Theodore Nott

Theodore Nott is a student in Harry Potter's year at Hogwarts who is sorted into Slytherin House. His father, identified only as Nott, appears as a Death Eater toward the end of Harry Potter and the Goblet of Fire when he responds to Lord Voldemort's summons and is captured at the end of Harry Potter and the Order of the Phoenix during the Battle at the Department of Mysteries.

Theodore appears briefly in Harry Potter and the Order of the Phoenix when he appears as a "stringy Slytherin", one of the three students (the others being Harry and Neville Longbottom) who can actually see the thestrals, the skeletal, winged, horse-like creatures visible only to persons who have witnessed death. It is presumed that Theodore's sympathies lie with the Death Eaters.
