M.o.M Classification: xxxxx (Known wizard killer / impossible to train or domesticate.) About the classification: This classification refers, of course, to the Werewolf in its transformed state. When there is no full moon, the Werewolf is as harmless as any other human. For a heartrending account of one wizardís battle with Lycanthropy see the classic Hairy Snout, Human Heart by an anonymous author (Whizz Hard Books, 1975)

A werewolf in the Harry Potter series is a human who, at the full moon, transforms into a vicious wolf.

The werewolf is a most unusual creature in that it doesn't technically exist except for a brief period of time around the full moon. At any other time, a werewolf is a completely normal human. However, the term werewolf is used for both the wolf-like creature and the normal human. Remus Lupin is a werewolf by definition even if he isn't in the actual form of the wolf.

A werewolf comes into being when a person is bitten by another werewolf. Once this happens, the person must learn to manage the condition. Modern potion-making has come up with a draught called Wolfsbane Potion which controls some of the worst effects of the condition. Wolfsbane Potion is quite difficult to make, even for fully qualified wizards, and is said to have a rather disgusting taste. Nothing will completely cure a werewolf, unfortunately.

A werewolf can be distinguished from a true wolf physically by several small distinguishing characteristics, including the pupils of the eyes, snout shape, and tufted tail.

There are only three known werewolves in the series: One is Remus Lupin, one is an unnamed character who was in the same ward as Arthur Weasley in St Mungo's Hospital for Magical Maladies and Injuries, and the third one is Fenrir Greyback, a Death Eater.

Most werewolves live outside of normal society and steal to eat. They usually support Voldemort, who they think will give them a better life. Lupin is an exception to this.

The Werewolf is found world wide, though it is believed to have originated in Northern Europe. Humans turn into Werewolves only when bitten. There is no known cure, though recent developments in Potion-making have to a greet extent alleviated the worst symptoms. Once a month, the otherwise sane and normal wizard or Muggle afflicted, transforms into a murderous beast. Almost uniquely among fantastic creatures, the Werewolf actively seeks humans in preference to any other kind of prey.

Werewolves spend most of their time as humans (whether wizard or Muggle) once a month, however they transform into savage, four-legged beasts of murderous intent and no human conscience.

Werewolves have been shunted between the Beast and Being divisions for many years; at the time of writing there is an office for Werewolf Support Services at the Being Division, whereas the Werewolf Registry and Werewolf Capture Unit fall under the Beast Division.
