Gregory Goyle

Gregory Goyle is in the same year as Harry Potter at Hogwarts. Along with Vincent Crabbe, he is a thuggish crony of Draco Malfoy. He is widely considered to be extremely stupid. He nearly fails his exams in his first year and is not able to give Dolores Umbridge a simple answer after being questioned about Hagrid's lessons. Goyle, along with Crabbe, fails his Defence Against the Dark Arts O.W.L. in his fifth year. He was impersonated by Harry Potter using the Polyjuice Potion in Harry Potter and the Chamber of Secrets. His father, Goyle Sr, is a Death Eater.
