Father of Mine

Father/Husband of Mine was the patriarch of a criminal family known 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. Despite being the head of the family, he allowed Son of Mine to take charge. He was the second of the family to take a host. After the Family was defeated in the Battle of Farringham School, the Doctor wrapped Father of Mine in supposedly unbreakable chains made of dwarf star alloy and left him in an underground chamber. (TV: Human Nature / The Family of Blood). However, these were later broken by Daughter of Mine upon her escape from her imprisonment in a mirror. He was ultimately trapped by the Doctor in the Event Horizon of a collpasing galaxy along with Mother of Mine after the unsucessful escape attempt (Prose: Blood Will Out)

Personality
Despite being the patriarch of the Family of Blood, Father of Mine often let Son of Mine take charge. However, he was just as psychotic, ruthless and murderous as the rest of his family and never hesitated to kill people on a whim. He had a tendency to yell, scream and shout violently, even when no one else was present. (TV: The Family of Blood)
