Poison Ivy is a female college student who loves plants. She was deceived by botanist Jason Wood and injected with phytotoxins. Pamela survived, but all her blood turned to chlorophyll. At this point, Pamela lost her fertility. She killed Jason Wood who cheated her and took her favorite plant to a desert island. Later, in a military exercise, a Russian missile reduced everything on the island to ashes, and Pamela's anger ignited. As a natural avenger, she declared war on Batman and Gotham as a whole. Poisonous vines can secrete deadly venom from her lips and poison her target. Her mental toxin even controlled Superman, which triggered the war between Superman and Batman. Only a determined man like Batman can resist the poison of poison ivy.

Poison vine is the most vicious female character in Batman. Although he is not good at fighting, he has a first-class mind. Ivy first appeared in 1966, the creator was Robertson Singh, and the costume was designed by Kami Fanteno. This model has been used to this day and has hardly changed. According to the setting in her personal monograph, Pamela was originally an innocent female college student in the Department of Botany who loved flowers and plants. She was deceived by professor Dr. Jason Wood in a study of poisonous plants and participated in human experiments. The ignorant Pamela was then injected with a chemically synthesized phytotoxin.

Pamela, who was dying, was lucky enough to survive. The toxin spread to her body cells, causing her cells to mutate, making her immune to all toxins, bacteria and molds, but at the same time becoming infertile. Moreover, her body can release strong toxins, including strong hormones, which can poison any object and attract any man or woman.

But at first, she was not so vicious except for killing the doctor who betrayed and cheated her. Pamela, betrayed by a trusted person, is disappointed with human nature, so she hates men and knows that she can't live a normal life after mutation. Pamela took her beloved plants and settled on an uninhabited island. It was not until one day that the Russian army test-fired the Vulcan missile "Prometheus" and turned the island into a scorched earth that the angry Pamela returned to gotham city as a natural avenger. After the "Flash Point" incident, DC comics were completely restarted, and many characters had a new position, poison rattan being one of them. Now, she has joined the Raptor Team formed by Bat Girl Barbara, to compete with the mysterious evil forces in Gotham.
