Mutant Dalek embryo

Mutant Dalek embryos were failed attempts at creating new Daleks on 1930 Earth. They looked vaguely like Kaled mutants, but the lacked the eye and tentacles of their Last Great Time War mutations. The Cult of Skaro attempted to breed new Dalek mutants utilising their own genetic material, however it was not strong enough to survive the process. The resulting lifeless genetic matter was discarded in the nearby sewers, where the Tenth Doctor found one, alerting him to the Daleks' presence in Manhattan. The Cult moved on to converting humans into human-Daleks in the Final Experiment. (TV: Daleks in Manhattan)
