In Harry Potter and the Deathly Hallows, Greyback leads a gang of Snatchers, Dark wizards looking for Muggle-borns and "Undesirables" in exchange for gold. When Harry accidentally uses Voldemort's name after it has been made taboo, Greyback is alerted and his gang attacks their camp. Harry, Ron, and Hermione are kidnapped by the Snatchers and are taken to Malfoy Manor. Bellatrix Lestrange promises Hermione to Greyback in return for his services, but the prisoners fight their way out and escape, Greyback being hit by a triple Stunning Spell. Greyback later agrees to aid Voldemort in the Battle of Hogwarts. During the battle, Hermione, using a blasting curse, prevents Greyback from attacking an injured Lavender Brown, and a crystal ball thrown by Professor Trelawney stuns him. He rejoins the battle in time for the Death Eaters' last stand, when Ron Weasley and Neville Longbottom combine forces to take him down.
