The Crabbes tend to have prejudices against Muggles and Muggle-borns, like the Blacks, to whom they are related. During the First and Second Wizarding Wars, they were allied with Lord Voldemort.
- Irma Black née Crabbe – wife of Pollux Black
- Mr. Crabbe – one of the clumsier, stupider Death Eaters; presumably killed or imprisoned in Azkaban.
- Vincent Crabbe – an overweight bullying Slytherin student in Harry Potter’s year at Hogwarts; close friends with Gregory Goyle and Draco Malfoy (who are both pure-blood); accidentally killed by his own Fiendfyre during the Battle of Hogwarts.
