Duela Dent is a psychopathic young woman who took residence in Gotham's underground sewers as a tribal leader going by the name Joker's Daughter. She now lives to prove the women of her tribe are superior to the men as well as giving a twisted view on beauty standards.
Duela was born to a happy couple somewhere in the suburbs outside of Gotham. Duela's father immediately became uneasy as soon as she was born. As she grew older Duela proved to be a strange child committing odd acts such as trapping a spider in a light bulb, making a mobile for her bed out of knives and creating a corset out of barbed wire. When she turned twelve she took in an "ugly dog" and it was soon thrown out by her father. Duela's parents took her to a hospital after seeing she had been cutting her face with a box cutter. Duela struggled through her surgery to fix her face thus resulting in half of her face being deformed. Though her parents were appalled by her new appearance, Duela seemed to revel in it, stating she was "flawless". That night her parents argued over Duela's place in their house as she listened in. Eventually, Duela ran away from home.
Duela arrives in Gotham City's sewers along with a pet cat as they search for The Nethers, the underground society that resides in the sewers in tribes. Along her journey she finds The Joker's face, mistaking it for her reflection. She dons the flesh and uses it to assert her power over a nearby couple where the man is shown to be treating his "mate" unfairly. Duela angrily confronts the man and the couple mistake her for Joker, quickly surrendering. Duela uses a half moon piece of metal she found to brand the man's face with a smile as she demands to know where the tribal leader is. Many women of the tribe then escort Duela to the tribal leader, Charon, who refers to her as The Joker's Daughter.
