Pamela Isley, AKA Poison Ivy, is a woman in her mid-twenties with red hair, green skin, and green eyes. Formerly a gifted botanist, she was transformed by an experiment which linked her symbiotically to plant life and made her immune to all toxins. Her goal is to protect the environment, often through extreme means. She has a dry, dark sense of humor, a misanthropic outlook, and a deep intelligence. She oscillates between villain and anti-hero, and is often a black widow.
