Anthony Goldstein

Anthony Goldstein is a Ravenclaw student in Harry's year, and is close friends with housemates Michael Corner and Terry Boot. His series debut comes in Order of the Phoenix, in which he becomes a Ravenclaw prefect, and joins Dumbledore's Army after accompanying Michael to the initial meeting at the Hog's Head. He has the least dialogue of any of the D.A. members; his only line in the entire series is "Hear, hear" following Hermione's criticism of Umbridge's teaching curriculum during the first meeting. Zacharias Smith's numerous attempts to disarm Anthony during one D.A. meeting are comically interrupted by the Weasley twins. Anthony is one of six D.A. members who assist Harry against Malfoy, Crabbe, and Goyle as they attempt to ambush Harry on the Hogwarts Express at the end of the school year. He goes unmentioned in Half-Blood Prince, but returns in Deathly Hallows as one of many D.A. members holed up in the Room of Requirement who enthusiastically greet Harry upon his return to Hogwarts, prior to the group entering final battle.
Anthony was initially a Hufflepuff on Rowling's original pre-canon classlist that she created prior to the completion of Philosopher's Stone.[3] He has yet to appear in any of the films, but was included in the Order of the Phoenix video game
