Shapeshifters

Shapeshifters are a race of supernatural creatures who can take the form of anyone else.

Biography
They have been encountered by Hunters and by Sam and Dean Winchester. Shapeshifters are fairly common. Shapeshifters are human like creatures that start out human, but later learn how to change their form to look like anyone they want.

Shapeshifting, also known as transformation or transmogrification, is a change in the form or shape of a person, especially a change from human form to animal form or a change in appearance from one person to another.

When a Shapeshifter takes the shape of the person they choose to change into, they literally shed their skin, teeth and nails. When they change into the persons physical appearance, they access the thoughts of the person they are mimicking.

The only thing that can kill a Shapeshifter is silver. A silver bullet or blade to the heart.

Hunters usually abbrivent there names to just shifters.
