One possible scenario in this fanfiction could be Naruto finding himself in the chaotic world of Harley Quinn and Poison Ivy. Maybe Naruto's ninja skills would be put to the test against the various villains in their world. He could use his shadow clone jutsu to confuse enemies like the Joker or other foes that Harley and Ivy often face.
Perhaps in this fanfiction, there would be a cultural exchange of sorts. Naruto would share his ninja culture, including things like the importance of the headband and the code of the ninja. Harley and Ivy would be fascinated by this and might even incorporate some ninja - like elements into their own styles. On the other hand, they would show Naruto the wild and wacky side of their world, from the crazy villains to the unique architecture of their city.
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.
It's hard to pick just a few 'best' authors. However, 'Amber Flame' is known for her very creative storylines. She might take the two characters on a time - traveling adventure or have them encounter alternate versions of themselves. 'Crimson Leaf' is also popular. His stories usually have a darker, more edgy feel to them, which can be really interesting when exploring the complex personalities of Poison Ivy and Harley Quinn. There are many other talented authors out there too, constantly adding to the rich tapestry of this fanfiction genre.
The theme of growth is also prevalent. Both characters grow in different ways. Harley might grow out of her co - dependence on the Joker with Ivy's help, and Ivy might become more open - minded and less isolated. There's also often a theme of adventure, where they go on various escapades together, facing villains and challenges side by side, which further cements their bond.
A common theme is friendship. Their unique bond, whether it's a platonic or a more romantic - leaning one, is often explored. It shows how they support each other through Gotham's chaos.
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.
In a fanfiction where Poison Ivy and Harley Quinn are married, their life could be full of adventure. They might use their combined skills to take over Gotham's underworld in a more 'eco - friendly' way. Ivy could use her plant powers to create barriers and traps, while Harley with her acrobatic skills and unpredictable nature could be the distraction. Their relationship would be a blend of passion and chaos, constantly keeping each other on their toes.
