Lucifer (voice of Jonathan Harris) was assigned diplomatic duty with Count Baltar (John Colicos), a traitorous human who helped silver robot warriors track down escaping survivors of a premeditated Cylon holocaust.

Lucifer provided updates on the humans whereabouts and acted as a liaison between the Count and the Cylon's Imperious Leader.

In appearance, Lucifer had a transparent tear dropped-shaped head filled twinkling lights and draped a black cape with high collar about its body. Beneath the costume was 4-foot 11-inch actor Bobby Porter. See also "Cylon Centurions"
