Werewolf

Werewolves are cursed humans that turn into murderous wolf-like beasts.

Biology and traits
In their transformed states, Werewolves resemble upright-standing bipedal wolves.

Infection and reproduction
The Werewolf curse is transferred through two methods. Primarily it is when the genetic mutation is passed from parent to chlid. There is no absolute guarantee that the child of a cursed person will inherit the gene, however. Studies show that as long as one of the parents is fully human, there is a fifty-fifty chance that the child will be human as well. The gene will not excert itself until puberty. This allow the child to live a perfectly normal life up to the teen years while his or her parents will spend that same period worrying of what will become of their child. In cases where both parents carry the mutated gene, it is certain that the child will be a Werewolf as well.

The other means of transfering the curse is through infection of the bloodstream from a werewolf bite. The gene for the Werewolf infection is carried through saliva. Once the gene infects the human victim, there is no known cure. This method is incredibly rare since Werewolves hardly ever leave their victims alive.
