 The Voord were conceived as the villains for the season 1 "Doctor Who" serial "The Keys of Marinus" by writer Terry Nation, who previously conceived of the Daleks for an earlier season 1 Doctor Who story.As with the Daleks, Nation's script left the description of the Voord vague, and the design was developed by costume designer Daphne Dare.Freelance contractors Dave and John Lovell created the three heads and three pairs of black gloves that were used as part of the Voord costumes for less than 70 pounds.
