They could form an unlikely alliance. The kiss could be the catalyst for them to realize that they both want to protect the city in their own ways. Batman with his justice and Ivy with her love for nature. They start working together secretly, and their relationship evolves from that initial kiss into a deep bond of mutual respect, though still with some romantic tension that they struggle to deal with.
Well, it could turn into a love - hate relationship. After the kiss, Batman might be conflicted. He's attracted to Ivy but knows she's a criminal. So, he tries to keep her in check while also being drawn to her. Ivy, on the other hand, could see Batman as a challenge and keep trying to seduce him more, leading to a cat - and - mouse game with a romantic undertone.
After the kiss, Batman may try to find a cure for Ivy's criminal tendencies. He sees the good in her that was revealed during the kiss. Ivy, feeling something new for Batman, allows him to try. This process brings them closer as they spend time together. But there are always setbacks, like Ivy's powers getting out of control or Batman's enemies trying to use their relationship against them, which makes their relationship development full of twists and turns.
After the kiss, they could enter a sort of uneasy truce. Batman might be more hesitant to fight Poison Ivy directly as he's now aware of a different side of her. Poison Ivy, on the other hand, could start leaving clues for Batman instead of causing outright chaos, like she might target only the really bad polluters in Gotham and leave a calling card for Batman to find. This way, they start to work in a strange, unspoken partnership.
Their relationship can be portrayed as a complex battle of wills. Poison Ivy sees Batman as a symbol of the human world that she resents, yet she can't help but be attracted to his strength. Batman, on the other hand, views Poison Ivy as a dangerous criminal, but the kiss makes him question if there's more to her than just villainy. It could be shown as a push - and - pull dynamic, with moments of intense attraction and then sudden distrust.
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.
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.
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.
The relationship could be very complex. Batman would likely be cautious at first. He'd see the child as a potential threat due to being Poison Ivy's offspring. But if the child showed signs of good, Batman might start to mentor them. He could teach the child about using their powers responsibly, just like he does with other young heroes or sidekicks. He might also be protective of the child in a way, trying to keep them away from Ivy's more dangerous influence.
In some fanfiction, it starts with a chance encounter. Maybe Batman is investigating a crime related to Ivy's plants, and he sees a different side of her. This initial meeting plants the seed (no pun intended) for their relationship. Then, as they interact more, they start to understand each other's motives better. For example, Batman realizes that Ivy's actions, although extreme at times, are rooted in her love for nature.
In a fanfiction scenario, the kiss between Batman and Poison Ivy might occur during a tense moment. Maybe Batman is trying to stop her from releasing a dangerous plant - based toxin, and in a moment of desperation, Poison Ivy grabs him and kisses him. This kiss could be a power play on her part, a way to try and disarm Batman both physically and mentally. However, Batman, being the strong - willed character he is, quickly regains his composure and continues his fight against her evil plans.
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.
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.
