Fat Tony I
Marion Anthony "Fat Tony" D'Amico is the local Mafia underboss and leader of The Springfield Mafia. He is the head of the D' Amico Family which involves his deceased cousin Fat Tony, his deceased sister-in-law Anne Maria D' Amico and his eight year old nephew Michael D' Amico.
Fat Tony II
Fat Tony, originally known as Fit Tony, then Fit-Fat Tony, became the underboss after the original Fat Tony died.
Legs and Louie
Legs and Louie are the two Springfield Mafia hitmen and fellow caporegimes who accompany Fat Tony at all times.
Johnny Tightlips is a caporegime under Fat Tony. He says very little, which spares him from accusations of being a "squealer," but his reticence tends to be unhelpful to himself or others.
When there was a shoot-out in Fat Tony's mansion and Tightlips was shot by accident. When asked where he's injured, he says " I ain't sayin' nuthin'!", and when asked what to tell the doctor he says, "Tell 'im to go suck a lemon."
Frankie the Squealer
Frankie the Squealer, is another member of the Mafia and associate of Fat Tony. However, he does not appear to be very useful to his colleagues in criminal activity due to his uncontrollable habit of squealing (he claims that "it makes me feel big"). On several occasions, the mob has attempted to kill him for his squealing, though they have repeatedly been unsuccessful.
- The D'Amico Family once hired Bart Simpson as a bartender/errand boy in the local mob hangout, "The Legitimate Businessmen's Social Club". The hangout is a gambling place.
- When Homer becomes a licensed Krusty the Klown imitator the D'Amico Family mistake him for the real one and try to collect an assumably massive gambling debt (later revealed to be $49). Krusty loses his daughter's violin to Tony in a poker game, and later sneaks into the mafioso's compound (with Homer's help) to steal it back.
- The family's schemes appear numerous, ranging from supplying rat's milk to the school cafeteria to dabbling in an illegal fireworks racket.
- The gang also attempts to monopolize various legitimate business, once waging war with the local Yakuza over the pretzel business. They are also responsible for maintaining Krusty Burger by keeping McDonald's and Burger King out of Springfield.
- The mafia is also responsible for tobacco, drug, and alcohol traffic. When Springfield re-enacts Prohibition, naturally Fat Tony and crew pay off the cops to allow them to sneak in alcohol.
- The mafia formerly owned the Springfield Isotopes until they sold them to Duff. According to Moe Szyslak it was the last of the D'Amico family owned teams.
Their headquarters are located at the Legitimate Businessman's Social Club.
