Zombie

Zombies, also spelled zombi (PROSE: White Darkness), were "the living dead," creatures of the undead in different cultures.

Illusions

While not truly being "undead," it was possible (and often done by tribes in Haiti) to trick a human into believing they were one of the "living dead" using the drug tetrodotoxin. In correct doses, it could lower the consciousness of a person and take away their sensory nerves. The person would then be buried and dug up, making them think they had been brought back to life. They would subsequently be used as slaves. (PROSE: White Darkness)

When discussing the idea of a "planet ruled by zombies", the Fourth Doctor remembered the quote that "the living are just the dead on vacation." He told Romana II that one could always identify a genuine zombie by the fact that their skin was cold to the touch, which aided him in his discovery that the Movellans were robots.

Rose Tyler called the Gelth, while possessing dead human bodies, zombies. (TV: The Unquiet Dead) To Sarah Jane Smith, she described people infected with the Empty Child virus as "gas mask zombies". (TV: School Reunion)

In 2008 Sarah Jane Smith watched the people who had drunken Bubble Shock! and were calling "Drink it". Sarah Jane thought they were spreading out like an army of zombies. (PROSE: Invasion of the Bane)

Behind the scenes

• David A. McIntee, when writing White Darkness, took inspiration and facts from the non-fiction book The Serpent and the Rainbow, which detailed accounts of zombification that occurred in Haiti in the early 20th century. He advised staying away from the film version.
• The humanoid antibodies created by the Exxilon City's "brain" to destroy the Third Doctor and Bellal in part four of Death to the Daleks were credited as "Zombies" in Radio Times.
