Poison Ivy is a plant-controlling super-villainess who frequently battles with the Dark Knight, Batman. She is also a longtime friend of Harley Quinn. She is a playable character in Injustice 2.
Dr. Pamela Isley was once an innovative but radical botanical biochemist with a singular goal: make the world safe for plant life to flourish. She joins the Society to further their common interest in bringing mankind to its knees, but at heart, Ivy’s desire is to ensure that in any new world order, flora dominates fauna.
