Batman villain info: Posion Ivy

PAMELA ISLEY aka POISON IVY

Poison Ivy (Pamela Lillian Isley) is a fictional character, a DC Comics supervillainess who is primarily an enemy of Batman. Created by Robert Kanigher and Sheldon Moldoff, she first appeared in Batman #181 (June 1966).
Poison Ivy is depicted as one of the world's most prominent eco-terrorists. She is obsessed with plants, botany, and environmentalism. She uses toxins from plants and her own bloodstream for her criminal activities, which are usually aimed at protecting the natural environment. She creates love potions that ensnare Batman, Superman, and other strong-willed individuals. Fellow villain Harley Quinn is her recurring partner-in-crime and possibly her only human friend.

Origins

Pamela Isley groew up wealthy with emotionally distant parents. Having earned top grades for most of her subjects (biology in particular) in her high school and college days, Pamela later studied advanced botanical biochemistry at a university with her boyfriend Alec Holland under Dr. Jason Woodrue. Isley, a timid, shrinking violet, was easily seduced by her professor. Woodrue injected Isley with poisons and toxins as an experiment, causing her transformation. She nearly died twice as a result from these poisonings, driving her insane. Later Woodrue fled from the authorities, leaving Isley in the hospital for six months. Enraged at the betrayal, she suffered from violent mood swings, being sweet one moment and like poison the next. When her boyfriend Alec got killed in a car accident after mysteriously suffering from a massive fungal overgrowth, Isley dropped out of school and leaves Seattle, eventually settling in Gotham City.
She began her criminal career by threatening to release her suffocating spores into the air unless the city met her demands. Batman, who appeared in Gotham that very same year, thwarted her scheme, and she was incarcerated in Arkham Asylum. From this point on, she had a kind of obsession with Batman, he being the only person she could not control. Over the years, she developed plant-like superpowers, the most noticeable being a lethal toxin in her lips; she is able to literally kill with a kiss.
In subsequent issues, she stated that she only started a life of crime to attain sufficient funds to find a location to be alone with her plants, undisturbed by humanity. A few years later, she attempted to leave Gotham forever, escaping Arkham to settle on a desert island in the Caribbean. She transforms the barren wasteland into a second Eden, and is, for the first time in her life, happy. It is soon firebombed, however, when an American-owned corporation tested their weapons systems out on what they think is an abandoned island. Ivy returned to Gotham with a vengeance, punishing those responsible. After being willingly apprehended by Batman, she resolved that she can never leave Gotham, at least not until the world was safe for plants. From then on, she dedicated herself to the impossible mission of "purifying" Gotham.

Analysis on Criminal Insanity

The dangerous experiments placed a deliberate overdose of plant and animal based toxins into her blood stream that make her touch deadly and allowed her to boost her immunity to all poisons, viruses, bacteria, and fungi. This immunity also includes Joker venom. Some comics have even gone so far as to depict her as more plant than human, breathing carbon dioxide and requiring sunlight to survive.
Ivy is known to be able to seduce men and women alike, often using pheromones to do so; she is even able to use these to control Superman, although she requires kryptonite for them to work.
She specializes in hybrids and can create the most potent toxins in Gotham City. Often these toxins are secreted from her lips and administered by a kiss. They come in a number of varieties, from mind-controlling drugs to instantly fatal necrotics.
In some adaptations, she can control plants with her mind. For example, while in Arkham, she is able to manipulate and animate plants, using roots to form supports for a tunnel she and another inmate named Magpie are digging to escape, and also spawning glowing fungi to entertain Magpie.
Poison Ivy is identified by the Swamp Thing as a being with an elemental mystical component, whom he calls the 'May Queen'. Writers have not referred to her in this way in quite some time.
In Batman: The Animated Series, her only physical power is an immunity to poison, and when using a poisoned kiss, she uses lipstick poisoned by toxins extracted from a plant. She admits to having a "hyperactive immune system" which prevents her from having children. In The Batman, she can even exhale mind-controlling spores in the form of a blown kiss.

Portrayal on Film

Uma Thurman played Poison Ivy in the film Batman & Robin. In the movie, Pamela Isley is shown researching in a South American lab, where she discovers the theft of certain plant toxins from her lab. Investigating, she discovers her boss, Dr Jason Woodrue, offering up Bane, a soldier enhanced by Venom, a toxin-derived chemical, to various bidders. Bane lashes out, and Isley is revealed in the fracas. Woodrue asks her to join him, but when she declines, he kills her by throwing her into a shelf full of chemicals (including a canister labeled Venom, the same drug that creates Bane). Isley rises moments later, having been infused with the plant chemicals that she was thrown into. She kills Woodrue with a poisonous kiss and escapes the burning camp with Bane.
Soon after, she appears in Gotham using both identities, Isley and Ivy, sparking friction between Batman and Robin — Robin proving more susceptible to her pheromones than Batman and thus becoming easily jealous — and breaks the recently imprisoned Mr. Freeze out of Arkham to form an alliance. Believing she is the dominant woman, she unplugs his wife's life-support system and claims that Batman did it, using this to encourage Freeze to begin a plan to freeze the entire Earth and then replace human life with her mutated plants, the two of them serving as the rulers. However, although Ivy manages to capture Batman and Robin with her plants, she is defeated easily by the new Batgirl, and her deception was subsequently being revealed to Freeze by Batman after the final showdown. Later Ivy is seen plucking petals off a flower in Arkham, pondering on whether Freeze truly loves her or not, when Freeze enters the cell and tells her that he is her new cellmate, and that he has personally sworn to make her life "a living hell" for nearly killing his wife.
