Preacher (A Town Called Mercy)
From Tardis Wiki, the free Doctor Who reference
The Preacher was a Christian cleric in Mercy, Nevada at least during the period following the American Civil War. In 1870, he prayed for the freedom of their town after it was trapped by the cyborg Kahler-Tek who wanted to terminate Kahler-Jex for his crimes as a war criminal. When Kahler-Tek entered the town, the Preacher was inside the church praying for the population's survival. He protected a small girl who had accidentally toppled a few books, attracting the attention of the cyborg. (DW: A Town Called Mercy)
