She appears as one of the two secondary antagonists (alongside Harley Quinn) of Batman: Arkham Asylum, as the secondary antagonist of Batman: Arkham City's Catwoman Episodes, and as a minor antagonist-turned-supporting anti-heroine in Batman: Arkham Knight, as well as the deuteragonist of it's prequel DLC episode Harley Quinn.

Poison Iy intended to protect plants and trees from all over the world and as we saw in the first two chapters, she would do anything to protect them, even killing innocent citizens.
In Batman: Arkham Knight, she starts as a minor antagonist, but soon, she will join Batman to defeat the Scarecrow and to protect plants from Gotham, finally, Poison Ivy will sacrifice herself to cleanse the city of the Scarecrow's toxin.
