Vic Fontaine

Vic Fontaine is a highly advanced self-aware holographic character. He works in the lounge of a Las Vegas hotel as a singer in a holoprogram which it kept on permanently in one of the holosuites in Quark's on Deep Space Nine.

Vic has abilities beyond that of normal holodeck characters, he is aware he is a hologram and has access to station files allowing him to keep up to date with 'real world' current affairs. Vic also has the ability to freely roam other holoprograms - he once requested Taran'atar 'keep it down' in one of his training programs.

Vic acts to an extent as an unofficial councillor on DS9 and enjoys familiar relationships with many of the stations residents.
