Dexter star David Zayas has signed on for a recurring role in the upcoming Fox series Gotham as ruthless mob boss Sal Maroni. It hasn't been confirmed how many episodes the actor will be appearing in.

In the DC Comics, Salvatore Maroni was one of Batman's first enemies, who took control of the city's unions and drug trade. He is best known as the man responsible for the disfigurement of District Attorney Harvey Dent, and his transformation into the villainous Two-Face. However, the show is set several years before these story lines unfold.

In Gotham, Maroni is second in the criminal underworld behind Carmine Falcone (John Doman), with Season 1 putting Maroni on a "crash course" with his bitter rival Falcone as they battle for control of Gotham's underworld. Sal Maroni was most notably played by Eric Roberts in director Christopher Nolan's 2008 feature The Dark Knight.

Created by Bruno Heller, Gotham follows rookie detective James Gordon (Ben McKenzie) and his partner Harvey Bullock (Donal Logue), as they try to solve the murder of young Bruce Wayne's parents. The show will also provide origin stories for a number of iconic villains, such as Oswald Cobblepot/The Penguin (Robin Taylor), Selina Kyle/Catwoman (Camren Bicondova), Edward Nygma/The Riddler (Cory Michael Smith) and Ivy Pepper/Poison Ivy (Clare Foley ll), along with a brand new villain created for the show, Fish Mooney (Jada Pinkett Smith).

David Zayas, a former New York cop who transitioned into acting in the early 1990s, is best known for his portrayal of Angel Batista on Dexter. He most recently recurred on the FX comedy series Saint George.
