Big Boy, a fictional analog for Al Capone, made his first published (though apparently not chronological) appearance in Dick Tracy's second Sunday strip (October 11, 1931).

By this time, Big Boy's power had faded considerably from an autocratic boss to merely one of the members of the executive council of the nationwide criminal cartel referred to, in the strip, as the Apparatus.

As Tracy and his partners, Sam Catchem and Lizz, take precautions and investigate, a professional criminal bomber, "Little" Littel, makes his own attempt with a car bomb.

As evidence piles up that the attempts on his life are Mob-related, Tracy publicly announces that he is taking command of the Organized Crime Unit in order to retaliate.

This prompts the Apparatus board to confront Big Boy and tell him that they will not tolerate something so brazen with such serious consequences as attempting to murder police officers.

With the promise of a foreign home to escape the Apparatus' reprisal, and an extra 1 million dollars on top of the original bounty, the Iceman makes his attempt and eventually fails.

In a short, two-week sequence written by the strip's former police technical advisor, Jim Doherty, and run between 28 April 2019 and 5 May 2019, Big Boy is referred to as "Gabe Famoni," and it is asserted that, not only was he assisted by a brother, "Sal Famoni" (apparently a fictional analogue for Frank Capone), but that "Cut" and "Muscle" Famon, the villains from a 1935 sequence in which Tracy was hired as a reform police chief for the gangster-ridden suburb of "Homeville," were both half-brothers of Big Boy's.

In the film, Big Boy Caprice is the former protégé of crime lord Lips Manlis (Paul Sorvino), whom he eventually murders after rising to power.
