and a single, oblong appendage box running across the front of the body. A Dalek Emperor prop was also created, being a scaled-down but otherwise faithful reproduction of the version that appeared in The Evil of the Daleks with the addition of large wing-like structures to the sides. The Dalek props used in the production were built by the theatrical suppliers Suffolk Scenery. Dalek variants in comics, books, audio dramas and video games Various writers and artists have created new Dalek variants for media other than television, film and the theatre. The depiction of Daleks with coloured casings has also been used to indicate rank, although these differentiations do not constitute separate variants as such. Of particular note in this respect is John Peel's BBC Books Doctor Who novel War of the Daleks in which grey, blue, red, black and gold Daleks are described as having successively higher status, all serving under the Dalek Prime. Other examples are the TV21 Dalek comic strip in which a Black Dalek is shown acting as second-in-command to the Golden Emperor, and Trevor Baxendale's novel Prisoner of the Daleks where a Dalek Inquisitor General is described as being of the "New Series" design but having a casing of gunmetal black with gold slats and hemispheres. Golden Emperor Dalek The concept of an Emperor Dalek was first introduced in The Dalek Book (1964), re-appearing shortly thereafter in the TV21 comic strip The Daleks (1965–1967). In the comic strip version of events the planet Skaro was inhabited by two warring humanoid species; the tall, peaceful Thals and the aggressive blue-skinned Daleks. The Daleks build a neutron bomb to finally destroy the Thals and bring the conflict to an end. A meteorite storm causes the device to detonate prematurely, devastating Skaro and the planet's civilisations. The only survivors of the Dalek race are the scientist Yarvelling and the warlord Zolfian. While exploring the shattered remains of their world they are attacked, and then interrogated, by a prototype war machine which Yarvelling had created shortly before the holocaust. It is implied that these machines were intended to act as semi-autonomous robotic warriors. It informs them that it is actually a mutated Dalek, the result of radiation from the neutron bomb explosion, which has commandeered the casing to use as a travel machine. It says that there are many more mutants and persuades Yarvelling and Zolfian to build more
