In the Sixth Doctor story "Revelation of the Daleks", it is revealed that Davros managed to escape at the end of "Resurrection" and has gone into hiding as "The Great Healer" of the funeral and cryogenic preservation centre Tranquil Repose on the planet Necros. There, creating a clone of his head to serve as a decoy while modifying his body so that it can fire electric bolts and his chair is able to hover, Davros uses the frozen bodies to engineer a new variety of white armoured Daleks loyal to him, but he is captured by the original Daleks and taken to Skaro to face trial.
