Poison Ivy AKA Pamela Isley is an enemy of the Dynamic Duo who appears in the Batman 66'.
Description[]
The Isley Family was a family of successful botanists who came to Gotham when Pamela was just a girl. Pamela's father Dr. Isley worked at the Gotham University and his nursery garden helped Gotham Flourish with plant life. Dr. Isley died when a mislabeled plant poisoned him and the University made no attempt at creating an antidote. Blaming Gotham University for her father's death, Pamela fled Gotham.
Years later, Pamela came back to Gotham with her own specially-designed monster-like plants and having put herself through a process which made her immune to every poison known to man. Pamela used her plants and powers to cause crimes in Gotham, having even apparently murdered flower-eater Louie the Lilac.
