One common theme could be the struggle between good and evil. Even in a relationship - centered fanfic, Batgirl represents good and the Joker represents evil, and their interactions can be a microcosm of that larger struggle.
A prevalent theme could be the power of influence. Batgirl might try to influence the Joker to change, or vice versa. Their relationship could be a tug - of - war of different ideologies. And there could also be a theme of secrecy. Since Batgirl is a hero and the Joker a villain, any relationship between them would likely be shrouded in secrecy, which could add an element of mystery and danger to the fanfic.
The themes usually revolve around their relationship dynamics. There's the theme of power struggle as they both have their own kind of power. Poison Ivy with her control over plants and Batgirl with her combat skills and detective abilities. Additionally, themes of trust and betrayal can be found in many of these fanfics. Sometimes they start off not trusting each other but then gradually build that trust as the story progresses. And of course, the theme of female empowerment as they are both strong female characters.
One common theme is the relationship between good and evil. Batgirl represents the side of justice, while Ivy is often seen as a villain. Fanfics might explore how their different moral stances interact and whether they can find common ground.
Well, a frequent theme is the power dynamic between them. Given that Catwoman is a more experienced and sometimes morally ambiguous character compared to Batgirl, fanfics often explore how this affects their relationship. Also, themes of redemption and acceptance are common. As Catwoman is an anti - hero, fanfics may show how Batgirl's positive influence can lead to Catwoman's further redemption, all within the context of their relationship. There's also the theme of their shared love for Gotham, but in different ways, and how that can bring them closer together in a romantic sense.
One common theme is the exploration of the Joker's madness from the reader's perspective. It could be about how the reader tries to understand the Joker's erratic behavior and the chaos he brings. Another theme is the power dynamic. Sometimes the reader might be in a position of power over the Joker, like a psychiatrist trying to analyze him, or vice versa, and they play a mental game of cat and mouse.
The theme of duality is quite common. They are two sides of the same coin in a way. Fanfics such as 'The Dual Nature' explore this concept. Batman's dark and brooding nature against Joker's maniacal and colorful chaos. Another theme is the mystery around Joker. Fanfics often try to dig deeper into his past and motives. 'Unraveling the Joker' is a fanfic that focuses on trying to understand what made Joker who he is, without any mpreg - related stuff. Also, the theme of hero - villain relationship is explored in a lot of fanfics, like 'The Hero and the Villain' which looks at how they are defined by their relationship to each other.
A common theme is friendship. They are both strong female characters from different superhero backgrounds (Kara being from Krypton and Batgirl being part of the Batman family), and fanfictions often explore how they form a deep friendship.
One common theme is the clash of their different worlds. Spiderman comes from the Marvel universe with its own set of rules and Batgirl from DC. Another is the exploration of their powers working together. For example, Spiderman's agility and web - slinging combined with Batgirl's combat skills.
Well, friendship and romance are quite common. Writers like to explore how these two characters from different universes could form a deep bond. Also, adventure is a big theme. They might go on quests together, either in the Naruto world or in Gotham. In some fanfictions, they have to overcome differences in their ideologies. Naruto believes in protecting his village and friends at all costs, while Batgirl has her own code of justice in Gotham, and seeing how they reconcile these differences can be an interesting theme.
A frequent theme is the power dynamic. Batman is often seen as the more powerful one in the traditional sense, but in these fanfics, the Joker's love gives him a different kind of power. It's the power to disrupt Batman's life, to make him question his own beliefs. Also, the theme of redemption sometimes creeps in. There are fanfics where the Joker's love for Batman is seen as a possible path towards his own redemption, though it's always a very twisted and complex idea.
One common theme is friendship. They are both strong female characters in the DC universe, so fanfics often explore how they support and learn from each other. For example, they might team up to fight a common enemy and in the process, strengthen their bond.
