Gregory Goyle is one of Draco Malfoys thuggish cronies. Goyle has short, bristly hair that extends down onto his forehead. His eyes are small, dull, and deep set, and he speaks with a low, raspy voice. Hes a mean bully who enjoys whatever chance he gets to boss people around, whether as a member of Umbridge's Inquisitorial Squad in his fifth year or using the Cruciatus Curse on other students in his seventh. Polyjuice Potion to turn someone into Goyle is the khaki color of a booger. Goyles interests include chuckling trollishly, smirking, laughing syncophantically, cracking his knuckles, flexing his muscles, sniggering stupidly, and rubbing his knuckles in a menacing way. He doesnt like writing. Why is that not surprising?. Goyle's father is a Death Eater. - gotten from the Harry Potter Lexicon (http://www.hp-lexicon.org)
