Blaise Zabini in Harry Potter and the Half-Blood Prince

Blaise Zabini

House: Slytherin, 6th Year

Blaise is a Slytherin who, like Draco, holds contempt for Muggle-born wizards and witches like Hermione. He is one of Slughorn's favorites:

Zabini, who was interrogated after McLaggen, turned out to have a famously beautiful witch for a mother (from what Harry could make out, she had been married seven times, each of her husbands dying mysteriously and leaving her mounds of gold). (7.160)
