Sofia Falcone is a DC Comics villain associated with the character Batman. Debuting in the 1996-97 comic book limited series Batman: The Long Halloween by Jeph Loeb & Tim Sale, she is introduced as a member of the Falcone crime family, who assists her father Carmine Falcone in unearthing the identity of the "Holiday Killer"--later revealed to be Sofia's own brother Alberto Falcone, a mass-murderer who had been indiscriminately killing Gotham City's citizens in correlation with holidays in the yearly calendar.
