The original and most widely known Catwoman, Selina Kyle, first appears in Batman #1 (Spring 1940) in which she is known as The Cat. As an adversary of Batman, she was a whip-carrying burglar with a taste for high-stake thefts.
Since the 1990s, Catwoman has been featured in an eponymous series that cast her as an anti-heroine rather than a supervillainess. The character has been one of Batman's most enduring love interests, and has occasionally been depicted as his one true love.
Poison Ivy is depicted as one of the world's most prominent eco-terrorists. She is obsessed with plants, botany, and environmentalism. She uses toxins from plants and her own bloodstream for her criminal activities, which are usually aimed at protecting the natural environment. She creates love potions that ensnare Batman, Superman, and other strong-willed individuals. Fellow villain Harley Quinn is her recurring partner-in-crime and possibly her only human friend.
Harley Quinn, (as Harleen Quinzel) was once a highly respected Arkham Asylum psychiatrist who fell in love with the Joker and became his accomplice and on-again, off-again girlfriend. Harley's relationship with the Joker is one of the most popular in the DC Universe. While he often abuses her, sometimes to the point of desiring to kill her, there are as many instances that show a mutually affectionate side to their bizarre relationship. Certain stories imply that the Joker wrestles with the confusing reality of actually caring for someone, giving in to the sentiment more or less, at times, depending on his mood or state of mind.
As one of the Gotham Girls, Harley has become very close friends with Poison Ivy, sharing an apartment with her when she has the sensibility to stay away from the Joker. (It has been suggested that Harley and Ivy share a bed as well, finding supportive comfort in each others' company.)

Barbara "Babs" Gordon, a quiet librarian, and the daughter of Batman's supporting character Police commissioner James Gordon, debuted in Detective Comics #359 (cover-dated January 1967, but released in November 1966). In her debut appearance, Gordon is on her way to a masquerade ball dressed as a female version of Batman when she disrupts a kidnapping attempt on Bruce Wayne by the villainous Killer Moth. This attracts the attention of Batman and leads to her establishing a crime-fighting career as Batgirl.
