There's also 'The Bond of Huntress and Fem OC'. In this fic, the author focuses on how the two characters meet in a rather unexpected situation. The Fem OC has special skills that complement Huntress' abilities. It's a story that delves into their growing relationship and how they face challenges together in Gotham.
A common theme is the 'outsider' status. Both Huntress and the OC are often portrayed as being different from the mainstream superheroes or characters in the DC universe. They might not fit into the traditional hero or villain molds, which leads to interesting character dynamics as they find common ground with each other.
One popular place to find such fanfictions is Archive of Our Own (AO3). Just search for 'dc huntress x oc' there, and you'll get a variety of stories with different themes and writing styles. Some might focus on action - adventures where the Huntress and the Original Character (OC) team up to fight villains in Gotham. Others could be more about the relationship development between them, exploring their personalities and how they interact.
The pairing of DC Huntress and a Fem OC is appealing because it allows for a lot of creativity. Writers can create an OC with unique traits that either contrast or complement Huntress. For example, an OC with a very different moral code can create interesting conflicts and discussions.
There are often themes related to acceptance. The Huntress has to accept the fem oc into her world, and the fem oc has to accept the Huntress's way of life. It could also be about redemption in some cases, where either character has a past mistake or a troubled history and through their relationship with the other, they find a way to redeem themselves. Another theme could be the discovery of new powers or abilities, especially for the fem oc, as she gets involved with the Huntress.
I've heard of 'Huntress and the Mysterious fem oc'. In this fanfiction, the fem oc has a mysterious past that slowly unfolds as she gets closer to the Huntress. It's full of suspense and interesting character interactions. Additionally, 'The Bond between Huntress and fem oc' explores how their bond is formed and strengthened over time through different experiences.
Another theme could be the discovery of self - worth. The OC, who might start as an ordinary person, discovers their own strength and value through their interactions with Katana. For example, Katana might teach the OC some martial arts or give them advice on how to face their fears. As a result, the OC grows as a character. This theme is quite popular as it gives a sense of character development.
One common theme is the power dynamic. Since Superwoman is super - powerful, exploring how the OC with their own abilities or lack thereof relates to her is often a central theme. For example, in many stories, the OC may start off in awe of her power but then find their own strength within the relationship.
Another theme is friendship. Despite their differences, Harley and the OC form a bond. It could start as a reluctant partnership but develop into a real friendship over time. Like in some fanfictions where they go through tough situations together and learn to trust each other.
One idea could be that the OC is a new hero in the DC universe. The yandere Enchantress becomes obsessed with the OC because of their unique powers. She starts to manipulate situations to be around the OC more, like causing villains to attack near where the OC is so she can 'help' and get closer to them.
