Gregory Goyle

Gregory Goyle was no cleverer than his best-friend Vincent Crabbe and he was equally as thuggish. Together the two Slytherins followed Draco Malfoy around, making sure that other students knew that they were bigger, better and more powerful than them. The son of a Death Eater, Goyle and his friends were particularly unkind to Muggle-born students and more than once.
