In the Fifth Doctor story "Resurrection of the Daleks", Davros (Terry Molloy) is released from his space station prison by small Dalek force aided by human mercenaries and Dalek duplicates. The Daleks require Davros to find an antidote for a Movellan-created virus that has all but wiped them out. Believing his creations to be treacherous, Davros begins using mind control on Daleks and humans, ultimately releasing the virus to kill off the Daleks before they can exterminate him. Davros expresses a desire to build a new and improved race of Daleks, but he apparently succumbs to the virus himself, his physiology being close enough to that of the Daleks for the virus to affect him.
