Sal Maroni
Sal Maroni appears in The Dark Knight as the head of the mob (now that Carmine Falcone is in Arkham Asylum). He forms a brief alliance with Gambol to fight Batman and Harvey Dent. In a meeting with Gotham’s mobsters, Sal were confronted by the Joker who himself offers to kill Batman for half of all their money, but the mob refuses; they change their decision after Batman captures Lau in Hong Kong and delivers him to the Gotham police. Lau’s testimony allows Dent to put all the mobsters in Gotham on trial, but as one of the bosses Maroni is able to make bail. Maroni is next seen when he is being interrogated by Batman above a club hours after the apparent murder of Lieutenant James Gordon. Despite Batman breaking one of his legs by throwing him off a building, Maroni doesn’t disclose the Joker’s whereabouts, instead lecturing Batman about letting people die by not turning himself in to the Joker. Later in the film after countless people and several city officials have been killed and Dent badly scarred because of the Joker, Maroni realizes that joining forces with the Joker has created more chaos than he can handle and he tells Gordon the Joker’s location.
He is interrogated by a scarred Harvey “Two-Face” later in the film, and Two-Face shoots the driver of his limo, causing it to flip over. Maroni’s status after this is unknown.
