Harley Quinn.

The original Harley Quinn costume consisted of a tight-fitting red and black bodysuit with white collar and cuffs. A jester's hat completed the look, emphasizing her clownish nature. She's a blonde, but you can't tell under the clown hat.

The makeup was fitting for a villainess: luscious ombre lips, black around the edges and red inside, and a theatrical mask that covered her eyes.

The story of Harley Quinn (Harleen Quinzel). As a teenager, Harley was a talented gymnast, and her victories in competitions secured her a place at university, but her real goal was a prestigious graduate degree in psychology, and she got it by seducing her teachers, Harley was going to become a famous psychologist. One of the regular patients at the clinic was the Joker: Harley had therapeutic talks with him and gradually began to fall in love with the villain. The Joker constantly lied to Harley during therapy and made her believe that he was a tragic person, which is why Harley began to fall in love. Harley had a breakdown when Batman severely beat the villain who was trying to escape from the hospital, Harley was convinced that the Joker was just a wounded soul who wanted to do good and fun, which, of course, is not true. Quinn robbed a costume store, dressed in her classic red and black outfit and helped the Joker leave Arkham. When the hospital management found out about this, Harley herself ended up in the clinic, but as a patient. After the events of "No Man's Land", when an earthquake destroyed Gotham, Harley was able to escape from the destroyed Arkham, find the Harlequin costume and find the Joker, who allowed his savior to join the gang.

Harley Quinn hates Batman with every fiber of her being. She believes that Batman is the reason the Joker doesn't love her, because the Joker is constantly preoccupied with him. Once, the Joker beat Harley Quinn for saying, "Why do you need these plans? Batman can and should just be shot." Harley Quinn believes that the Joker loves Batman more than her, and therefore hates Batman VERY, VERY much.

Harley Quinn wants to become a mother and have a child with the Joker.

Harley usually follows the Joker's instructions without question, but sometimes she argues with him. For example, when the Joker called Harley "nurse," she got angry and asked him to call her doctor. Harley insisted, and now the Joker calls her doctor instead of nurse if their roles in a crime are doctor/doctor or patient/doctor.
