Harry Potter and the Deathly Hallows
by J.K. Rowling
House: Slytherin, 7th Year
Goyle is pretty much a non-entity; he's Malfoy's follower, and all he does is follow. It seems like he may have gotten some ideas from the Carrows' teachings at Hogwarts, like Crabbe, but he's Disarmed before he has a chance to do any damage. He, like Malfoy, gets saved from the terrible fire in the Room of Requirement, but we don't see him afterwards.
