Poison Ivy (Pamela Lillian Isley) is a fictional character, a DC Comics supervillainess who is primarily an enemy of Batman. Created by Robert Kanigher and Sheldon Moldoff, she first appeared in Batman #181 (June 1966).
Poison Ivy is depicted as one of the world's most prominent eco-terrorists. She is obsessed with plants, botany, and environmentalism. She uses toxins from plants and her own bloodstream for her criminal activities, which are usually aimed at protecting the natural environment. She creates love potions that ensnare Batman, Superman, and other strong-willed individuals. Fellow villain Harley Quinn is her recurring partner-in-crime and possibly her only human friend.
