Perhaps a moment when Kara is feeling down because she misses her home planet. Diana, knowing how she feels, arranges a surprise for her. She gathers items from different parts of the world that remind Kara of Krypton. This small gesture of thoughtfulness and love can be really touching in the context of the fanfiction.
Their relationship might start with mutual admiration. Diana sees Kara's strength and kind heart, while Kara is in awe of Diana's power and wisdom. As time goes on, they face challenges together, which deepens their bond. For example, they might team up to stop an intergalactic threat, and through that experience, they start to rely on each other more.
A common trope is the 'enemies to lovers' arc. At first, Lena might be a bit suspicious of Kara or vice versa, especially considering Lena's family history and Kara's secret identity. But as the story progresses, they see past their initial differences and fall in love. Also, the 'love triangle' trope can be found, although not as often. Maybe there's a third character who has feelings for either Lena or Kara, which adds some drama and tension to the relationship. And the 'found family' aspect is important too. Their relationship is not just about romantic love but also about building a family - a support system where they can be themselves and rely on each other.
One interesting storyline could be Kara adjusting to life on Earth as a young girl. Maybe she's trying to hide her powers while also making friends at school. Another could be her learning about her Kryptonian heritage in a more personal way, like finding a hidden family heirloom that gives her new insights.
The cuteness factor. Baby Kara is just so adorable in these fanfictions. It's like seeing the powerful Supergirl in a completely new and vulnerable state.
In some fanfictions, a character might be going through a supernatural or dangerous experience. For example, they could be facing a spooky ghost in an old house. When they finally escape and get home, their mom gives them a tight hug. It's a moment of safety and love. The mom's hug is like a shield protecting the character from all the bad things that just happened.
Well, obviously Kara herself is a common character. Then there's often her adoptive family, like the Danvers. Alex Danvers, her sister, is frequently in these fanfictions. They usually have a strong bond that's explored further. Also, Clark Kent might make an appearance. Since he's also from Krypton, he can act as a mentor or a source of information for Kara about their home planet.
Archive of Our Own (AO3) is a great place to start. It has a vast collection of Supergirl fanfictions, including many where Lena loves Kara. The site has a good tagging system, so you can easily filter for the specific relationship and other elements you like. Fanfiction.net is also an option, although the interface might be a bit less user - friendly compared to AO3. You can also check out some Supergirl - focused fan communities on platforms like Tumblr. Often, users there will recommend their favorite fanfictions, and you might find some real gems.
In Supergirl fanfiction, a pregnancy involving Winn and Kara can be a very interesting plot device. It could bring out different aspects of their characters. For example, Winn might show his more protective side. However, in the official storylines, there's no such plot, so fanfiction gives writers the freedom to explore this uncharted territory.
Some fanfictions might focus on the father of the baby. If it's Mon - El, there could be a lot of drama as they navigate their relationship in this new phase. It could also show Kara learning about motherhood and how her powers might be affected during pregnancy.
The new perspectives. An OC (original character) can bring in fresh ideas and storylines. For instance, an OC could have a unique power that changes the dynamics in the Supergirl world.
