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 a wandering cyborg who wanted to terminate Kahler-Jex for his crimes as a war criminal. When the Gunslinger entered the town, he was inside the church praying for the population's survival. (DW: A Town Called Mercy
