List of Batman Family adversaries in the context of "Penguin (character)"

Catwoman is a character appearing in American comic books published by DC Comics. Created by Bill Finger and Bob Kane, she debuted as "the Cat" in Batman #1 (spring 1940). She has become one of the superhero Batman's most prominent enemies, belonging to the collective of adversaries that make up his rogues gallery, as well as Batman's best known and most enduring love interest, with many stories depicting their complex love–hate relationship. Since 1993, Catwoman has had her own ongoing series, Catwoman.

Catwoman is the alter ego of Selina Kyle, a burglar in Gotham City who usually wears a skintight bodysuit and uses a bullwhip for a weapon. She was originally characterized as a supervillain and adversary of Batman, but has been featured in an eponymous series since the 1990s that portrays her as an antiheroine, often with a utilitarian moral philosophy. The character thrived in her earliest appearances, but she took an extended hiatus from September 1954 to November 1966 due to the developing Comics Code Authority in 1954. These issues involved the rules regarding the development and portrayal of female characters that were in violation of the Comics Code, a code which is no longer in use. In the comics, Holly Robinson and Eiko Hasigawa have both adopted the Catwoman identity, apart from Selina Kyle.

Poison Ivy is a character appearing in American comic books published by DC Comics. Created by writer Robert Kanigher, Sheldon Moldoff and artist Carmine Infantino, she debuted in Batman #181 (June 1966) and has become one of the superhero Batman's most enduring enemies belonging to the collective of adversaries that make up his rogues gallery.

In her comic book appearances, Poison Ivy is depicted as a doctor of botany-turned-misanthropic ecoterrorist in Gotham City named Pamela Lillian Isley, PhD (/ˈaɪzli/ EYEZ-lee) with the ability to control all plant life. Empowered by an elemental force known as the "Green", Ivy attempts to protect the sanctity and supremacy of nature at all costs by lashing out against humanity, which brings her into conflict with Batman. While usually portrayed as a supervillain, Ivy has also been an antiheroine at times as well as the primary love interest of Harley Quinn as of The New 52 and DC Rebirth relaunches. A one-piece costume adorned with leaves and vines serves as Poison Ivy's visual motif.
