Father of Mine
From Tardis Wiki, the free Doctor Who reference
The Father of Mine was one of the Family of Blood, who possesed farmer Clark in 1913, in order to find The Doctor. When he blew up the Fathers ship, he tied him in unbreakable chains made of Dwarf Styar alloy and left him there to see how horrible it is to live for all eternity. (DW: Human Nature/ Family of Blood)
