Poison Ivy (Pamela Lillian Isley) is a fictional supervillainess appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. Created by Robert Kanigher and Sheldon Moldoff, the character made her first appearance in Batman #181 (June 1966).^[1] Poison Ivy is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.

Poison Ivy is depicted as one of the world's most notorious eco-terrorists. She is obsessed with plants, botany, ecological extinctionand environmentalism. She uses toxins from plants and mind-controlling pheromones for her criminal activities, which are usually aimed at protecting endangered species and the natural environment. Fellow villain Harley Quinn became her recurring partner-in-crime. She has proven to be one of Batman's more powerful foes, as she is one of the few members of his rogues gallery to display anything close to superpowers. The character has been portrayed as a love interest for Batman in some comics. In one comic, she was robbing a charity gala Bruce Wayne and Barry Allen were attending. Her first kiss was poison, the second its antidote. When they first meet, her toxic lips planted a seed of toxic rapture in Bruce. But when she later kissed a dying Dark Knight, she unknowingly cured her intended victim and established a budding romantic tension between them. - Wikipedia
