Biography
On Skaro, the Black Dalek and the Red Dalek collected two humans whose spaceship had been captured, Space Pilot Commander Don Morais and co-pilot Zec. The pair were brought to the Gold Dalek, who gave them the task of acquiring the doranium beneath Skaro's surface, threat of exposure to plasmoral constrictive gas. They discovered a cliff made of the substance in the Valley of Rocks, but rather than let the Daleks have it, Don short-circuited the electric charges in the doranium and together they escaped back to their ship.
