DC Universe: After the Fall
"It took your God seven whole days to create his paradise. Let us see if I can do better."
Botanist Pamela Isley was transformed by a science experiment gone horribly wrong into a plant-human hybrid. With chlorophyll flowing through her veins instead of blood, she developed a toxic touch and a pheromone-fueled talent for seduction. Her increasingly plantlike nature drew her away from the parts of her that were human, and she slowly became more and more obsessed with protecting nature from the ravages of mankind. However, her distance from humanity turned rapidly into hatred, and her callous disregard for human life combined with her unique brand of eco-terrorism often put her into conflict with the Batman.
Usually unconcerned with the political scheming and machinations of Gotham’s resident crime lords, Poison Ivy has recently taken a more active part on Gotham’s stage. With the absence of the Dark Knight, nobody seems to have the iron will necessary to combat her powerful allure, and she has gathered an increasingly widespread area of control in Gotham.
Some suspect that this sudden change in behavior was triggered by the death of Harley Quinn, who was one of the few people with whom Ivy shared a genuine bond. Whether her recent activities are driven by a thirst for vengeance against the Red Hood for killing Quinn, or if the deranged protege of the Joker was Ivy’s last link to her dwindling humanity, one thing is for certain – any vestige of her former human self is truly gone. Poison Ivy is not human, and views the entirety of mankind as a threat that she believes must be pruned for the good of the world.
