Vrock is a vulture-like demon from the Dungeons & Dragons fantasy role-playing game. The name of the heavy metal station in GTA Vice City, V-Rock, is rumored to have been derived from the name of the demon. The official logo of V-Rock includes a vulture as its mascot. It is likely that Vrock was referenced by Rockstar because of the immense popularity of Dungeons & Dragons during the 1980's. Also during the 1980's, a moral panic swept the nation as both Dungeons & Dragons and heavy metal music were considered gateways to satanic behavior. The reference was first found by glenster on Neoseeker. Vrock, however, doesn't physically exist in the game as birds the size of Vrock are nonexistent in Vice City, leaving the myth as unlikely but with a handful of references.
In GTA San Andreas, there is a casino in Las Venturas named the V-Rock. The hotel is a parody on the Hard Rock hotel and casino in Las Vegas.
