Cyberman (The Year Ahead)
From Tardis Wiki, the free Doctor Who reference
In November 1992, to celebrate the programme's 29th anniversary, a Cyberman worked with a Dalek, Ice Warrior, Sea Devil and Sil to extract the Earth's magnetic core. The Cyberman did not know what to do with it once they were successful, however, and nor did any of its comrades. (NOTVALID: The Year Ahead)
