Marion Anthony Paul D'Amico, originally known as Fit Tony, later Fit-Fat Tony, and now known as the new and improved Fat Tony is Fat Tony's cousin. He is originally from San Diego but later moves to Springfield to take control of the Springfield Mafia after his cousin's death. Physically speaking, he is identical to Fat Tony with the only difference being that he is initially in much better physical shape.
When Fat Tony dies of a heart attack, Fit Tony moves to Springfield and takes his cousin's place running the Springfield Mob. The pressure of the position gets to him and he begins to over-eat which causes him to put on weight. As a result of this weight gain, he becomes known as Fit-Fat Tony and then simply Fat Tony, as he turned exactly in the same emotional and physical form of his late cousin.
Fit-Fat Tony, now nicknamed Fat Tony, now looks exactly like his cousin to such an extent that it is as if the original Fat Tony never died. This physical resemblance suggests that all previous appearances of Fat Tony are in fact of Fit Fat Tony in a similar situation to Snowball II and Snowball V or Armin Tamzarian and real Seymour Skinner.
In "Penny-Wiseguys", Fit-Fat Tony gets jury duty -- so he names his accountant, Dan Gillick, temporary don. Gillick proposes to Tony to save money by getting rid of redundant mobsters -- but he's mortified when Tony tells him to rub them out. He finds he likes it way too much and asks Homer Simpson to stop him from killing mob members.
In "Bull-E", Fit-Fat Tony is in the anger-management class.
