Marion Anthony "Fat Tony" D'Amico, also known as William Williams, was the Springfield mob boss. He has been behind several of Springfield's criminal enterprises. His rackets included illegal gambling, cigarette smuggling, bootlegging, fraud and selling false IDs. He had also been seen bribing and making secret deals with Mayor Quimby.
Fat Tony has a son, Michael, whom he used to drive to or from school. He was a widower and said his wife, "was whacked, by natural causes." Fat Tony and his associates conducted business and socialized in the Legitimate Businessman's Social Club.
Fat Tony was born Marion Anthony D'Amico, in Brooklyn, New York. He was very poor. When his parents were evicted, he ran away seeing they couldn't offer him any more. He would usually sleep at a friend's house, a supermarket (he would sneak in when it was closed), vacant buildings, or on the streets. He also implied that he dreamed to work as either a pizza man, organ grinder, or leaning-tower maker, but his dreams ended up ruined at some point. Finally, a young man in the mafia found him sleeping on a bench in Central Park and got him a job in the mafia. This man was named Salvatore Tessio; he had taught Tony everything. One night when Tony was 20 years old, Sal was found killed. Tony learned to fend for himself after that and, using what Sal taught him, he worked his way up from a henchmen to a capo. Eventually, he married Anna Maria D'Amico and had a son named Michael D'Amico. Unfortunately, an enemy tried to shoot Tony, and Anne Maria protected him by jumping in front and later dying, although Fat Tony would later claim she was "whacked of natural causes".
Fat Tony is a widower. He had a wife named Anna Maria with her grave in Springfield Cemetery who was "whacked by natural causes." Tony has a son named Michael, whom he planned to have follow in his footsteps as the leader of the Springfield mob.  Following his death, it was revealed that he had a cousin called Fit Tony, who took Fat Tony's place running the Springfield mob.
DeathIn Donnie Fatso, Fat Tony collapsed and died in Homer's arms. His death was most likely caused by a heart attack or cardiac arrest. He was replaced by his cousin Fit Tony.
Behind the Laughter
Originally, Tony was going to be voiced by Hank Azaria. However, since Fat Tony wasn't a very good drawing, Groening decided to make a "Special Guest Voice" do him. Sheldon Leonard was originally supposed to be the voice of Fat Tony, but they weren't able to get him, so they chose Joe Mantegna instead. In one DVD commentary, it is stated that Mr. Mantegna is so enamored with the character that he has forbidden to allow anyone else to voice Fat Tony; he even voiced him when the script only called for a couple of grunts ("Sex, Pies, and Idiot Scrapes"). However, this didn't keep Phil Hartman from filling in for him on one occasion ("A Fish Called Selma").
Fat Tony is a pastiche of mobsters from movies and dramas, especially The Godfather franchise (and in later seasons The Sopranos). His nickname may be a reference to "Black Tony", the Don of the fictional Stracci family in The Godfather.
"Moe Baby Blues" featured several interesting references relating to Fat Tony. To entertain his subordinates, Fat Tony puts an orange slice in his mouth in imitation of Don Corleone from The Godfather. Minutes later, Fat Tony responds to an emotional scene by saying "I haven't cried this much since I paid to see Godfather III" (in which Mantegna played the character Joey Zasa, one of the inspirations for Fat Tony).
His son's name is a reference to Michael Corleone.
On several occasions, Fat Tony has said something that begins as ominous mafia language, only to be proven innocent; one example is "We are going for a ride... By which I mean the carpool" and "Now who's ready to sleep with DA fishes?... Because I brought this Finding Nemo comforter!" This also led to some confusion among his fellow mafia members, such as the time when Troy McClure was involved in a scandal involving a sexual attraction to fishes, and he told his fellow gang members that he was "sleeping with the fishes", causing them to misinterpret the meaning to Troy having died when he was actually meaning that McClure was literally sleeping with the fishes.
Similarly, when disposing of bodies, he and the other members of the mob often uses euphemisms for the cadaver that sound innoculous sounding when dealing with law enforcement. This was showcased twice, where he, or rather, Louie, disposed of a cadaver rolled up in a rug inside a goodwill donation bin to dispose of the body, with Chief Wiggum inquring what they're donating, claiming it was a "beanie baby". Similarly, when the town of Springfield was trying to clean Lake Springfield, Fat Tony, before leaving when talked out of dumping at the lake, mentioned that he will have to take his "yard trimmings" elsewhere, although Lou (and allegedly Wiggum) suspected it was in fact a cadaver he was going to dispose of.
His house also strongly resembles that of Tony Montana in the movie Scarface.
Fat Tony also bears similarities to notorious mobster Al Capone.
- Fat Tony being a competent violinist may be a reference to the Thompson Submachine gun (Tommy), which was the mafia's weapon of choice. It was nicknamed the Chicago Typewriter, and was generally carried in a violin case. The same episode that revealed this also used this reference by having Krusty and Homer taking several violin cases containing Tommies with them when searching for the former's daughter's violin, also unintentionally instigating a shootout during a mob summit.
- Fat Tony's name probably comes from a Simpsons re-recording animator, also named Anthony D'Amico.
- When Fat Tony came round to kill Homer, after Homer's community police force start-up busted him, Marge complained about Fat Tony's choice of a vocation, when he could be a pizza man, organ grinder, or a leaning tower maker. Fat Tony replied saying, "You are listing my broken dreams."
- After his death, his cousin Fit Tony takes over the Springfield Mafia and Homer teaches him a lesson into becoming the new Fat Tony. Meaning that all of Fat Tony's appearances after this episode are as Fit Tony.
- He is the featured character on the Season 18 DVD/Blu-ray box set.
