Batman:The Animated Series Wiki

"They can bury me in the ground as deep as they like, but I'll grow back..."
―Poison Ivy[src]

Dr. Pamela Lillian Isley was a botanist who led a secret life as the eco-terrorist Poison Ivy. In contrast to the majority of Batman's foes, Ivy had little interest in money or power, but instead was obsessed with preserving plant life, and taking revenge against those who she believed had harmed it. Her ruthless methods frequently landed her in Arkham Asylum.


Holding a PhD in botany from Gotham University, Pamela Isley was once employed at Chez Gerard, a cosmetics firm, as an examination chemist in charge of developing new fragrances. She also offered a weekly oration series at the university on rare and extinct plant species. She always attempted to protect plants from humans and saved a specimen of a rare flower before the land they grew on was used to build Stonegate Penitentiary.

Batman at the mercy of Poison Ivy

Later, she either met with District Attorney Harvey Dent, and the two began courting. Unknown to Dent, Isley regarded him as a "murderer" for his part in organizing the diggings of land for the future site of Stonegate Penitentiary. The dig had involved flattening a meadow of wildflowers, containing a rare wild rose that would have become extinct, had she not protected it prior. Suitably, she used an abstract from the rose to produce a rare and lethal toxin, which she transferred to Harvey via a deep kiss. Harvey fell into a coma and was not expected to survive.

As a personal acquaintance of Dent's, Bruce Wayne investigated the crime as Batman. Ascertaining the source of the toxin, Batman confronted Isley, who revealed her nom-de-crime, "Poison Ivy", at her conservatory sanctuary. In the subsequent skirmish, Batman seized the rose as a "hostage," forcing Ivy to surrender the remedy she had developed. Batman succeeded in saving Harvey's life, and Ivy was, ironically, imprisoned in Stonegate.[1]

Eternal Youth[]

Later on, after having either escaped or been released, Ivy opened an all-natural resort spa outside Gotham, using the alias "Dr. Daphne Demeter." The "Eternal Youth Spa" was the lure through which Ivy attracted rich business men and women guilty of certain ecological wrongdoings, and she "treated" them with plant-derived pollutants, which transmuted the people into plants themselves.

Dr. Daphne Demeter

Through an unlucky accident, a gluttonous Wayne Enterprises executive had made a deal with a South American business to level a section of the Amazon rain forest, before Wayne halted it. Ivy beset Wayne for his supposed part in the deal, and Alfred Pennyworth attended in Bruce's place at a free spa retreat. After Alfred vanished, Batman swiftly realised the doctor's real identity, and stopped Ivy's plans once more.[2]

After one more escape, she was arrested at the Stacked Deck Club, over a poker game with The Joker, The Penguin, and Two-Face. Before the game, she traded a few amused nostalgias with her "old flame," Harvey Dent (the amusement was entirely one-sided).[3]

Time passed, and Ivy had appeared to have reverted to a ordinary life. Released from Arkham Asylum, Isley moved away from Gotham City, wedded her therapist, and encompassed his two children as her own. In spite of strange plant-related happenings going on, Batman and Robin were incapable to link any link to Isley. Regrettably, Ivy had purely deceived them. Fashioning plant beasts to act as duplicates of her "family", Ivy had not only produced a genuine façade for her undertakings, but also made a small drone factory. Though Batman and Robin once again foiled her and her plans, Ivy yet again escaped. After failing to meet the mental necessities for rehabilitation, Ivy returned to Arkham and was present for the Trial of Batman. She acted as a juror and as a "witness", affirming towards Batman's connection in her creation as a villainess.

Harley and Ivy[]

Harley & Ivy

From a mere chance meeting during a heist at the Gotham Museum, sparked one of Poison Ivy's most distinctive interactions. Harley Quinn, freshly cast out of the Joker's gang, helped Ivy escape the Gotham Police. Though the characters of the two appeared utterly contradictory, their (somewhat) mutual objectives drew them together into a daunting duo. Harley appeared to thrive on the practice of an honestly caring partner, while Ivy appreciated Harley's streak of fun and inventiveness, though she was frustrated by Harley's steadfast dedication to "that psychotic creep," The Joker.

Not long after uniting, they took Gotham by storm with a crime spree. Labelled "The Queens of Crime", their actions went unstopped for a long time, even going so far as to mockingly challenge anyone that "no man could stop them". Regardless of his best efforts, Batman was unable to capture both damsels, and only after their home was destroyed by The Joker did they flee, where Ivy got hoisted by her petard as her jeer of "no man could stop her" was true in spirit and fact, being arrested by Renee Montoya.

During her detainment in Arkham Aslyum, she and the other patients staged a revolt, where Mad Hatter used his mind-control cards to render the staff docile and Joker "presided" over a mock trial where the villains accused Batman of being responsible for their problems. Ivy was seen as one of the "accusers" against the Dark Knight.

After a few months in Arkham, Poison Ivy managed to manipulate Steven Carlyle, her psychiatrist, into releasing her, after which she locked the man and replaced him with a plant creature she created using his DNA. Ivy then used the monster to commit crimes, while she feigned innocence in the public eye. Eventually, Ivy's crimes were uncovered by Batman, but she fled Gotham preemptively, knowing that Batman would capture her.

    Batman pays her a backhand compliment as a genius combined with a fanatic-a compliment she does not dispute.

Background Information[]

In Batman Adventures Vol. 2 #16, it is revealed that after leaving Gotham in "House & Garden", Ivy left a plant clone of herself to distract Batman and keep Harley company while she lived a normal life with Dr. Alec Holland. This retcon was never confirmed to have happened in the series.
