Zombie

"When there is no more room in Hell... the dead shall walk the Earth."

- Infamous quote used in The Dead series

Modern Zombies are rotting corpses, still mobile, usually unintelligent and feral beasts seeking to consume the flesh of the living, for reasons that vary depending on the source material. These modern zombies were originally created by George A. Romero for his The Night of the Living Dead movie, which was by extension a reimagining of I Am Legend, which tells about ghoulish vampires that, despite being similar in movements to zombies are still intelligent.

Most major movies that feature zombies has a single, named zombie who serves as the film's "mascot" zombie. This has been the case ever since the original The Night of the Living Dead.

They have become extremely popular in media, to the point of severe oversaturation. Actual plans to survive a potential zombie holocaust have been placed into effect both by actual government/military organizations and by individuals.

Trivia

 * In nearly all films and media involving zombies, they are never overtly referenced as "zombies", instead being called "they" or "them" most often. This is occasionally poked fun at.
