Poison Ivy is finally set to make her entrance in the Arrowverse with an upcoming appearance in Batwoman season 3. After her introduction was teased in the season 2 finale, it's been announced that Bridget Regan will debut as Poison Ivy in the next season in a recurring guest star role. Regan is perhaps best known to superhero fiction fans for her role on ABC's Agent Carter, though she's also appeared on shows like The Last Ship, Jane the Virgin, and White Collar.

Batwoman's incarnation of Poison Ivy in the ArrowVerse is as a "former botany student of Gotham University described as a passionate, brilliant scientist with a mind for changing the world for the better. But her plans shifted when she was experimented on by a colleague, injected with various plant toxins which turned her into the infamous Batman villain Poison Ivy. With a formidable power coursing through her veins, Pamela used her powers to do what she thought was right, even if Batman and those closest to her disagreed with her dangerous methods. Now effectively wiped off the board for years, Batwoman and the Bat Team must prepare themselves for Poison Ivy to return with a vengeance."

As one of Batman's most popular foes, Poison Ivy has frequently appeared in different animated DC projects. These days, she is voiced by Lake Bell on the HBO Max series Harley Quinn. There have been a handful of live-action adaptations as well such as Uma Thurman playing Ivy in the Joel Schumacher movie Batman and Robin. On the Fox prequel series Gotham, the Ivy character was reimagined as a young woman who aged rapidly and had three different performers in the role: Clare Foley, Maggie Geha, and Peyton List. She hadn't appeared in the Arrowverse before now.

Another big fan of Poison Ivy is Margot Robbie, who's been trying hard to get the plant-loving supervillain back on the big screen as well. She has said how she's been lobbying Warner Bros. for Poison Ivy to come into a movie to further explore her relationship with Harley Quinn. A lot of people have even pitched Megan Fox playing that role after Fox said she wanted to join a superhero movie franchise.

"Trust me, I chew their ear off about it all the time," Margot Robbie recently told Den of Geek. "They must be sick of hearing it, but I'm like, 'Poison Ivy, Poison Ivy. Come on, let's do it.' I'm very keen to see a Harley-Poison Ivy relationship on screen. It'd be so fun. So I'll keep pestering them. Don't worry."

Batwoman premiered on the CW in 2019, originally with Ruby Rose in the lead role. The show picks up with Kate Kane (Rose) becoming the new savior of Gotham City after Batman/Bruce Wayne goes missing for years. Though Rose opted not to return as Kate Kane for season 2, the network pushed on with the show by bringing in Javicia Leslie as Ryan Wilder, the new lead character who dons the mask and cape. A third season was officially ordered by the CW in January. This news comes to us from Variety.
