Well, a great storyline might be them starting a new life outside of Gotham. They find a small town that has a lot of abandoned areas, and Poison Ivy starts to transform those places with her plants. Harley Quinn helps her by making friends with the locals. They face some challenges like dealing with local bullies who don't like their new 'green' ways. But in the end, they make the town a beautiful and unique place that accepts them for who they are.
One interesting storyline could be them going on a heist together. They use Poison Ivy's plant powers to create distractions and Harley Quinn's acrobatic skills and unpredictability to get past security. Another could be a story where they rescue each other from the clutches of a common enemy. For example, if the Joker tries to harm Harley, Poison Ivy uses her vines to snatch her away. And they could also have a story where they go on a journey to find a rare plant that has the power to make Harley immune to all toxins, which would be very useful in their dangerous Gotham lives.
A possible storyline is that they discover a hidden underground world beneath Gotham. It's full of strange plants and creatures. Poison Ivy is naturally drawn to it because of the plants, and Harley Quinn is excited for the adventure. They have to work together to navigate through this new world. There are some traps and puzzles that they need to solve. Along the way, they also learn more about each other's pasts and become even closer friends.
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.
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.
One popular storyline is their adventures in Gotham City together. They might be causing chaos against the villains who oppose them or even teaming up to outwit Batman. Another could be their relationship development, like how they support each other through tough times. For example, in some fanfictions, Poison Ivy uses her plant powers to protect Harley Quinn when she gets in over her head in a fight with some of the Joker's goons.
Perhaps the story could focus on how Harley Quinn and Poison Ivy adjust to their new family dynamic. Harley might be the more impulsive and fun - loving parent while Poison Ivy is more protective and nurturing. The baby could also bring out a softer side in their villainous personas, leading them to consider a more peaceful existence.
One possible plot could be that they are in a garden, Poison Ivy's domain. As they kiss, the plants around them start to grow and bloom more vibrantly, as if sharing in their joy. It could symbolize their relationship making the world around them more alive.
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.
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.
There could be a plot where Poison Ivy discovers a new type of plant that has the power to make people tell the truth. Harley gets curious and tries it on some of the bad guys in Gotham. Meanwhile, Ivy is worried that this new plant could attract unwanted attention from the government or other powerful forces. They have to decide whether to keep it a secret or use it for their own purposes.
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.
Well, in Poison Ivy and Harley Quinn fanfiction, a common theme is their loyalty to one another. They are like two peas in a pod. Ivy's connection to nature can sometimes be used to protect Harley. For example, she might use her plants to create a hiding place when they're on the run from the police or other bad guys. And Harley, in turn, is always there to cheer up Ivy when she's feeling down about her failed attempts at environmental conservation in Gotham.
