Zec was a human space pilot. He had brown hair.
While serving as Space Pilot Commander Don Morais' co-pilot during a space reconnaissance mission, he fought battled a group of Daleks, narrowly escaped the Vale of Holocaust, and discovered the long-lost Spaceship One. This was actually a Dalek trap, and they were brought to Skaro, where they were forced, under threat of exposure to plasmoral constrictive gas, to find doranium for them. 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.
