Poison Ivy (Arkhamverse)

Poison Ivy served as a major antagonist and boss in Arkham Asylum, and then a minor antagonist in Arkham City where she only appears in the DLC: Catwomen's story. She is a plan-human hybrid who controls Plants and has chlorophyll flowing through her veins instead of blood, she developed a toxic touch and a pheromone-fueled talent for seduction. Her sole goal in life is to eradicate Humanity in order to wipe the world clean of pollution to allow her plants to sieze control over it and her as their ruler.

In Arkham Asylum, Harley Quinn releases her from her cell, and then she is injected with the TITAN formula. Thus, having her plants more powerful, plants are then all around the Island causing destruction and deaths of thugs and security guards. Batman fights and defeats her in the Gardens, using his Explosive Gel to break her shield and cause the Plant she's controlling to fall, then causing the part of the gardens to crumble but Batman escapes to confront the Joker.

In Arkham City, she has control of one of the buildings with her Plants. Catwomen confronts her, defeats mind-controlled thugs and leaving them to die by her plants. Ivy gains the upperhand and gets her hanging with her plants, but Catwomen promises to look after the flowers inside Hugo Strange's vault. She does find the flowers but kills them in revenge of Ivy attacking her, but decides to blame Hugo if she encounters Ivy again.
