Some writers depict their relationship as a love - hate dynamic. Batman is attracted to Poison Ivy's beauty and her passion for nature, yet he hates her criminal ways. For example, he might be constantly in a struggle between his feelings for her and his duty to stop her crimes.
Often, they show a relationship based on mutual respect. Even though they are on opposite sides, they recognize each other's intelligence. Batman respects Poison Ivy's knowledge of plants and her ability to use them as weapons. Poison Ivy respects Batman's detective skills and his unwavering commitment to protecting Gotham. This respect can sometimes lead to a sort of unspoken alliance in certain situations in the fanfiction.
One possible fanfic could be centered around Batman's encounters with Poison Ivy within the Arkham universe. Maybe it could explore their complex relationship, with Batman constantly trying to stop Ivy's environmental extremism while also seeing the good in her intentions at times. For example, Ivy might be trying to protect a particular area in Arkham City that she believes is crucial for nature, and Batman has to find a way to balance the law and her motives.
There are fanfictions that explore Poison Ivy's backstory in the Arkham Knight world more deeply. For example, a story might focus on her early days and how she came to have such a strong connection with plants. This can add a lot of depth to her character in the context of the game's lore.
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.
A possible fanfiction could focus on a team - up between Poison Ivy and another Arkham character, like Catwoman. They could form an unlikely alliance to take on a common enemy in Arkham City. The story could show their different motives and how they manage to work together despite their differences. For example, Ivy wants to protect the natural environment of Arkham City which is being destroyed by a new construction project, while Catwoman is more interested in the valuable artifacts hidden in the buildings.
One common plot twist could be Poison Ivy using her powers in a new and unexpected way to either help or hinder Batman. For example, she might be able to control a new type of plant that has properties that can nullify Batman's gadgets. Another could be a situation where Batman has to make a difficult choice between saving Gotham and saving Poison Ivy from some greater threat. This would put his moral code to the test as he has always seen her as a villain but may have developed some complex feelings in the context of the fanfic.
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.
Poison Ivy can also be a character of redemption in some fanfic. Maybe she realizes that her extreme methods are not the best way to protect the environment. She could then start to work with Batman or other characters to find more sustainable solutions. This would be a different take on her character and could lead to some really interesting story arcs in the fanfic world.
By exploring their similarities. Both are outcasts in a way. Batman is an outcast from normal society because of his vigilante ways, and Poison Ivy is an outcast because of her connection to plants. A fanfic could delve into how they find common ground in their isolation, which gradually turns into a more complex relationship.
A plot idea could be that Poison Ivy creates a new type of plant - based virus in Arkham that only affects humans who are harming the environment. Batman has to find a way to stop the virus from spreading while also dealing with Ivy's strong beliefs. Another idea is that Ivy discovers a rare plant in Arkham that she believes can save the planet, but it's in a highly guarded and dangerous area. Batman and Ivy might have to work together to retrieve it.
