Well, in fanfiction, their relationships are all over the place. Batman is the moral compass, always trying to stop Poison Ivy and Harley Quinn's antics. But sometimes, the writers play with the idea that Poison Ivy could be an ally in certain environmental cases. Harley Quinn, on the other hand, has a wild card relationship with Batman. She might flirt with him just to mess with his head while still being loyal to the Joker. It really depends on the writer's take on these characters.
In many fanfictions, Batman's relationship with Poison Ivy and Harley Quinn is complex. Batman often tries to bring them to justice. However, some fanfictions explore a more nuanced side. For example, Poison Ivy might see Batman as an enemy who also respects nature to some extent. Harley Quinn's relationship with Batman can be a love - hate one, where she is attracted to his strength and sense of justice but is also on the side of chaos with the Joker. In some stories, they form an unlikely alliance against a greater threat.
In some fanfictions, their relationship starts as pure enmity. Batman is constantly trying to stop Poison Ivy and Harley Quinn's criminal activities. But as the story progresses, they might find common ground. For example, they all might have a shared enemy that forces them to work together briefly.
One possible fanfiction could be about Batman trying to reform Poison Ivy and Harley Quinn. Maybe he sees potential in them to turn away from their criminal ways. He could start by trying to understand their motives better, like Ivy's love for plants which has led her to extreme actions to protect them, and Harley's loyalty to Ivy which has made her follow along in the chaos.
Imagine a fanfiction where a new super - weapon is being developed in Gotham. Poison Ivy and Harley Quinn get wind of it and decide to steal it, thinking it could be used to further their own goals. Batman, of course, is trying to stop them. But as the story unfolds, they all realize that the weapon is far more dangerous than they initially thought. So, instead of fighting each other, they have to work together to destroy the weapon before it destroys Gotham. This forces them to put aside their differences and form an unlikely alliance.
Well, there are quite a few tropes. There's the 'captivity' trope where Batman captures Poison Ivy or Harley Quinn, and during the captivity, they have some deep conversations that change their views of each other. Also, the 'identity swap' trope can be seen sometimes, where the characters' personalities or identities are somehow switched, leading to some really strange and interesting interactions. And don't forget the 'frenemy' trope, which is very prominent. They act like enemies most of the time but can be friends or allies when the situation calls for it.
Another could be a love triangle of sorts. In the fanfiction, Poison Ivy might be jealous of Harley Quinn's growing friendship with Batman. Harley is caught in the middle, torn between her loyalty to Ivy and her newfound respect for Batman. This creates a lot of tension and interesting character dynamics.
Yes, they do have some romantic interactions in certain comic storylines.
Love triangles are quite common. There could be a love triangle between Batman, Harley Quinn, and Poison Ivy. Sometimes Harley might be caught between her old feelings for the Joker and new feelings for Batman or someone else. The theme of female empowerment is also prevalent. Fanfics often showcase Poison Ivy's strong connection to nature and her ability to use it as a force, and Harley Quinn's growth from a sidekick - like figure to a more independent character.
The relationship between Harley Quinn and Poison Ivy in the graphic novel is significant as they are often shown as very close friends. They support each other in their various escapades. Ivy's calm and calculating nature often balances Harley's more erratic behavior.
I really like 'Harley and Ivy: Partners in Crime'. In this fanfiction, their personalities are spot - on. Harley's wild and unpredictable nature combined with Poison Ivy's calm and calculating demeanor makes for an exciting read. It also has some really cool plot twists that keep you hooked from start to finish. There's also 'A Tale of Two Outcasts' which delves deep into their backstories and how they came to be friends and partners.
In some fanfiction, a really interesting storyline is when Harley and Ivy get separated for a while. It shows how much they rely on each other. Harley starts to lose her spark without Ivy around, and Ivy feels a bit lost without Harley's energy. When they finally reunite, it's a very emotional moment, and they realize how important their friendship is in the chaotic world of Gotham.
