Well, a common plot twist is that Harley Quinn's futa identity is a disguise created by someone else to frame her. Batgirl initially believes it and goes after her, but as she digs deeper, she realizes the truth. Also, perhaps there is a magical or technological element that causes their relationship to shift. For example, a spell that makes them swap personalities for a while, leading to some really interesting interactions and a change in their dynamic.
One popular plot twist could be that Harley Quinn, in her futa form, actually has a secret noble reason for her actions against Batgirl at first. Maybe she was being controlled by a greater villain and when Batgirl discovers this, they have to team up. Another could be that Batgirl, instead of being the typical goody - two - shoes, has some hidden desires that are awakened by Harley Quinn's wild nature. This leads to a complex relationship where they both question their own moral standings.
A plot might involve Harley Quinn getting amnesia. Batgirl finds her and decides to help her. In the process of trying to help Harley regain her memory, they form an unlikely bond. But as Harley's memory starts to come back, she remembers that she has a score to settle with some of Gotham's criminals, and Batgirl has to decide whether to support her or stop her.
One possible plot could be that Harley and Batgirl start as enemies but then find themselves in a situation where they have to team up. As they work together, they gradually discover they have more in common than they thought, leading to a newfound respect and an unexpected friendship.
In these fanfictions, Harley Quinn's character might develop from being a more chaotic and self - centered figure to someone who starts to care about Batgirl's well - being. Her futa aspect could add an extra layer of dominance that she has to learn to control, and through her interactions with Batgirl, she may become more empathetic. Batgirl, on the other hand, could develop from seeing Harley Quinn as just a villain to understanding the complex person behind the chaos. She may also become more open - minded and less rigid in her views of good and evil.
One idea could be that Batgirl and Harley Quinn are forced to team up to take down a new supervillain in Gotham. They start off as reluctant allies but gradually come to respect each other's skills. For example, Batgirl is impressed by Harley's acrobatic skills and Harley is in awe of Batgirl's detective work.
A great plot twist could be that Harley Quinn is actually undercover to protect Bruce Wayne from a secret threat that he doesn't even know exists. All her crazy antics are just a cover to keep the real enemy at bay.
Well, perhaps in the fanfic, Harley Quinn has kidnapped someone important, like a scientist who was working on a new technology that could be dangerous in the wrong hands. Batgirl hears about it and goes to confront Harley. There's a series of battles where Harley uses her acrobatic skills and her signature mallet, while Batgirl uses her gadgets and martial arts. In the end, Batgirl manages to rescue the hostage and send Harley back to Arkham Asylum.
A plot twist might be that Harley Quinn has a change of heart not just about the Joker, but also about Gotham's power structure. She decides to help Batman not just against the Joker, but also against some corrupt elements in Gotham that Batman has been trying to expose. So, instead of just being a one - off ally against the Joker, she becomes a long - term partner in cleaning up Gotham.
It could be Batgirl. She has strong willpower and a sense of justice. She's used to being in control in her own battles, so she might carry that over into the relationship with Harley in the fanfiction.
Well, the character development in Harley Quinn Batgirl fanfic can be really fascinating. Since Harley has such a complex backstory, fanfic can further explore her journey towards redemption or her descent into more madness, especially in relation to Batgirl. Batgirl, on the other hand, might have to face new challenges when dealing with Harley. Maybe she has to learn to understand Harley's motives better instead of just fighting her. And the art of world - building in these fanfics is also cool. Writers can create a Gotham City that is even more gritty and dark, or they can add some magical elements that change the whole dynamic between the two characters.
A common theme is the idea of redemption. Harley Quinn is often seen as a character seeking redemption, and Barbara can play a role in that journey. For instance, Barbara might offer Harley a chance at a new life away from crime.
