While she has always been closest to her plants, Poison Ivy has been known to form alliances with another one of Gotham City’s most notorious female felons, Harley Quinn, who bonded with the green goddess over their mutual experiences suffering abuse from their romantic partners.
There is no telling when Harley and Ivy’s friendship will hit live action cinema in the long awaited Gotham City Sirens movie, but at least we can confirm that Harley Quinn actress Margot Robbie is interested in exploring that relationship at some point.
The characters’ friendship in the comics has also endured in DC movies (such as 2017’s animated Batman and Harley Quinn) as well as TV shows like the popular animated HBO Max exclusive series Harley Quinn, which sees Kaley Cuoco and Lake Bell’s iterations fall into a romance that will be explored further in the upcoming third season.
