In many of these stories, the power dynamic between Poison Ivy and the male reader is explored. Since she has her powers related to plants and toxins, it can create an interesting imbalance. Some stories also focus on the theme of love against all odds. Given Poison Ivy's villainous status in the DC universe, a relationship with a regular male character can be seen as something that goes against the norm. And, of course, there are themes related to the beauty and danger of nature, as Poison Ivy's character embodies both aspects and the male reader has to deal with that in their relationship.
A lot of these fanfictions play with the idea of the male reader being an 'outsider' who gets drawn into Poison Ivy's world. It could be because he accidentally stumbles upon her lair or has a chance encounter with her. Also, there's the theme of redemption or change. Maybe the male reader helps Poison Ivy see a different side of humanity, or she changes his perspective on nature and the world. There are often elements of mystery and adventure as well, as they navigate the world of Gotham together or deal with other villains.
Another theme could be the protection aspect. Given that Poison Ivy has her own set of enemies, the male reader may be portrayed as someone who protects her and their unborn child. This can add an element of action and drama to the story.
A common theme could be the exploration of a unique relationship dynamic. Given Poison Ivy's nature - loving and somewhat dangerous persona, there might be themes of the male reader being both attracted and cautious. Another theme could be the power play between the two characters, with Poison Ivy's powers and the male reader's own charm or skills coming into play.
A common theme is the OC helping Poison Ivy in her environmental crusades. Maybe the OC has some special skills or knowledge that aids Ivy. Another theme could be a romantic relationship developing between them, often with the OC being initially drawn to Ivy's passion for plants and the environment.
One common theme is the clash of ideologies. Robin stands for justice in the traditional sense, while Poison Ivy is more about environmental justice. Their different outlooks often create tension and drama in the stories.
Another theme is redemption. Sometimes the oc helps Poison Ivy to find a more positive path or a different way to fight for her beliefs. This can involve the oc showing her new ways to interact with society without causing harm while still standing up for nature.
Another theme could be environmental. Since Poison Ivy is very much associated with plants and the environment, and a Changeling might have some connection to the natural world as well. Fanfictions might explore how they team up to protect the environment or how their views on nature differ. This can involve complex relationships with other characters who might be harming or helping the environment.
Nature vs. technology is also a big theme. Poison Ivy is all about nature and its power, while Red Robin has access to high - tech gadgets. Fanfictions play with this contrast, like how Ivy's natural powers might disrupt Red Robin's technological plans or how his tech could be used to understand her better. It's really interesting to see how the two elements clash and merge in different stories. For example, in some fanfics, Red Robin has to use his gadgets to survive in Ivy's dangerous natural habitats.
The idea of environmentalism is also quite common. Since Poison Ivy has such a strong connection to plants, fanfictions may use her presence in the Harry Potter world to bring up issues about the care and protection of magical plants and the environment in general. For example, she might try to influence how the Herbology classes are taught or advocate for better treatment of the Forbidden Forest.
Another theme is the power dynamic. Given their different powers, there are fics that explore how they use their powers together or in relation to each other. Sometimes, they might combine their powers for a greater good, like using Poison Ivy's plants to create a habitat for the animals Beast Boy can transform into. There are also fics where their powers might clash, leading to some interesting conflicts within the story.
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.
