Zombie

Brains...

Zombies are a type of undead creature that is popular in science fiction and fantasy.

Characteristics

In popular culture, zombies are animated corpses. Unlike (at least modern) vampires, zombies are generally subject to decay and have little or no intelligence. In the source myths, zombies are raised to serve by Voodoo priests. In modern fiction, zombies are reanimated by things such as radiation, chemical compounds, or micro-organisms; they may even be technically alive, just altered in behavior by whatever created the zombie effect. Magically re-animated zombies still appear in modern fantasy literature, as well, usually as low-end cannon fodder and/or as defensive measures.

Typical movie zombies possess the following attributes to varying degrees:

• Minimal cognitive abilities: At most they are capable of basic tool use, like using a rock to break a window. They do not make plans or organize, they just respond to stimuli.
• Hunger: They usually have a primal urge to kill and eat live animals, but not carrion (meaning they don't attack other zombies). It's not clear why dead zombies hunger, but feeding may slow their rate of decay. Even living zombies won't attack other zombies, although the reason for such behavior is unclear.
• Contagion: People who are bitten by zombies typically die and reanimate as additional zombies (presuming they are not consumed by other zombies). Even if the condition isn't spread solely by zombie bites, the infection from a bite is certain to kill (or "turn") the victim.
• Slowness: Zombies generally don't move very quickly. Unless pursuing prey, they tend to wander aimlessly or become dormant, although some have dim memories of their past lives, which causes them to repeat common behaviors from when they were living. "Fresh" (or living) zombies may be able run as fast as a living human, but decay and accumulated damage tends to slow them down over time.
• Relentlessness: Zombies generally don't feel pain and will press on regardless of damage. In most zombie movies, the most efficient way of destroying them is to shoot them in the head, as the body won't function if the brain is destroyed. Some zombies can only be defeated by enough damage to make them immobile and harmless, such as total dismemberment. Zombies that are technically alive can be killed by any mortal wound, although lesser injuries will not deter them.

Individual zombies can be a danger, but they can usually be dispatched by a person who is knowledgeable and reasonably prepared. Zombies typically only pose a threat in large groups, although their ability to spread disease is always a hazard.

Zombie Apocalypse

A common scenario in fiction is that of a zombie outbreak which threatens or destroys human civilization. However, such scenarios are unrealistic. Modern weapons (particularly armored fighting vehicles, belt-fed automatic weapons, artillery, and airpower) are more than capable of bringing down large numbers of zombies with minimal risk to the humans operating them. Zombies lack the mental ability to counter these tools; they have no foresight and no planning ability, they simply attack prey on sight.

Despite the limitations of zombies, a number of of Zombie Survivalist Fanwhores believe that the military could not contain a large-scale zombie outbreak.
