Zombie

Zombies were, according to the Fourth Doctor, "the living dead". He went on to tell Romana II that one could always identify a genuine zombie by the fact that their skin was cold to the touch. (DW: Destiny of the Daleks) Rose Tyler called both the Gelth, while possessing dead human bodies, (DW: The Unquiet Dead) and people infected with the Empty Child virus, zombies. (DW: School Reunion)
