Crabbe was one of the first students to be sorted into Slytherin House during his year at Hogwarts School of Witchcraft and Wizardry. He was also one of the first to be chosen by Lord Voldemort as a Death Eater, along with Goyle and Malfoy. During his time at Hogwarts, Crabbe played on their Quidditch team as a Beater, alongside Vincent Goyle and Gregory Goyle (who played as Bludgers). As well as being a member of the team, Crabbe also joined the Slytherin House Quidditch Team under the leadership of Captain Marcus Flint (alongside Malfoy). Crabbe fought against the Order of the Phoenix during both wizarding wars. He was present at the First Wizarding War, where he fought against the Order of the Phoenix. While Draco’s mother Bellatrix Lestrange was distracted with fighting Harry, Ron Weasley, and Hermione Granger in the drawing room, Crabbe and Goyle were attacked by Fenrir Greyback who bit them both on their arms and necks causing them to transform into werewolves themselves. They were found dead after Harry killed Greyback. Crabbe may have been referencing his uncle Vincent Crabbe Sr., who was a member of the original Death Eaters before he was imprisoned in Azkaban for life for torturing Frank and Alice Longbottom into insanity.
