Over the weekend, new character portraits debuted, featuring some of your favorite characters from Fox's Gotham which returns for Season 3 this fall. One character was notably absent, Ivy Pepper, a.k.a. Poison Ivy, because, as we've previously reported, that character has been recast, with Maggie Geha taking over the role from Clare Foley. Today we have our first look at Maggie Geha as the grown-up Ivy Pepper, along with new details that explain her new appearance, and details about two Suicide Squad characters coming to the series, Harley Quinn and Killer Croc.

Gotham executive producers John Stephens and Ken Woodruff revealed at Fox's TCA panel that the Indian Hill facility, the black ops program of Wayne Enterprises, will produce at least two characters featured on the big screen this weekend in Suicide Squad, Harley Quinn and Killer Croc. Of course, they'll be much younger versions of these characters, but executive producer Ken Woodruff teased that Indian Hill is how many of these villains will be introduced, although that might not necessarily happen in Season 3. Here's what he had to say below.

"The Indian Hill that exists in Gotham, that's the bridge to these villains like killer Croc and Solomon Grundy."

In the first season, fans were introduced to a character named Jerome (Cameron Monaghan), who most assumed was The Joker himself. As it turned out, Jerome was eventually killed in Season 2, and it was teased that this eccentric character will serve as a "forerunner" to the actual Joker down the line. Here's what executive producer John Stephens had to say about continuing to develop The Joker story through multiple seasons.

"It's about developing the myth of the Joker, just like we're developing the myth of Batman. It's so we can stretch him over multiple seasons. The cult of The Joker began, and we'll explore how that deepens and changes this year. There are underground movements where they talk about Jerome."

As for Poison Ivy, she only appeared sporadically, often appearing with her street-wise friend Selina Kyle a.k.a. Catwoman (Camren Bicondova). Two months ago, a report surfaced that Clare Foley will not return to the show, with the producers set to showcase Ivy Pepper's full transformation into Poison Ivy, who will be portrayed as an eco-terrorist. TV Insider has the first look at the new Poison Ivy, revealing that her sudden growth spurt will be "triggered by a run-in with an escaped monster from Indian Hill."

Of course, Indian Hill is where the nefarious Hugo Strange conducted his bizarre experiments. These experiments resulted in the return of formerly-dead villains such as Theo Galavan (James Frain), Mr. Freeze (guest star Nathan Darrow) and Fish Mooney (guest star Jada Pinkett Smith). We're not entirely sure how this unnamed monster triggers Ivy's growth spurt, or how her new look will change her relationships with Bruce Wayne (David Mazouz) and Selina Kyle.

Last season, Bruce Wayne, with the help of his trusted butler and mentor, Alfred Pennyworth, and his ally at Wayne Enterprises, Lucius Fox, found out there are more secrets to uncover regarding the Waynes' murders. Heading into Season Three, Gotham will continue to follow the evolving stories of the city's most malevolent villains: The Penguin; Edward Nygma/The Riddler; Selina Kyle/the future Catwoman; and Barbara Kean. Gotham also will dive into the origin stories of The Mad Hatter and the Tweed Brothers, and will peel back the curtain on the Court of Owls. While we wait for more on Season 3 of Gotham, take a look at this photo of the new Poison Ivy below.
