Father of Mine

Father/Husband of Mine was the patriarch of a criminal family known only as the Family of Blood. He possessed the body of Farmer Clark in 1913 to find the Tenth Doctor and steal his near-immortal life essence. After the Family was defeated, the Doctor wrapped Father of Mine in unbreakable chains made of dwarf star alloy, and left him suspended in the event horizon of a black hole to make him see how horrible it was to live for all eternity.
