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.
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.
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 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.
One common theme is the exploration of the relationship between the original character (oc) and Lois. It could be a friendship, a romantic relationship, or a rivalry. Another theme is the integration of the oc into the DC universe. How does the oc interact with other well - known DC characters?
One plot idea could be that the OC is a new villain in Gotham. Harley Quinn becomes yandere for the OC because of their unique style of chaos. She starts to stalk the OC, leaving little gifts that are both disturbing and endearing, like a dead bird with a love note.
For Harley, her yandere trait could develop as a result of her constantly being betrayed in her past relationships. When she meets the OC, she sees them as someone she can finally have complete control over, so she becomes overprotective and possessive.
Well, 'OC x Superwoman: The Beginning' is also a notable one. This fanfiction starts with the OC arriving in the DC world where they first encounter Superwoman. The author does a great job of building the relationship from a very basic level. They face various challenges together, and as the story progresses, the bond between them becomes deeper and more complex.
