Zombie

Zombies (ゾンビ) are a type of undead beings that are reanimated corpses with a hunger for the flesh of the living.

Background
Zombies are always violent and are usually searching for living organs and flesh to eat. Zombies are mute and will-less, reanimated by a supernatural force, usually for some evil purpose. Zombies are attracted to sounds, since it could be food, so they would approach the source of any sound they hear.

There appears to be at least two variants of Zombies. The first one being the natural occurring Zombies that arise from cemeteries and battlefields due to old grudges and hatreds. The second being artificially produced through a curse or magic such as:
 * Squire Zombie
 * Animate Dead
 * Freezing Zombies

Appearance
Zombies have the same body shape as living humans. Pieces of flesh tend to fall off any part of the body because of their rotting bodies.

Abilities
Zombies possesses roughly three times the physical strength of the being before reanimation. A whole pack of zombies can overpower and dismember a man in seconds. Zombies' abilities usually depend on the condition of their corpses. The stronger the physical body, the more powerful the Zombie would be. In addition, Zombies can also be influenced by the type of conditions they are situated in, such as high or low temperature environments.

Trivia

 * The only way to 'kill' a Zombie is to behead the reanimated corpse. This method also guarantees that the dead do not turn into Zombies if the beheading is performed on the normal corpse before they are turned into one.
 * It is noted that a gathering of undeads like Zombies can form stronger undeads, thus the gathering of stronger undeads can form even stronger undeads, so on and so forth.
