Poison Ivy (Maggie Geha) will return as a “dangerous” woman in “Gotham” Season 4. Fox

Poison Ivy (Maggie Geha) is fed up with being treated like a little girl and an outcast, so this Season 4 of “Gotham,” she took matters into her own hands by ingesting poison that would make her powerful.

“Gotham” co-executive producer Bryan Wynbrandt told SYFY WIRE that this decision is going to transform Ivy into her comic book counterpart, which is the dangerous plant-controlling and poison-oozing villain.

“This is indeed going to be a major shift in Ivy’s character. She’s at a crossroads, fed up with Penguin, alienated by the Sirens. So it felt like the perfect time to push the character in a new direction,” Wynbrandt said.

Unfortunately, Wynbrandt said Ivy in the Fox show would have to take a backseat for now, because “she’s going to go away for a little while.” But when she comes back, Wynbrandt said it’s going to be worth the wait.

“When she comes back later in the season we will see her transformed or ‘becoming’ more of the Ivy we know from the comics. Dangerous. A live wire of crazy energy,” he said. “‘Becoming’ or ‘transformation’ is a core thematic element running through the entire season. One of the things we love about our show and our great cast is that we can constantly evolve their characters in interesting and dynamic ways.”

Another character who has transformed significantly since Season 1 is Barbara Kean (Erin Richards). She went from being Jim Gordon’s (Ben McKenzie) fiancee to spurned lover then villain, and this Season 4, there’s a chance for her to become good again.

“It’s been so interesting, and I feel like she has so much potential, as in she could end anywhere,” Richards told Bustle. “She could go back to good, she could go back to bad. I think the great thing about a character like Barbara is that we actually don’t know the end of her.”

However, co-executive producer John Stephens said she would have to get the better of Ra’s Al Ghul (Alexander Siddig) first, if she chooses to go back to being good. It was Ra’s Al Ghul who resurrected her from the dead and supplied her with her new ammunitions business. His benevolent act surely won’t go unpaid.

“There will be elements of that connection to Ra’s al Ghul that will inform her personality going forward in her arc,” Stephens told Comic Book.

“Gotham” Season 4 airs Thursdays at 8 p.m. EDT on Fox.
