|~ Poison Ivy to Catwoman in Arkham City|

She is a plant-human hybrid who controls Plants and has chlorophyll flowing through her veins instead of blood, she developed a toxic touch and a pheromone-fueled talent for seduction. Her sole goal in life is to eradicate Humanity in order to wipe the world clean of pollution to allow her plants to seize control over it and her as their ruler.
Controlling Plants in Arkham Asylum
In Arkham Asylum, Harley Quinn releases her from her cell as a favor to her friend. Later on, Batman needed to find a cure for the TITAN formula and asked for Poison Ivy's assistance. At first Poison Ivy wanted nothing to do with helping Batman, so she tries to kill him. However, Batman grabbed one of Poison Ivy's beloved plants and crushed it. He threaten that he'll destroy every plant unless she help him with the cure. Ivy then told Batman that there's a plant that contains the spores needed to create a cure. But she also told him that the plants were in Killer Croc's lair. Before he left, Batman told Ivy to return to her cell, otherwise he'll come after her. Ivy then replied that she'll be waiting. As Batman was leaving the Gardens, Joker ended up injecting Ivy with the TITAN formula. The formula reacts differently with her unusual DNA, greatly enhancing her powers over plants. Having her plants grow more powerful, she causes them to grow up all around the Island causing destruction and deaths of thugs and security guards. After successfully creating a cure, Batman went back to the Gardens to stop Poison Ivy's Plants from getting too powerful and spreading to Gotham. As Batman made it to the Gardens, Batman was about to inject the formula into the main plant, however, Poison Ivy stopped him from doing so. She also explained that she thought that plants were in pain, but soon realizes that they were evolving. Ivy then summoned a large plant monster and used it to confront Batman. Batman managed to defeat her in the Gardens, using his Batarangs and Explosive Gel to break her shield and cause the Plant she's controlling to fall, then causing the part of the gardens to crumble but Batman escapes to confront the Joker. after the Joker was defeated, the police managed to find a weaken Poison Ivy, extract the TITAN Formula out of her, and place her back in her cell.
In Arkham City, she has control of one of the buildings with her Plants. Catwoman confronts her, defeats mind-controlled thugs and leaving them to die by her plants. Ivy gains the upper hand and gets her hanging with her plants, but Catwoman promises to look after the flowers inside Hugo Strange's vault. She does find the flowers but kills them in revenge of Ivy attacking her, but decides to blame Hugo if she encounters Ivy again.
