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.
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.
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.
If Barry kidnapped Supergirl in fanfiction, it could be a really interesting plot twist. Maybe Barry has been affected by some sort of red kryptonite - like substance that makes him act out of character. This would lead to a conflict between the Flash and Supergirl's friends and allies. They would be confused as to why Barry would do such a thing.
One inspiring Supergirl story is her fight against powerful villains to protect Metropolis. She uses her super strength, flight, and heat vision to keep the city safe. For example, when a group of alien invaders threatened the city, Supergirl was the first to stand up and fight them off, showing great courage.
Supergirl is a popular character in fanfiction. Writers love to explore her powers, her dual identity, and her relationships. Her superhuman abilities make for exciting action scenes, and her kind heart makes her a beloved hero in many stories.
