Contestant

From Tardis Wiki, the free Doctor Who reference
Contestant

By 200,100, every human on Earth was a potential contestant for the game shows broadcast aboard the Game Station by the Bad Wolf Corporation. They were transmatted to the space station in Earth's orbit. Contestants who lost the games were seemingly disintegrated; in reality, they were transmatted to the Dalek Fleet for processing into Daleks of human origin. (TV: Bad Wolf)
