Poison Ivy (Prime Earth)

Poison Ivy (real Name: Pamela Isley) is a anti-heroine from DC Comics.

Early Life
Pamela Isley was born with a skin condition - an aversion to sunlight. Though the doctor had prescribed her a lotion to protect her, little Pamela's abusive father had forbade her from going outside at all. On one occasion, when her mother allowed her to play outside, he had angrily punched her in the face, giving her a black eye. As if nothing had happened, Pamela's mother stepped outside and began gardening. Seeing her daughter there, she explained that she liked gardening because the flowers listen to her, and sometimes, if she stays very quiet, they speak back to her. When Pamela had asked about the black eye, her mother had assured her it was nothing to worry about. The abuse continued. Every time he hit her, Pamela's father bought his wife's forgiveness with flowers, and her garden would grow. That was how Pamela learned that flowers could manipulate people. However, she also learned of human cruelty when her father murdered her mother, burying her under her own garden before being arrested.

In college, Pamela created designer drugs, doling pheromone pills out in order to study their effects. The University learned of her activities, and she was expelled and put in jail pending a criminal indictment. However, she had already used her pills to get the Dean under her thumb. Charges were dropped, and she graduated Summa Cum Laude. After graduating, Pamela visited her father in prison for the first time since the murder of her mother. He had stubbornly sat in silence, just staring at her and waiting for her to make the first move. After a time, she decided to do what made the most sense. She leapt up out of her seat and kissed him. By the next morning, he was dead, and the toxin used to kill him was untraceable.

The Dean secured Pamela an internship at Wayne Enterprises straight out of College at their R&D site just after the merger with Kane Chemical. She helped to develop pharmaceuticals and cosmetic applications, but she had greater aspirations.

The Zero Year
Pamela became a research assistant at Wayne Enterprises, helping a man named Dr. Paji create a project that would allow plants to grow at an incredibly advanced rate. During the event that would be dubbed "Zero Year" by Bruce Wayne, a terrorist known as the Riddler partnered with a scientist named Dr. Karl Helfern to steal Pamela's experiment. The Riddler turned off the power in Gotham City, turning the city into a savage cesspit. The villain then spread Pamela's project throughout the city, turning the once proud and advanced city of Gotham into a literal urban jungle because of the incredible plant growth. However, both the Riddler and Hellfern were defeated by the new hero known as the Batman, and Gotham City began a rebuilding process, getting rid of all the plants that Pamela's stolen research had caused.

Becoming Poison Ivy
With the city back to normal, Bruce Wayne came to look in on Pamela's division when she took the opportunity to present him with a business project that would cut his advertising division by 100%. In fact, she had used pheromones to get the meeting with him, and this was her proof that Wayne Enterprises could use pheromones to target clients, and modify their behaviour to the company's benefit. Wayne refused her pitch on the grounds that it amounted to brainwashing, and removed free choice from the equation. Ethically opposed to her idea, Bruce Wayne fired her on the spot, warning that his company owned any research she had done, so she would not be able to pitch her idea elsewhere.

Angrily, she had rushed past security to steal what she could of her work back, specifically a plant serum that she had made from all of her knowledge in botanical research, which she alone knew how to make. Unfortunately, in the process, she was doused with her own chemicals. The chemicals changed her, making her immune to poisons and viruses, giving her command over any plant, and connecting her inexorably to The Green as well as giving her immunity to poisons and viruses and innate control of pheromones. She became something of an eco-terrorist, using her abilities to strike back at those who struck.
