Salvatore Maroni

Don Salvatore Maroni, or Sal for short, was the second biggest don in Gotham City and head of the Maroni crime family. He was the rival of Carmine Falcone and was part of a mob war orchestrated by Oswald Cobblepot. He was the tertiary antagonist of the first season of Gotham (as Oswald was the primary and Fish Mooney the secondary).
