Supergirl's friends, like the other members of the Justice League, would be very concerned. They know Poison Ivy's reputation. When they find out about the kiss, they would be worried that Supergirl has been compromised. They might start investigating immediately, trying to figure out what Poison Ivy's motives are and how to protect Supergirl from any potential harm.
Well, one possibility could be that Poison Ivy, with her allure and plant - based powers, somehow crosses paths with Supergirl. Maybe she kisses Supergirl as a form of manipulation. She could be trying to use Supergirl's powers for her own environmental - protection - gone - wrong schemes. For example, she might want Supergirl to help her spread some kind of plant that could overtake a city, thinking it would make the world more 'green' but in reality would be a disaster.
It's hard to say exactly what would happen. But it might cause a rift between heroes or trigger a series of events that shake up the Comic Vine universe.
One great Poison Ivy x Supergirl fanfiction is 'Green Allies'. It explores an alternate universe where they team up to save the world from an environmental disaster caused by a powerful villain. The story beautifully weaves their powers together and shows how their different personalities can complement each other.
There are definitely some interesting ones. Some fanfictions might explore a more romantic side of their encounter, while others could be more about Poison Ivy using her kisses for her own devious plans against Robin. It really depends on what kind of story you're looking for.
Robin would be extremely worried and confused. He would immediately start investigating what happened to Batman. He might suspect Poison Ivy right away and try to find her lair to break the hypnosis. Alfred, on the other hand, would be more cautious. He'd try to keep Batman's identity a secret while also trying to find a way to bring him back to normal, perhaps using some of his own scientific knowledge.
Their powers also play a big part. Supergirl has super strength, flight, heat vision etc. Poison Ivy can control plants. In fanfiction, writers can come up with really creative ways for them to use their powers in combination. For example, they could use Ivy's plants to trap villains while Supergirl uses her strength to move them to a secure location. It allows for a lot of action - packed and imaginative scenarios.
One popular theme could be the struggle between Poison Ivy's environmental motives and her feelings for Batman. For example, in some fanfictions, her kisses might be a way to manipulate Batman into helping her with her ecological plans. Another theme could be the forbidden love aspect. Since they are on opposite sides in the Batman universe, their relationship is full of tension and the idea of a kiss adds to that allure. Also, the idea of Poison Ivy using her powers during the kiss, like her pheromones, to influence Batman's actions or his perception of her is quite common.
One plot idea could be that Poison Ivy kisses Robin as part of a trap. She might be trying to manipulate him into doing something for her, like stealing something from Batman or leading Batman into a dangerous situation.
It can introduce a new dynamic. In the Batman universe, Poison Ivy is a villain and Batman is a hero. A kiss between them blurs the lines. It might make Batman question his own judgment, especially if he has any feelings in return. This could lead to changes in how he approaches dealing with Poison Ivy in future encounters.
Well, initially, Poison Ivy would likely be hostile. She has her own agenda when it comes to nature, and Damian, coming from the Batman world, represents a different set of values. However, as she gets to know him, she might see that he's not just a mindless enforcer. Damian's respect for life in his own way, which he has learned from Batman and his own experiences, could make Poison Ivy re - evaluate her view of him. And perhaps, she could start to see him as an ally in some aspects, especially if they face a common threat to nature together.
