One great Alex Danvers and Lena Luthor fanfiction is 'The Bond Beyond'. It focuses on their unexpected friendship turning into a powerful alliance to save the city. Another good one is 'Unlikely Partners' which delves into their different worlds colliding in a scientific adventure. And 'Shared Secrets' shows how they gradually open up to each other about their past traumas and grow closer as a result.
One great Lena Luthor and Alex Danvers fanfiction is 'Allies in the Shadows'. It really delves into their complex relationship as they team up to solve a mystery within the Supergirl universe. The author does an amazing job of showing their different personalities clash and then gradually come to understand each other better.
Another theme is friendship. They often start as acquaintances or even adversaries and then develop a deep friendship. In some fanfictions, this friendship is what helps them both grow as individuals. Like, Lena becomes more open and less guarded, and Alex becomes more understanding of the gray areas in people's personalities.
Another theme is redemption. In some fanfics, Lena is often on a journey of self - redemption, trying to prove that she is not like the other Luthors. Alex can play a big part in this, either by believing in her from the start or gradually coming to see her true self. Fanfics like 'Lena's Path' explore this theme in depth, showing how their relationship is intertwined with Lena's quest for redemption.
AO3 is probably the best place to find high - quality Alex Danvers and Lena Luthor fanfiction. It has a tagging system that makes it easy to filter stories based on your preferences, like if you want a story with a specific genre or rating. Additionally, Tumblr often has fanfic recs (recommendations) from the fandom. You can search for tags related to their relationship on Tumblr and might find some great suggestions there.
There's also 'The Unlikely Bond'. This fanfic focuses on how Alex and Lena, coming from different backgrounds (Alex as a DEO agent and Lena as a Luthor), gradually form a deep and trusting friendship. It shows their interactions in various situations, like during a city - wide crisis and in more personal, quiet moments.
I really like 'Lena and Kara: A New Beginning'. In this fanfic, the author delves into their backstories and how those shape their present interactions. It also has an interesting plot where they have to work together to save their city from a new threat. It's full of action and emotional moments.
There's also 'Heartbeats in Harmony'. In this fanfiction, Kara and Lena face a common enemy that forces them to rely on each other even more. The story is filled with action scenes and at the same time, the development of their relationship is at the forefront. It's a great read for fans of the two characters.
One possible fanfiction could be about Lena Luthor becoming a mentor to young Kara Danvers. Lena, with her intelligence and resources, could help Kara understand the complex world around her while also learning to control her powers better. Maybe Lena discovers Kara's identity early on and decides to guide her in secret, away from the prying eyes of Lex Luthor and other potential threats.
Kara and Lena are both strong, interesting characters on their own. Kara is Supergirl, with her powers and moral compass, and Lena is a brilliant scientist and businesswoman. When you put them together in a fanfiction, especially in a romantic context as in the 'lemon' genre, it creates a really appealing combination. Fans are drawn to seeing how their powers and personalities interact, and how they might overcome obstacles in a relationship. It's also about the exploration of the 'forbidden' or 'taboo' nature of their relationship in some cases, which adds to the allure.
