Michael is the son of infamous mafia boss Fat Tony, but he does not wish to follow in his father's footsteps and go into the family business of "waste management." He has a passion for cooking and is a great chef.
His mother died when he was younger and he has no siblings. Fat Tony was once put in a hospital by rival gangs and Michael was offered to take over the mafia for a while.
He didn't want to, and Homer and Bart took over the mob instead, although later he apparently willingly poisoned the mafia that had attacked his father.
- Michael is an obvious homage, in name, appearance and behavior, to Michael Corleone from The Godfather Trilogy.
- His name may also be a reference to actor James Gandolfini, who played Tony Soprano in The Sopranos, and his own son, Michael Gandolfini.
- Marge Simpson sometimes drives him home from school.
