Carmine "The Roman" Falcone is the head of the Falcone crime family, and one of Gotham City's greatest crime lords.
While he held a great deal of power in Gotham, this was diminished after Batman emerged and chipped away at his operations. To make matters worse, supervillains such as the Joker soon arrived in the city, and took over much of the criminal underworld.
Ultimately, the straw that broke the camel's back was Hugo Strange's specially trained TYGER force, who almost completely destroyed crime in the city. Faced with imprisonment in Arkham City, he and his family fled to Blüdhaven.
