Poison Ivy is Gotham City's resident eco-terrorist. A unique human/plant hybrid, she cares only for her beloved plants and their ultimate dominion over the planet. Poison Ivy's once-human body has been chemically altered and can create any number of pheromones and toxins to entice or destroy.
Her unique bond with plants means she can swiftly generate new breeds or plant explosive seed pods on her enemies.
Pale, gangly and unremarkable, Pamela Isley was a shy botanist when she went to work for famed scientist Dr. Jason Woodrue. Hoping to create a human/plant hybrid, Woodrue experimented on Isley, creating the beautiful-but-deadly Poison Ivy. Now a physical beauty with chlorophyll instead of blood and capable of exuding various pheromones and natural toxins, Ivy began a criminal career to fund her cause as a champion for the world's diminishing flora species.
Her body can be seen lying to the right and just a short distance past Green Arrow's as the "Who do you Trust" trailer opens.
