Another theme is friendship and relationships. Fan fictions often focus on her relationships with her friends at work or other superheroes. They might show how she bonds with them, like in some fictions where she teams up with other female superheroes to fight a common enemy and in the process, their friendship grows stronger.
One common theme is redemption. Often, the stories show Flint as a place in need of help and Supergirl brings about positive change, almost like redeeming the city.
A common theme is the contrast between their powers. Batman is a human with no superpowers, relying on his intellect and gadgets, while Supergirl has superhuman strength, flight, etc. Their partnership is also a big theme, like how they learn to work together despite their differences. Another theme can be the protection of their respective cities, Gotham for Batman and Metropolis (where Supergirl also has a connection) from threats.
One common theme could be Kara's emotional struggle. She is a strong character, and a miscarriage would shatter her, leading to themes of grief and self - doubt. Another theme might be the reaction of her friends and family. They would be there to support her, showing themes of love and unity in difficult times. Also, it could explore how she copes with the loss and whether it changes her superhero identity, like making her more empathetic towards others who have suffered losses.
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.
Another theme could be rescuing innocent bystanders. For instance, they might save people trapped in a burning building or those being held hostage by bad guys. This shows their heroic nature. Also, sometimes they rescue other superheroes who are in trouble, which emphasizes the sense of community among superheroes in the fan fictions.
Love and romance can be a theme in some cases, not necessarily between Arrow and Supergirl directly, but perhaps within their respective teams or with other characters they interact with in the fanfiction world. It adds an extra layer of complexity to the relationships and the overall story.
A third common theme is the exploration of new powers. Since these are original characters, they often have powers that are different from what we've seen in the regular Supergirl story. Writers like to play with these new powers and how they can be used in different situations, like fighting new villains or solving problems in National City.
In Arrow and Supergirl fanfics, the theme of friendship or romance can also be common. Some writers like to explore the possibility of a romantic relationship between them, while others focus on a strong platonic friendship. Additionally, the theme of facing a greater threat together is quite prevalent. This could be an alien invasion or a super - villain that is too powerful for either of them alone. Fanfics use these themes to create exciting and engaging stories.
One common theme is the 'fish out of water' concept. Since Supergirl is an alien and Spiderman is a street - level hero in a different world, their interactions often involve one or both of them feeling out of place in the other's environment.
Another theme is the idea of two different worlds colliding. Percy is from a world of Greek mythology, while Supergirl is from the DC Comics universe. Fanfics usually deal with how Percy adapts to the modern, high - tech world of Supergirl and how their two worlds can co - exist in the story.
