A serial killer who murders police officers on every holiday of the year, leaving behind a version of the children's word game "Hangman" (with key letters missing) with each new victim. All of the victims are police officers who, in one way or another, helped Harvey Dent rise to his position of District Attorney. In the end, the Hangman is revealed to be Sofia Falcone Gigante, daughter of the late crime boss, Carmine Falcone.

After seeing her father murdered by Two-Face, Sofia charges forward and is restrained by Catwoman. During the struggle, Catwoman scars the right side of Sofia's face and the two tumble out a window. Catwoman tells Batman that when Sofia fell, her bolo/whip became tangled around Sofia's neck. The whip then caught on a stone gargoyle and threw Sofia through another window, and the broken glass sheared off the right side of her face. Catwoman follows Sofia to Europe where she undergoes plastic surgery to restore the damage done to her face.

Sofia, is shown with the left side of her face scarred, which we find she did herself after the surgery to be closer to her father's spirit (who was himself scarred by Catwoman). Catwoman tells Batman she was able to find the doctor who treated her ruined face, but not one who treated her paralysis. Her paralysis was a ruse, however, to appear weak and avoid being a suspect in the Hangman murders. All of the victims of the Hangman murders are police officers who, in one way or another, helped Harvey Dent rise to his position of District Attorney. Her final target is Two-Face himself, although Batman saves him and Dent kills Sofia with a gunshot to the head. Batman receives some additional help from Dick Grayson, a young orphan he adopts as his ward and trains as his sidekick, Robin.
