Preacher (A Town Called Mercy)
From Tardis Wiki, the free Doctor Who reference
The Preacher was one of the population of Mercy. 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. (DW: A Town Called Mercy)
