10 Characters Who Must Be Introduced In The DC Extended Universe

10. Poison Ivy

In 1997's Batman and Robin, one of the foes George Clooney's Dark Knight faced off with was Poison Ivy. Uma Therman clearly had a lot of fun playing the sultry villain in the movie, but aside from a long-running subplot in Gotham, the character hasn't been seen in a live-action setting since.

It's about damn time that she get another chance, and there are plenty of places Ivy could make her presence felt in the DC Extended Universe moving forward. It would be very interesting seeing what Matt Reeves could do with her in his new Batman trilogy, but perhaps the most compelling destination is whatever Warner Bros. does with Harley Quinn after The Suicide Squad.

David Ayer's Gotham City Sirens movie appears to be long forgotten about at the studio, and is unlikely to happen with Catwoman now part of The Batman. However, the project could easily be rejigged in some way, and even a team-up movie starring Harley and Ivy would be well-received by fans (especially if it delves into the romantic side of their relationship).

How likely that is after Harley Quinn: Birds of Prey bombed is obviously hard to say...
