Father of Mine

Father/Husband of Mine was one of the Family of Blood. He possessed Farmer Clark in 1913 in order to find the Tenth Doctor. After the Doctor blew up their ship, he tied Father of Mine in unbreakable chains made of dwarf star alloy and left him suspended at a black hole event horizon to see how horrible it was to live for all eternity.
