The Greyback minifigure wears a black suit, black pants, a belt, and a gray shirt which parts to show his hairy, werewolf-chest. His face is covered with matted fur, whiskers and bared teeth in a savage grin. He has slicked back brown hair. He has silver eyes with white pupils. In the books his character is said to have smelled of "dirt, sweat, and blood".
Greyback, unlike other werewolves, is savage on bloodthirsty, even biting humans in the day without the full moon. He bit Remus Lupin when he was a child and was therefore responsible for Lupin's transformation into a werewolf. He also attacked Bill Wealsey, but not on a full moon so Bill was not completely infected.
He and a group of Snatchers kidnapped Mr. Ollivander, the wand-maker, Griphook, and Luna Lovegood in Harry Potter and the Deathly Hallows. Even though he was unofficially considered a Death Eater because he hunted down and turned in enemies of Voldemort, he never got the Dark Mark branded on his arm as he was never part of Voldemort's inner circle.
During the Battle of Hogwarts, Hermione Granger used a spell to blast him away from Lavender Brown (who he had killed) as the werewolf sunk his teeth into her leg. He was hit on head with a crystal ball from Professor Trelawney. He escaped and dueled Neville Longbottom, Ron Weasley and another student, who eventually defeated him.
- The opposite side of Greyback's head depicts a more serious evil look as opposed to his jubilant evil look.
- One of the shop images of Greyback for 10217 Diagon Alley shows him with an orange chest, but this is not how it turns out to be in the set.
