remus lupin'in kurtadam olmasına sebebiyet veren kişidir. ayrıca
bill weasley'i de ısırmıştır.
kendisi hakkında lupin şöyle demiştir:
"fenrir greyback is, perhaps, the most savage werewolf alive today. he regards it as his mission in life to bite and to contaminate as many people as possible; he wants to create enough werewolves to overcome the wizards. voldemort has promised him prey in return for his services. greyback specializes in children... bite them young, he says, and raise them away from their parents, raise them to hate normal wizards."
gereksiz bilgi: adının esin kaynağı norse mitolojisindeki
