|Real name:||Salvatore Maroni|
|Portrayed by:||David Zayas|
Maroni befriends a restaurant worker named Paolo who works at his restaurant, who is really Oswald Cobblepot under a new alias.
Maroni makes a power play for the new development at the Arkham Asylum site, and even contracts Richard Gladwell to take out the Mayor, Aubrey James. Maroni catches Cobblepot snooping on the job and tells him to mind his own business. Maroni's restaurant is raided by masked attackers, who try to rob it. Cobblepot saves most of the money, and Maroni promotes him to manager - unaware that Cobblepot himself had instigated the robbery. The upshot is that, in an attempt to appease both sides in the power struggle, Mayor James puts forward a hybrid plan, giving Don Falcone a low-income housing area to build, but granting Maroni the rights he wanted to waste disposal.
Sal Maroni makes plans to rob a casino owned by Carmine Falcone. Carmine Falcone meets with the mob leaders on his side to detail about what to do with Sal Maroni. Sal Maroni later watches the news of the "Viper" drug when he thinks that they might be of good use. Oswald tells Sal Maroni that he knows the janitor there that might be of help to them. Sal Maroni claims that "Penguin" is a good name for him. Oswald later tells Sal Maroni that his real name and how he used to work for Fish Mooney until Carmine Falcone's men tried to kill him. Sal Maroni then pins Oswald's head to the table. Sal Maroni later sends his right-hand man to pick up James Gordon at the police station where Sal Maroni wants to see him about Oswald Cobblepot. James Gordon is brought to Sal Maroni at his restaurant where he wants to get confirmation about Oswald's story about Carmine Falcone to determine who is telling the truth. Sal Maroni hears from Jim Gordon about his investigation on Thomas and Martha Wayne and how he covered up Oswald's death to fool Carmine Falcone, Fish Mooney, and the Gotham City Police Department. Sal Maroni sees that Oswald is right and spares his life while letting James Gordon go. Sal Maroni states to James Gordon to keep their meeting private and that he might call on him again. After James Gordon leaves, Sal Maroni plans to use Oswald Cobblepot in their fight against Carmine Falcone. Later that night, Oswald and Sal await their men to come back from their heist at the casino. Upon the heist being complete, Sal has Frankie drive off.
