A possible Mirror Universe version of Vic Fontaine appears in "The Emperor's New Cloak". This version of Fontaine appears to be human (no explanation for this is given), and is shot dead during a phaser battle. Fontaine is forced out of his club in "Badda-Bing Badda-Bang" by the American Mafia, who turn it into a casino. The rest of the crew want Fontaine's bar back the way it was, and are faced with either resetting the program and losing the hologram's memory of the crew or playing along with the story and returning the bar to Vic. So Captain Benjamin Sisko (Avery Brooks) leads a team to steal the casino's takings. Upon their success, the program restores the bar to the way it was, and Fontaine celebrates by singing "The Best Is Yet to Come" to the crew. During the finale of "Deep Space Nine", "What You Leave Behind", Quark passes the time during the attack on Cardassia Prime by playing Go Fish with Fontaine. Later, after the victory and the defeat of the Dominion, the crew return to Vic's bar for a celebratory party.
