Crabbe and Goyle

Harry Potter Character Guide
Vincent Crabbe and Gregory Goyle are Slytherin students in Harry's year; both of their fathers, Crabbe Sr and Goyle Sr, are Death Eaters. Due to their size and strength, the pair act as Draco Malfoy's minions and serve to do Malfoy's bidding, especially to intimidate fellow students. Both are entirely lacking in introspection or curiosity, though Crabbe is shown to be significantly smarter than Goyle. They seem unable to make up their own minds or to see things their own way.
Crabbe and Goyle make their first appearance as new Slytherin Quidditch Beaters in the opening match against Gryffindor in their fifth year; after Harry catches the Snitch, Crabbe vents his frustration by purposely hitting a Bludger into Harry's back and knocking him off his broom, for which he receives the light punishment of writing lines. They do not return to the team the following year, as they regularly serve as Malfoy's lookouts during his forays into the Room of Requirement. After Malfoy leaves the school following the death of Dumbledore just before the end of the term, Crabbe and Goyle are left in a state of loneliness.
The three of them are reunited in Harry Potter and the Deathly Hallows. Both of them speak for the first time, Crabbe's voice being described as oddly soft for someone with his huge frame and Goyle's voice is described as simply a grunt. Crabbe has sided with the Death Eaters with more conviction than either Goyle or Malfoy, and becomes increasingly independent of Malfoy, well aware of the Malfoy family falling out of favor with Voldemort. The pair have developed into surprisingly powerful wizards.
Crabbe and Goyle are mentioned as having excelled in inflicting the Cruciatus Curse on other pupils who had received detentions under Amycus Carrow's direction-- according to Neville Longbottom, it was "the first time they were the best in anything". During the fight for the Horcrux diadem with Harry, Ron Weasley and Hermione Granger in the Room of Requirement, Crabbe defies Malfoy's order to not kill Harry and casually throws around the Avada Kedavra curse. Finally, he summons magical fire and turns the room into a blazing inferno, but it quickly rages beyond his control and leads to his death and the destruction of the Horcrux. Goyle is knocked unconscious during the ensuing fight, but is rescued, along with Draco, by Harry, Ron and Hermione.
