Visitor'. It has an interesting plot where Supergirl lands in Smallville and has to navigate the already complex world of Clark Kent's hometown. The characters are well - written and it stays true to the essence of both shows.
The theme of self - discovery is also prevalent. Supergirl may be on a journey to find out who she really is, not just as a superhero but as a person. This can include exploring her likes, dislikes, and her place in the universe.
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.
Another theme is the struggle with identity. The pregnant character may question who they are now and how they will be perceived. In the context of Smallville, which has its own set of values and expectations, this can be a big part of the story.
