Taran android
From Tardis Wiki, the free Doctor Who reference
Taran androids were intricate androids which looked exactly like the human colonists. They were used by them to replace their dead when they were struck by a plague.
An android of Prince Reynart was used to distract Grendel of Gracht from assassinating him. The android was used in Reynart's place, at his coronation. (TV: The Androids of Tara)
