Description
Fenrir Greyback was the most savage and feared werewolf in the wizarding world. Unlike most werewolves, Greyback actively embraced his condition, positioning himself as close to his victims as possible during full moons and targeting children in particular. He was not a full Death Eater (he did not bear the Dark Mark), but served as one of Voldemort’s most terrifying allies.
History
Greyback was responsible for infecting Remus Lupin with lycanthropy when Lupin was a young boy — an act of revenge against Lupin’s father, who had insulted werewolves. Greyback deliberately attacked Bill Weasley during the Battle of the Astronomy Tower in 1997, scarring him permanently (though Bill did not become a full werewolf since Greyback was in human form at the time).
During the Battle of Hogwarts, Greyback attacked Lavender Brown. He was subdued by a crystal ball hurled by Sybill Trelawney and a curse from Hermione Granger.
