Werewolf

In the myth, werewolves are described as dangerous and cruel beasts, that don't care about anything or anyone else than themselves. But in the series werewolves aren't so different of humans. They can care for others, feel compassion, sorrow, happiness and even love. In the series, werewolves don't change appearance at all. Normal werewolves' powers grow 2 times bigger on fullmoon than their powers are normally, and only person whose powers grow 4 times bigger than they're normally, is Jake Carter, formerly known as The Biter; a werewolf lurking in the shadows of New York,killing people.

The first werewolves
The very first werewolf in the world was Chase, who lived on the 14th century in Europe. When he was young, a wolf bit him, turning him into a werewolf. He kept it as a secret for a while, but then he told his three brothers, then turning them into werewolves too. Then Chase decided to destroy the village; the brothers burned the houses and killed all of the people in the village; they even killed their own parents.
