A possible start could be that the Oracle at Camp Half - Blood gives Percy a prophecy that involves a 'green - haired woman with the power of the plants'. Percy doesn't understand it at first, but then while on a mission in a big city, he sees Poison Ivy in action. He decides to follow her and see what she's up to. Poison Ivy notices him following her and tries to lose him. This cat - and - mouse chase in the city streets could be the opening sequence of the fanfiction, leading to their first real encounter and the start of their intertwined story.
It could start with Percy feeling a strange disturbance in nature while he's near a forest. As he investigates, he comes across Poison Ivy who is tending to her plants. She immediately attacks him, thinking he's there to harm her precious greenery. Percy has to quickly defend himself and tries to explain that he's just there because he sensed something off in nature. This encounter sets the stage for their further interactions, whether they become friends or foes.
The story might begin with Poison Ivy being magically transported to Camp Half - Blood. The demigods are all on high alert as they've never seen a being like her before. Percy steps forward to communicate with her. He's initially cautious but also curious. Poison Ivy is disoriented and angry at being in this strange new place. She starts to use her powers to create a protective barrier of plants around herself, and Percy has to find a way to break through that barrier, both physically and metaphorically, to start a conversation with her.
In this fanfiction, the gods in Percy Jackson's world are intrigued by Poison Ivy's power. They bring her to Olympus to study her. Percy is assigned to be her guide while she's there. Along the way, they discover that there are similarities between the magic in Poison Ivy's world and the divine powers in Percy's world. They start to experiment with combining their powers, like Percy using his water powers to help Poison Ivy's plants grow in unexpected ways, and Poison Ivy using her plants to create shields for Percy during his training sessions.
The fanfiction could start with Poison Ivy being magically transported to the wizarding world. She finds herself in the Forbidden Forest and starts to spread her influence among the native plants there. Harry Potter, while on a patrol in the forest, notices the strange changes in the plants and is the first to encounter Poison Ivy, leading to a tense first meeting between the two.
Spiderman could try to reason with Poison Ivy. He might say that her actions of using plants to attack are harming innocent people. For example, when she makes vines wrap around buildings, it could endanger those inside. He would appeal to her sense of justice and ask her to find a more peaceful way to promote plant growth.
Well, in some fanfictions, Percy might use his water - controlling abilities. Since poison can be in liquid form, he could manipulate the water within the poison, perhaps separating out the harmful components. Another way could be through his demigod powers, which might give him an innate resistance or control over harmful substances like poison.
First, you need to study the characters. Know their personalities, powers, and backstories. For Swamp Thing, understand his connection to the swamp and his role as a defender of nature. For Poison Ivy, focus on her love for plants and her somewhat anti - human stance at times.
Naruto would likely have to get used to living among plants. He might start to learn how to communicate with them, just like Poison Ivy does. For example, he could learn to sense when a plant needs water or is under threat. He would also have to adapt to her more anti - social tendencies towards humans, which could be a real struggle for Naruto, who values human connections.
The relationship would change drastically. Batman, who was once her enemy, would become her partner. They would start to share their secrets and work together towards common goals. For example, Batman might use his detective skills to help Poison Ivy target the real polluters in Gotham, while she could use her plant - based powers to help him in his fight against other villains.
Some writers portray Poison Ivy as a pure villain. They focus on her using her plant powers to cause chaos in Gotham, like creating giant vines to strangle buildings or using poisonous plants to attack people. Other writers show her as an anti - hero. In these portrayals, she's fighting for the environment, and her actions against Gotham are seen as a form of protest against the city's pollution and destruction of nature. She might only target those who are harming the environment.
She can be shown to have a backstory that justifies her actions. For example, if she was once a scientist trying to save the environment but was shunned by the establishment, which led her to use more extreme methods. This would make her not just a simple villain but a character with depth. Also, showing her moments of vulnerability, like when her plants are in danger or when she actually cares about the well - being of the people in Gotham despite her methods, would add complexity.
I once went camping and unknowingly walked right through a patch of poison ivy. At first, I didn't realize what had happened. But a few hours later, my skin started to itch like crazy. It spread all over my legs and arms. I had to rush to the nearest store to get some anti - itch cream. It was a horrible experience but also a memorable 'poison ivy story' for sure.
