Embryo

The embryo was an early stage of the Dalek mutants created by Davros. (TV: Genesis of the Daleks) During the era in which the Daleks were confined to the Dalek City, new embryos were grown in a subterranean level. (AUDIO: Return to Skaro) After the Thal-Dalek battle had knocked out the city's main power, (TV: The Daleks) autonomic protocols sealed off the incubation level and placed the embryos in suspended animation until power was restored to the city. Spending decades in such a state allowed the new generation of Daleks to overcome their dependance on radiation. (AUDIO: Return to Skaro)
