Pamela Lillian Isley was a young botanist poisoned by her professor as an experiment. She survived and while getting an immunity to toxins, Isley went insane and became Poison Ivy, an eco-terrorist out to save the environment in a deranged way. Unlike most Batman rogues, Ivy revolves her crimes around her obsession with plants and a twisted way of saving the environment.

Harley Quinn is a chief ally of hers in several of her schemes, her best friend.
