Cerberus is the host of a club named Mysteries in the virtual world of New Cap City (CAP: "Ghosts in the Machine"). Cerberus routinely selects a member of his audience and poses a riddle to them. Winners are given more insights into the New Cap City game, while losers are "killed" and thus ejected from the game. People who refuse to play along are thrown out of the club.
- In Greek and Roman mythology, Cerberus is a three-headed hound who is the guardian of Hades.
