Mother Nothing
From Tardis Wiki, the free Doctor Who reference
Mother Nothing was a giant beetle cannibal who emerged as the last of her kind when her home planet was struck by a great famine, leading her to consume her own hatchlings as well as her entire race. She died as a result of a confrontation with Captain Jack Harkness in a failed attempt to acquire the diamond engine of a space station. (AUDIO: One Enchanted Evening)
