Poison Ivy is one of the most sultry of Batman villains. Poison Ivy: It's sad that Pamela Isley, or Poison Ivy, became the way she did because of experiments. While she was taking Biology, her professor seduced her and injected her with poisons and toxins. This caused Poison Ivy to transform into a plant-like menace to society. One of the Batman villains, Poison Ivy started out as a wealthy girl with parents who could care less. When she grew up, Poison Ivy dropped out of school after her boyfriend suddenly passed away. All of these events set the stage for Pamela Isley to transform into Poison Ivy. During this time, she moves to Gotham City from Seattle. She starts out by threatening the city with toxic spores unless they do what she wants. Thankfully Batman came to Gotham City that same year and was able to stop Poision Ivy's evil plot. She is one of the Batman villains that uses her potions to make other super heroes fall in love with her. Batman stops her from hurting the city, and Poison Ivy gets locked inside a mental institution for the criminally insane. Over the years, Poison Ivy's plant-like powers develop until she is super human. One of her weapons is the fact that her lips are poison, so she is the only one of the Batman villains who can literally give the kiss of death. Poison Ivy was brought into the picture when comic book readers started to sympathize and relate to Catwoman. They needed a new evil female Batman villain to take her place. Poison Ivy was the answer because it gave the readers a new female super villain to hate. Looking gorgeous with her flaming red hair and her skimpy outfit made of leaves, Poison Ivy is one of the best Batman villains of all time.
