The theme of protection also often comes up. Harley may have to protect herself and her unborn child from various threats in the dangerous world she inhabits. Fanfics might explore her using her skills and wits in new ways to ensure the safety of both herself and her baby, while still maintaining her unique Harley Quinn charm.
One common theme is Harley's struggle with her new identity as an expectant mother. Given her chaotic and often unpredictable nature, the fanfics might explore how she copes with the idea of bringing a new life into the world.
Another theme could be the relationship dynamics. For example, how her relationship with the Joker or other characters in the Harley Quinn universe changes when she's pregnant. It could be about the Joker's reaction, whether he's supportive or not, or how other allies or enemies view her in this new state.
A prevalent theme is often about relationships. It could be her relationship with the father of the child, if it's the Joker, how that dynamic changes. Or it could be about her new relationships she forms with other characters who support her during the pregnancy, like other female characters from the DC universe.
One common theme is redemption. Harley Quinn has a complex past, and in many fanfics, including those involving Harry, she is on a path to redeem herself. Another theme is friendship or an unlikely alliance. Harry and Harley Quinn coming from different backgrounds and yet finding common ground.
One common theme could be the character's journey through pregnancy, dealing with the physical and emotional changes. Another might be how the other characters in the story react to Quinn's pregnancy, whether it's with support or some kind of conflict.
Friendship is also a big theme. Many fanfics show them forming an unlikely bond. They might start off as enemies or strangers but end up as friends who support each other. It's interesting to see how their different backgrounds and values contribute to this friendship. Like in some stories, Harley helps Wonder Woman understand the darker side of humanity while Wonder Woman helps Harley find her moral path.
One common theme is the redemption of Harley Quinn. In many fanfics, she tries to break free from the Joker's influence and find a new path, often with Batman's help or at least his begrudging acceptance. Another theme is their complex relationship, whether it's a romantic one or just a mutual understanding that defies their traditional 'villain - hero' dynamic.
A prevalent theme is the exploration of Harley's transformation. In these fanfics, she usually moves from being a villain associated with the Joker to someone who might be on the side of good because of her feelings for Batman. Also, the theme of forbidden love is often there. Given their opposing natures and Batman's no - killing code, a relationship between them is not something that would be easily accepted in the Batman universe.
Another theme is chaos and adventure. Since Harley Quinn is often associated with mayhem in Gotham, the OC gets dragged into her wild adventures. They might face off against other villains or try to outwit the Batman together, which makes for exciting reading.
Friendship is another big theme. Despite their different personalities, they form a bond. In some fanfics, they start out as rivals but gradually become friends. Their friendship is shown as something that makes them stronger. For instance, they might help each other out of tough situations like escaping from Arkham Asylum.
One common theme is identity. The oc, being Harley Quinn's child, has to figure out who they are. Are they going to follow in their mother's footsteps or forge their own path? Another theme is family. Even though Harley has her own quirks, the oc might still have a strong bond with her or struggle with the idea of family due to Harley's lifestyle.
One common theme could be friendship tested. Since Quinn and Rachel might have a complex relationship in the show, the fanfic could explore how this unexpected pregnancy affects their friendship. Another theme might be self - discovery. Quinn may have to reevaluate who she is and what she wants in life now that she's pregnant. Also, it could deal with family reactions, as both of their families would surely be involved in such a situation.
