Flesh time

The flesh time was an expression used by the Urbankans to denote the part of their lives spent in their organic bodies. Aboard Monarch's ship in 1981, nearly all Urbankans had been converted into androids except for the Minister of Enlightenment, Minister of Persuasion, and the Monarch himself. After Tegan Jovanka sketched two bodies for them, the Minsters became androids whose appearance was based on the sketch. Only Monarch was still in flesh time when the Fifth Doctor hurled Urbankan poison at him and he was shrunk. (TV: Four to Doomsday)
