Poison Ivy (character) in the context of "The New 52"

The Batman family enemies are a collection of supervillains appearing in American comic books published by DC Comics. These characters are depicted as adversaries of the superhero Batman and his allies.

Since Batman first appeared in Detective Comics #27 (May 1939), his supporting cast has expanded to include other superheroes, and has become what is now called the "Bat-family". As with most superheroes, a cast of recurring enemies to the Batman family have been introduced throughout the years, collectively referred to as Batman's "rogues gallery". Many characters from Batman's rogues gallery who are criminally insane become patients at Arkham Asylum after they are apprehended.

Sheldon "Shelly" Moldoff (/ˈmoʊldɒf/; April 14, 1920 – February 29, 2012) was an American comics artist best known for his early work on the DC Comics characters Hawkman and Hawkgirl, and as one of Bob Kane's primary "ghost artists" (uncredited collaborators) on the superhero Batman. He co-created the Batman supervillains Poison Ivy, Mr. Freeze, the second Clayface, and Bat-Mite, as well as the original heroes Bat-Girl, Batwoman, and Ace the Bat-Hound. Moldoff is the sole creator of the Black Pirate.
