Sofia Falcone (The Penguin)

Sofia Gigante (née Falcone), also known as the Hangman, is the daughter of the late Carmine Falcone, and is a crime lord and mass murderer. Following her father's death at the hands of the Riddler and her brother's at the hands of the Penguin, she returns to Gotham City after a stint at Arkham State Hospital to gain power over the Falcone Crime Family as its new boss. After being betrayed by Penguin a second time, she massacred most of her immediate family members and reformed her father's empire into the Gigante Crime Family, with her as the boss. After Penguin destroyed the Gigante Crime Family and kidnapped Sofia, instead of killing her, Penguin orchestrated a much worse fate for her; Sofia's worst nightmare came true, and she was sent back to Arkham indefinitely for her key role in the Bombing of Crown Point mass murder. In Arkham, she received a letter from Selina Kyle, her half-sister, giving her hope for the future.
