Pamela Isley: 1976 - 2005

Pamela Isley was brought up in a home of well-mannered, wealthy academics. At a young age, Pamela became fascinated by gardening and would spend hours at a time with her mother in the family greenhouses, producing award-winning specimens. As she grew older and began to understand the work her father did in pharmaceutical development, she became fascinated with helping people through selected breeding of plants to produce all manner of cures. This fascination became her life’s work and into her university studies, she began experimenting on plants using cutting-edge science to produce results that far surpassed that which was capable through typical gardening.

After attaining her doctorates degrees, Pamela worked at Arkham Asylum as an intern and later as a resident in pharmacy. She is also responsible for the creation of the Botanical Gardens which has remained an iconic part of the Arkham facility and been a core part of many patients’ therapy and rehabilitation efforts. After the creation of the Botanical Gardens, Pamela was recruited by Bruce Wayne to work in research and development department of Wayne Enterprises.

After the termination of Nygma, Isley’s department suffered significant cutbacks in funding during the restructuring of Wayne Enterprises. Instead of requesting additional funding due to her meek and timid personality, Dr. Isley focused on a single project: the development of a natural neurotoxin derived from plants. After prolong exposure to the fumes of the neurotoxins, Isley shed her cautions personality and became a sultry and bold femme fatale. Donning lipstick made from the same toxins, she attempted to seduce Bruce Wayne to further fund her project. Bruce denies she was successful, Pamela says otherwise. In any attempt, Bruce came to his senses at some point and terminated her employment. Frustrated, Isley returned to her lab in a fit of rage and injected herself with the untreated toxins.[1]

Poison Ivy: 2005 - Present

Upon injecting herself with the untreated plant toxins, Pamela Isley went into convulsions. She was rushed to a nearby hospital by ambulance. While passing Robinson Park en route to the hospital, the ambulance was stopped by a blockade of trees and shrubbery. Vines wrapped around the vehicle and the paramedics barely had time to escape being consumed by the mass of plant matter. The crushed vehicle was projected out minutes later, while Pamela was kept contained in a pulsing cocoon that formed in the heart of Robinson Park.

When Batman responded with Robin (it was actually Jason's first real field mission), the metamorphosis was nearly complete and both Caped Crusaders were present for the rebirth of Pamela Isley, who emerged naked from her cocoon in a cloud of pink pollen. Now calling herself Poison Ivy, she wasted no time using her nakedness and and her new powers to her advantage to turn the Caped Crusaders against each other to buy her time to don her unique choice of apparel and flee the scene. By the time the boys regained their senses, Ivy was gone.

It would be weeks before Ivy would return to the spotlight. Her first true act of terror was a bank robbery spree, but that was short-lived. Her next foray into crime was an escape from Arkham and an attack on Mayor's Office after they announced plans to remove the oldest tree in Slaughter Swamp for fear its collapse was imminent and could damage property. And then, of course there was the time that she created plant doppelgangers of socialites and infiltrated Gotham high society. Who can forget that one?

Of course, Ivy's most notorious stint was teaming up with Harley Quinn and Catwoman in 2010 and founding the Gotham City Sirens. Though the three started their partnership as criminals, they stumbled into a path of semi-vigilante behavior. In late 2015, Selina left the Sirens and Ivy and Harley quickly fell back into their criminal ways and were captured. Pamela was recently paroled and she seems to be doing fine... but this wouldn't be the first time she seemed sincere in her reform.[2]

Trivia and Notes


  • Arkham's inhibitor collar lowers Ivy's chlorophyll levels, turning her skin from green to flesh colored. Since her powers are what corrected her vision, she also needs her glasses when she wears the collar.
  • When she first began reforming, she worked at a Big Belly Burger.[4]
  • Her criminal activity falls under GCPD jurisdiction.
  • When she's in Arkham she's housed in the General Population Area.
  • She created a species of human-plant hybrids called sporelings.
  • She gave Lucy Quinzel immunity to plant-based toxins.[5]


  • Poison Ivy's Patient number (#66181-M) is a nod to her first comic book appearance: Batman #181, in 1966.
  • Roy explains Harley's relationship with Ivy: Harley and Ivy are lovers. They're relationship is mostly sensual. They first met in 2010 when Joker was captured and Harley was not... and Poison Ivy came crashing one of Joker's hideouts that Harley was using to lay low. Ivy wanted something that Joker had once taken from her. After a brief scuffle between the two, the hideout was ruined and the police were on their way, so Ivy told Harley she could crash at her place. This is how the Gotham City Sirens started in Earth-27. They became lovers shortly after they started "working" with Selina. As I said, their relationship is mostly sensual, about making each other feel better when they are in each other's company. Harley gives Ivy a connection to humanity that she tries to ignore. Ivy gives Harley the passion and intimacy that she doesn't get with Joker. So, it's more friends with benefits than true love, but there is a bit of actual love in there, even if both don't quite realize that.
  • Replacing Gotham Elites with plants might be a nod to The Batman episode Fleurs du Mal.
  • Changing into Poison Ivy on the way to the hospital is a nod to The Batman episode Batgirl Begins, Part Two.
  • The sporelings might be a nod to Batman: The Animated Series episode House & Garden or Poison Ivy: Cycle of Life and Death comic.
