Suit Creature
From Tardis Wiki, the free Doctor Who reference
The Suit Creature was a living skeleton in a space suit, which had been taken over by the Vashta Nerada. It used to be Proper Dave, but Other Dave and Anita later became suit creatures as well. (DW: Silence in the Library/ Forest of the Dead). It kept on repeating the last thing the human that got taken over said (DW: "Forest of the Dead")
