Pegasus ponies featured rarely in the series. Werewolves The werewolf is a humanoid wolf-like creature that can exist only for a brief period around the full moon. At any other time, a werewolf is a normal human. However, the term werewolf is used for both the wolf-like creature and the normal human. A werewolf can be distinguished from a true wolf physically by several small distinguishing characteristics, including the eyes, claws, fangs, ears, snout, and tufted tail. A person becomes a werewolf when bitten by another werewolf in wolf-form. Once this happens, the person must learn to manage the condition. The Wolfsbane Potion controls some of the effects of the condition; by allowing the sufferer to maintain their human mind in wolf form, it prevents them from harming others. The potion tastes horrible and very few are skilled enough to brew it, and according to Lupin, the addition of sugar to the potion renders it useless and inert. Nothing discovered in the wizarding world can completely cure a werewolf. Most werewolves live outside normal society and steal food to survive. They generally support Voldemort, who they think will give them a better life, since they are shunned by the wizard community and are both feared and hated by the common witch and wizard. Remus Lupin is the only known exception to this. There are only three known werewolves in the Harry Potter series: Lupin, Fenrir Greyback and an unnamed wizard who was in the same ward as Arthur Weasley in St Mungo's Hospital for Magical Maladies and Injuries. While Bill Weasley gets attacked by Greyback during the Battle of the Astronomy Tower in Half-Blood Prince, he is not a werewolf. Although Bill had a number of side-effects from the attack, including a scarred face and a new love of very rare steak, he does not become a werewolf as Greyback was in human form at the time of the bite. The condition of Lycanthropy can be hereditary, but (as seen in the case of Teddy Lupin), it is not necessarily so.
