Charlie is described in the script of "Turnabout" as a black man in his late twenties and moving "like a street-tiger. His heritage is black-Italian: when black guys weren't beating on him for being Italian, the Italians stomped him for being in the wrong neighborhood. Fed up, Charlie took a stint as a Navy SEAL, and forged his street-moves into martial arts mastery. He's realized his dream of owning this dojo by hard work and sweat. He's friendly but tough as hell." The dojo is described in the script of "Turnabout" as "spare but clean: a testosterone-shop in the old style."
