Pamela Lillian Isley, aka Poison Ivy, is a fictional supervillainess from DC Comics, serving as a recurrent enemy of Batman. She was a botanist and biochemist who turned into a misanthropic ecoterrorist.
She possesses absolute control over plant life, as well as poisonous touch and enhanced physical abilities. Empowered by an interplanetary force known as Green, Poison Ivy turned herself into a plant-human hybrid who uses her powers for the sole purposes of ecoterrorism. She was originally characterized as a villain but as of New 52 and DC Rebirth she turned into an antiheroine, actually serving as an often love interest for Harley Quinn.
