Father of Mine

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