Wendigo

A Wendigo is a formerly mortal demonic creature that can transform between a human and demonic form. It hunts during the three nights of the full moon, seeking to devour the hearts of its victims. Those who survive its scratch become Wendigos themselves.

The Wendigo seeks victims with AB negative blood, who are in love or at least those who have good hearts. When victims are turned into Wendigos, they can only be turned back by destroying the creature who turned them. Its only known weakness is fire.

Book of Shadows
There were two entries on the Wendigo in the Book of Shadows. The first explains what a Wendigo is and how the first Wendigo came to be, the second entry discusses how one can unbecome a Wendigo if transformed into one.

The Wendigo
The Wendigo is a non-dead creature

that roams the earth destroying the good-

hearted and those in love. His fate

is to wander the Earth feasting on

human hearts.

The first Wendigo was a mortal who

was betrayed by his sweetheart.

In revenge for the treachery, he slew his

love and ate her heart. Rather than

savour the warmth of revenge, his heart

was in turn, turned to ice.

During daylight hours and the phases

of the moon, the Wendigo looks as you

or I.

Beware the Wendigo on the three

days of the full moon when his strength

and appetite are greatest.

Beware being attacked and injured.

He duplicates himself by slashing, but

not killing his prey.

c.f. Desiderata.

Unbecoming the Wendigo
Destroy the Wendigo by melting

his heart of ice. Fire is the key

Show no mercy, he will show

none to you. If a person has

been injured but not slain by the

Wendigo, said person will only

be made whole by the complete

destruction of the Wendigo.

Powers and Abilities
Active Powers Other Powers
 * Limited Shapeshifting: The ability to change between a human and a demonic form. Wendigos transform during the three nights of the full moon and cannot control it.
 * Super Strength: The ability to possess physical strength much greater than that of a normal person.
 * Sensing: The ability to determine the location of other beings. Wendigos can sense potential victims with an AB blood-type and are either in love or capable of giving love.
 * Power Granting: The ability to grant powers to other beings. When a Wendigo scratches its victims and they survive, they infect them with their curse.
 * Immortality: The ability to possess an infinite lifespan and an arrested aging process. It is possible that Wendigos are immortal, as the Book of Shadows decribes them as non-dead.

Notes and Trivia

 * The Wendigo is based on the Wendigo of Native American legends, though they also share similarities to a Werewolf.
 * Unlike most demonic infections, a victim of the Wendigo retains his or her original powers, as shown when Piper froze a flare as a Wendigo.
