There are several. The theme of obsession is frequently seen. Harley's obsession with Batman is a big part of their relationship in fanfiction. Also, the idea of Batman being a source of stability or hope for Harley in some stories. And the exploration of their shared Gotham city, how their relationship is affected by the city's dark and dangerous environment.
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.
Yes, there are many. You can find some on popular fanfiction websites like Archive of Our Own. Some explore Harley's complex relationship with Batman, often delving into her chaotic nature and how it interacts with Batman's sense of justice.
Power dynamics is another theme. Given Harley Quinn's complex relationship with power, especially in relation to the Joker, the male oc can bring a new element to this. Maybe he has his own power struggle within the DC underworld, and his relationship with Harley Quinn either complicates or simplifies that struggle. It could also involve themes of loyalty and betrayal, as in the world of DC, alliances can be fickle.
One common theme is redemption. Harley Quinn trying to redeem herself in Batman's eyes and him falling for the new her. Another is the idea of breaking free from toxic relationships, like Harley's with the Joker, and finding something healthier with Batman.
Well, the theme of transformation is quite common. Harley may transform from a villain or anti - hero to a more heroic figure because of her relationship with Batman. There's also the theme of trust. Batman has to learn to trust Harley, who has a checkered past. And Harley has to learn to trust Batman not to use her or betray her. These themes add depth to their relationship in the fanfiction world and make for some really engaging stories.
Common themes include the idea of morality. Batman has his strict moral code, while Harley Quinn's moral compass is a bit more...skewed. Their encounters in fanfiction often highlight this contrast. And there's the theme of Gotham itself. The city serves as a backdrop and sometimes almost a character, with its dark alleys and seedy underworld being the setting for their battles.

Their marriage is sometimes seen as a sign of a new, more positive Gotham where former villains can be rehabilitated.
One common theme is redemption. Harley Quinn is often seen as a character in need of saving from her life of crime and insanity, and Batman is the one to do it. Another theme is the power of friendship or mentorship. Batman could be seen as a mentor to Harley, guiding her towards a better life.
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.
