The Skishtari were known as one of the most fiendish races in the universe.
Skishtari resembled giant golden cobras with scarlet eyes. (AUDIO: Survivors in Space) The Skishtari laid eggs in the populace of inhabited worlds. Skishtari eggs took thirteen years to hatch. (AUDIO: Tsar Wars) A Skishtari gene egg had a psychic link with its host. (AUDIO: Aladdin Time)
Travelling through wormholes was second nature to the Skishtari. (AUDIO: Tsar Wars) They regarded themselves as masters of genetic and spatial-dimensional engineering. (AUDIO: Survivors in Space)
In 2011, the Fourth Doctor said that the Skishtari had ransacked planets in the galaxy for many decades. (AUDIO: Tsar Wars)
