Vampires

 Vampires''' are a race of blood drinking supernatural creatures that were once human. They have been encountered by the Winchesters, Gordon Walker and other hunters. Little has been revealed about vampires, such as their organization, weaknesses and their origin - all vampires originate from the Alpha Vampire.

They have appeared as monsters of the week in 'Dead Man's Blood', 'Bloodlust' and 'Live Free or Twihard'.

Characteristics
A vampire's appearance is that of a normal human. However, they all have common features, such as sharp, pointed, retractable teeth that emerge from their gums and extend beyond their human teeth, and immortality. They live forever, and several depicted vampires are hundreds of years of age or older. Their diet is based strictly on blood, and while human blood is prefered, they can survive by ingesting the blood of other animals (although one such vampire, Lenore, refers to cow blood as 'disgusting'). Vampires can only be killed by beheading, and then, they leave behind a corpse that can be examined to find their vampire teeth.

Type of Hierarchy
Vampires are organized into nests, with eight to ten vampires residing in each, with a mate for life. The younger members of the nest typically do the hunting for their elders, bringing back humans to be fed upon for days or even weeks.

Reproduction
Vampirism is a blood-borne pathogen, spread by the ingestion of infected blood or by its direct introduction to the human blood stream. These are the only known methods of infection, since many hunters are seen getting splashed in the face with vampire blood without being turned. This means that the virus doesn't enter a person's system through the eyes, nose or unbroken skin. It may also mean that, in terms of ingestion, a certain quantity of the contagion is required to cause infection, considering getting splattered blood on the lips may result in some entering the mouth, becoming mixed with saliva, and winding up swallowed. These limitations are very beneficial to hunters due to the fact that killing a vampire can only be a gory experience.

Cure
Vampirism is rarely curable, with the only known cure being a ritual recorded by an ancestor of the Campbell family of hunters. The ritual calls for the blood of the new vampire's sire, and will not work if the subject has fed on human blood. The reversion is painful, but no secondary effects are retained.
